UK Warns of “Yemeni Authorities” Contacting Vessels in the Red Sea

Yemen
UKMTO issued an alert about calls for supposed "Yemeni authorities" (UKMTO)

PUBLISHED DEC 8, 2023 8:13 PM BY THE MARITIME EXECUTIVE

 

 

Unidentified individuals claiming to the “Yemeni authorities” appear to be attempting to commander vessels sailing in the southern Red Sea area by issuing commands over the radio. While the efforts have not been backed by any direct assault on the ships, warnings are being repeated for vessels to exercise caution while the U.S. authorities have now directly associated the attacks with the regime in Iran.

The UK Maritime Trade Organization (UKMTO) which coordinates between the Royal Navy and the commercial shipping industry, issued a new safety alert on Friday, December 8, warning of new efforts by unknown individuals in Yemen. They are advising caution while requesting reports on any suspicious activity in the region.

According to the alert, the latest incident took place late on December 7 when an unidentified vessel sailing in the southern Red Sea near the port of Hodeidah in Houthi-controlled regions of Yemen was contacted. Individuals declaring to be the “Yemeni authorities” reportedly ordered a vessel to “alter course.” The vessel appears to have ignored the command and proceeded without further incident, but the UK authorities are warning of this tactic.

It is not the first time this has been reported and so far, there has been no follow-up to the radioed commands. After the three merchant vessels were attacked on Sunday, December 3, there were reports that one of the vessels received a similar contact also ordering the vessel to alter course. The reports said in that instance the vessel claimed to have been dealing with damage from the attack and unable to change course. The owners of the ships that came under attack later issued statements saying that their vessels had not suffered significant damage and had been able to continue on their voyages.

 

 

U.S. authorities however did report further drone sightings including a downing of another drone that was approaching the area near a U.S. destroyer. Officials said the captain of the USS Mason decided to down the drone because of its position, but it was unclear if the drone was attempting to target the warship.

S&P Global reported today that two shipping companies, Zodiac Maritime and Eastern Pacific Shipping, both with Israeli owners, have however decided to divert their vessels. Neither company responded to S&P’s requests for information, but they believe that the companies are rerouting gas carriers away from the Red Sea.

All of this came as Reuters was reporting that United States officials had publicly stated that Iran is involved in the planning and execution of drone and missile attacks by the Houthi rebels. Security advisers to President Joe Biden would not rule out direct U.S. actions against the Houthis if the attacks on civilian shipping continued.

“The Houthis continue to receive funding and support from Iran, and the result is unsurprising: unprovoked attacks on civilian infrastructure and commercial shipping, disrupting maritime security and threatening international commercial trade,” said U.S. Under Secretary of the Treasury for Terrorism and Financial Intelligence Brian Nelson. 

On Thursday, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) used counterterrorism regulations to sanction 13 individuals and entities that the U.S. said were responsible for providing tens of millions of dollars of foreign currency to the Houthis in Yemen. They accused the individuals of using a complex network of exchange houses to sell Iranian commodities and funnel money to the rebels. The U.S. vowed to continue to disrupt the financial activities that “enable these destabilizing activities.”

Discussions are also reported to be continuing about expanding the current multinational task force operating in the Persian Gulf region and the Indian Ocean to encompass more areas including the Red Sea. There are also reports that convoys have been discussed as a means of providing greater security to commercial vessels sailing in the Red Sea and transiting the Bab El Mandeb Strait off the coast of Yemen.

On Saturday night, a French warship shot down two drones over the Red Sea, adding to a growing list of encounters between Western warships and UAVs launched from Yemen. 

In a statement, the French general staff reported that the frigate Languedoc identified and destroyed "two identified threats" that were "headed straight towards her." The intercepts occured several hours apart, first at 2300 hours local time and then again at 0130 hours Sunday. 

The encounter occurred about 60 nm off the coast of Hodeidah, Yemen, far from any shore. Yemen's Houthi rebel faction is known to possess Iranian-built Samad, Shahed and Ababil suicide drones, which have more than adequate range to reach across the Red Sea. These are relatively low-tech, inexpensive devices: the estimated price of a Shahed-136 is in the range of $20,000.   

