The 50,000-dwt tanker Sarita, built in Sweden in 1965, was converted during 1975/76 to a crane ship for service in the North Sea under charter to Phillips Petroleum; she is operated jointly by Ugland Rederi and the Houston company Raymond International. The preparatory work, including removal of the bow section, was done by Nymo Mekaniske Verksted, and the vessel was then moved to Bergen, where the main conversion work was done by Bergens Mekaniske Verksteder. The new bow section, in which the 2,000-ton crane is mounted, was partly built by Tangen Vaerft and taken to Bergen for fitting to the hull. The conversion included the extension of the ship's sides by sponsons, for added stability. The main crane is a Model 76 Clyde with a maximum lift of about 2,000 short tons (with the main boom over the bows); it was manufactured in the U.S.A. and assembled at Bergen. The boom rests in a cradle, through the base of which there is access to the cargo holds and workshops; the former centre tanks are now used for equipment and cargo storage, workshops, and an electricity generating station. A 150-ton American Hoist travelling crane has been installed on the main deck, where there is a large working area. The anchor positioning system has eight 10-ton anchors. The main and auxiliary engines have been retained, and have been extensively overhauled. A Schottel bow thruster of 44.5 tons maximum thrust has been added.
