Ulstein has refined its heavy lift vessel design for handling the next generation of offshore wind monopile and jacket foundations.
The Ulstein HX118 design is the third evolution of the SOC 5000, of which several vessels are in operation or under construction, including Heerema’s Aegir and Subsea 7’s Seven Borealis.
The HX118 features a 5000 mega-tonne main crane with large lifting heights and a large, strong open deck, said the vessel outfit.
Methanol powered generators, an optimised hull design and smart integration of battery systems ensure low emissions during operations and when in port.
“We worked four years on the development of this design, using our unique ‘ULSTEIN Blended DesignTM‘ methodology, CFD simulations, and knowledge gained from the ALFA LIFT design and Aegir conversion”, said Ko Stroo, lead naval architect/product manager in Ulstein Design & Solutions.
“Combining our vast track record in heavy lift vessels with business case analysis and latest installation technologies resulted in what basically is the Mk3 version of our SOC 5000 design.”
The company has already received favourable pricing in relation to its latest design “from multiple yards worldwide” said managing director Edwin van Leeuwen, adding, “So, all ingredients are available to the industry to push the button, get into a yard contract and get delivery in 2025.”
