SCHIEDAM, The Netherlands — Huisman has been awarded a contract by Seaway7, part of Subsea7 Group, for the delivery of the entire monopile installation spread for jackup 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 maximize the vessel payload. For this new design, Huisman applied the technology of its existing range of grippers, which resulted in a lightweight, robust and very stiff monopile gripper capable of handling XXL monopiles, the company said.
In addition, 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, Huisman said.
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 fourth-quarter 2024.