A video released by the U.S. Navy on Saturday shows that the drone shootdowns are an expensive endeavor. The video, produced by the crew of the destroyer USS Carney, shows the ship launching multiple SM-2 or Evolved Sea Sparrow missiles from its VLS cell launchers. Depending on purchase batch and missile type, these rounds are priced at about $1.0-2.1 million, about 50-100 times the price of a Shahed-136.

The White House has said that it wants to form a new coalition of international partners to assure maritime security in the region. The new group would draw on the membership of the American-led Combined Maritime Forces coalition, and White House National Security Council spokesman John Kirby said last week there have been conversations with "several key partners that are interested in coming aboard." It would be the third international maritime security partnership for the Red Sea and Gulf of Aden, in addition to the EU-led EUNAVFOR Operation Atalanta and the CMF's existing CTF-153. 

The U.S. Treasury has also announced sanctions on a network of Iranian-backed money launderers who have funneled funds to the Houthi movement. However, the White House has stopped short of re-designating the Houthi faction as a terrorist organization. The Houthi rebels were on the terrorist list until February 2021, when the Biden administration removed them. 

In a statement Saturday, a Houthi spokesperson warned that all Israel-bound ships may be subject to attacks. 

“If Gaza does not receive the food and medicines it needs, all ships in the Red Sea bound for Israeli ports, regardless of their nationality, will become a target for our armed forces,”

The Houthi group continues to hold the car carrier Galaxy Leader and its crewmembers as hostages near the port of Al Salif. Videos produced by Yemeni influencers suggest that the ship has become a tourist attraction, and even young children have been ferried out to visit the seized vessel.


 

Chinese Coast Guard Cutter Hits Philippine Supply Boat in S. China Sea

Contact
China Coast Guard cutter makes contact with a Philippine supply boat (PCG)

PUBLISHED DEC 10, 2023 8:34 PM BY THE MARITIME EXECUTIVE

 

 

On Sunday, a China Coast Guard cutter "rammed" a Philippine supply boat as it attempted to make the transit to Second Thomas Shoal, where the Philippine military maintains a small outpost. The supply boat was unharmed and reached the garrison aboard a decaying WWII landing ship, the BRP Sierra Madre. The interaction - along with other serious damage caused by Chinese vessels over the weekend - suggests that China has a  new willingness to escalate in its recurring confrontations. 

According to PCG spokesman Commodore Jay Tarriela, the cutters BRP Cabra and BRP Sindangan attempted to escort a supply convoy of two wooden boats to the shoal, as they have many times before. The convoy encountered resistance from the China Coast Guard, as expected. 

Tarriela reports that Chinese cutter CCG 5204 - a familiar presence - used its water cannon in an attempt to deter the supply boat Kalavaan. The high-pressure water cannon caused "severe damage to Kalavaan's engines," said Tarriela, disabling the vessel. The cutter BRP Sindangan took Kalavaan in tow and returned to the shelter of Ulugan Bay, Palawan. 

Meanwhile, the smaller Chinese cutter CCG 21556 pursued the supply boat Unaizah Mae 1. During a close-quarters interaction, 21556 "rammed" the Unaizah, according to Tarriela. A Philippine video of the scene appears to show that the cutter's reinforced port bow made contact with the Unaizah's starboard quarter, nudging Unaizah

However, the China Coast Guard suggested that Unaizah Mae 1 struck the CCG 21556's bow with her stern, and provided a different video that appears to show Unaizah turning to port in the moments before contact.  

The collision bore some similarity to a previous interaction at Second Thomas Shoal in October, when CCG 5203 made light contact with the Unaizah May 2's starboard quarter. 

