Huisman has been awarded a contract from VARD for the delivery of a full electric 250mt Hybrid Boom Subsea Crane, and a 100mt Knuckle Boom Crane destined for integration into Toyo Construction Co. Ltd.'s latest cable-lay and construction vessel.

Toyo Construction Co. Ltd. will welcome this vessel as the latest addition to its fleet, specially designed for the Japanese offshore wind industry. The purpose-built VARD 9 15 design signifies a milestone in advancing capabilities for cable-laying and turbine foundation installation works in the Japanese offshore wind sector.

Huisman's Hybrid Boom Crane stands out for its features, including a fully electric traction and storage winch design that ensures secure storage of large-diameter subsea wire rope, as well as both passive and active heave compensation systems. Designed to meet the specific requirements and preferences of Toyo Construction Co. Ltd., the crane will undergo certification according to ClassNK regulations.

The 250mt Hybrid Boom Crane is a proven subsea crane concept that combines the high lifting height of a conventional lattice-type boom crane with the operational advantages of a Knuckle Boom Crane.

The 100mt Knuckle Boom Crane, part of Huisman's recently launched Subsea Crane range for offshore construction vessels, is a compact yet powerful subsea-rated crane. Featuring active heave compensation, this crane is designed to assist in subsea work and handle cargo efficiently across the deck. Both cranes will be manufactured at Huisman's state-of-the-art production facility in Zhangzhou, China.

Features & benefits of the Huisman Hybrid Boom Crane

- Superior load curve for optimized deck handling and overboarding of voluminous structures, such as suction anchors or pinpiles.

- Ability to lower the knuckle for an improved operational weather window, significantly reducing motions during offshore lifting operations.

- Fully electric-driven subsea winch package enabling significantly lower power consumption of the crane system.

- Hydraulic active and passive heave compensation, allowing for the precise lowering of loads through the splash zone and accurate landing on the seabed.
