Marine deck equipment is one of the most vital machinery that ensures large ocean ships are running smooth. Large cargo ships are the most vital means of transport that enables the availability of the products of various countries in one place. Mooring is one of the most important functions that are performed regularly in these large ships as they move from port to port and only efficient marine deck machinery can ensure smooth moorings.
A winch plays a vital role in ensuring the mooring process is efficiently undertaken. It is a device that handles the reeling in or letting out of ropes or wires that is used for anchoring or mooring process. It is also used to adjust the tension of the rope so that the boat or the ship does not relocate from the position. Earlier, all this was done by hand but today electric or hydraulic motor fitted winches are available that can be controlled from a room.
Winches can be spotted at the front side and after decks on both sides of the ship as it is commonly used for mooring. Today hydraulic winches are not so popular with sailors because the risk of the oil leak and malfunctioning is higher in these kids of winches. Control, power, and safety are the major concern that is concentrated by the manufacturers of the winches let it be the hydraulic or electric motor. Technology has evolved to such a level that today big winches are manufactured that can be controlled by a single man.
This is also one of the most important devices that are installed on the decks very near to winches that help in lowering or raising the anchor. To prevent the slippage of the chain while anchoring or raising the anchor the bow or the chain stopper is used with the windlass. This device is usually driven by the motor and to make the whole operation smooth and efficient, it is provided with clutch and brake that functions similar to the ones we find in automobiles.
The process of anchoring is very tedious and should be done with utmost care, the anchor is lowered slowly in controlled phases to avoid any kind of damage and to attain complete control of the process. Brakes are essential to prevent the overrunning of the chain that can cause damage to the equipment.
Chain stopper or bow plays a crucial role in anchoring as it stops the chain from further movement to ensure safety. The speed and the direction of the ship also play a crucial role in the success of anchoring. The chain stopper or bow also work like brakes and lessen the strain on the brake of the windlass. During an uncontrolled situation windlass, brake and clutch may not be enough to control the anchor and this is the time when chain stopper comes in handy.
There are many other marine deck machinery that helps in the smooth voyage of a ship, but when it comes to mooring these two equipment are most important.
