ANCHORING EQUIPMENT FOR LARGE VESSELS

The many anchor and cable losses on large vessels have raised questions regarding design, operation, and maintenance of windlasses and anchor equipment. To avoid problems, special attention should be given to hawse pipe and chain locker design, conflict between the general mooring and anchoring systems, chain-stopper design, and securing of stowed anchors. Improved windlass braking systems can minimise the loss of anchors and chain cable. Mooring systems for large vessels are not based on Classification Society rules or those of other authorities, except for parameters such as chain-cable diameter and weight, anchor size, and performance of anchor windlass. Little theoretical work or systematic collection of data are available on the subject, probably due to the rapid increase in ship size over the last 15 years. A lot of accidents and damage can be directly traced to indadequate design. A number of criteria for optimising design layout are listed.
