Huisman has won a contract from Vard, a designer and shipbuilder, for the delivery of a fully electric 250-mt Hybrid Boom Subsea Crane and a 100-mt Knuckle Boom Crane. The cranes will be installed on Toyo Construction’s latest cable-lay and construction vessel.

Tokyo Construction 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 is said to signify a milestone in advancing capabilities for cable-laying and turbine foundation installation works in the Japanese offshore wind sector.

Huisman‘s Hybrid Boom Crane features a fully electric traction and storage winch design that ensures secure storage of large diameter subsea wire rope. Equipped with both hydraulic passive and active heave compensation systems, this crane guarantees superior workability offshore. Designed to meet the specific requirements and preferences of Toyo Construction, the crane will undergo certification according to ClassNK regulations.

The 250-mt 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. It features a superior load curve for optimised deck handling and overboarding of voluminous structures, such as suction anchors or pinpiles. In addition, it can lower the knuckle for an improved operational weather window, significantly reducing motions during offshore lifting operations.

The 100-mt 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 to handle cargo efficiently across the deck.

Both cranes will be manufactured at Huisman’s state-of-the-art production facility in Zhangzhou, China.
