This Statement of Work details requirements for refurbishing Ballast Valve Remote Operator System Hydraulic Pumps, motors, and valves on the USNS Comfort (TAH 20) under contract N3220524C4073. The work involves servicing two Vickers hydraulic pumps, two General Electric 20HP electric motors, and one valve block assembly containing multiple Vickers valves located in the Auxiliary Machinery Access.

The contractor must work on one pump/motor set at a time, ensuring the first set is operational before removing the second. The scope includes disassembly, inspection, repair, and testing of components, with up to 80 hours and $5,000 in materials allocated for pump repairs and 20 hours and $2,500 for valve repairs. Two approved vendors are specified: Global Hydraulics Inc. and Hyval Corporation. The work requires ABS/USCG oversight and testing approval, with detailed documentation requirements for condition reports and test results. The ship's crew will handle removal and shipping of components to the contractor's facility, with valve work to be performed at Naval Base Norfolk VA.
