Daewoo Shipbuilding & Marine Engineering (DSME) on Friday (14 October), in a world’s first application, installed a high manganese steel liquefied natural gas (LNG) bunker fuel tank to two dual-fuel very large crude carriers (VLCCs). 

DSME also announced that it held a simultaneous naming ceremony on 13 October for both VLCCs. 

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.

“Through this, Korea’s unique LNG fuel tank ecosystem, centered on high manganese steel, was established to secure national competitiveness,” the firm said.

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

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

“The high manganese steel LNG fuel tank overcomes all these shortcomings. High manganese steel, a new material, is attracting attention as a next-generation material for LNG cargo holds because its price is lower than that of existing materials, and it has high strength and abrasion resistance as well as performance at cryogenic temperatures,” the company elaborated. 

Daewoo Shipbuilding & Marine Engineering President Park Doo-seon, who attended the naming ceremony, said: “We have proven once again the competitiveness of DSME’s eco-friendly shipbuilding technology by building the world’s first dual-fuel VLCC equipped with an LNG fuel tank made of high manganese steel.” 

“We will do our best to secure overwhelming technology through development.” 

Manifold Times previously reported DSME installed a high manganese steel LNG bunker fuel tank to an ultra-large crude oil carrier.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
