The MV Union Manta, operated by the URS Towage & Salvage Union, Ltd., is designed to assist offshore lifting platforms in the construction of oil drilling rigs, oil and gas production plants, storage spars, and other related at-sea construction. The vessel was delivered on March 21, 2003, and currently operates throughout the Gulf of Mexico. The vessel is fitted with three large winches used for the handling and positioning of offshore platform mooring anchors. Main power is supplied by two 10,000 hp diesel engines, producing 'pull power' of 205 tons. This makes the Union Manta one of the world's largest and most powerful Anchor-Handling Towing Tugs. In addition to these power features, the vessel is equipped for stand-alone remote operated vehicles (ROV) and survey jobs.
