U.S. Report and all related bits, chocks and fairleads were removed from the ship. The new installation and modification included the installation of eight new double split drum Pusnes Maritime 400 HW winches, complete with all related bits and chocks and fairleads, which are all upgraded in size, mostly from 12 to 10 inches. All new hydraulic piping was run from the HPU's to the winches. The major challenge here was main- taining a safe mooring arrangement for the vessel while new installation was accomplished. 120 tons of steel were installed in the unreduced stiffening upgrade of the new mooring arrange- ment. Integrated Bridge Upgrade All existing navigation and communi- cation equipment was removed, cables were pulled back and some reused for new equipment installation. The entire bridge went through a major overhaul. A new IBS console was installed, and two new control consoles were mounted on the port and starboard bridge wings. The main mast was outfitted with two new radars ad wave guides, and all new running lights and antennas. A third radar was mounted on the forward mast. Route planning and plotting monitor and keyboard was a new installation on the chart table. Main Engine Room The propulsion plant, an 1,100 lbs. steam plant, underwent major work, all of the main steam piping and generator steam lines were hydro-tested, and the main condenser, atmospheric condenser, etc., were all hydro-tested and repaired, as needed. The LP turbine covers were lifted and the diaphragms removed, and the LP rotor was removed and unshipped through the ballast tank, and shipped to Houston so that it could be dynamically balanced. Two new Alfa Laval distilling plants and all of the resultant piping and con- trols were installed, as well as new steam and electric hot water heaters. A new Thorlube system was installed to support the lubrication of the new Thor- don strut bearing and stern tube bear- ings. Cargo Tank Work The work items related to the cargo tanks are an addition to the experience of Detyens. As the membrane tanks are fragile, special care and precautions were taken while work was going on in the tanks. A total of three cargo pumps were changed out with their wiring, and the rest of the cargo pump wiring underwent an upgrade, with flexible cryogenic pig- tails installed between all of the cargo pumps and the mineral insulated cable power supply cable, together with nitro- gen purged and pressurized explosion proof connection boxes where the cable exits the cargo tanks and meets the pow- ercable coming from the cargo control house. A new Saab tank radar level indication system was installed, with new still pipes and temperature probes. In the cargo control room, a workstation for the system was installed. Life Boat Modification The existing lifeboat davits were removed and new Schat Harding Davits and boats were installed. A catwalk was fabricated and installed to allow embarkation from the trunk deck instead of the old configuration, where the embarkation took place from the main deck. Fire Main & Sprinkler System The existing firemain line ran under the main deck in the port and starboard. This system was simplified by running a new main line, above deck, from the accommodation to the focs'le, on the port and starboard side slopes from the main lines the system branches off to the relocated fire stations on the trunk deck. In addition to the firemain module, a new Unitor dry powder firefighting sys- tem was installed. Electric Motors Every electric motor on the vessel, varying from forced draft fan motors to fan motors for galley ventilation, was removed and sent to Excel Apparatus for an overhaul, and reinstalled, aligned and hooked up.
