Havfram Hybrid Mega Jack-Ups to Feature ABB Tech

ABB has secured an order from China’s Yantai CIMC Raffles Offshore to deliver an integrated bridge-to-propeller technology for Havfram Wind’s two new NG20000X-HF wind turbine installation vessels (WTIVs).

ABB scope comprises four Azipod electric main propulsion units with a total propulsion power of 17 MW; the Onboard DC Grid power distribution system; a 4.1 MWh energy storage installation; ABB Ability Marine Pilot Control with Dynamic Positioning System for advanced vessel control, as well as a comprehensive package of automation and digital technology.

Designed to optimise vessel responsiveness, efficiency, and safety across the entire operating profile, ABB Ability Marine Pilot Control allows for a seamless transition from position control to joystick maneuvering, said ABB.

The DP2 functionality could add redundancy in technical design, ensuring that in the event of a single system fault, the vessel’s position will be maintained.

“To ensure superior performance, we chose the broad scope of ABB power, control, propulsion and automation technology, complemented by the through-life support from ABB’s remote diagnostics and global service capabilities”, said Even Larsen, CEO of Havfram Wind.

The NG20000X-HF vessel will be among the largest wind installation jack-ups in the industry.

The ship will feature a 3,250-tonne heavy-lift crane which will be able to install foundations up to 3,000 tonnes and wind turbines with tip heights over 300 metres in water depths up to 70 metres.

Its large carrying capacity will reduce the number of vessel trips required per development, thereby improving project economics and reducing carbon emissions per installed megawatt, according to NOV, the company responsible for the design of the vessel.
