New design for ammonia-fueled Ammonia Bunkering Vessel granted AiP
Through our collaboration with NYK Line and Seatrium, LMG Marin have developed a new ship design concept for an Ammonia Bunkering Vessel that will also use ammonia as fuel. This groundbreaking ship design has now been granted Approval-in-Principle (AiP) by classification society ClassNK.
From NYK Line press release:
“Seatrium’s technology company, LMG Marin supported the consortium’s initiative with its vast technical capabilities and proven track record in designing complex maritime systems. LMG Marin provided cutting-edge design capabilities, leading to a Hazard Identification Study (HAZID) for design validation. The comprehensive HAZID conducted was instrumental in fulfilling the requirements of the AiP to ensure optimal safety, performance, and operational reliability. Through this concept design phase, safety philosophies on the safe use of ammonia for the ammonia fuelled engines in the engine room were developed to ensure compliance with the International Maritime Organisation’s interim guidelines for the safety of ships using ammonia as fuel, approved by the Maritime Safety Committee 109 in December 2024.
Also, the vessel design incorporates the consortium’s two key features to ensure safety and operational reliability: ammonia fuel dual-fuel engines from IHI Power Systems and a bunkering boom by TB Global Technologies. The engines significantly reduce GHG emissions using ammonia as a fuel. They are also installed on the world’s first commercial-use ammonia-fuelled tugboat, Sakigake, delivered in August 2024. The bunkering boom features a unique technology called the High Speed Ammonia Purging Emergency Release System (ERS), which enables a reliable and efficient disconnection between vessels in an emergency.
Aziz Merchant, Executive Vice President for Engineering, and Technology & New Product Development, Seatrium, and Chairman of LMG Marin, commented: “We are honoured to contribute to this industry-leading initiative led by NYK and its partners. The use of ammonia as a non-fossil-based marine fuel is a key distinction in this project. Collaborating on this visionary project reaffirms Seatrium’s commitment to advancing sustainability and supporting global decarbonization goals.”
By enhancing the feasibility of ammonia as a future fuel, this project positions the consortium at the forefront of the maritime energy transition.
The design will now be submitted to the Maritime and Port Authority of Singapore (MPA) for evaluation.
