OHT inks jack-up shipbuilding contract

OHT ASA has, through its wholly owned subsidiary VIND Offshore Installation 1 AS, signed a complete shipbuilding contract with China Merchants Industry Holdings, for the construction of the first of two next-generation turbine installation vessels, following the first announcement in July.

The vessels, currently referred to as VIND 1&2, will be of GustoMSC NG-14000XL-G design. The vessels will be jack-ups, prepared to handle the next generation WTGs, featuring a telescopic crane with maximum capacity of 2,500t and a maximum lifting height of approximately 165m. The units will be capable of installing in water depths up to 65m.

Special emphasis has been placed on providing a class-leading environmental footprint by way of energy and heat recovery, battery hybrid solutions as well as a sophisticated electrical and control system, reducing CO2 emissions by 20% compared to similar units. As a future option, the vessels have been prepared for fuel cells powered by hydrogen to be installed to cut emissions even further. The first unit is scheduled to be delivered in Q2 2023.

OHT is already active in heavy transportation, having routinely transported the world’s heaviest and largest structures over the last 14 years, dominated by Oil & Gas clients. OHT saw an increasing number of opportunities in the offshore wind segment, characterised by high technical and operational complexity. Since 2017, the company has been targeting a leading position in this market, resulting in several contracts to transport offshore wind foundations.

Two years ago, OHT announced a contract to build the world’s largest foundation installation vessel – Alfa Lift – at CMHI. This vessel, to be delivered next year, is designed to execute monopile and jacket installation as a floating vessel in dynamic positioning mode.
