Classification Society ClassNK granted approval in principle (AiP) to NS United Kaiun Kaisha and Imabari Shipbuilding for their joint project on the concept design of an LNG-fueled capesize bulker.

The AiP has been awarded based on ClassNK’s Rule Part GF which adopts IGF Code, regulation for ships using low-flashpoint fuels, the classification society said in its statement.

The design features two Type C LNG tanks at the stern which enable the construction of an LNG-fueled vessel without significant changes to the conventional vessel’s basic design.

The design adopts a low-pressure dual-fuel engine for the main engine, which enables the use of gas that has naturally vaporized (BOG) from the LNG tanks in the main engine without any waste, the statement reads.

“This basic design can achieve CO2 emission volumes that are 30 percent less than the reference line as required under EEDI Phase 3 by the IMO,” ClassNK said.
