Singapore-headquartered marine engineering firm Seatrium on Tuesday (21 May) said it has secured an Approval in Principle (AiP) from classification society American Bureau of Shipping (ABS) for a 25,000m³ ammonia bunker vessel.
The company said the vessel has a 25,000m³ liquefied ammonia capacity, constructed using IMO Type C containment, designed by Seatrium Marine & Deepwater Technology.
The vessel is capable of dedicated ammonia bunkering with optional carrier functionality.
It is designed to operate with a deadweight tonnage of 19,500 mt at 14 knots, allowing for 55 days of operation without the need for refuelling.
The vessel’s features include enhanced safety architecture focused on preventing open-deck leaks, compliant with IMO standards, the IGC Code, and ABS regulations as well as integrated systems allowing a seamless switch between ammonia and diesel fuel.
“The ABS AiP verifies the technical viability and regulatory compliance of our vessel, creating a foundation for detailed engineering and construction,” the company said.
“This approval marks a crucial step towards timely delivery and positions Seatrium as a leader in maritime energy transition. Together, we are building a robust fuel infrastructure for the ZeroCarbon fleet of the future!”
