Lloyd’s Register Fuel Oil Bunkering Analysis and Advisory Service (FOBAS) on Wednesday (26 October) released a bulletin highlighting International Council on Combustion Engines (CIMAC ) working group’s recent paper summarising the situation around the organic chloride contamination cases earlier this year in Singapore and updates on the cases:

We would like to highlight the recently released update and informative paper from CIMAC Working Group on marine Fuels. The original document from CIMAC can be downloaded here. Lloyd's Register FOBAS has a strong presence in the CIMAC working group and our aim is to represent our clients’ interests in all areas we possibly can. The document provides a summary of the situation around the organic chloride contamination cases earlier this year in Singapore and follows on from updates and case summary released previously by MPA in Singapore.

Back in late February/early March, we had reports from one or two vessels of problems including fuel pump damage while using high sulphur fuels bunkered from Singapore. After detailed investigation, it was discovered that organic chlorides or COC’s (Chlorinated Organic Compounds) were present in the fuel at very high concentrations. Once it was clear this was not just a one-off incident, we issued an alert to all our clients on 29th March, with a further update on 14th April as well as directly contacting many vessels who, based on their bunkering information, were deemed most at risk of having been supplied with contaminated fuel. Although many vessels did face problems, we were able to preemptively warn many more to then have time to test their fuels before being put into use or de-bunkered.

It has been our stance from past experiences that organic chlorides should not be present in any marine fuel and that under certain conditions can cause corrosive damage to system components including fuel pumps. As described in the CIMAC statement, there is a clear cause and effect link that can be drawn and clear understanding that they should not be present.

As a solution provider to our client base, we offer specific testing to determine the presence and concentration of organic chlorides, however this should ideally be controlled on the supplier’s side, and we do see this as a rare incident that hopefully can be avoided in the future. There is also ongoing work in the industry to standardise the ASTM D7845 organic chloride test method to determine the specific organic species, which we have already applied successfully; recognising that the supplier’s responsibility to meet the limit has been set against the test method for Total Organic Chlorine EN 14077 as highlighted in the CIMAC paper. As ever we will be monitoring fuel quality and alert vessels to any signs of similar incidents in the future.

The Maritime and Port Authority of Singapore (MPA) on Friday (1 November) issued Port Marine Circular No. 12 of 2024 informing the marine industry that the use of SS 648: 2024 for the custody transfer of bunker deliveries to ocean-going ships in the Port of Singapore will be mandatory from 1 April 2025:

This circular serves to inform the maritime industry that the Maritime and Port Authority of Singapore (MPA) will mandate the use of SS 648: 2024 for the custody transfer of bunker deliveries to ocean-going ships in the Port of Singapore from 1 April 2025. Consequently, the use of SS 648: 2019 will cease from 1 April 2025. 

Published by the Singapore Standards Council in October 2024, the SS 648: 2024 serves as the latest version of the SS 648 and is the result of a joint review of the previous version (SS648: 2019) by the MPA, Singapore Shipping Association (SSA), International Bunker Industry Association (IBIA), as well as representatives from bunker suppliers/craft operators, bunker buyers, testing and surveying companies, oil majors, equipment vendors, relevant government agencies and industry experts to meet the changing needs of the bunkering industry. 

The SS 648: 2024 is divided into 2 parts for ease of operational use. Part 1 covers pre-approval processes such as meter selection, acceptance tests, etc.; while Part 2 covers post-approval processes such as health, safety and environment requirements, metrological requirements, system integrity requirements and metering procedures. Other key changes include:  

  • Updating of the acceptance test to include single tanker meter-in meter-out as an additional option for approval of Mass Flow Metering (MFM) system;
  • Considerations after a software update or upgrade to provide better clarity;
  • Biofuels in the coverage of the standard;
  • Use of data logger and edge device with enhanced requirements for data security, data integrity and data transmission requirements;
  • Replacing minimum measured quantity (MMQ) with new table on minimum bunker quantity (MBQ) for better clarity;
  • Updates of the sampling requirements with new information from SS 600:2022 Code of practice for bunkering by bunker tankers using tank gauging;
  • New content on digital documentation to be cross referenced to new Specification for Digital Bunkering Supply Chain Documentation; and
  • Reorganisation of the content of bunker claims procedures and dispute resolution

Training Requirements for Cargo Officers and Bunker Surveyors 

The MPA has worked with SSA and IBIA to develop a refresher course on the new requirements of the SS 648: 2024, which is expected to commence from January 2025. All in-service bunker cargo officers and bunker surveyors are required to complete this refresher course (conducted by SSA and IBIA) by 1 April 2025. Bunker cargo officers and bunker surveyors that have not attained the necessary certification will not be allowed to conduct bunkering operations in the Port of Singapore.