The resupply runs to Second Thomas Shoal typically involve tense standoffs between the China Coast Guard and the Philippine Coast Guard. China claims ownership of the Spratly Islands and surrounding waters, including areas within the Philippine exclusive economic zone, like Second Thomas Shoal. Beijing has repeatedly ordered Manila to withdraw from the BRP Sierra Madre, but Philippine forces have held out, thanks to high-risk missions like Sunday's. 

In previous confrontations, Chinese forces have used aggressive maneuvering, water cannons, acoustic devices (LRAD) and laser target illuminators to deter Philippine supply boats. The PCG has long warned that these tactics increase the risk of collision.

Tarriela noted that Second Thomas Shoal is a low-tide elevation, not a habitable island capable of supporting a sovereignty claim, and he emphasized that it lies within the Philippine Exclusive Economic Zone. In 2016, the Permanent Court of Arbitration in the Hague dismissed Chinese assertions of sovereignty over Philippine waters.

"The systematic and consistent manner in which the People's Republic of China carries out these illegal and irresponsible actions puts into question and significant doubt the sincerity of its calls for peaceful dialogue. Peace and stability cannot be achieved without due regard for the legitimate, well-established, and legally settled rights of others," said Tarriela. 

Multiple encounters

Sunday's run-in at Second Thomas Shoal was just one of three menacing encounters between Philippine vessels and Chinese "gray zone" forces over the weekend. 

On Saturday, during a mission to support Philippine fishermen at disputed Scarborough Shoal, civilian boats from the Philippines’ Bureau of Fisheries and Aquatic Resources ran into opposition from the China Coast Guard. CCG cutters used water cannons and Long Range Acoustic Devices (LRADs, also known as sound cannons) on three of the bureau's boats. The LRADs performed as designed, incapacitating some crewmembers and causing others temporary discomfort. The CCG also deployed small boat crews and strung a new floating barrier across the entrance to the shoal. 

"The aggression and provocations perpetrated by the China Coast Guard and their Chinese Maritime Militia against our vessels and personnel over the weekend have only further steeled our determination to defend and protect our nation's sovereignty," said Philippine President Ferdinand Marcos Jr. in a statement. "Bajo de Masinloc [Scarborough Shoal] is sovereign Philippine territory and an integral part of our archipelago. No one but the Philippines has a legitimate right or legal basis to operate anywhere in the West Philippine Sea. The illegal presence in our waters and dangerous actions against our citizens is an outright and blatant violation of international law and the rules-based international order."

Meanwhile, a civilian "humanitarian" convoy operated by activist group Atin Ito ("This Is Ours") had also planned to visit Philippine outposts in the Spratly Islands in order to deliver Christmas gifts and supplies. The Philippine government had attempted to discourage the civilian convoy for months, citing the risk that its citizens might run in encounters with Chinese forces. On Sunday, after "constant shadowing of four Chinese vessels" - including two PLA Navy warships - the Atin Ito convoy decided to turn around and head back to Palawan. The decision was taken in consultation with the Philippine Coast Guard, organizers said. 

 

COVID-19 pandemic study shows adherence to infection precaution measures among healthcare personnel varies by job role


Researchers recommend changes to training and strategy to better protect healthcare workers in the future


Peer-Reviewed Publication

ASSOCIATION FOR PROFESSIONALS IN INFECTION CONTROL





Arlington, Va. — December 7, 2023 — A new study published today in the American Journal of Infection Control (AJIC), based on a survey of healthcare professionals conducted during the height of the COVID-19 pandemic, suggests that new efforts may be needed to strengthen infection prevention precautions and protect staff members at the highest risk of exposure to dangerous pathogens. This is believed to be the first study of pandemic-era infection precautions to include a broad variety of healthcare jobs. Researchers found that workers who had the highest risk of exposure to SARS-CoV-2 were also the most likely to report errors in their own adherence to infection prevention measures.

 

Many infection prevention studies have been performed to understand how healthcare professionals’ compliance with precaution guidelines held up during the COVID-19 pandemic, but until now most of those studies have focused on physicians and nurses. This new study expands on that body of research by including other members of the healthcare profession who experienced exposure risk, including respiratory, physical, and speech therapists; food services; environmental services; and clinical dieticians. Typical infection prevention and control measures include practices such as hand hygiene and the use of personal protective equipment (PPE) such as masks, gloves, and gowns.

