Huisman awarded contract from Havram Wind

Huisman has announced the award of contract from Havfram Wind, an installation contractor for offshore wind turbines, for delivery of a 3,000mt+ Leg Encircling Crane for its second NG-20000X Wind Turbine Installation Vessel.

The vessel is ordered at CIMC Raffles. Huisman’s contract follows an earlier order in December 2022 for an identical crane to be installed on the first vessel.

The full electric LEC will be outfitted with a unique 155m boom and has a lifting height of approx. 180m above deck. The design has been finetuned according to specific turbine and foundation installation requirements defined by Havfram’s experienced engineering team.

The Huisman LEC is lightweight and reliable, has high positioning accuracy and is highly energy efficient, contributing to a reduced emissions footprint during the installation of increasingly large offshore wind turbines. The crane features preparations for the next generation of tagline systems, with improved capabilities to install next generations of wind turbines in more challenging conditions. Furthermore, it has been optimised for installation of bottom fixed foundations in combination with Huisman’s portfolio of Monopile Grippers and Pre-Piling Templates.

The crane features a small tail swing, offering optimal deck space. The theme of reliability and serviceability is continued in the design of the slew bearing. Huisman’s in-house designed construction in multiple segments ensures ease of inspection and maintenance.

The crane will be produced at Huisman’s production facility in Zhangzhou, China.

Håkon Johannessen, Engineering Manager of Havfram Wind AS says: “We are pleased to have Huisman supplying cranes for our newbuild Wind Turbine Installation Vessels. Huisman’s track record and willingness to tailor their already proven Leg Encircling Crane design to fit the requirements of Havfram and the market has been key to ensuring we have the right tool for the tasks that lie ahead.”

David Roodenburg, CEO of Huisman: “We are grateful that Havfram have placed their trust in us to also equip their second innovative new build vessel with a Huisman crane. They are constructing some of the world’s most energy efficient, hybrid-powered Wind Turbine Installation Vessels. We are proud that with the two crane orders, we can contribute to boosting wind energy production as well as further improving energy efficiency to reduce Havfram’s carbon footprint.”
