ClassNK grants AiP for LNG-fuelled bulker

(Posted on 20/12/19)

Leading Classification Society ClassNK granted an Approval in Principle (AiP) based on its Rule Part GF which adopts IGF Code (regulation for ships using low-flashpoint fuels) to NS United Kaiun Kaisha, Ltd. and Imabari Shipbuilding Co., Ltd. for their joint project on the concept design of an LNG-fuelled capesize bulker.

The main features of the design announced by Imabari Shipbuilding are as follows.

“By installing two Type C LNG tanks at the stern, which are considered to be cost competitive and are comparatively easily to install, it is possible to build an LNG-fuelled 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: boil-off gas) from the LNG tanks in the main engine without any waste, thereby reducing the burden on the environment and lowering running costs.

This basic design can achieve CO2 emission volumes that are 30% less than the reference line as?required under EEDI Phase 3 by the IMO.”

The Imabari Shipbuilding Group specializes in constructing and repairing a wide range of ships. More than 90 ships are constructed annually based in 10 shipyards in Japan.

ClassNK is actively engaged in a growing range of ship related activities and services aimed at contributing to promoting the protection of human life and property at sea as well as protection of the marine environment.
