Tsuneishi Shipbuilding on Wednesday (14 May) said it has delivered the world’s first methanol dual-fuel Ultramax bulk carrier, Green Future. 

The 65,700 dwt vessel was delivered at its factory on 13 May and will be chartered by NYK Bulk & Projects Carriers, an NYK Group company, from Kambara Kisen.

Tsuneishi Shipbuilding said the vessel maintains the high cargo capacity and fuel efficiency characteristic of the TESS66 Aeroline design series, while enabling more sustainable operations through the use of methanol as a fuel.

The methanol fuel tank has been positioned to maximise safety and facilitate smooth cargo handling while maintaining loading efficiency. It is also equipped with a fuel-efficient main engine and Tsuneishi’s proprietary Aeroline technology to reduce wind resistance, delivering superior fuel performance.

Mr Okumura Sachio, Representative Director, President & Executive Officer of Tsuneishi Shipbuilding, said: “This delivery marks just the beginning. We will continue constructing methanol dual-fuelled vessels at our overseas facilities and remain steadfast in our pursuit of technological innovation to contribute to a more sustainable maritime industry and global environment.”

NYK said the vessel is the first bulk carrier in the NYK Group to be equipped with a dual-fuel engine that uses methanol and fuel oil.

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.
