South Korea's Rise as a Global Shipbuilder
During the World War II period, shipbuilding rose into one of the most critical sectors for most countries in continental Europe and the U.S. In these regions, shipyards represented the backbone of waterfront businesses, providing a lifeline for many coastal communities. But despite that demand for construction of new vessels is still high, shipbuilding in the West has hit an inflection point. Overall, shipbuilding production has fallen to historic lows, a case in point being the U.S where shipyards capable of building large vessels have declined by more than 80 percent since the 1970s.
The same cannot be said of the Asian region, where massive shipbuilding complexes are the world leaders in supplying modern ships. China, South Korea and Japan continue to maintain the top three position in the global shipbuilding market. But to understand this Asian monopoly in shipbuilding, we must break it down at the country level.
In this case, South Korea has the most intriguing case of how it developed its shipbuilding and could offer valuable insights for the developing and middle power countries vying for a similar position. In a new research paper published in the Marine Policy journal, Dongkeun Lee, a Korean Navy(ROKN) reservist officer and a researcher based at the College of Asia and the Pacific, in the Australian National University, Canberra(ACT), explores the unique case of the Korean shipbuilding rapid development between 1960s to the 2000s.
Lee characterizes the history of the South Korean shipbuilding as relatively shorter compared to other major shipbuilding countries. For this reason, it defied several critical factors historically believed to be requisites for any country vying for a dominant position in global shipbuilding.
First, South Korea is a late industrialized middle power country with limited resources and population. This is a contrast to most major shipbuilding countries including China, the U.S, Russia and Japan, which have a long history of shipbuilding due to early industrialization during the 18th and 19th centuries. In addition, these countries have substantial resources such as manpower and a strong economy to allocate to the shipbuilding industry.
Another notable exception is that some countries that fall into the same economic category as South Korea, such as Saudi Arabia and Australia, lack sufficient shipbuilding capabilities to fully meet the demands of their navies. Partly, for such late industrialized countries without sufficient man power, it is not economically rational to build indigenous shipbuilding industries because of the high initial costs.
It then begs the question how South Korea managed to break these barriers to have shipbuilding as one of its major economic mainstays. Indeed, this topic has been covered widely in the past. The question has been answered by pointing to government subsidies that protected South Korean shipbuilding from foreign competitors. South Korea’s military dictator Park Chung-hee, who served as the country’s president from 1963 to 1979, heavily subsidized the industry, under the so-called chaebol companies to boost the national economy.
In Lee’s recent analysis, he was for the first time able to utilize documents from South Korea’s presidential archive, which was established back in 2007. The documents offer valuable insights on the intentions behind Park’s decision to subsidize Korean shipbuilding.
Notably, in 1970s sea-based North Korean military provocations compelled South Korea to develop sea power. This would see South Korea start the implementation of the Patrol Boat Acquisition and Domestic Building Policy. It would herald South Korean indigenous warship-building industry, which is still supported by the current defense strategy. During the same period, the government also invested in expanding existing shipbuilding infrastructure for commercial vessels. Some of these shipyards are still in use today including the Okpo shipyard by Hanwha and Ulsan shipyard by Hyundai Heavy Industries(HHI).
In fact, this represents one of the unique characteristics of South Korean shipbuilding, where the government concurrently supported commercial and warship building capabilities. Chaebol companies that had received government subsidies during the 1960s became important players in warship construction during the 1970s- 1980s.
Meanwhile, as many western countries discontinued their shipbuilding during the end of the Cold War, South Korea shipbuilding persevered. Increased demand for commercial ships throughout 1990s-2000s also created a robust ecosystem for the Korean shipbuilding to thrive.
While Lee acknowledges that the South Korean model may not be sufficient for other developed countries, he singles out government subsidies as a critical starting point for developing the shipbuilding capabilities. In the case of economies such as Australia and Canada, where labor costs are high, one viable option for government subsidies could involve building high-value commercial ships alongside warships. A good example is Italy’s Fincantieri, which not only builds cruise ships but also warships.
Romania Begins Insolvency Against Damen Mangalia Shipyard
The long-running battle between Damen and the Romanian government over the operations of the Mangalia shipyard on the Black Sea took a new step as a court in Constanta initiated an insolvency procedure. An administrator has been appointed to look for a recovery plan for the shipyard.
