ABS Approves Yantai's Dual-fuel Methanol WTIV Design

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.

ABS reaffirms its dedication to supporting clients in their journey towards decarbonization by facilitating alternative fuel solutions. Methanol, recognized as a readily available and practical technology, emerges as the preferred choice in new designs, establishing itself as a tangible solution to address environmental concerns and meet energy demands sustainably. With this milestone approval, ABS and Yantai CIMC Raffles Offshore Ltd. set a new standard in offshore wind energy infrastructure, driving progress towards a cleaner and greener future.

Yantai CIMC Raffles Offshore Ltd. specializes in the manufacturing of offshore vessels and marine engineering equipment. The company is known for its expertise in designing and producing a variety of offshore platforms, including semi-submersible platforms, jack-up platforms, floating vessels, pipe-laying vessels, and other specialized offshore vessels.

The American Bureau of Shipping (ABS) is a renowned maritime classification society founded in 1862. Its primary mission is to enhance the safety and security of life, property, and the environment, primarily by establishing and verifying standards for the design, construction, and operational maintenance of marine and offshore assets. ABS's main focus is on providing classification services globally to the marine, offshore, and gas industries. As of 2020, ABS ranked as the second-largest classification society, with a classed fleet comprising over 12,000 commercial vessels and offshore facilities.
