The Seajacks Hydra, a jack-up vessel owned by Seajacks UK Ltd., was commissioned within 10 days at Damen Shiprepair Rotterdam, which is part of Damen Shiprepair & Conversion. In late July, a heavy-lift vessel shipped the Seajacks Hydra platform into the port of Rotterdam. Seajacks Hydra was towed to the repair yard.
It was a time-constrained project since the platform had to be delivered to a project of Seajacks which started in August. In spite of the tight schedule, Hydra was delivered on time.
The scope of work was among other the installation of four azimuth thrusters (rudder propellers). The Seajacks Hydra was jacked-up 8 meters above the water surface, while divers kept an eye on the process and the soil condition. Jacking-up is permitted on only a limited number of locations in the Port of Rotterdam. In order to jack-up a vessel the soil needs to be mapped and one must possess information about the depth, layering and capacity of the soil.
The platform would initially be commissioned by another reparation company, also located in the Port of Rotterdam. Last minute they were not able to clear a location. However, Damen Shiprepair & Conversion was able to provide a location and deliver the platform before the deadline.
Various departments of Seajacks were involved in the repairing process, from: Logistic, Procurement, Technical and the Contract departments of Seajacks. In addition they also assisted in the mobilization and the supply of required materials. Seajacks is a regular client at Shipdock Amsterdam, also part of Damen Shiprepair & Conversion.
