Ship equipment varies according to different purposes of vessels and usually concerns the equipment for the rudder and anchor as well as for the life-saving cargo-lifting and mooring. 1. The Rudder Equipment The rudder equipment is a plant to maneuverability by which a vessel is able to ensure Fig. 10. 1 Anchor equipment thiết bị neo 1-Anchor neo 2-hawse pipe ống neo 3-chain cable xích 4-anchor windlass tời neo 5-chain stopper cái chặn xích 6-chain pipe ống xích 7-mooring pipe ống dây chằng buộc 8-fairlead sô ma dẫn dây 9-wire reel tang quấn cáp 10-bollard cột buộc dây vessel sail along a given course alter the course or perform a turning motion as we mentioned in the chapters of seakeeping performances. The main components of the rudder equipment include steering wheel drive mechanism steering gear steering mechanism rudder rudder stock rudder carrier rudder stopper and rudder angle indicator. As far as the drive mechanism steering gear and steering mechanism are concerned a choice may be made among three different operation modi namely mechanical hydraulic or electrical-driven. Moreover an automatic steering gear has already found wide application at the present time which joins the traditional steering gear to an electrical compass and calibrates course errors automatically during voyage. 2. The Anchor Equipment Vessels in harbour will if not moored drift away due to the external forces of wind current and wave impact and so forth. The anchor equipment acts the role of a mooring unit to stop a vessel from drifting and under certain particular conditions it can be applied to handle a vessel as some auxiliary means as well. The anchor equipment is made up of anchor anchor chain cable chain hawsepipe chain stopper chain pipe chain locker anchor windlass chain windlass and capstan windlass anchor winch .