The Netherlands’ Damen took operational control of the shipyard in 2018 with high expectations for the operation which remained 51 percent owned by the government. The yard had been in operation since 1976 known for 20 years as the 2 Mai Mangalia Shipyard. South Korea’s Daewoo launched a joint venture to operate the yard in 1997 and expanded the operations with a focus on commercial ships. In the next decade, the yard delivered over 200 ships.
Damen highlighted that the yard had three large drydocks and it was the largest in its group. Damen has a long history with Romania operating the Galati shipyard since 1999. Plans for Mangalia called for expansion and further investment in areas such as the outfitting capabilities.
Mangalia however was hit hard by the downturn in the shipping industry with the company citing the decline in demand from the offshore sector. They also reported increased competition from shipyards in Asia. When the pandemic hit the industry, Damen launched a plan for the reorganization of the yard. Plans for downsizing the operation and refocusing the business were not well received in Romania where it was reported Damen would reduce headcount at Mangalia by over 200 and at Galati by nearly 650 people. The company however in early 2023 highlighted a recovery including two HVDC (High-Voltage Direct Current) offshore transmission projects at the yard, both of which were being constructed under contracts with Aker Solutions as the main EPCI contractor.
The Romanian government in June 2023 passed a new law that gave it control of Mangalia and limited Damen’s involvement to a minority investor. The company protested but unable to resolve issues with the government moved in August 2023 to terminate the joint venture. Reports were at the time the yard was employing 1,500 full-time individuals plus contractors employees and flex-time staff.
Damen in April 2024 sought to take the case to an international arbitration court in Vienna. Damen was reported to be seeking compensation to end the joint venture and its loss of control of the yard. Reports in the Romanian media said that Damen had guaranteed more than $170 million in loans for the shipyard.
The shipyard filed for a bankruptcy proceeding at the end of May and last week the court decided to proceed with the insolvency. The administration set the first meeting for the end of August while saying it would be studying the business to understand its weaknesses and working to define a recovery strategy. They said the aim was to provide as much stability and clarity in a complex situation.
Damen’s operations at Galati are separate from Mangalia where it was in a joint venture.
Container Fire Containing Toxic Phosphorus Causes Antwerp Port Evacuations
A container fire in the Port of Antwerp prompted evacuations and a suspension of operations in sections of the container terminals overnight as emergency services worked to neutralize the danger. Operations we stopped for 12 hours with vessels evacuated as a precaution.
The Waasland fire brigade received reports of the container fire at 7:30 p.m. on Sunday night in the Beveren area which includes the Deurganckdok, one of the primary container handling areas of the port. The container burning was determined to contain yellow phosphorus. A commonly used chemical in fertilizer and other industrial applications, it is extremely toxic. Exposed to air it is flammable and inhaled it causes burning and in small amounts, it can be deadly to humans.
The MPET terminal used by MSC containerships and the DP World facility were both evacuated as a precaution. A ship moored in the port was also evacuated and all vessel traffic at Deurganckdok was also temporarily halted.
The fire service reported it was working with the chemical company BASF and the port. After approximately an hour, they were able to reduce the perimeter but continued to work to secure the container. As such, operations at MPET and Deurganckdok remained suspended.
As of 0730 Monday morning, the fire service was reporting that the container had been moved to a “safe location.” The port said that they were doing everything possible to restart all activities as quickly as possible.
It was the second incident this month to interrupt operations at the container terminals in the Port of Antwerp. On June 6, port officials detected oil in the water that they determined was coming from a bunkering operation at the container terminal. A survey showed 20 ships, both sea vessels and barges, were polluted in Deurganckdock. Oil was also detected in the fairway and on the quay walls.
Contaminated ships were prevented from leaving the port until they had been cleaned and the fairway also needed to be cleaned. Operations at one of the port’s locks were also suspended. Some ships were able to be cleaned quickly and proceed but operations continued to be impacted until June 18 when the Port of Antwerp reported that the cleanup operation had been completed.
