Refurbished Seajacks ready to work

UK-based Seajacks UK ltd assigned the shipyard the task of making various major and minor adjustments to the jack-up vessels in between North Sea offshore windfarm and oil and gas installation contracts.

Seajacks Leviathan first had its blade racks cut loose and removed after completion of a wind turbine and propeller blade operation. Subsequently, the self-propelled jack-up had a heli deck installed in Shipdock’s 250m Panamax dock. This included all related drain and firefighting piping. The help deck had been prefabricated by Niron Staal, which is also a subsidiary of Damen Shiprepair and Conversion and is located on the yard’s premises in Amsterdam.

In addition, below deck reinforcements were installed to support the heavier mounts in view of future replacement of the lifeboat davits.

Shipdock Amsterdam’s work on Seajacks Kraken involved the replacement of the vessel’s two entire lifeboat davit sets. This included installing Niron Staal prefabricated foundations and the four new davits with their powerpack, cable, winch, electricity and hydraulic systems. This was finished off by surveyor-assessed test runs and loads test.

The vessel’s four legs were also restored after an initial joint inspection round with the principal’s inspectors. Repairs involved S690 grade steel.

In addition to crane tests and crane hook certification update surveys, both Seajacks jack-up vessels underwent miscellaneous minor steel work and had four new satellite dome platforms installed.
