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 will be performing noise testing on Ride in the near term. Baseline testing will be done alongside prior to any changes. The baffles will then be installed at the ends of the exhaust pipes and tested. Next the exhaust pipes will be cut just below the coaming of the stack, followed by NCE taking another round of noise level readings. Lastly, the stacks will be reinstalled with their openings directed 45-degrees to port, as done on Armstrong. A final set of noise levels will be taken. During commissioning of the controls for the CTD handling device by Systems Interface, the rod sensor to the main boom was found have failed. Allied has made repairs and the cylinder should be on site shortly to be reinstalled and tested. Anchor handling mod on Armstrong port side did not appear to work. Chain jumped the wildcat three different times while lowering the port anchor under power. Metal grating around Armstrong bridge is clipped down with galvanized 20 bolts tapped into the aluminum framing below. This will make a path for galvanic corrosion and likely rot out the aluminum. I see the same issue with the mounting of antennas clamped/bolted atop the pilot house and the mast. In most cases the hardware is stainless steel but without rubber or nylon insulation.