CRIMINAL CAPITALI$M
Two Lockheed Subsidiaries Settle Charges of Overbilling U.S. Navy
Two subsidiaries of aerospace giant Lockheed Martin have agreed to pay $70 million to settle allegations that they overcharged the U.S. Navy for aircraft parts, according to the U.S. Department of Justice. The case was originally brought on behalf of the U.S. government by a whistleblower who worked at one of the firms involved.
The case centers on activities at Sikorsky Support Services Inc. (SSSI) back in the 2000s, when the company was a division of United Technologies. At that time, SSSI held a contract to supply aircraft maintenance and parts for the U.S. Navy's T-34, T-44 and T-6 training aircraft. To obtain parts, it subcontracted with another division of United Technologies, Derco. The legal problem arose from an internal agreement that these two divisions of the same company had with each other: one division of United Technologies (Derco) bought the parts, then sold them to a different division of United Technologies (SSSI) at a 32 percent markup. The DOJ alleged that SSSI knowingly used Derco's inflated invoices to bill the Navy, ultimately charging the taxpayer 32 percent more than the market price of the parts.
In 2011, whistleblower Mary Patzer filed a civil suit against Sikorsky Aircraft, SSSI and Derco, alleging that this billing arrangement violated the False Claims Act. The Department of Justice intervened in the case in 2014 and took over the lawsuit. DOJ's legal team claimed that SSSI and Derco's top managers engaged in "a deliberate scheme to defraud the United States through the use of an illegal cost-plus-a-percentage-of-cost subcontract." In its complaint, the government claimed that Derco's then-president was aware that this arrangement was illegal, and pursued it anyways - even though the supply contract with the Navy made clear that there could be no markups on "the actual price of parts, material and shipping costs."
Sikorsky, SSSI and Derco contested these allegations, but the district court ruled in favor of the U.S. government, finding that the 32 percent markup violated a federal statute barring this form of subcontracting price structure. Last week, the two sides reached an agreement to settle the matter for $70 million.
“The U.S. Attorney’s Office is committed to preventing fraud and protecting taxpayer money,” said U.S. Attorney Gregory J. Haanstad for the Eastern District of Wisconsin. “Government contractors must put compliance with the law ahead of profits. This settlement makes the United States whole for the inflated costs arising from SSSI’s and Derco’s illegal subcontract deterring future violations of the law.”
When Lockheed Martin purchased Sikorsky Aircraft from United Technologies in 2015, it acquired Derco and SSSI, and it inherited their ongoing litigation. The events alleged in the lawsuit predated Lockheed's involvement with either company.
NTSB Homes In on Connector Device From Dali's Switchboard
The NTSB has issued an update on its investigation into the disastrous allision of the boxship Dali with the Francis Scott Key Bridge in March, which destroyed the span, killed six workers and blocked off Baltimore's federal shipping channel for months.
The container ship lost electrical power twice as it approached the bridge on the accident voyage. Both times, mission-critical circuit breakers that connect the ship's generators to the rest of the electrical distribution system tripped (opened), turning off all the lights - even though the generators continued to run.
The loss of electrical power temporarily disabled the ship's rudder and forced a shutdown of the main engine, causing the Dali lose propulsion and heading control as she approached the bridge's main spain. Though backup control of steering was restored when the emergency generator started, it was too little and too late to prevent an allision with the southwestern bridge pier. Dali's momentum crushed the pier on impact, collapsing the entire bridge truss in seconds. The damage will likely take years to restore.
According to NTSB, the first set of breakers (HR1 and LR1) tripped when the Dali was just three ship lengths away from the bridge, causing the first blackout. With help from the OEM, the crew and other experts, NTSB has been examining these breakers closely at the component level to determine what might have gone wrong.
During testing, the investigators noticed "an interruption in the control circuit for HR1's undervoltage release." The undervoltage release is a device that trips the breaker when the voltage falls below a set threshold.
The team pulled a terminal block - a female connector socket for plug-in components - out of the control circuit for the breaker undervoltage release (illustration at left, courtesy WAGO). Two sections of the control wiring associated with this terminal block were also removed from the switchboard, and these components were taken back to NTSB's laboratory for further testing.
