Fred Olsen Windcarrier is upgrading one of its Gusto 9000 jack-up vessels with a new Huisman crane that will be capable of installing up to 1500-tonne foundations and all known next generation offshore wind turbines.
The 1660-tonne Huisman LEC 65500 leg encircling crane will be delivered in 2022 and will be the highest in the market, Fred Olsen Windcarrier said.
The crane will have a 400-tonne aux hook at 165 metres above deck with 140-metre boom, 1250 tonnes at 38.5 metres at 155 metres above deck, and 1600 tonnes at 32 metres with a 105-metre boom.
Fred Olsen Windcarrier said the boom configuration can be changed in less than a week.
Fred Olsen Ocean chief executive Even Larsen said: “With this new crane, we are gearing up for the next generation of offshore wind turbines.
“After installing more than 600 offshore turbines, we continue to set our sights higher and higher, knowing that our clients need a partner who can support them in establishing tomorrow’s offshore wind gigaparks.”
Fred Olsen Windcarrier managing director Alexandra Koefoed said: “This unique crane has been enhanced with an even more extreme boom and outreach capacity.
“The crane allows us to stow the wind turbine components in a more flexible way despite the increased crane weight, thus maintaining or exceeding the payload we carry for our clients. Furthermore, blades can be installed with the faster auxiliary hook and in higher wind speeds.
“All together this is a considerable lifetime extension for the vessel, as the weight and dimensions of wind turbine components continues to increase.”
Huisman Norge regional director Jan Atle Andresen said: “The compact size of the new crane in combination with its low own weight and high lifting capacity make the crane unique and suitable for both the installation of foundations and next generation wind turbines.
“Over the last years we have established a unique working relationship with Fred. Olsen Windcarrier and this is a great example of two leading companies working together and combining their knowledge and experience in the field of cranes and installation.”
