Yantai’s dual-fuel methanol WTIV design receives ABS approval

In a significant development for the renewable energy sector, ABS, a leading classification society, has awarded approval in principle (AIP) to Yantai CIMC Raffles Offshore Ltd., a renowned Chinese shipbuilding company, for their groundbreaking design of a dual-fuel methanol offshore wind turbine installation vessel (WTIV).

The cutting-edge WTIV is meticulously engineered to facilitate the transportation and installation of the largest wind turbines globally, boasting an impressive capacity of up to 20 megawatts (MW) of electricity production. What sets this vessel apart is its innovative dual-fuel methanol propulsion system, promising a substantial reduction in carbon emissions. Additionally, the design incorporates a robust 3,500-ton leg encircling crane and a sophisticated sea-keeping dynamic positioning system (DPS), ensuring compliance with ABS class requirements DPS-2.

Crafted primarily for the European market, this state-of-the-art vessel boasts remarkable specifications, including a maximum lifting weight of 3,500 tons and a lifting height of 228 meters above sea level. It is equipped to accommodate either seven sets of 14 MW or four sets of 20 MW wind turbine components. Emphasizing a commitment to environmental sustainability, the vessel features a dual-fuel main engine and a hybrid battery system, effectively reducing both carbon emissions and fuel consumption.

Amidst challenging market dynamics and a shortage of support vessels like WTIVs, Yantai’s innovative design emerges as a promising solution to meet the demands of high-capacity offshore wind projects. Beyond offering improved economics, this design enhances competitiveness in the ever-evolving industry landscape, paving the way for sustainable energy development.