South Korea achieves milestone with first SIMOPS methanol bunkering in Busan

South Korea successfully conducted its first ever Simultaneous Operations (SIMOPs) of ship-to-ship methanol bunkering at Busan New Port on 4 October, according to Korean Register (KR) on Thursday (30 October). 

KR said this groundbreaking achievement marks a crucial advancement in the nation's commitment to developing a sustainable ship fuel supply chain.

In an 11-hour bunkering operation, Hyodong Shipping’s bunkering vessel Hyodong Chemi supplied 3,000 metric tonnes (mt) of methanol to containership Antonia Maersk at Busan New Port Terminal 2(PNC) during cargo unloading. 

This follows the successful LNG bunkering SIMOPs at Busan New Port in August. 

The Ministry of Oceans and Fisheries (MOF) spearheaded this initiative as part of its plan to build an Eco-friendly Ship Fuel Supply Chain, announced in November 2023. The ministry has been diligently working on securing bunkering vessels, developing port infrastructure, and standardising bunkering procedures.

Busan Port Authority (BPA) supported the methanol bunkering demonstration project, offering exemptions on port facility usage fees and coordinating with relevant agencies to review safety protocols through an inter-agency consultative body.

Korean Register (KR) has played a pivotal role in providing technical support for the development of a methanol bunkering safety system. KR's contributions include developing standard operating procedures, defining safety management zones, and creating guidance for self-safety management plans.

This accomplishment is expected to significantly enhance the competitiveness of South Korean ports in the growing market for eco-friendly shipping. The successful implementation of SIMOPs, which allows for simultaneous cargo operations and supply of green fuel, is particularly attractive to shipping companies aiming to reduce costs and improve efficiency.  

KANG Joonsuk, CEO & President of BPA, said: “This successful demonstration marks a monumental achievement, showing that Busan Port is fully capable of supplying methanol. We plan to enhance Busan Port’s global competitiveness by developing infrastructure and advancing technology to expand eco-friendly fuel bunkering, positioning it as a leading green port on the world stage.”  

LEE Hyungchul, Chairman & CEO of KR, said: “As the maritime industry continues to seek greener alternatives, South Korea is trying to position itself at the forefront of sustainable shipping practices. KR will continue to provide full support for technical cooperation to ensure safe and successful green fuel bunkering operations.”

HD Hyundai Heavy Industries wins DNV AiP for ammonia DF large container vessel

Classification society DNV on Wednesday (30 November) said it has awarded an Approval in Principle (AiP) to HD Hyundai Heavy Industries (HD HHI) for its 15K TEU ammonia dual-fuelled container vessel design. 

DNV said the milestone follows the successful completion of a joint development project aimed at addressing the challenges associated with using ammonia as a marine fuel.

“The project focused on developing designs to enhance safety, including an optimised ammonia tank design, advanced fire safety systems, enhanced ammonia release mitigation system and boil-off gas (BOG) handling systems,” it said in a statement. 

“These innovations could play an important role in building confidence in the safe and efficient use of ammonia as a marine fuel.”

On container ships, where the upper deck is a safe working zone, DNV said an ammonia leak could pose a serious risk. This means, establishing safety design criteria to manage these risks is crucial for the wider commercialization of ammonia-fueled ships.

To this end, fuel pipe leakage scenarios were defined and quantitatively analysed through gas dispersion analyses. Consequently, it was confirmed that, with conventional systems, foreseeable small leakages occurring at connections within the ammonia piping system can form toxic areas with dangerous ammonia concentrations throughout the entire weather deck, highlighting the need for effective mitigation measures. 

The result showed that hazardous areas were significantly reduced by the enhanced ammonia release mitigation system, enabling not only safer enclosed spaces but also safer working areas across the entire weather deck of the vessel.

Seung-ho Jeon, SEVP, CTO of HD HHI, said: “The AiP reflects HD HHI’s dedication to developing sustainable, innovative solutions like ammonia-fuelled vessels, which will play a key role in reducing emissions and shaping the future of shipping.”

Vidar Dolonen, DNV Regional Manager Korea and Japan, said: "This AiP highlights the importance of safety in moving the maritime industry along the path to decarbonization.”

“There are many aspects to building out zero carbon fuels in shipping, and it’s essential that we have them all in place for ammonia to truly establish itself in the marine fuel market.”

“But with new technological solutions, alongside rigorous safety procedures, ammonia reach its full potential as one of the most promising green fuels. DNV is proud to support these advancements from HD HHI as we continue on this journey to an even more sustainable maritime industry.”
