Classification society ClassNK on Wednesday (16 June) granted an Approval in Principle (AiP) based on its Rule Part GF (regulation for ships using low-flashpoint fuels) incorporating “International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code) to Tsuneishi Shipbuilding Co., Ltd for their concept design of a liquefied natural gas (LNG) fuelled bulker “Kamsarmax GF”.
The concept design of “Kamsarmax GF” is based on a dual-fuel engine using LNG as the main fuel and an IMO Type C Fuel tank according to ClassNK’s Rule Part GF.
As more environmental technologies have been developed to realize a low-carbon and decarbonised society in the maritime industry, developments of LNG-fuelled ships have progressed in a variety of ship types and sizes, said ClassNK.
The GF in “Kamsarmax GF” stands for Gas Fuel. This eco-ship combines the versatility of Kamsarmax with the high environmental performance of LNG fuel.
Designed to use LNG as its primary fuel, it has achieved a reduction of carbon dioxide (CO2) emissions by 40% or more compared to the EEDI reference line and meet the reduction rate by a large margin for EEDI Phase 3 that will take effect in 2025.
In addition, sulphur oxides (SOx) and nitrogen oxides (NOx) have also been greatly reduced.