The agency did not release further information on its findings, and it emphasized that the update should not be taken as a conclusion about the root cause of the casualty. The broader investigation into the allision is still under way; while NTSB has no formal timeline for completion, based on the length of past inquiries, the process often takes approximately one year.
Video: Containership Dali Underway Three Months After Baltimore Allision
After a slight delay over the weekend, the containership Dali which became infamous for her allision with the Francis Scott Key Bridge in Baltimore got underway on Monday morning bound for Norfolk, Virginia. It is a carefully choreographed exercise as the vessel remains heavily damaged including without anchors and with debris and containers still aboard.
The U.S. Coast Guard reports she is traveling under her own power with a full crew of 22 aboard as well as six salvage experts from Resolve Marine. Four tugs are accompanying the vessel on the trip which is expected to take 16 to 20 hours. The Coast Guard cutter Sailfish from Norfolk is maintaining a 500-yard safety zone around the ship and the salvage vessel Inceptor from Resolve Marine is following the trip. AIS signals show her traveling at 8 to 10 knots.
Strong safety protocols are being enforced during the transit as well as monitoring by the Coast Guard. One concern is that some of the debris might come loose and fall overboard, although most of the damage at the bow was secured or removed and a tarp was placed over some of the damaged areas. As an added precaution, the Maryland Transport Authority reported that traffic would be stopped on the Bay Bridge crossing the Chesapeake near Annapolis while the vessel transits the area.

The delays included last-minute arrangements for two additional crewmembers, both cadets, to leave the vessel. Initially, an agreement was made for eight ratings to return home to India and Sri Lanka as long as they would be made available or later depositions. The cadets were added to the agreement. The Dali had been at the Seagirt Terminal in Baltimore for the past 35 days for salvage operations after being removed from the bridge debris.
According to media reports, four of the original crewmembers are staying with the vessel during the trip to Norfolk. Synergy Marine arranged for a replacement crew to join the vessel last week. Seven crewmembers were being transferred to hotels or apartments in the Baltimore area to await depositions and the legal cases. The four others presumably will be returning to Baltimore as they are also parties to the various legal cases and potential actions by the U.S. Department of Justice.

Once the Dali reaches Virginia, she will be first going to the Virginia International Gateway in Portsmouth on the Elizabeth River south of Norfolk. Virginia International Gateway is a privately owned terminal leased by the Virginia Port Authority. It is one of the VPA’s two main container terminals. There the Coast Guard reports at least 1,500 containers will be offloaded from the Dali to reduce the vessel’s draft.
At a later date, the Dali will again be shifted this time to the Norfolk International Terminal. While in Norfolk the vessel is to receive initial repairs before the owners, Grace Ocean, transfer her to another shipyard likely in Asia for additional repairs.
MOL to Consolidate Dry Bulk Position by Taking Control of Gearbulk
Mitsui O.S.K. Lines will increase its ownership position in Norway’s Gearbulk Holdings as part of the Japanese company’s strategy to consolidate and expand its position in dry bulk shipping. MOL, which reports it is one of the world’s largest shipping companies with a fleet of over 870 vessels, says the transaction is part of its commitment to accelerate revenue growth.
Kristian Jebsen and his family through their holding company Halberton will sell an additional 23 percent stake in Gearbulk to MOL with the deal expected to be completed by January 2025. Gearbulk first has to complete some internal reorganizations consolidating its open-hatch business and a carve-out of other businesses. MOL will increase its position to a 72 percent stake and consolidate Gearbulk as a subsidiary while Jebsen will retain a 28 percent shareholding in Gearbulk.
“By adding Gearbulk's open-hatch segment business to MOL business, we will be able to offer a diverse range of transport services by a broad range of vessel types,” MOL writes explaining the transaction. The company has been an investor in Gearbulk since 1991.
Gearbulk started in 1968 and was one of the pioneers in open hatch gantry crane vessels. The group has built a leadership position in the segment reporting it has the world’s largest fleet of open hatch gantry crane and jib crane vessels. The group has about 65 open hatch and other specialized vessels with the fleet commercially operated by G2 Ocean, a joint venture 65 percent owned by Gearbulk and 35 percent by Grieg Maritime. G2 will continue to operate as before after MOL increases its position in Gearbulk.