For this study, researchers analyzed responses to surveys from 191 healthcare personnel at the University of North Carolina Medical Center. Participants were enrolled between July 2020 and January 2021 and were asked to report their experiences in SARS-CoV-2 exposure and adherence or non-adherence to infection precaution protocols. Respondents were grouped into three broad categories: physicians, advanced practice providers, physician assistants, and nurse practitioners (45%); registered nurses (27%); and other, which included therapists, dieticians, and members of food and environmental services (28%). In addition to the self-reported survey data, study researchers also routinely observed healthcare staff and monitored their compliance with infection precautions to collect validation data. Generally, the trends reported in survey responses and by the observers was concordant.

Data analysis showed statistically significant differences between job role, risk of potential exposure to SARS-CoV-2, and likelihood of making errors in infection precaution adherence. For example, 57.4% of registered nurses completed job tasks that placed them at a higher risk of SARS-CoV-2 exposure, compared to nearly 29% of physicians and 38% of the “other” category. Healthcare personnel who were more likely to be exposed to the virus were also 5.74 times more likely to report at least one error in infection precautions in the previous 2 weeks, such as failure to don protective gear.

“While error rates varied by job type, what this study really shows is that all three groups of healthcare personnel were at risk of SARS-CoV-2 exposure and were making errors in adherence to infection prevention protocols during the height of the pandemic,” said Emily J. Haas, PhD, a research health scientist at the Centers for Disease Control and Prevention’s National Institute for Occupational Safety and Health and National Personal Protective Technology Laboratory, and lead author of the study. “This is a clear demonstration that we need to improve engagement in our training for emergency preparedness and to create a more strategic response that will help our healthcare workers stay safe even in times of extreme stress.”

In this study, researchers also found that:

  • Adherence to PPE guidelines varied by job type: more registered nurses (33.3%) and physicians (26.5%) reported at least one error in the previous two weeks than those in the “other” category (9.6%).
  • Respondents reported reliable access to PPE, with most saying they always had access to gowns (93%), gloves (99%), eye shields (98%), and face masks (98%).
  • Hand hygiene was the infection precaution most frequently performed incorrectly, with study observers noting that hand and glove hygiene protocols were only adhered to 40% of the time between visits to rooms with patients who had COVID-19.

“This study adds to our understanding of healthcare personnel compliance with infection prevention protocols during COVID-19 and highlights improvement opportunities,” said Patricia Jackson, RN, BSN, MA, CIC, FAPIC, 2023 APIC president. “Infection preventionists can use this information in their education and outreach to strengthen preparedness for future outbreaks and to improve the safety of the day-to-day delivery of healthcare.”

There has been a surge in academic and business interest in software as a medical device (SaMD). It enables medical professionals to streamline existing medical practices and make innovative medical processes such as digital therapeutics a reality. Furthermore, SaMD is a billion-dollar market. However, it is not clearly understood as a technological change and emerging industry. This enlightened researchers from Tokyo Institute of Technology to a new study. They reviewed FDA-approved SaMDs to shed light on the market landscape, the role of SaMDs, and the innovation within the industry. Their findings highlight the industry's diversity and potential for growth and advocate improving healthcare-related data access.

Software as a Medical Device (SaMD) is an emerging field aimed at assisting medical professionals in diagnosing, monitoring, treating, or preventing diseases. The International Medical Device Regulators Forum defines SaMD as software intended for medical purposes, but not part of a hardware medical device. This refers to a wide range of software such as health apps on smartphones or wearable devices that monitor and track health, as well as complex medical imaging software for X-rays, MRIs, and CT scans. However, the SaMD industry is still in its nascent stages of development and requires clarity on innovation, the market landscape, and the regulatory environment.

