Fred. Olsen Windcarrier has announced that it is upgrading one of its Gusto 9000 jack-up vessels with a new crane that will be able to install foundations up to 1,500t and all known next generation offshore wind turbines.

The unique 1,600t leg encircling crane will be the highest on the market when it is delivered, in 2022. The new and improved crane vessel has the following key features:

• Aux hook 400t @165m above deck (140m boom)
• 1250t@38.5m @155m above deck (140m boom)
• 1600t@32m (105m boom)
• Boom configuration can be changed in less than a week
• Additional speed packages provide a very high operational speed
• The Lambda shaped boom is very stiff giving reduced motions at the crane tip
• The crane is fully electrically driven resulting in reduced maintenance and higher reliability
• The crane is more environmentally friendly with less power consumption, no oil leakage and a lower
noise level
• Catchers on all blocks/hooks minimise time spent on stowing
• Small tail swing allows for optimised utilisation of free deck space

Huisman will supply the new LEC 65500 crane. Its Regional Director, Jan Atle Andresen, described the vessel as “unique and suitable” for its new purpose on account of its “compact size”, “low weight”, and “high lifting capacity”.

Even Larsen, CEO of Fred. Olsen Ocean, 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.”

Alexandra Koefoed, Managing Director at Fred. Olsen Windcarrier, added: “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.”
