HD KSOE receives LR AiP for ammonia fuel supply system

Classification society Lloyd’s Register (LR) has granted Approval in Principle (AiP) to HD Korea Shipbuilding & Offshore Engineering (HD KSOE) for their ammonia fuel supply system, which will be used on ammonia new constructions.

The newly developed ammonia fuel supply system shows complete compatibility with high-efficiency cargo handling systems and ammonia engines.

The approval certifies the fuel supply system against LR’s rigorous risk-based certification (RBC-1) process and marks the successful conclusion of a Joint Development Project (JDP) between LR and HD KSOE, which began in April 2024.

The primary objective of the JDP was to develop and refine the design concept of an ammonia fuel supply system for ammonia-fuelled vessels.

LR said the AiP represents the substantial step that LR and HD KSOE have taken towards pioneering innovative solutions for emission reduction in the maritime industry.

“Ammonia, with its capacity to meet the rising demand for emission reduction solutions, represents a promising alternative fuel for the maritime industry,” it said.

“This fuel supply system addresses the pressing need for sustainable fuel solutions, significantly contributing to efforts aimed at reducing greenhouse gas emissions from the global fleet.”

Young-Doo Kim, Global Technical Support Office Representative for Korea, Lloyd’s Register, said: “This approval in principle represents another significant step for developing the technology required for shipowners and operators’ adoption of ammonia, one of the primary candidate fuels for the maritime energy transition.”

“We are pleased to continue our strong working relationship with HD KSOE through this joint project that will provide a valuable solution for ammonia propelled ships.”

Young-jun Nam, Vice Present & COO of HD KSOE, said: “Ammonia is a zero-carbon fuel that is attracting great attention in terms of economics and supply stability. HD Korea Shipbuilding & Offshore Engineering will lead the field of eco-friendly equipment and materials to take the lead in commercialising ammonia in 2025.”

SEA-LNG: LNG pathway offers best returns under IMO Net-Zero Framework

SEA LNG’s calculations show that under the Net-Zero Framework, investments in LNG dual fuel vessels offer shipowners a significantly shorter payback period than methanol, ammonia or VLSFO.

Industry coalition SEA-LNG on Wednesday (14 May) said it has completed its initial analysis of the IMO Net-Zero Framework following MEPC 83 by using the independent Z-Joule cost of compliance calculator to assess the commercial implications of the new regulations.

The calculations show that under the Net-Zero Framework investments in LNG dual fuel vessels offer shipowners a significantly shorter payback period than methanol, ammonia or VLSFO. LNG ships also give shipowners a commercial advantage through fuel optionality and access to widespread established infrastructure.

The complex IMO Net-Zero Framework now requires further detailed analysis and feedback from the industry, as well as coordination with EU initiatives and the specific concerns of other member states, prior to formal ratification later this year. There are also critical details surrounding the IMO Net Zero Fund and the zero and near-zero-emission fuels (ZNZ) Reward Mechanism that will not be addressed before 2027.

SEA-LNG’s research examines the investment case for a 14,000 TEU container vessel operating a trans-Pacific route from Japan to the US West Coast. It compares LNG, ammonia and methanol dual fuel vessels against a vessel fuelled by VLSFO over a 15-year investment period.

The total cost of the different fuel pathways is driven by CapEx, the carbon intensity of the fuels, and the fuel price. For both fuel price forecasts and carbon intensity values, SEA-LNG used assumptions from DNV’s analysis (MEPC 82/INF.8/Add.1) of the candidate mid-term measures discussed at MEPC 82.

Both high-pressure and low-pressure LNG dual fuel engines offer a relative payback period of between 4.5 and 5 years compared with VLSFO because of lower compliance costs due to LNG’s lower greenhouse gas fuel intensity (GFI). Methanol and ammonia fuelled vessels do not pay back over the 15-year investment horizon.

SEA-LNG also modelled the investment case for a 14,000 TEU containership operating on the Rotterdam-Singapore trade route using the same fuel price forecasts. In this case, the vessel is subject to both IMO and EU decarbonisation regulations – the latter for 50% of the voyage. Here the payback for LNG fuelled vessels was reduced to about 3.5 years mainly due to the effect of FuelEU Maritime in the early years of the analysis period.

Steve Esau, Chief Operating Officer of SEA-LNG, said: “While many details need to be decided, the IMO Net-zero Framework provides a clear basis for maritime decarbonisation and should, in principle, enable all fuel pathways – be they LNG, methanol or ammonia – to compete on a level playing field. For this to continue, it is imperative that the ZNZ Reward Mechanism is designed in a fuel agnostic and technology neutral way.”

Peter Keller, Chairman of SEA-LNG, concluded: “The industry continues to make major investments in the LNG pathway. These ships can use LNG, bio-methane and e-methane, and reduce greenhouse gas emissions and cut local pollution today. The IMO position, as well as the EU regulations, both affirm the pathway is heading in the right direction and offers a practical and realistic route to compliance, starting right now.”

This research is the first in a series of costs of compliance analyses SEA-LNG is developing using the Z-Joule calculator.

The IMO Net-Zero Framework is the first in the world to combine mandatory emissions limits and GHG pricing across an entire industry sector. 

Approved by the Marine Environment Protection Committee during its 83rd session (MEPC 83) from 7 to 11 April 2025, the measures include a new fuel standard for ships and a global pricing mechanism for emissions.

These measures, set to be formally adopted in October 2025 before entry into force in 2027, will become mandatory for large ocean-going ships over 5,000 gross tonnage, which emit 85% of the total CO2 emissions from international shipping.

Singapore: Bunker fuel sales increase by 4% on year in April 2025

Sales of marine fuel at Singapore port increased by 4% on year in April 2025, according to Maritime and Port Authority of Singapore (MPA) data.

In total, 4.40 million metric tonnes (mt) (exact 4,404,440 mt) of various marine fuel grades were delivered at the world’s largest bunkering port in April, up from 4.24 million mt (4,235,160 mt) recorded during the similar month in 2024.

Deliveries of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in April (against on year) recorded respectively 1.70 million mt (+6.3% from 1.60 million mt), 2.24 million mt (-0.4% from 2.25 million mt), zero (from zero), zero (-100% from 9,700 mt) and zero (from zero).

Bio-blended variants of marine fuel oil, low sulphur fuel oil, ultra low sulphur fuel oil, marine gas oil and marine diesel oil in April (against on year) recorded respectively 33,300 mt (+100% from zero), 75,600 mt (+26.8% from 59,600 mt), 700 mt (+100% from zero), zero (from zero) and zero (from zero). A new addition of biofuel blend, introduced in February this year, B100, recorded 300 mt in April.

LNG and methanol sales were posted respectively at 42,000 mt (+18% from 35,600) and zero (from zero). There were no recorded sales of ammonia for the month and so far in 2025.
