MacGREGOR Plimsoll Deck Machinery Operation & Maintenance Manual – CM/P4621 Issue A

This Operation & Maintenance Manual from MacGREGOR Plimsoll Pte Ltd documents the complete deck machinery installation aboard the 80T BP Rotor Tug, covering the hydraulic towing winch, the hydraulic anchor windlass/towing winch, and the electro-hydraulic power pack that drives them. Issued as reference CM/P4621 Issue A, with the companion CM/P4622 Issue A for the second hull also included in this file, the manual walks through system descriptions, control functions, operating procedures, LTMS calibration routines, lubrication and brake maintenance schedules, and full hydraulic power pack troubleshooting. Exploded component views and the hydraulic schematic are included, making it a working reference for crew and shore technicians responsible for keeping these winches operational.

Read as a whole, this MacGREGOR Plimsoll deck machinery manual gives a technician a complete route through the equipment: what each winch is rated for, how the controls and LTMS are calibrated, how to operate the winch, gypsy, and anchor safely, how to keep the brake and lubrication systems in specification, and how to diagnose hydraulic power pack faults down to pump cavitation, aeration, and valve performance. Exploded motor and pump views, together with the hydraulic schematic, mean the book stays useful even when a job moves from routine servicing into component-level repair.

What This Manual Covers in Detail

The hydraulic towing winch section (PC-HTW/SD-20/180) documents a 700 m x 52 mm SWR drum capacity across 10 layers, rated at 20 T x 10 m/min on the first layer and 5 T x 40 m/min at high speed, with a 180 T static brake holding capacity. The anchor windlass/towing winch section (PC-HATW/GDG-22-20/120) covers 22 mm stud-link U2 chain handling, a 2.5 T x 0-10 m/min duty pull, and a 120 T static brake hold on the winch drum. Both units run through HMC270 and HPC-200 radial piston motors respectively, with gear ratios and pinion data printed for each. The electro-hydraulic power pack is documented at 2 x 30 kW (70 LPM at 270 bar) plus 1 x 7.5 kW pilot duty (95 LPM at 10 bar and 35 LPM at 60 bar) on a 415 V three-phase supply. Calibration of the length and tension monitoring screen, pressure calibration values, speed factors, and alarm limits are all laid out step by step, along with the brake set adjustment sequence and lining wear-in procedure including the 200 degree C temperature limit.

Brake and Hydraulic Maintenance Guidance

Brake maintenance is treated in its own chapter with both hydraulic and manual variants. The hydraulic brake lining replacement procedure walks through paying in the wire rope, isolating the hydraulic system, using the quick release adjuster, removing the adjuster pins, lifting the brake bands, inspecting the inner band surface, and riveting or bolting the new lining. Brake set adjustment covers the vertical type with thread length targets and gap verification. The wear-out procedure specifies 45 minutes of drum rotation with a dragging brake while monitoring flange temperature, and rust removal steps explain the pay-in direction and crosswise finishing strokes to avoid surface scratching. The power pack chapters add flushing requirements to NAS 1638 Class 8 or ISO 4406 17/14, filter change schedules from 10 micron to 5 micron, and a full contamination reference table comparing NAS, ISO, CETOP, MIL, and SAE classes.

Troubleshooting and System Testing

A dedicated troubleshooting section covers system no-start conditions, equipment not working, equipment malfunction, mechanical noise, bearing failures, and overheating, each with causes and remedies. Flow charts for basic hydraulic power troubleshooting, pump cavitation, and aeration of fluid break down fault, cause, and remedy in structured form. Directional control valve and pressure relief valve system tests are diagrammed with gauge insertion points and decision paths. The safety procedure for shutting down machines lists the sequence from lowering suspended loads through pressure exhaust, accumulator drain, intensifier discharge, and electrical isolation. A gear oil selection table spans ambient temperatures from -20 degrees C to +65 degrees C.

Reference Drawings and Parts

The manual closes with a reference drawing index covering hydraulic towing winch general arrangements, sectional arrangements, brake assemblies, clutch lever assemblies, spooling gear assemblies, hydraulic schematics and piping layouts, local control stands, electrical cable layouts, starter panel layouts, PLC input/output controls, and electrical connection diagrams. Exploded parts views for the HMC270 Series 70 motor and the 2520V pump include itemised code, description, quantity, and part number listings, along with recommended spare parts for hydraulic, electrical, and mechanical components.

Why This Manual Matters for the 80T BP Rotor Tug

Deck machinery on a rotor tug operates under continuous load, saltwater exposure, and heavy duty cycles. The MacGREGOR Plimsoll towing winch and anchor windlass are safety-critical systems, and the manual gives technicians the exact procedures, torque values, calibration limits, and alarm thresholds that keep them within specification. Without it, brake adjustment and hydraulic calibration become guesswork, and troubleshooting a pump or directional valve fault costs time and unnecessary parts. The exploded views and part numbers let a workshop identify and order the exact component before the winch goes out of service. Whether the job is a routine lubrication round, a brake lining change, a pressure calibration check on the LTMS, or diagnosing a cavitating main pump, this operation and maintenance manual covers the job from start to finish.
