Hyundai Heavy gives shipping a glimpse of its potential ammonia future

Hyundai Heavy Industries (HHI), South Korea’s number one shipbuilder, has given the world a glimpse of what an ammonia-fuelled ammonia carrier will look like.

The shipbuilder has just won approval in principle (AiP) for its design from France’s Bureau Veritas – the ship baring many similarities to today’s very large gas carriers (VLGCs).

The vessel will be 227 m long, 36.6 m wide, and 23.6 m deep – similar dimensions to that of the HHI 91K VLGC design. It will be equipped with four prismatic-type cargo tanks with a total capacity of 91,000 cu m.

“This design was optimised for the safe and efficient carriage of ammonia as a single cargo, thereby maximising competitiveness for shipowners, both in terms of CAPEX and OPEX,” stated a release from Bureau Veritas.

Ammonia is one of the main alternative fuel options currently considered by shipping for net zero operations.

  1. The post on ammonia gas carrier is indeed a stupendous news as ammonia gas has a tremendous potential for being considered and developed as alternative fuel in shipping industry. Since the design of the ship has been optimised and approved in principle by Bureau Veritas, the shipping industry will definitely grow by leaps and bounds.
