Huisman has been awarded an equipment contract from Penta-Ocean Construction Co. Ltd. for their new heavy lift vessel which is designed for the Japanese offshore wind market. The partnership represents Huisman’s entry to the Japanese market.
Under the contract, Huisman will deliver a 5,000mt Tub Mounted Crane along with a monopile handling system, including a Motion Compensated Pile Gripper. Developed collaboratively with Penta-Ocean Construction and vessel designer Ulstein, this innovative equipment concept seamlessly integrates the crane and handling tools into Penta-Ocean Construction’s new heavy lift vessel. The vessel is said to become the world’s first fully integrated heavy lift vessel, offering one of the highest lifting capacities globally.
Its 5,000mt active heave-compensated Tub Mounted Crane features a dual main hoist and Universal Quick Connector, enabling efficient, safe tool changes to reduce cycle time and safety risks. Key advantages of the low weight Huisman Tub Mounted Crane include a compact tail swing for deck space optimisation, no counterweight, full revolving capacity, and an in-house produced slew bearing.
The Motion Compensated Pile Gripper is specifically designed for the installation of large-diameter, variable-length monopiles over the vessel’s unique U-shaped stern. With the monopiles being stored lengthwise on the vessel, the integrated upending system enables direct handling from storage to installation. These features minimise lifting operations, while the aft installation method enhances shielding, improving the vessel’s workability and operational efficiency.
The contract marks Huisman’s fourth contract for such motion compensation system, enabling safe monopile installation from floating vessels. The partnership with Penta-Ocean represents Huisman’s entry to the Japanese market. Previous deliveries include an 800mt Pedestal Mounted Crane for the CP-8001 SEP and a 1,600mt Leg Encircling Crane for the CP-16001, reinforcing Huisman’s commitment to advanced lifting solutions in the region.
