ClassNK Issues AiP for Hydrogen-Fueled Oil Tanker

ClassNK has awarded an Approval in Principle (AiP) for a groundbreaking design concept of a hydrogen-fueled oil tanker with an electric propulsion system. The 5,000KL vessel, developed collaboratively by UYENO TRANSTECH LTD., YANMAR POWER TECHNOLOGY CO., LTD., and Mitsui E&S Shipbuilding Co., Ltd., marks a significant milestone as the world’s first oil tanker to use liquefied hydrogen as fuel.

This innovative ship design is part of the “Development of Large-scale Hydrogen-fueled Domestic Tanker and Demonstration of Zero-Emission Ships” project, funded by the Nippon Foundation. The initiative aims to advance the use of hydrogen in maritime transport, promoting zero-emission shipping solutions.

Hydrogen-fueled Vessel Wins AiP Towards Demonstration Operation

ClassNK‘s rigorous review process involved assessing the ship’s design against its “Rules and Guidance for the Survey and Construction of Steel Ships,” which includes the IGF Code and specific guidelines for ships using alternative fuels and fuel cell power systems. After confirming compliance with these stringent requirements, ClassNK issued the AiP, marking the first such certification based on the newly released Part D of the “Guidelines for Ships Using Alternative Fuels.”

ClassNK’s commitment to safety and environmental sustainability is evident in its support for this pioneering project. The organization will continue to contribute to the project’s development, emphasizing safety evaluations and aiding the shipping industry’s decarbonization efforts.
