Chapter SHIPBOARD anchors Ship anchors on the ground Behavior of anchors on the ground A modern ship’s anchor should form a group of requirements relating to the anchoring force of an anchor and its behavior Ship anchors on the ground.
In accordance with this group of requirements, the anchor must have the greatest possible holding capacity at a given mass; it’s easy to quickly enter any grub; to have stability on the pear and keep it at the short end. ” That is, it retains its retaining force when the angle of the anchor canopy is increased by the spindle bracket; It is easy to separate from the grout when lifting. Ship anchors on the ground Part of the requirements relate to the operational quality of anchors and the features of their construction. In accordance with the group of requirements, the anchor should: be convenient for harvesting storage in the marching to have enough mass to overcome the resistance of the chain ellie in recoil.
on, prit koto. Tcu is achieved by turning a certain angle. If the turn exceeds the critical value, it decreases. In this case, the holding force it depends on the magnetometer. The magnitude of the critical angular characteristics of the anchors of different types.
The anchor device is usually located in the bow of the ship. An anchor winch is also installed there. The main part of the winch is a chain sprocket, which allows you to raise the anchor with a chain, and when winding the chain links can fall on the chain sprocket with both sides. In addition to chain sprocket windlass has mooring drums (turecki) for storing mooring ropes. On older types of vessels, the anchor winches were steam-driven. Now use electric or hydraulic drives.
