The first steel has been cut for Havfram’s first wind turbine installation vessel (WTIV) which is being built by Yantai CIMC Raffles Offshore shipyard in China.

In 2021, Havfram signed a letter of intent with China’s CIMC-Raffles to build a series of next-generation wind turbine installation vessels.

The NG20000X self-propelled jack-up will be able to install offshore wind turbines with a rotor diameter of more than 300 metres, as well as XXL monopiles weighing up to 3,000 tonnes at water depths of up to 70 metres.

According to Havfram, the latest battery hybrid drive train technology will be incorporated in the design to reduce carbon emission per installed megawatts of offshore wind capacity.

Havfram’s first self-propelled jack-up vessel will be equipped with the NOV variable speed drive rack and pinion jacking system, including a regenerative power system technology that feeds the generated power back into the vessel’s system.
