Drydocks World Repairs NDC's Al Ghweifat Crane Vessel

The 165 ft x 140 ft x 15 ft self-elevated crane vessel has undergone extensive maintenance related repair and refurbishment. Extensive maintenance was performed on the three Truss-type 260 feet long legs, including the spud can, which will enable the vessel to attain peak performance at 157 feet of water.

Besides external inspection, blasting and painting of the legs, hull, deck, accommodation and tanks were carried out. Leg guides were inspected, replaced and painted.

Around 160 tonnes of steel was renewed. The 7 ft 7 inch high by 25 feet diameter spud cans and pumping equipment were surveyed for maintenance. Five-yearly inspection of two 70-tonne side cranes resulted in appropriate modification to install man riding units. In addition, the Searex Omnilift 210-tonne crane was dismantled, inspected and overhauled.

An Aluminum heli-deck was supplied and installed. Designed to accommodate BELL 214/212 ST helicopters and approved by Abu Dhabi Aviation Authority, the steel substructure and landing points were fabricated and designed on the vessel.

The existing firefighting system was modified to allow landing of helicopters while in afloat mode. Additional booster pumps were provided for FiFi system and extra lines fabricated from sea chests to the new heli-deck and a new heliport has been added. The capacity of the submersible pumps and the size of hose reels were increased to suit the Standards of Offshore Helicopter Landing Areas, CAP437.

The accommodation was completely refurbished, AC was repaired and upgraded, pipes were replaced, bow and stern thrusters overhauled and tail shafts were removed and re-aligned with gear boxes. The shipyard built and manufactured the upper surface of the vessel consisting of two decks (including radio room and bridge), senior level deck and all stair cases.

The repair and maintenance carried out by Drydocks World for NDC has increased over the years as the company received four orders late last year to add to the eight projects completed prior to 2013.