To address the limitations associated with current SaMD research, researchers from Tokyo Institute of Technology (Tokyo Tech) and the University of Tokyo recently conducted a comprehensive review of various aspects of SaMDs over the past decade, utilizing data from the U.S. Food and Drug Administration (FDA), the authoritative body for approving commercially marketed medical devices in the United States. Professor Shintaro Sengoku, Jiajie Zhang, and Jiakan Yu, the authors of the study published in the Journal of Medical Internet Research, state: “The objectives of our work are to clarify the innovation process of SaMD, identify the prevailing typology of such innovation, and elucidate the underlying mechanisms driving the SaMD innovation process.”

The researchers collected information on FDA-approved SaMDs from the OpenFDA website. They also gathered profiles of 268 companies associated with these devices from various sources, including Crunchbase, Bloomberg, PichBook.com, and SaMD company websites. To be considered a SaMD, a device had to function as standalone software fulfilling medical functions. Devices operating solely as part of hardware or requiring additional hardware were excluded from the review.

The findings reveal significant growth in the SaMD industry. Between 2012 and 2021, the number of FDA-approved SaMDs increased from one to 581. Most SaMDs were developed for medical image processing and radiological analysis (78%), followed by cardiology, neurology, ophthalmology, and dentistry. The researchers also identified notable progress in artificial intelligence/machine learning based SaMDs, accounting for 22% of all FDA-approved SaMDs, marking what researchers are calling the 'third AI boom' in healthcare.

The United States leads in SaMD approvals (262 devices, 45%), followed by Germany, South Korea, and the Netherlands. Established companies in the medical device industry such as Siemens, General Electric, and Philips launched the most SaMDs (237 devices, 40.8%). These companies focus on incremental innovations to improve existing medical processes, such as image resolution or reducing manpower requirements for medical image processing.

New entrants or start-ups that were formed after 2012 accounted for about 37% (215 devices) of the launches. These small and micro companies focus on disruptive innovation which enables new medical practices, such as digital therapeutics and remote monitoring. Another notable player is the pharmaceutical industry, which is actively engaged in the digitalization process of healthcare, with significant investments in SaMD initiatives.

The study highlights the diversity and emerging nature of SaMD, its potential for growth, and its transformative impact on healthcare services. The findings emphasize that accelerated growth in this sector is closely linked to data accessibility in driving disruptive innovation within the industry. New entrants focusing on disruptive innovations will need to build their datasets or access existing data within the healthcare system.

“Governments and academic institutions should facilitate data accessibility as a public good to accelerate innovation in SaMD,” conclude the three authors, outlining recommendations for future developments in the industry.

This study was funded by the Japan Science and Technology Agency, Program on open innovation platform for industry-academia co-creation (COI-NEXT), "Center of health longevity and nursing innovation with global ecosystem" (Grant No. JPMJPF2202).

SYDNEY, Dec. 7, 2023 – Song mashups are a staple of many DJs, who mix the vocals and instrumentals from two or more tracks into a seamless blend, creating a new and exciting final product. While the result is fun to listen to, the creation process can often be challenging, requiring knowledge and expertise to select the right tracks and mash them together perfectly.

Xinyang Wu from the Hong Kong University of Science and Technology took a different approach, designing a computer algorithm to intelligently create mashups using the drum tracks from one song and the vocals and instrumentals from another. He will present his work Dec. 7 at 4:20 p.m. Australian Eastern Daylight Time, as part of Acoustics 2023, running Dec. 4-8 at the International Convention Centre Sydney.

While some algorithms and automated software can attempt to create song mashups, their results are often clunky and unrefined. These methods layer the complete, unaltered tracks on top of each other, aligning them based on detected key moments in the music, rather than skillfully combining the vocals and instrumentals of different songs.

“Imagine trying to make a gourmet meal with only a microwave – that’s sort of what automated mashup software is up against compared to a pro chef, or in this case, a professional music composer,” said Wu. “These pros can get their hands on the original ingredients of a song – the separate vocals, drums, and instruments, known as stems – which lets them mix and match with precision.”