Open hatch is a specialized segment of the dry bulk sector. The vessels are designed to transport unitized cargoes such as forest products, bale pulp, non-ferrous metals, aluminum ingots, and steel products. G2 Ocean also transports conventional bulk and project cargoes. The vessels are also designed so that the cargo can be loaded on top of the hatch or deck, allowing the transport of heavyweight and oversized cargo such as windmill components.
MOL reports that the consolidation of Gearbulk creates synergies such as enhancing the expansion of the group's business base by adding Gearbulk's worldwide network, creating new business opportunities, and boosting the efficiency of vessel allocation. The company also expects these synergies to significantly differentiate it from its competitors and strengthen its cost competitiveness and customer network.
Vineyard Wind Reaches Milestone as Largest Operating US Offshore Wind Farm
The Vineyard Wind 1 project passed a key milestone today becoming the largest operating offshore wind farm in the United States. Being developed off the coast of Martha’s Vineyard in Massachusetts, project developers Avangrid and Copenhagen Infrastructure Partners celebrated reaching 136 MW on their way to a total capacity of 806 MW.
With 10 of the planned 62 wind turbines now in operation, Vineyard Wind 1 is now delivering more than 136 MW to the electric grid in Massachusetts. It surpasses Ørsted’s South Fork which was completed earlier this year and has a capacity for 132 MW from 12 turbines. These two projects were the first large-scale offshore wind farms to begin construction in the United States, although they will ultimately be surpassed by others including Dominion Energy’s project off the coast of Virginia which started construction in April 2024.
The companies are highlighting that Vineyard Wind 1 currently has installed 47 foundations and transition pieces and 21 turbines, with the installation of the 22nd turbine underway. Unconfirmed reports in the local media asserted that the project has encountered unanticipated challenges and weather in the installation process slowing its progress.
Located 15 miles off the coast of Martha’s Vineyard, Vineyard Wind began offshore construction in late 2022, achieved steel-in-the-water in June 2023, and completed the nation’s first offshore substation in July 2023. Construction flows through the New Bedford Marine Commerce Terminal.
The project marked its first power delivered to the grid on January 2, when Vineyard Wind delivered approximately five megawatts of power from one turbine to the grid. Following that milestone, the project provided power from each of the first five turbines intermittently, as it ramped up to initial operations, which it achieved in February when the project began delivering approximately 68 MW from five turbines to the grid. At the time, they said that nine turbines had been installed and the process of installing the 10th was underway.
Building on the 136 NW currently being delivered, they report additional power will be delivered to the grid sequentially, with each turbine starting production once it completes the commissioning process.
Vineyard Offshore, the JV operator for the project in March 2024 reported it had submitted a proposal for a 1,200 MW offshore wind project to Massachusetts, Connecticut, and Rhode Island in response to the New England states’ solicitation for up to 6,800 MW of offshore wind capacity. The project, which would be located 29 miles south of Nantucket would be Vineyard Wind 2 with a project operational date of 2031.
The zone south on Martha’s Vineyard and stretching west toward Rhode Island and Connecticut and south to the eastern tip of Long Island is the U.S.’s first cluster for offshore wind. The Bureau of Ocean Energy Management has moved forward with the approvals for additional projects in the zone and ultimately it will host approximately 10 large commercial wind farms.
Germany Proceeds with RWE, TotalEnergies, and EnBW for More Offshore Wind
Germany Proceeds with RWE, TotalEnergies, and EnBW for More Offshore Wind
Germany approved another offshore wind project and awarded two more leases as it moves forward on its next tranche for renewable energy from offshore wind with a focus emerging on large clusters. RWE reports it was given the green light for the first phase of a large project in the North Sea while both TotalEnergies and EnBW won leases for offshore sites in the latest auction.
The Federal Maritime and Hydrographic Agency (BSH) announced the decision as it works to move forward with a broad range of renewable energy projects. With over 8.5 GW installed, Germany has the second-largest offshore wind energy capacity in Europe, nearly double that of the Netherlands. The UK, however, remains the leader in Europe at 14.7 GW of capacity, and second only to China.
