ClassNK has granted an Approval in Principle (AiP) to Imabari Shipbuilding for its concept design of a 180,000 dwt LPG dual fuelled bulk carrier 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. This was the first LPG dual fuelled bulk carrier to be granted an AiP.

The design eliminates the necessity for special consideration of boil off gas, handling LPG at room temperature and high pressure, which makes the ship’s operation easier. In addition, the ship has been designed with consideration towards cost competitiveness by eliminating use of low-temperature materials such as stainless steel and cryogenic insulation. The LPG tank is planned to be installed in the aft area of the bridge and with round-trip distance capacity between Japan and Australia. With LPG supply bases and infrastructure facilities globally more developed and improved, this makes the ship’s operation more flexible.
