Keppel Verolme started 2012 dry docking the largest crane vessel in the world - Heerema’s Thialf. Earlier this spring, Thialf had swapped places with Saipem’s semi-submersible drilling rig Scarabeo 6 in the yard’s mammoth dry dock. With 2 cranes, the Thialf has an individual lifting capacity of 7.100 tons, and is actually classed as a Deep Water Construction Vessel (DCV) since she is also frequently contracted for installation works in deep water areas.
repair and maintenance works were concurrently executed. When completed, Thialf is expected to be able to operate for another 20 years.
Work on the rig is centered on the upgrading of its drilling capabilities to a water depth of 1200 meters. This includes prefabricating and installing sponsons and deck extensions as well as installing traction winches, cable spooling winches and double riser tensioners.
The dry docking was Thialf’s first since her delivery in 1985. She underwent a thorough inspection and maintenance program in the first quarter of 2012. Work comprised the application of a new painting program on the vessel’s floaters, columns and bracings while
Another major project in the yard is the extensive upgrade, repair, and maintenance of the semisubmersible drilling rig, Scarabeo 6, for repeat customer Saipem. The vessel which arrived in spring 2012 will be here for a period of approximately six months.
