Japan-based classification society ClassNK has 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., for their KAMSARMAX GF concept design of an LNG-fuelled bulk carrier.
ClassNK has conducted its review and issued the AiP on the concept design of the KAMSARMAX GF, which has installed a dual-fuel engine using LNG as the main fuel and an IMO Type C Fuel tank according to its Rule Part GF.
The main features of the system announced by Tsuneishi Shipbuilding are as follows:
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.
