Classification society DNV on Tuesday (25 January) shared the findings of a joint industry project (JIP) with TotalEnergies, Samsung Heavy Industries and a major Asian energy transport company.

The JIP investigated the rationale of ammonia as a future bunker fuel for a new liquefied natural gas (LNG) dual-fuel VLCC tanker design and the business cases for converting the vessel to ammonia while comparing it to other alternatives.

It analysed a very large crude carrier (VLCC) design assumed to be operating on a Middle East to Far East Asia route at a speed of 13 knots. The ship was assumed to begin operating in 2024 with a 20-year lifespan.

The study found design arrangements for an ammonia-ready newbuild must account for both LNG and ammonia.

For example, ammonia requires larger tanks to achieve the same level of autonomy – which has implications for the superstructure – and a stronger support structure underneath.

Other design properties, such as tank and piping materials, should be chosen with a potential retrofit for ammonia in mind.

Further, it noted the bunkering strategy of the vessel must be reassessed as the energy density of ammonia is considerably lower than that of LNG, almost half in terms of volume.

In summary, the research concluded additional costs to enable the VLCC to run on LNG (rather than conventional fuel oil) were about USD 20 million.

On top of this, an additional estimated USD 2 million was needed at the newbuilding stage to make the vessel ready for a future retrofit to ammonia.

In the study, the most cost-effective compliance strategy in all cases was to operate on LNG with increasing amounts of bio-LNG blended in.

“There is a way towards 2050, but the ‘right’ direction is very ship- and trade-specific, and a range of assumptions need to be established,” it concludes.

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.
