Abstract : Progress on the building of AGOR 28, oceanographic research vessel Sally Ride. Work continues on initial outfitting lists for Sally Ride and NS5 Hierarchy. NCE was on site testing the noise levels various exhaust pipe configurations. For each test all four engines were running and shore power was secured. A full report will be provided by NCE. The take-away is that the expected result of a 6-db drop when the exhaust pipes were cut off below the stacks coaming was not achieved. The floating dry dock is not certified so the December dry docking has been canceled. Divers should do hull and prop cleaning prior to builders trials. Reports from Armstrong indicate that the steering system hydraulics over heat during DP operations. There are also reports that while in tropical conditions and while in auto pilot, the hydraulic oil temps are warmer than expected. The OEM recommends a normal maximum operating temperature of 125-degrees F. A cooler may be necessary to correct this issue. Reports from Armstrong indicate that the Uncontaminated/Incubator sea water systems lose suction when the sea chest opening comes out of the water. Sea chest may require relocation to a position aft and/or further below the waterline. The anti-fouling paint has failed on the Ride due to an application error. The yard will correct this issue during a planned docking prior to Builder s Trials. With the dry docking cancelled the paint repairs will most likely be during Phase III if it is occurs at DCI.