BSH President Helge Heegewaldt said they are pleased about the completion of the approval process and the progress they are making. "According to the legally defined targets, a total of 30 GW of installed capacity from offshore wind turbines should be connected to the grid by 2030. At the moment we have an installed capacity of around 8.6 GW. With the current planning approval decisions, we have another building block for achieving the goals of the Offshore Wind Energy Act for an efficient expansion of offshore wind energy."
RWE, which already has six wind farms off the German coast in its portfolio, plans to start construction on the first phase of the Nordseecluster A. BSH approved NC 1 and NC 2 which the company reports will permit to implement the first phase of its 1.6 GW cluster. The company has already taken the investment decision and reports it expects to start offshore construction next year. Production of some components has already started.
The Nordseecluster is being built approximately 30 miles north of the German islands of Borkum and Juist. The first phase, which has now been approved, has a total capacity of 660 MW. The 44 wind turbines of Nordseecluster A, each with a capacity of 15 MW, are expected to be fully connected to the grid in early 2027. The second phase, Nordseecluster B, will add another 900 MW of capacity, with commercial operation expected to begin in early 2029. Together, the wind farms in the Nordseecluster will generate around 6.5 terawatt hours of electricity annually.
BSH also concluded its next auction awarding TotalEnergies’s company Offshore Wind One a concession for a location about 75 miles northwest of the German island of Heligoland. It covers approximately 60 square miles. TotalEnergies says this will permit it to build a 3.5 GW offshore wind hub in the North Sea. The new concession adds 1.6 GW of capacity to the 2 GW area the company won last year. It received a 25-year lease which could be extended to 35 years.
EnBW was awarded a lease for an area also approximately 75 miles from Heligoland. Its plans call for a 1 GW wind farm in the North Sea set to enter operations in 2031. The company already operates four offshore wind farms along the German coast and in May 2024 started construction on He Dreiht, which will be the largest offshore wind farm to be built without state funding. Due to enter operations at the end of 2025, it will add 960 MW to the portfolio which consists of approximately 1 GW from the sites in the North Sea and Baltic. EnBW highlights it has been planning, building, and operating offshore wind farms in Germany and Europe for around 15 years. As a company, it wants to expand renewable energy capacity to between 10 and 11.5 GW by 2030 and be climate-neutral by 2035.
Crowley Formally Christens eWolf, its First Electric Tug
Crowley Maritime has formally christened its long-awaited electric harbor tug, the eWolf, in a ceremony in San Diego. The vessel will begin providing commercial services at the Port of San Diego this week.
"The all-electric tugboat is the most technologically advanced vessel of its kind, and eWolf will help our customers and communities reach their decarbonization goals," said Tom Crowley, Chairman and CEO. “We congratulate the people whose tireless dedication brought the eWolf to fruition with our partners at the federal, state and local government, setting a new standard not just in America, but globally."
The small tug packs a considerable punch. Its battery-electric drive can produce 70 tons of bollard pull - more than the conventional tug it replaces. Its six-megawatt-hour battery array has enough power to run the workboat for a full day. For backup and transits, it has two generators on board. In normal operation, it produces zero onboard emissions - a highly-valued attribute for meeting California's stringent air quality standards - and it is expected to reduce NOx emissions by 178 tons and CO2 emissions by 3,100 metric tons during its first 10 years of service.
"Portside communities, like Barrio Logan and National City, breathe more diesel pollution than 90 percent of California communities," said CARB board member Diane Takvorian. "The eWolf will contribute significantly to creating a healthy environment for all."
The eWolf's name is a tribute to the first Crowley tug in California, the Sea Wolf. It was constructed by Master Boat Builders of Alabama, and it was outfitted with an integrated propulsion, electrical and energy storage package from ABB. It was ordered in July 2021, went out on sea trials in December 2023 and was delivered to the operator in late January 2024. Crowley has constructed a microgrid recharging station to keep its batteries topped up.
To get the projet across the finish line, Crowley had support from the port, the local air quality district, the California Air Resources Board (CARB), the EPA and the Maritime Administration.
AI Image Tools May Help Autonomous Ships Drive Safely in the Arctic
[By Sølvi Normannsen]
Imagine an autonomous ship sailing through one of the world’s most extreme ocean areas. Sea ice is everywhere. Fog, snow or rain make visibility extremely poor. Just like ship captains see through their eyes, autonomous navigation algorithms perceive the world through sensors, and bad weather is just as impenetrable for sensors as it is for sea captains.
