ABS Grants AiP to New Dual-Fuel Vessel Design Concept

Algoship's Seatransporter-DF design has received AiP from ABS.

ABS Friday announced that it has granted Approval in Principle (AIP) to Bahamas-based Algoship Designers Ltd.'s (Algoship's) dual-fuel design concept, known as Seatransporter-DF, which can accommodate multiple engine types, including a Type-C or membrane containment systems for liquefied natural gas (LNG) fuel.

The Seatransporter-DF is said to have been designed in order to comply with current and upcoming international air emission standards, including those set out for Emission Control Areas (ECAs).

"Technically innovative designs that advance the use of LNG as fuel will play an increasingly important role in the marine sector, and ABS is working alongside industry to enable this critical technological advancement," said Dr. Kirsi Tikka, Executive Vice President for Global Marine at ABS.

"As industry considers future fuel strategies, design concepts that promote the use of LNG as fuel will play an increasingly important role in that mix."

Algoship is said to have worked with U.S.-based CleanShips LLC (CleanShips) to develop a version of the bulk carrier design to fulfil specific operational requirements while still maintaining cargo carrying capacity.

ABS explains that the 38,000 DWT version of the design is equipped with a 2,400 m3 LNG fuel containment system that enables approximately 100 days of endurance, with Algoship applying the same design philosophy to Panamax, Ultramax, and Kamsarmax sizes.

"ABS contributed to this effort as a trusted advisor, engaging early in the process to apply its rigorous engineering and safety standards and verify the feasibility of the design," said Antony Prince, President of Algoship.

"By working with ABS through its AIP process, we've been able to demonstrate that the Seatransporter was developed with a focus on safety and reliability and will be able to satisfy flag and port state requirements."

In January, ABS released a new guide for LNG bunkering, which outlines requirements for the design, construction, and survey of carriers and barges fitted with dedicated LNG transfer arrangements and intended for regular LNG bunkering service.
