3.12 If the winch is electric, then provide either a two speed electrical winch motor control system or a variable speed control system.

3.13 If the winch is hydraulic, then provide the HPU with marine industry standard vane pump, sump strainer, return filter with bypass valves, flexible drive coupling set and stainless steel reservoir with access plate for cleaning. Include stainless steel isolation valves and desiccant filter type breather vents. Under no-flow conditions, ensure the vent prevents the passage of air, and minimize vented contamination. Ensure the reservoir will not spill fluid when the ship rolls 45 degrees. Include hydraulic pressure gages for all supply pressure piping and tubing systems including supply side of the HPU. Provide all hydraulic hoses with Grade 316 stainless steel fittings. Ensure maximum hose length is less than 30 inches. Pressure test all hoses and attach a permanent metal weather resistant tag engraved or embossed with ¼ inch high letters with the part number, "Tested 150% WP" and Test Date [DD/MM/YY]. Provide a list of hoses with tag numbers on a spread sheet which identifies system design pressure, hose test pressure, hose length, description, and both end fitting OEM part numbers.

3.14 Operates with a dead man brake and a centrifugal brake to control speed of lowering. Include a non-rotating crank handle (in lowering condition). Include automatic hollow pinion couplings. Ensure all mechanical parts operate with gearing running in an oil bath.
