USCGC Midgett Repair of Gas Turbine Blow-In Doorview on SAM.gov

Statement of Work Repair of Gas Turbine Blow-In Door Actuator Mounting Arrangement USCGC MIDGETT (WMSL 757) Purpose . The Contractor must inspect, measure, and fabricate mounting and hardware for new blow-in door pneumatic actuator. Install the hardware, new actuator, and support post-installation testing. Place of Performance . The work must be performed on board the ship at the location detailed below: USCGC MIDGETT (WMSL 757) 400 Sand Island Pkwy Honolulu, HI 96819 Background . USCGC MIDGETT has experienced recurring issues with the gas turbine blow-in door actuator. Ship's force initially replaced the actuator after failure due to a bent shaft. The replaced actuator sticks momentarily, then releases only after a delay, occasionally leading to potentially damaging, jarring opening and closing cycles. Contractor Qualifications . The Contractor must be a certified distributor or approved service partner of Parker Hannafin Corporation (6035 Parkland Boulevard, Cleveland, OH 44124), for the Altair filter system relevant to the National Security Cutter (NSC) blow-in doors. The Contractor must demonstrate experience with pneumatic actuator systems and mechanical door closures by citing specific projects or relevant certifications. CLIN-0001—Inspection and report . The Contractor must inspect and measure the actuator, mountings, system parameters, and door closing hardware in accordance with the requirements of this paragraph. NOTE: equipment will be operated by ship's crew throughout the performance of this scope of work. Conduct an evaluation of the gas turbine blow-in door actuator system by observing operation of the door system over several cycles during an initial operational test. Inspect the existing mounting arrangement and measure relevant dimensions for the actuator and door linkage closing mechanism, and record on a sketch. Verify alignment, bolted connections, linkages, and range of motion are conducive to smooth movement, and identify any points of friction or wear that may be causing binding. If possible, operate the door with the actuator disconnected to further isolate points of binding or friction. Check pneumatic pressure applied to the actuator to ensure it is within manufacturer's recommendations, and that actuator travel is in accordance with the manufacturer's application guidelines for the actuator. Actuator part number is NUMATICS/AVENTICS N23113. Inspect the condition of the new actuator compared with the previous two damaged actuators, and determine root cause for bending and binding of the door lock system. Provide a thorough report of all findings, concluding with a repair recommendation which corrects the cause of the actuator binding by implementing a correction to the dimensions of the actuator bracket, replacing parts of the linkages to the door locking mechanism (if needed), bearings, mounting blocks, or a correcting a problem with the application of the actuator.