Getting rid of poor visibility
With the rise of Arctic shipping, something that can remove the bad weather from the images so the algorithms can see the surroundings as if it were a clear, sunny day could be extremely useful. Now, PhD candidate Nabil Panchi at NTNU’s Department of Marine Technology has developed an algorithm that can do just that.
“We have put in place a new piece of the big puzzle for better modeling of sea ice,” Panchi said.
Current AI algorithms work well on clear images, but they struggle when images become blurry or degraded due to bad weather.
Panchi, who is also a naval architect, has used thousands of images from the Arctic to train the new algorithm so it filters out visual impediments such as rain, snow, and fog, as well as water droplets on the lenses of the cameras that many vessels are equipped with.
Panchi is affiliated with the DigitalSeaIce project, which is focused on multi-scale integration and digitalization of Arctic sea ice observations and prediction models. The main objective is to build a digital infrastructure that integrates regional sea ice forecasting models and local ice-related models with shipboard and satellite-based Arctic sea ice and environmental observations.
Understanding the environment via images
“Our work is about understanding the Arctic environment through the use of images. We are creating algorithms that work in all weather conditions” says Panchi.
His research is based on thousands of images taken on a voyage with the research ship Kronprins Haakon in the Arctic during the summer of 2023.
In collaboration with his academic supervisor, Associate Professor Ekaterina Kim, he recently published the article ‘Deep Learning Strategies for Analysis of Weather-Degraded Optical Sea Ice Images’ in the IEEE Sensors Journal.
Panchi and Kim are introducing two ways of helping ships travel more safely in bad weather in the Arctic, by “removing” the weather from images. One uses artificial intelligence to clean up the images, so that existing algorithms work as they should. A slightly more efficient way is to develop new algorithms that work during bad weather.
“Both strategies allow us to understand the Arctic in all weather conditions,” Nabil says.
Cleaned images already in use in cities
Algorithms that can remove weather from images have been in use for a long time, but primarily in urban areas. They are used to develop autonomous cars, and in security and camera surveillance.
Current algorithms that analyze sea ice are largely based on images taken from ships in good weather conditions. The problem is that images from the Arctic are often unclear due to the fog, rain, and snow that are common weather conditions in these waters. These types of images are poor material for the existing algorithms that are designed to understand the Arctic environment.
The algorithms also need to be trained to analyze the type of ice surrounding the ship, so they can indicate where it is safe to break through the ice, and which areas the ship should avoid.
The first open-access dataset of sea ice images
In order to remove fog and raindrops, algorithms must be trained to clean up weather-affected sea ice images. “This area of research had largely been ignored so far. The problem has been limited access to clear images from the Arctic – until now. We hope that our new open-access dataset helps in future development of weather resilient technology,” Panchi says.
Panchi’s supervisor Ekaterina Kim has worked extensively in the Arctic, and in recent years she has been exploring how AI can be adopted to solve some of the challenges that exist in polar regions.
The two NTNU researchers have now made the SeaIceWeather dataset publicly available online. It contains thousands of images and is the first open-access data set for sea ice.
Facilitating safer voyages
“There are very few open-access datasets of this type. A huge amount of work goes into making them. We hope they are used as much as possible,” says Panchi.
Rain on one, clear weather on the other. When fed with a weather image, the AI model removes the raindrops and produces a much clearer image of the ship’s surroundings.
Each picture comes in two versions: a ‘clean’ version with a clear view, and an unclear one due to weather conditions. NTNU researchers hope that the SeaIceWeather dataset will be used by more people and that it inspires them to collect these types of images.
Many of the users are researchers who are working on sea ice and navigation models, or dynamic positioning. These systems must work in all weather conditions, and the more images the algorithms are given to learn from, the more accurate the monitoring, ice warnings, and navigation will become – something which is very much in demand.
