Damen Shiprepair & Convention has completed repair and renewal works for two of the jack up vessels owned by Seajack at its Shipdock Amsterdam shipyard.

The two jack up sister vessels, Seajacks Leviathan and Seajacks Kraken, have now left the shipyard to work on future assignments.

Earlier, the UK-based Seajacks contracted Damen to refurbish the two vessels with several major and minor adjustments in between North Sea offshore windfarm and oil and gas installation projects.

The repairs for Seajacks Leviathan included the removal of blade racks, after completion of a wind turbine and propeller blade operation.

"Seajacks Leviathan and Seajacks Kraken have now left the shipyard to work on future assignments."

In addition, the Leviathan’s 250m Panamax dock has been added to with a heli deck, made by Damen subsidiary Niron Staal. The lower deck reinforcements have also been deployed to support heavier mounts for future replacement of the lifeboat davits.

For Seajacks Kraken, Shipdock Amsterdam replaced the two lifeboat davit sets and installed Niron Staal prefabricated foundations and four new davits, featuring powerpack, cable, winch, electricity and hydraulic systems. The vessel’s four legs have been restored after an initial joint inspection.

Both jack up vessels have also undergone minor steel work and have been installed with four new satellite dome platforms.

After the completion of repairs, the ships have been subjected to surveyor-assessed test runs, load tests, crane tests and crane hook certification update surveys.
