The Yard has also utilised its specialised engineering and other resources to carry out various repair works on the accommodation of the rig including renewal of floor tiling, ceiling panels, door frames etc.
The shipyard’s Global Offshore Services has also shared its resources and experience in overhauling the cantilever skidding units. The preload tanks were blasted and these and the hull were painted. The Rig’s three cranes were overhauled and extensive machining was carried out. Blasting and painting, replacement of electrical cables, replacement of structural angle bars and beams were other work that was completed on the derrick. Hydro-blasting and painting of legs, overhauling of AC works in accommodation and two generator alternators for engine formed part of the job scope.
