Texas-based NOV has once again been awarded contracts for the equipment and design of a GustoMSC™ NG-16000X wind turbine installation jack-up vessel for Eneti.
This will be Eneti’s second next-generation jack-up vessel, and the contracts include an option for an additional jack-up vessel, NOV said.
NOV will provide the design and jacking system for the vessel, which will be built at the Daewoo Shipbuilding and Marine Engineering Co., Ltd. shipyard in South Korea. Delivery is scheduled for the second quarter of 2025.
Both of Eneti’s wind turbine installation vessels are of the same series and are ready to carry multiple 20 MW turbine sets. The vessels have been designed with the option to adapt in the future, allowing them to operate on alternate fuels, NOV said.
The NG-16000X design includes the GustoMSC rack and pinion jacking system with a variable speed drive. The jacking system features a regenerative power option where the generated power is fed back into the vessel system. The design further incorporates a 2,600-ton leg encircling crane, ready to install monopile foundations and wind turbines. The vessel can install turbines at depths of up to 65 metres of water.
”We worked closely with Eneti to have their first NG-16000X ready for construction, and now the second is ordered according to plan,” said Commercial Director of GustoMSC Jan-Mark Meeuwisse.
”Eneti also acquired the shares of Seajacks, expanding their fleet with five existing GustoMSC-designed jack-ups. This, combined with the two NG-16000X new builds, shows Eneti’s commitment to this offshore wind installation market.”
Presently worldwide, three NG-16000X designs are under construction and all are optimized, self-propelled wind turbine installation jack-up vessels that feature increased carrying and lifting capacity, as well as greater lifting height above the deck.
”The shortage of wind turbine installation jack-ups capable of installing heavier and higher turbines in deeper waters is foreseen,” Meeuwisse said.
”The GustoMSC team prepared for this change. This includes actively seeking ways to further reduce greenhouse gas emissions, contributing to the reduction of the industry carbon footprint. The alternate fuel and regenerative power options, combined with our century-and-a-half of experience in the offshore maritime sectors and our pioneering spirit, make us a leading partner for our clients.”
