Daewoo Shipbuilding & Marine Engineering (DSME) on Thursday (16 June), in a world’s first application, installed a high manganese steel liquefied natural gas (LNG) bunker fuel tank to an ultra-large crude oil carrier.

DSME and POSCO have jointly developed the tank manufacturing technology for 10 years, from pretreatment to welding to use high manganese steel to build an LNG fuel tank.

“And finally, after mass production and processability verification, it was mounted on a real ship this time, and we saw the fruits of 10 years of joint effort,” said DSME. 

“As a result, the two companies have established Korea's own unique LNG fuel tank ecosystem centred on high manganese steel, thereby securing national competitiveness in fire management (materials, parts, and equipment).”

Until now, materials such as Invar (nickel alloy steel), aluminium, and stainless steel have been used for cargo holds and fuel tanks that can withstand the cryogenic temperature of -163°C. 

However, they had disadvantages such as high price, difficult work process, and low strength. 

“The onboard high manganese steel LNG fuel tank overcomes these shortcomings. The newly applied high manganese steel has a lower price than existing materials, and has high strength and wear resistance as well as performance at cryogenic temperatures,” said the firm. 

Daewoo Shipbuilding & Marine Engineering President Park Doo-sun, who attended the ceremony to install the bunker tank on the carrier, said: “Our company, which boasts the world’s most competitive edge as a renowned LNG carrier, has set another milestone. As it is a technology, we will lead to strengthening the competitiveness of the entire Korean shipbuilding industry.”

Choi Jong-gyo, Executive Vice President of POSCO Research Institute, said, “The successful mass-production of high-manganese steel, a unique Korean material, to global LNG-powered ships is overwhelming. I believe that it will play a big role in the future eco-friendly ship market.”

The Maritime and Port Authority of Singapore (MPA) on Tuesday (11 February) conducted a table-top exercise (TTX) with Indonesia and Malaysia to enhance regional coordination and strengthen response capabilities for oil spills. The exercise brought together over 20 representatives from MPA, Indonesia’s Directorate General of Sea Transportation, Malaysia’s Environment Department, and oil spill response experts from ITOPF. As part of Singapore’s chairmanship of the Revolving Fund Committee (RFC) from April 2022 until March 2027, MPA led the TTX to foster collaboration between the littoral States of Indonesia, Malaysia and Singapore. The RFC, established through a memorandum of understanding (MOU) between the three littoral States and the Malacca Strait Council (MSC) in 1981, is a funding mechanism allowing each littoral State to draw cash advance from the Fund to combat oil spill from ships in the Straits of Malacca and Singapore (SOMS). The exercise focused on coordination procedures to ensure swift and clear communication between the littoral States during an oil spill incident, rapid deployment of oil spill response assets by the littoral States, and collaboration between government agencies and oil spill response companies to optimise oil spill response resources for incidents in the SOMS. The response strategies and asset deployment plans tested during the TTX will be exercised during a Ground Deployment Exercise between the three littoral States and ITOPF in 2026.

South Korea’s HJSC scores LNG bunkering vessel order from H-Line Shipping

South Korean HJSC scores LNG bunkering vessel order from H-Line Shipping

HJ Shipbuilding & Construction (HJSC) has secured its first order of the year with a contract worth KRW 127.1 billion (USD 87.6 million) to build an 18,000㎥ LNG bunkering vessel for H-Line Shipping. 

The contracted vessel is a large-scale LNG bunkering ship measuring 144 meters in length, 25.2 meters in width, and 12.8 meters in depth. It is capable of supplying up to 18,000㎥ of LNG in a single operation to LNG-fuelled ships. 

Equipped with two independent LNG tanks certified by the International Maritime Organization (IMO), the vessel features a dual-fuel propulsion system that allows it to operate on both eco-friendly LNG and marine diesel oil. This advanced system ensures both stability and operational efficiency while effectively reducing carbon emissions.

Yoo Sang-cheol, CEO of HJSC, said, “As global LNG demand and supply continue to grow, the LNG bunkering vessel market will see steady expansion.” 

“We will focus on strengthening our expertise in building eco-friendly, high-value-added ships, securing a competitive edge that aligns with our legacy as a leader in shipbuilding.”

This achievement follows the company's success in 2014 when it built the world’s first 5,100㎥ LNG bunkering vessel for Japan’s NYK Line.

“This accomplishment also reinforces South Korea’s shipbuilding industry's efforts to enhance competitiveness by securing high-efficiency, environmentally friendly vessels in the global market,” HJSC said. 

“Notably, with the anticipated expansion of oil and natural gas drilling and the resumption of LNG exports under the second Trump administration in the US, the market for crude oil carriers, LNG carriers, and LNG bunkering vessels is expected to see significant growth.”

“This trend is likely to benefit the country’s highly competitive shipbuilding industry.”

AMSOL tanker “Uhambo” commences offshore bunkering operations in Algoa Bay

Marine services provider AMSOL recently announced that its product tanker Uhambo has started offshore bunkering operations in Algoa Bay, signalling that the service has resumed in the maritime bay in South Africa.  

“Now flying the South African flag and an important platform for the ongoing training and development of tanker-endorsed South African seafarers, the Uhambo has commenced offshore bunkering operations in Algoa Bay, delivering locally refined marine fuel on behalf of its oil industry client,” the company said in a statement shared with Manifold Times

In November 2024, the South African Revenue Services (SARS) released new protocols including amendments under sections 21, 60, and 120 of the Customs and Excise Act. Some amendments pertain to the storage of imported bonded fuel goods in designated customs and excise storage warehouses.

SARS' move was anticipated to facilitate bunkering to resume off Algoa Bay, which has been shut down since September 2023

AMSOL’s Chief Commercial Officer Graham Dreyden, said: “Our ability to comply with stringent operating regulations and legislation as well as international maritime and marine standards underpins AMSOL’s track record.”

“This is the case for operations in Algoa Bay and we have worked closely with authorities and relevant stakeholders to ensure all legislative requirements for offshore bunkering operations are met.”

AMSOL’s CEO Dan Ngakane said he is positive about the growth of the company and its broader impact. 

“We have acquired five vessels in the last 4 years in order to meet the needs of our clients in the region for reliable and professional, risk managed marine solutions,” he said.

“In leading growth in the South African maritime sector, we remain committed to meeting the highest standards for environmental protection, safety and compliance whilst developing the talent required to keep our industry growing and moving forward.”

AMSOL said it is the only marine services business operating in the region with a proven track record in effective management of risk-mitigated fuel transfers through a portfolio of services that include in-port bunker delivery, offshore bunkering, ship-to-ship fuel transfer services and offshore terminal management.