His algorithm takes a different approach, mimicking the process used by professionals. The software works to isolate the stems from each song and identify the most dynamic moments. It adjusts the tempo of the instrumental tracks and adds the drum beat mashup at exactly the right moment for maximum effect.

The result is a unique blend of pleasing lyrics and exciting instrumentals with wide-ranging appeal.

“From what I’ve observed, there’s a clear trend in what listeners prefer in mashups,” said Wu. “Hip-hop drumbeats are the crowd favorite – people seem to really enjoy the groove and rhythm that these beats bring to a mashup.”

Now that the software has been tested on drum tracks, the team plans to tackle bass mashups next. For Wu, the dream is to expand the algorithm to incorporate the full instrumental suite and put user-friendly mashup technology directly into the hands of listeners.

“Our ultimate goal is creating an app where users can pick any two songs and choose how to mash them up – whether it’s switching out the drums, bass, instrumentals, or everything together with the other song’s vocals,” said Wu.

The Department of Energy’s Oak Ridge National Laboratory and Caterpillar Inc. have entered into a cooperative research and development agreement, or CRADA, to investigate using methanol as an alternative fuel source for four-stroke internal combustion marine engines. The collaboration supports efforts to decarbonize the marine industry, a hard-to-electrify transportation sector.

As the United States continues to seek ways to reduce environmentally harmful greenhouse gas, or GHG emissions, methanol is an attractive fuel alternative to diesel because it reduces carbon emissions. Methanol also reduces emissions of nitrogen oxides and sulfur oxides. In addition, methanol’s relatively high energy density makes it easier to store on marine vessels than gaseous fuels meaning it can be more easily integrated into overall existing engine design and operation.

Although methanol has many advantages, it is more difficult to ignite than diesel. Under the terms of the CRADA, ORNL researchers will work with Caterpillar over the next few years to identify, develop and test hardware configurations and operating strategies required to maximize use of methanol in engines retrofitted for methanol.

Research will be conducted on Caterpillar’s in-line 6-cylinder marine engine that has been modified for methanol use and installed at DOE’s National Transportation Research Center at ORNL. New engine designs will also be considered, and several engine combustion strategies will be explored including dual-fuel, dimethyl ether reforming and spark-ignited prechambers. Caterpillar will support ORNL by providing additional materials and research expertise to enable engine performance, efficiency and durability while reducing GHG and other emissions.

“We look forward to working with Caterpillar to develop near-term combustion strategies that can be retrofitted on existing engines to realize immediate reductions in carbon emissions. We also will develop long-term combustion strategies for new engine technologies that achieve 100% displacement of diesel fuel with methanol,” said ORNL’s Jim Szybist, section head for Propulsion Science. “The research we conduct over the next few years will be a significant contributor to decarbonization efforts globally.”

The project supports DOE’s Vehicle Technologies Office’s focus on reducing GHG emissions from off-road vehicles such as railway, aviation and heavy transportation vehicles used in agriculture, construction, mining and marine vessels. These sectors are significantly more challenging to decarbonize than on-road, light-duty transportation applications and require unique solutions.

“Caterpillar is proud to be working with ORNL as we develop the technology for a lower carbon future. Our marine customers across the U.S. have been clear that methanol will play a key role in their journey to net-zero emissions. The maritime industry has unique challenges that can’t necessarily be met by technologies being developed for other transportation sectors, so it is important to have this collaboration with ORNL to accelerate the technology and set the path for the future,” said Brad Johnson, vice president of Caterpillar Marine.

In addition to DOE’s Vehicle Technologies Office, the collaboration is funded by the U.S. Department of Transportation Maritime Administration.

UT-Battelle manages ORNL for the Department of Energy’s Office of Science, the single largest supporter of basic research in the physical sciences in the United States. The Office of Science is working to address some of the most pressing challenges of our time. For more information, please visit energy.gov/science.

A collaboration between Oak Ridge National Laboratory and Caterpillar Inc. will investigate using methanol as an alternative fuel source for marine vessels.
