Sasaki Shipbuilding gets BV AiP for methanol dual fuel system

French classification society Bureau Veritas (BV) has granted approval in principle (AiP) to Japanese shipbuilder Sasaki Shipbuilding for its methanol dual fuel (DF) system applied in a 9,000 dwt general cargo ship.

This achievement is said to represent a significant advancement in sustainable shipping technology, contributing to the global efforts towards reducing emissions and promoting decarbonization in the maritime industry.

As explained, the integration of the methanol DF system into the ship demonstrates its feasibility for smaller-scale ships, highlighting its adaptability and efficiency as a marine fuel.

Even though similar systems exist on larger vessels, this AiP reaffirms the potential of methanol for environmentally friendly propulsion in diverse maritime applications, according to BV.

Sasaki Shipbuilding, specializing in the construction of small and medium-sized vessels, is committed to developing ships that utilize new fuels, aligning with the industry’s sustainability goals. For the purpose of the AiP, Bureau Veritas conducted a comprehensive review of Sasaki’s methanol dual-fuel system, meticulously assessing its compliance with the stringent requirements outlined in BV’s Rule Note NR 670 – Methanol & Ethanol Fuelled Ships.

The AiP presentation ceremony, held on March 25, 2024, symbolized the collaborative efforts between Bureau Veritas and Sasaki Shipbuilding in advancing sustainable shipping solutions.

“Bureau Veritas is committed to supporting the development and adoption of new fuels, such as methanol, as part of our broader mission to drive environmental stewardship and innovation within the industry. The adoption of Methanol Dual Fuel systems on vessels of this size underscores the versatility and practicality of methanol as a marine fuel. We commend Sasaki for their dedication to sustainability and look forward to furthering our partnership in developing innovative solutions for the maritime industry,” Alex Gregg-Smith, Senior Vice President & Chief Executive, North Asia and China, Bureau Veritas Marine & Offshore, commented.

In February, an ammonia bunkering vessel designed by Sasaki Shipbuilding also won AiP from BV.

The 12,000 cbm NH3 bunkering vessel design is based on a joint study of ammonia bunkering rules between MOL and BV.
