Key Technical Specifications

The CD20A mooring winch offers a nominal towing power of 200 kN on the first layer, with maximum towing power of at least 1.5× nominal. The automatic operation system provides three towing power ranges: 20÷60% QZN (40÷120 kN), 50÷90% QZN (100÷180 kN), and 80÷120% QZN (160÷240 kN). Speed on the mooring drum ranges from 18 m/min nominal to 37 m/min at high speed for B-series, and 15 m/min to 30 m/min for C-series. The mooring line drum capacity accommodates 200 m of synthetic rope with 60 mm diameter.

The PK87 anchor attachment unit handles 87 mm chain caliber with a nominal towing power of 360 kN, maximum towing power of at least 2× nominal, and a braking force of 2476 kN. Chain heave-up speed is at minimum 9.17 m/min, with a cable lifter pitch diameter of 1107 mm.

What This Manual Provides

This Operation and Maintenance Documentation gives technicians and operators everything needed to safely operate, maintain, troubleshoot, and repair the TOWIMOR CD20A mooring winch and PK87 anchor attachment unit. The manual covers the complete mechanical structure from the three-step transmission gear and band brakes to the sliding claw clutch mechanism and cable lifter assembly. The electrical section provides deep coverage of the PLC-controlled drive system, including the Moeller PS4-201-MM1 programmable controller with extension modules, all input/output signal assignments, fault diagnosis through LED status indicators, and full wiring diagrams.

Detailed procedures guide the reader through manual and automatic mooring operations, anchor handling from casting to retrieval, torque adjustment of the slipping clutch, brake wear adjustment, and proper lubrication schedules with specific grease point locations illustrated. The fault tables help diagnose and resolve common mechanical and electrical issues without guesswork. The manual includes separate malfunction tables for the mooring winch and anchor attachment unit, covering issues such as noisy gear transmission operation, excessive bearing overheating, braking difficulties, grease leakage, and creaking slide bearings.

The electrical fault tables address motor operation issues at different speeds, automatic operation failures, and overload conditions. Each fault entry provides the likely cause and the recommended remedy, making this Towimor CD20A PK87 manual an invaluable diagnostic tool for both routine maintenance and emergency troubleshooting.

Maintenance and Inspection Coverage

This Towimor CD20A PK87 manual provides a complete maintenance framework with three tiers of inspection. Routine checks are performed before each operation and after finishing work, covering rope condition, construction mechanisms, brake clearance, and winch operation uniformity. Periodical inspections occur every 40 hours of work or every three months (whichever comes first) for the mooring winch, and every 48 working hours or every three months for the anchor attachment unit. Four-year inspections involve comprehensive examination of rolling bearings, sliding bearings, band brakes, and steel construction.

The maintenance section includes detailed greasing instructions with specific grease point locations for both the mooring winch (grease points S1 through S16) and the anchor attachment unit (grease points S1 through S16), each with recommended greasing intervals. The gearbox oil fill and drain procedures are illustrated, with the first oil change due after three months of operation and subsequent changes at least annually.

Electrical System Documentation

The electrical equipment section of this Towimor CD20A PK87 manual covers the NEPN016T13F and NEPN016T22F drive systems in exceptional detail. The manual explains the manual control system with three-step speed operation, automatic control for maintaining constant towing power, and impulse control for one-man operation of clutch engagement. The protection and signalling systems are fully documented, including motor temperature control through thermistor relays, brake current checks, automatic operation monitoring, and the various signalling lamps (H1 through H6) with their meanings and fault indications.

The towing power measurement system using tensometric transducers and the WZMD amplifier is described with calibration procedures. The chain length measurement system with inductive sensors and the A0 programmable controller is explained with input/output assignments and troubleshooting guidance. Complete electrical diagrams, wiring diagrams, and circuit diagrams are included for both three-stand and two-stand control configurations.
