The winch is government-furnished property currently installed on U.S. Coast Guard vessels including the 175 WLM, 225 WLB, and 210 WMEC class cutters. The contractor must assume full responsibility for the safety and care of the winch while in possession and report any discrepancies immediately to the Coast Guard Contracting Officer.

The contract requires comprehensive disassembly, inspection, and refurbishment of the winch with detailed documentation including condition reports, part lists with nomenclature and costs, and repair quotes submitted separately by serial number. Specific work includes conversion to Parker ORS series O-Ring seals, replacement of all worn components with new original equipment parts, surface preparation via blast cleaning to achieve 1.5-2.5 anchor surface profile, painting with a polysiloxane system (zinc-rich primer, two polysiloxane coats in SPAR color 10371), and complete reassembly with calibrated testing equipment. The contractor must conduct extensive performance testing including no-load, dynamic overload, static overload/brake, rated load, and constant tension tests, all documented in detailed test reports with specific pressure and speed parameters. Additional requirements include paint data sheets, certification plates affixed to tested winches, mandatory quality assurance inspections with seven working days' notice, compliance with referenced standards (SAE, ISO, MIL-STD, ANSI/ASQC), and proper preservation and packaging for shipment. The estimated cost for the overhaul is $48,906.72, with Allied Systems Company Inc. identified as the recommended source.
