MAN Cryo wins nod from DNV, BV for ammonia fuel supply system

MAN Cryo, part of Germany’s engine producer MAN Energy Solutions, revealed that its design for an ammonia fuel supply system has been awarded Approval in Principle (AiP) from classification societies DNV and Bureau Veritas.

MAN Cryo developed the system in cooperation with Chinese company Yada Green Energy Solutions, with whom the company has previously cooperated to provide equipment for LNG and methanol marine fuels.

“Facing the climate-change issue, no one can solve it alone and we firmly believe that cooperation is a powerful means of achieving this. YADA and MAN Cryo are customer-centric operators, providing high-quality, dual-fuel system solutions and continuously achieving new breakthroughs in handling methanol and ammonia,” Xiang Guangqing, Chairman, Yada Green Energy Solutions, said.

“Yada Green Energy Solutions has set ambitious goals to accelerate the green transformation of the global-transportation industry. Working together to support global development, understanding and anticipating customer needs is an important driving force for our daily work. MAN Cryo and YADA will unite with industry peers, embrace innovation and cooperation, and jointly move towards the sustainable future of global shipping.”

“We are pleased to announce the successful achievement of a significant strategic milestone for MAN Cryo in cooperation with Yada Green Energy Solutions. This accomplishment underscores our unwavering commitment to our global customer base as we collectively work towards a decarbonised world. The establishment of a secure and reliable fuel-supply system for future ammonia engines marks a pivotal development,” Henrik Malm, Managing Director, MAN Energy Solutions Sweden, commented.

“Ship owners can rest assured that MAN Cryo, in cooperation with Yada Green Energy Solutions, is delivering a market-ready solution adhering to the highest security standards and embodying world-class engineering.”

A month ago, MAN ES, in collaboration with compatriot stainless steel processor Butting, said that the world’s first selective catalytic reduction (SCR) converter intended for an ammonia engine had passed its factory acceptance test.

Measuring an impressive 3.9 meters in diameter and boasting a weight of 28 metric tonnes, the Cluster 5 Double Layer, built by Butting, has been described as the largest SCR converter built to date. It is also the world’s first SCR (High Pressure) designed for a commercial two-stroke ammonia engine.

What is more, MAN ES signed a contract last week with Turkish powership builder and owner Karpowership for the delivery of a total of 48 dual-fuel engines for Karpowership’s fleet of power plant ships.
