Anglo Belgian Corporation and Jan De Nul Group announce the successful completion of the Factory Acceptance Test (FAT) for the first 12DV36 methanol dual-fuel engine, marking a significant milestone in the construction of the state-of-the-art XL cable-laying vessel, Fleeming Jenkin. This achievement validates the operational reliability and performance of the innovative dual-fuel engines, paving the way for their integration into the vessel.
In October 2023, Jan De Nul and ABC signed a contract for the delivery of four 12DV36 methanol dual-fuel engines (each with a power output of 7,200 kW). These engines are designed for maximum fuel flexibility and can operate on methanol, (bio)diesel, and HVO. The new XL cable-laying vessel Fleeming Jenkin will be the first Ultra-Low Emission Vessel (ULEv EURO VI) to utilise these methanol dual-fuel engines.
The FAT took place at ABC’s factory in Ghent, under the supervision of Bureau Veritas (BV) and representatives from Jan De Nul, including the Chief Engineers of the Fleeming Jenkin. During the test, the engine demonstrated outstanding performance in both methanol and (bio)diesel modes, with stable operation across various load points. The new groundbreaking aftertreatment system now achieves NOx emissions more than 83% below the IMO Tier III standard—an important measure to reduce nitrogen deposition in nature.
Edward Belderbos, Project Engineer at Anglo Belgian Corporation, stated: “The successful completion of the FAT confirms that our methanol dual-fuel engines are not just a theoretical concept but innovative machines proven in practice. During the tests, we demonstrated that the engine maintains stable operation under various load conditions on both methanol and (bio)diesel. This result underscores ABC’s innovative strength and our commitment to the highest quality standards.”
A FAT is a comprehensive testing procedure to ensure that an engine meets all design and performance requirements. Parameters such as oil pressure, cooling water temperature, speed stability, and power output are verified under simulated operational conditions. Additionally, functional systems such as control and monitoring systems are tested to minimise risks during commissioning.
The first methanol dual-fuel engines will soon be shipped to the CMHI shipyard in Nantong, China, where they will be integrated into the new vessel.
