Japanese classification society, ClassNK has granted what it says is the world-first AiP to Imabari Shipbuilding for their concept design of a 180,000dwt LPG dual fuelled bulk carrier. The design was developed in cooperation with Mitsubishi Shipbuilding.
The AiP was granted to the concept design based on the Society’s Guidelines for Ships Using Low-Flashpoint Fuels and 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), the current IMO Res. MSC.391(95) and the MSC.458(101) revision planned for release in 2024.
The main features of the design announced by Imabari Shipbuilding are it eliminates the necessity for special consideration of boil off gas with this design handling LPG at room temperature and high pressure, which makes the ship’s operation easier. In addition, the ship has been designed with extensive consideration towards cost competitiveness by eliminating the use of low-temperature materials such as stainless steel and cryogenic insulation. The LPG tank is planned/designed to be installed in the aft area of the bridge and to have a round-trip distance capacity between Japan and Australia.
