HOUSTON – NOV will design and supply jacking system equipment for GustoMSC’s NG-16000X design wind turbine installation jackup vessel on behalf of Eneti.
The vessel, to be built at the DSME shipyard in South Korea, is due to be delivered in 3Q 2024. The contract carries an option for a further jackup vessel.
According to GustoMSC, the NG-16000X design provides for higher carrying and lifting capacity, and an increased lifting height above the deck. It was developed from the same series as the first US-built NG-16000X and is said to be ready to carry multiple 20-MW turbines.
In addition, the design provides the option to adapt the vessel to operate in future on alternate LNG or ammonia fuels.
Features includes the GustoMSC rack and pinion jacking system with a variable-speed drive, said to enable several hundreds of jacking moves throughout the lifespan of the vessel.
Its jacking system will have a regenerative power option in which the generated power is fed back into the vessel system. A 2,600-t leg encircling crane can be deployed to install future-size monopile foundations and wind turbines.