An AI-based system for sea ice analysis helps the crew understand the ship’s surroundings. “We can use this information to develop advanced systems to avoid collisions, for safer navigation and the best sailing routes possible. The latter will also help reduce emissions,” says PhD candidate Nabil Panchi (Illustration: Nabil Panchi)
More ships – and inexperienced captains
Global warming is causing sea ice to melt, increasing the amount of Arctic shipping. More and more shipping companies are choosing these new routes that have now become ice-free. Between 2013 and 2019, ship traffic in the Arctic increased by 25 percent.
“It takes a lot of experience to navigate safely through sea ice. There are probably more ships in polar waters now than there are experienced sea ice captains. The system we have built can provide better assistance for people maneuvering the ships,” says Panchi.
Arctic sea ice has become thinner, cracks more easily, and can make massive ice ridges or hummocks. From the bridge of a ship, only one meter of ice might be visible sticking up above the surface, but not the 4-5 meters hidden below. The likelihood of dents and hull damage is high, and not all ships are built to break through ice.
An AI-based system for sea ice analysis helps the crew understand the ship’s surroundings. “We can use this information to develop advanced systems to avoid collisions, for safer navigation and the best sailing routes possible. The latter will also help reduce emissions,” says PhD candidate Nabil Panchi
At the same time, autonomous shipping holds the potential to revolutionize the shipping industry – making it more efficient and safer. According to Fortune Business Insights, the global autonomous ships market size is projected to grow from $6.11 billion in 2024 to $12.25 billion by 2032.
“We expect more autonomous technology on ships navigating through ice, and current systems need to be trustworthy in the extreme Arctic environment,” says Kim.
30 days of data capture
Panchi has trained the algorithms on two image datasets: one collected during the GoNorth voyage on Kronprins Haakon, the other obtained from online image databases.
He mounted two cameras on one side of the ship, with one camera directly under the other one. The upper camera had a clear view, while they had mounted a transparent screen in front of the lower camera, which was sprayed with water to simulate raindrops on the lens.
In the observation room on the ninth deck, Panchi’s computer continuously downloaded the images of sea ice. For 30 days, he collected thousands of pairs of images, each of which consisted of one clear image and one covered with artificial rain.
Training algorithms
In total, the datasets consist of over 4600 clear images, most of them from the research voyage. Using algorithms, they created seven weather variants for each clear image: small, medium and large snowflakes, rainy weather, fog, and real and simulated raindrops on the camera lens.
Based on these variants, they then created the two datasets. One of them presents images that indicate what kind of ice is located around the ship. The other dataset divides the ice into different categories, such as ice floes, pancake ice, ice slush, drift ice, etc.
Three different image-cleaning algorithms were trained on the datasets, and when the researchers compared the results with the clear images, they could easily tell which algorithms were most accurate in relation to the different types of weather.
Only daylight and three types of weather
The method is limited in that all the images are taken in broad daylight and involve only three types of weather conditions. Panchi points out that since the Arctic is in darkness from September to March, similar images should ideally be collected during the winter. However, it is also fully possible to use Augmented Reality (AR) and create an artificial winter or night-time version of the existing images.
“So far, it’s mainly researchers who can use what we have done, but we hope that more people will use it in the future. There are many factors affecting when this will actually happen; it may take up to 5 years before the models can be used commercially. They must then be of a quality that make them a fully reliable assistant for ship management,” Nabil said.
Reduced emissions
The largest ships use enormous amounts of fuel. They sometimes have to sail back and forth into the ice in order to break through, which requires a lot of energy.
“If you fully understand the conditions surrounding the boat, you or AI can plan the route and save time, effort and therefore emissions. It will also make shipping safer. There are a growing number of tankers carrying liquefied natural gas and other cargo sailing through the Arctic. So far, there haven’t been any oil spill incidents, but if one were to occur, it would have serious consequences,” says Panchi.
A lot of unused image data
Monitoring polar waters is also important with regard to climate change. Many ships have cameras and sensors that monitor their course. There are lots of ships producing images, but hardly any of these images are available online. According to Panchi, most of the images end up in maritime data archives, and – apart from a few insurance cases – are never used.
“We see great opportunities in extracting useful data from these images. One of our goals is to develop algorithms that can be improved in real time, on site. Improving how we monitor Arctic waters will benefit society. It will provide a better basis for forming policies, and for sustainable and safe use of Arctic waters,” Panchi said.
