The Contractor shall submit a CIR for the inspections listed in the following paragraph(s): None. 3.1.2 Tech Rep.� The Contractor shall provide the services of an OEM authorized/ licensed Tech Rep for the Steering System Hydraulic Power Units to accomplish the following on site: ����������� Provide manufacturer's proprietary system/ equipment information, software, and tools. ����������� Assist with and ensure compliance with manufacturer's procedures and standards during disassembly, inspection, repair, modification, calibration, and reassembly of the equipment/system. 3.1.2.1 Ensure the Tech Rep is an OEM Certified Representative for the system/equipment stated above and demonstrated on their r�sum�. 3.1.3 Protective measures. The Contractor shall furnish and install all protective coverings to seal off and protect all non-affected vessel's components, equipment, and spaces near the work area against contamination during the performance of work. Upon completion of work, the Contractor shall remove all installed protective measures, inspect for the presence of contamination, and return all contaminated equipment, components, and spaces to original condition of cleanliness. 3.1.3.1 Protective measures - hydraulic system(s).� The Contractor shall maintain existing hydraulic system cleanliness and take all necessary precautions to prevent the introduction of contaminants into the hydraulic system.� Immediately after disconnecting or removing components from the hydraulic system, the Contractor shall completely seal all openings to the rest of the system using caps for externally threaded connection points, bolt-on blanks, or taped-on discs/covers made of durable plastic or sheet-metal that is no less than 1/16-inch thick. NOTE Plastic bags may be used only when arrangement or configuration prevents the use of the other sealing methods specified above. 3.1.4 Interferences. The Contractor shall handle all interferences in accordance with SFLC Std Spec 0000, paragraph 3.3.5 (Interferences). Known interferences include, but are not limited to the following: ����������� Piping ����������� Hydraulic Oil (approx. 560 gals.) ����������� Overhead ����������� Insulations ����������� Wiring ����������� Ventilation Ducts ����������� Insulation ����������� Pipe hangers/brackets WARNING �Maintain the strictest standards of cleanliness in accordance with MIL-STD-419 while hydraulic system is open.� Hatch opening shall be covered and roped off to prevent a falling hazard to personnel when not in use.� Work on the steering hydraulics is not permitted while any blasting, grinding, welding, etc. is being performed in, or adjacent to, the steering gear space. NOTE NSCs have two separate steering systems, one port and one starboard.� Each system has a dual hydraulic power unit that use hydraulic oil MIL-H-17672, symbol 2135-TH. Each steering system is comprised of one rotary-vane, Rolls Royce Marine Type SR 743 actuator with integral relief valve; one Steering Gear Unit comprised of two Hydraulic Power Units (HPU�s) each of which contains a Bosch-Rexroth variable-delivery, axial-piston type hydraulic pump, a 120-gallon hydraulic oil reservoir, tank suction strainer, 10-micron return filter, level switch and seawater cooled heat exchanger; and a 258 gallon capacity storage tank. Detailed information can be found in CG Tech Pub 7182A and 7193. 3.2 Operational test, initial. The Contractor shall ensure that the rudders are clear of all obstructions.� Align the system for normal operation. Through the test evolution, the Contractor shall have personnel posted at all steering unit repeaters to witness whether the repeaters follow the commands and reflect full stroke at 35 degrees to either side, and stabilize at Zero at the end of each test segment.� Review CG Tech Pub 7193 for full description of the Steering Control System. All rudder angle indicators (manual indicator on actuator, MCMS indicator, local indicator, and remote indicators on bridge) shall be within a 2 degree tolerance throughout range of motion. NOTE Coast Guard personnel will operate all shipboard machinery and equipment. WARNING Special care should be taken not to hold the rudder hard over for more than a few seconds at a time to avoid overheating the system. 3.2.1 Starting with the Starboard Steering Gear, and in the presence of the Coast Guard inspector, place� the 1A HPU on line, with the controller set to �REMOTE�, cycle the rudder from Zero to Port (hard-over), from Port to Starboard (hard-over), from Starboard to Port (hard-over) and from Port to Zero.� On the Port to Starboard and Starboard to Port transitions, record the time from hard over on one side to 30 degrees on the other side (nominal time should be 14.5 seconds or less).� With the rudder at Zero degrees and the HPU running, inspect all hoses, fittings and seals for leakage.� 3.2.2 Set the steering controller to �LOCAL�.� Using the pushbuttons operators on the pump, cycle the rudder from Zero to 15 degrees Port, from 15 degrees Port to 15 degrees Starboard and from 15 degrees Starboard to Zero.� It is not necessary to record times on this evolution � this portion of the test only demonstrates that local control can be achieved.� Record the result as SAT or UNSAT. 3.2.3 Switch to 1B HPU and perform the same tests to complete the Starboard Steering Gear System test. 3.3 Steering actuator piston seal testing.� The Contractor, in the presence of the Coast Guard Inspector, shall conduct a test of the steering actuator piston seals on Starboard actuator. Test in accordance with CG Tech Pub 7182A, Appendix A, paragraph 4.2.1.� Submit a CFR with the test results to the USCG.� Should the readings reflect degradation of the steering actuator piston seals, notify the USCG immediately. 3.6 Hydraulic power unit inspection and repair. 3.6.1 The Contractor shall inspect the pump and motor couplings for any signs of damage, deterioration or defects and submit CFR. 3.6.3 Inspect and adjust all high and low pressure relief valves to their proper settings in accordance with CG Tech Pub 7182A.� Submit a CFR. 3.7 Troubleshoot and repair. The Contractor, in the presence of a Coast Guard representative, shall attempt to determine why the starboard rudder will not respond to local or remote input. The contractor will then attempt to conduct repairs. Submit a CFR. 3.8 Operational test, post repairs. After completion of work and in the presence of the Coast Guard Inspector, the Contractor shall thoroughly test and demonstrate the equipment listed below to be in satisfactory operating condition. Submit a CFR. WARNING Special care should be taken not to hold the rudder hard over for more than a few seconds at a time to avoid overheating the system. 3.8.1 Starting with the Starboard Steering Gear, and in the presence of the Coast Guard inspector, place� the 1A HPU on line, with the controller set to �REMOTE�, cycle the rudder from Zero to Port (hard-over), from Port to Starboard (hard-over), from Starboard to Port (hard-over) and from Port to Zero.� On the Port to Starboard and Starboard to Port transitions, record the time from hard over on one side to 30 degrees on the other side (nominal time should be 14.5 seconds or less).� With the rudder at Zero degrees and the HPU running, inspect all hoses, fittings and seals for leakage.� 3.8.2 Set the steering controller to �LOCAL�.� Using the pushbuttons operators on the pump, cycle the rudder from Zero to 15 degrees Port, from 15 degrees Port to 15 degrees Starboard and from 15 degrees Starboard to Zero.� It is not necessary to record times on this evolution � this portion of the test only demonstrates that local control can be achieved.� Record the result as SAT or UNSAT. 3.8.3 Switch to 1B HPU and perform the same tests to complete the Starboard Steering Gear System test. Submit a CFR. 4.� NOTES 4.1 Data sheets Vendor will provide all labor and parts listed in the Schedule. NAICS Code #336611 applies to this procurement.
