Calculating the Size of the Mooring rope/chain

-

The Mooring Lines (or cables) used to secure a ship at a berth. Mooring lines should be arranged as symmetrically as possible about the midship point of the ship. The Calculation of the size of the mooring rope is done same as the anchor size calculation. 

The step of Mooring line calculation are as follows

  1.  Calculation of the Vessel or ship displacement in fresh water and sea water by the formula available. For formulas click here.
  2. Calculation of Equipment Number by formulas.for formulas click here.
  3. From Equipment Number, find out the the specification of Mooring rope /chain from the table. For table click here.

From the Mooring line calculation, we find out the following:-

  • Mooring Lines
    • Number
    • Length of each mooring ropes (m)
    • Minimum breaking strength (KN)

 The Specification from one company are as follows

Introduction to Mooring Line

-

The mooring refers to any permanent structure to which a vessel/ship may be secured. Examples include quays, wharfs, jetties, piers, anchor buoys, and mooring buoys. A ship is secured to a mooring to forestall free movement of the ship on the water. An anchor mooring fixes a vessel's position relative to a point on the bottom of a waterway without connecting the vessel to shore. As a verb, mooring refers to the act of attaching a vessel to a mooring. Mooring is often accomplished using thick ropes called mooring lines or hawsers. The lines are fixed to deck fittings on the vessel at one end and to fittings such as bollards, rings, and cleats on the other end. Mooring requires cooperation between people on a pier and on a vessel. Heavy mooring lines are often passed from larger vessels to people on a mooring by smaller, weighted heaving lines. Once a mooring line is attached to a bollard, it is pulled tight. Large ships generally tighten their mooring lines using heavy machin

Introduction to Towline

-

A tow line is used with a tug (tugboat or towboat) which is a type of vessel that maneuvers other vessels by pushing or pulling them either by direct contact or by means of a tow line. Tugs typically move vessels that either are restricted in their ability to maneuver on their own, such as ships in a crowded harbor or a narrow canal, or those that cannot move by themselves, such as barges, disabled ships, log rafts, or oil platforms. A tow line is the essential link between tug and ship. This applies to tugs operating alongside a vessel in the push-pull mode as well as to towing tugs fastened with a tow line to the bow or stern of a ship, also called `tugs towing on a line‟. Basic towline requirements A towline must fulfil two basic functions, firstly to function as the load-carrying link between tug and ship and secondly to cope with the dynamic loads resulting from the relative motion between tug and ship. This leads to the following basic requirements for towlines for harbo

Component of Ship Anchor Windlass

-
Image
The windlass machinery is combined with the forward mooring winch as one unit. The main winch consists of a double reduction gearing arrangement to produce a large torque. A brake is provided for control and a windlass is usually powered by an electric or hydraulic motor operating via a gear train. An ideal windlass assembly consists of a cable lifter, mooring drum and a warp end. All these are rotating equipment that work together for the anchoring process. The cable lifter has cable shaped snugs that are used to grip the anchor cable on the drum. The cable from the cable lifter goes around a mooring drum, which guides the cables by paying out or letting go of the mooring wires. A warp end is used to hold the cable at the desired position and is always driven in association with the mooring drum for efficient carrying out of the warping duties. Although all these units work together, they can also be individually controlled. A dog clutch is used to separately engage or diseng
