Leading Classification Society ClassNK approved an Approval in Principle (AiP) to Imabari Shipbuilding Co.,Ltd for their idea layout of a 180,000 DWT LPG dual-fuelled mass service provider established together with Mitsubishi Shipbuilding Co., Ltd.
The AiP was provided to the idea layout based upon the Society’s Guidelines for Ships Using Low-Flashpoint Fuels(* 1) and also its Rule Part GF (guideline for ships making use of low-flashpoint gas) including “International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code)”, the existing IMORes MSC.391( 95) and also the MSC.458( 101) modification prepared for launch in 2024. This was the initial LPG dual-fuelled mass service provider worldwide to be provided an AiP.

The highlights of the layout revealed by Imabari Shipbuilding are as adheres to:
“As one of the merits of this design, 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 to use low-temperature materials such as stainless steel and cryogenic insulation. LPG tank is planned/designed to be installed in the aft area of the bridge and with round-trip distance capacity between Japan and Australia. And, as for supplying LPG to the ship, nowadays, LPG supply bases and infrastructure facilities are globally more developed and improved, which makes the ship’s operation more flexible. This is another motivation to create this design.”
(* 1) Alternative gas besides LNG (Methanol/Ethanol/ LPG) have actually reduced flashpoints contrasted to standard gas, as a result certain interest requires to be offered to making certain ample safety and security preventative measures when making use of low-flashpoint gas in order to lower the prospective threat of fire and also surges that might emerge as an outcome of gas leak onboard the ship. International safety and security needs for low-flashpoint gas have actually been talked about at IMO and also because of this, the International Code of Safety for Ships making use of Gases or various other Low- flashpoint Fuels (IGF Code) has actually been embraced and also applied. The existing code nonetheless, does not resolve details policies for different gas besides LNG. Accordingly, in 2019 ClassNK launched standards that detail safety and security needs for various other sensible different gas besides LNG, based upon the most up to date innovation and also guideline patterns in order to advertise the layout of different sustained ships.
