Huisman has been awarded a contract by Seaway7, part of Subsea7 Group, for the delivery of the entire monopile installation spread for jack-up vessel Seaway Ventus, consisting of a Monopile Gripper, an Upending Frame, and two sets of Monopile Storage Cradles.

Huisman has modified its existing gripper design to meet Subsea7’s requirement to maximise the vessel payload. For this new design Huisman applied the proven technology of its existing range of Grippers. This has resulted in a lightweight, robust and very stiff Monopile Gripper, capable of handling XXL monopiles.

Huisman has paid special attention to optimizing the upending process. The Monopile Upending Frame is adjustable in length and therefore suitable for handling a wide range of monopiles.

The Monopile Storage Cradles are outfitted with adjustable saddles to be able to store various monopiles sizes. The cradles can be expanded with an additional layer to double the vessel’s storage capacity.

Since the Seaway Ventus will be deployed for monopile as well as wind turbine installation, Huisman has taken into account easy and quick (de)mobilization of the monopile installation spread. The equipment will be integrated in the vessel in such a way that the permanent installed parts are kept to a minimum, further maximizing the payload.

The monopile installation spread will be engineered, built, and installed on the Ventus at Huisman’s premises in Schiedam, the Netherlands. Delivery is scheduled for Q4, 2024.
