Mooring, Basic training. General Description. Learn objectives.
The purpose of mooring system is to position the vessel during the cargo operations. Mooring lines can be used to assist heaving the vessel along side a berth and also to assist in un-berthing. The mooring system has to maintain the vessel's position alongside against forces that tries to move it and witch can be caused by: Wind Current Waves and Swell Surge due to closely passing vessels Change in freeboard Changing of under keel clearance.
From head to toes PPE and why: Hard Hat (Helmet) with Chin Strap Protects the head.
Commonly wires and ropes used onboard CMA-CGM vessels.
Description of equipment MOORING STATION (example).
Winches are used to tension/pull the lines. The axel is horizontal and are used for strong, continuous pulls. Elements shown in the image: Winch reel (3 sections) Tension drum used to keep constant tension, in force Storage drum (larger one) used to store the rope Drum end used to maneuver ropes manually Winch brake the manual brake Clutch used to enable/disable the Storage and Tension Drum Electric motor (includes an electrical brake) Control pedestal.
Description of equipment CAPSTANS. Capstans are used to tension/pull the lines. The axel is vertical and are used for short usage, like picking up the tug’s line. Elements in the image: Capstan drum Controls Electric engine Capstans can be built either electric (this case), air driven or hydraulic driven type..
Description of equipment BOLLARDS. Important element on the mooring decks are the Bollards. They are used to secure the ropes on..
Description of equipment. Rope STOPPERS Depending on the material the rope is made of there are different way of using a stopper for: Fixing or passing a stopper for natural fiber lines Fixing or passing a stopper for synthetic fiber lines Green is the Rope to secure Red and Blue are the stoppers used..
Typical mooring arrangements FAIRLEADS. Open Type roller.
Typical mooring arrangements CHOCK The Chocks are used to pass the ropes out, but for those situations that do not involve the movement of the rope after the line is secured because it involves elevated friction..
Common mooring situations 4 lines + 2 springs (Forward & Aft).
Tasks performed by Deck-Hand. A deck-hand seafarer has to be able to perform the following tasks while working on a mooring station: Execute the orders given by the officer in charge of the mooring operation. Easily identify the side of the vessel and the ropes concerned in the operation. Be able to identify dangers that might concern him/her or one of his/her coworkers. Be aware of his/her position on the mooring station, taking into consideration the Danger Zones. He/She should be able to quickly identify the tools or the needs of a situation to be solved. He/She should know how to make fast a line and how to use stoppers. Do not take initiative in doing something without officers direct approval. He/She should be able to help the Bosun/AB in preparing the mooring station for arrival (mooring) under officer’s supervision. He/She should be able to help the Bosun/AB in preparing the mooring station for departure (de-mooring) under officer’s supervision..

Always wear the correct personal protective equipment (PPE), which is an important part of proper preparation considering that PPE is the last line of defence. Always consider whether you are in a snap back zone and never stand on either an open line or a closed bight of line. Keep an eye out for all members of the team. If you think they are in an unsafe position, alert them. All operations need to be carried out calmly without rushing about. Rushing leads to slips, trips and falls. Never lose sight of what is going on around you and have an escape route from any likely danger (that is, avoid being trapped against the bulwark or other obstacle when a line parts). Always put an eye onto a bollard or bitts by holding the eye either on its side or by a messenger line to avoid getting fingers trapped against the bollard if the line suddenly snaps tight. Never heave blindly on a line when no one is watching what is happening at the other end. Never try to be heroic by jumping onto a line that is clearly running over the side and out of control as you are likely to go overboard with it. Never run more than one line around a fairlead sheave as the lines chafe through quicklier and the sheave is really only strong enough to take the load of a single line under tension. Never use any equipment that is obviously faulty. If you notice damage, then it should be reported and an alternative arrangement for the mooring line used. Never let go of a mooring line under heavy load without determining first why the load is so heavy and then taking the proper precautions if it must be let go. Take your time.
