Course offered at International Maritime College Oman

Lesson 21: Mooring Winch and Anchor Windlass (Deck Officer)

Focuses on the operation and maintenance of mooring winches and anchor windlasses
Key objective is to discuss the operation and maintenance of the winches and windlasses to ensure safe vessel operation in port.

Objectives

Students will be able to discuss the operation of mooring winches and anchor windlasses.
Students will be able to take the correct action and perform maintenance related to the safe operation of a mooring and windlass.

Important Points for Ship's Mooring Equipment Maintenance

Proper operation of mooring equipment is crucial for safe vessel operation in port.
(Singh, 2019)

Components of a Mooring System

Warping head
Drum
Bollards
Eyes to connect stoppers
Guide roller
Center lead
Leadway
Head line
Forward spring
(Korlaske, n.d.)

Components of an Anchor Windlass

Chain stopper
Anchor chain
Hawse pipe
Riding power
Gear
Drum (storage)
Dog clutch
Shaft
Clutch lever
Brake for winch
Drum (wrapping)
(Menon, 2020)

Brake Lining

Maintenance is critical for proper windlass and mooring operation.
(Dellner Bubenzer, n.d.)

Checks Prior Mooring

Check for physical damage to the mooring mechanism
Check controls and linkages
Ensure levers are well-oiled and greased
Check levers for smooth operation
Inspect brake drums and linings for dryness and cleanliness
Inspect gear hydraulic oil.
(Singh, 2019) ; (Menon, 2020)

Mooring Prevention Check and Maintenance

Walkway should be clean and free of obstructions and oil
Inspect gratings and brackets for corrosion and rust.
Steel wire mooring ropes should be greased and lubricated
Check grease nipples for rust and salt.
Regular maintenance and painting.
Inspect drums and check for signs of corrosion or wear.
(Singh, 2019); (Menon, 2020)

Important Check on Brake Lining

Check the brake linings for wear and tear; replace if necessary
Check for oil (very difficult to remove, need to replace the lining.)
Check and clean any heavy rust.
Remove moisture; apply the brake smoothly while running.
(Singh, 2019)

Driven Methods and Windlass Important Parts

Electrical motors and hydraulic motor and pump
Main shaft
Driving shaft (connect to motor)
Gear and pinion
Inspection cover
Drums
Brake
Coupling
Clutch
Chain wheel
Speed control valves block.
(Menon, 2020)

Safety Important Points while Operating Anchor Windlass

Put the mooring winch brake "on" and the clutch in disengage position before operation
Drop and stop the anchor in every ½ shackle
In rough weather, loosen the anchor chain tension while heaving up using engines to avoid excessive load on the windlass
(Bhanawat, 2021); (Menon, 2020)
Grease and lubricate the bearings weekly
Inspect the condition of the brake lining monthly.
Inspect piping and valves
Nevet leave a winch in gear with the winch band brake "on".
(Bhanawat, 2021)

Immediate Action in Case of Brake Lining Damage

Informing the master
Planning to replace the defective brake lining
Order for supply of new brake lining
Check the other fore and aft windlasses
Secure the aft port windlass with extra lashing instead of brake
Measure the size of the brake lining and the bolts/nuts.
(Bhanawat, 2021)

Important Points During Brake Lining Replacement

Secure the chain and anchor with extra lashings
Carry out the job in calm waters.
Ensure all connecting pins move smoothly
Clean and grease the pins.
Mark the position of the brake screw-down lever and brake bands
Check the condition of the supporting plate surface.
(Bhanawat, 2021)
