ANCHORING SUPERVISION/PREPARATION
Preparations for anchoring must be supervised by a certificated deck officer. Anchor work is only to be assigned to capable crew members.
Before dropping anchor, a check is to be made ensuring that there are no small craft or obstacles under the bow.Chart to be checked for underwater obstructions, pipelines, cables, deposit of water, etc.
The man operating the brake and others in the vicinity must wear safety goggles and helmets to avoid the risk of injury from dirt, rust particles and debris thrown off as the chain runs out.
The officer in charge of anchoring is to keep the bridge informed of the number of shackles of cable out and the direction the chain is leading.

The members of the crew engaged in stowing an anchor cable in the locker must be in a protected position and as far as practicable keep in constant communication with the windlass operator.
Importance is to be given to maintenance and inspection of the windlass, especially on the brake linings, the bolts, lubrication and fittings. It is advisable, whenever possible, to check the securing of the last link in the chain.
ANCHORING - POINTS TO CONSIDER
A)Has an anchoring plan been prepared taking into account?
- Speed reduction in ample time.
- Direction/strength of wind, current.
- Tidal stream when manoeuvring at low speeds.
- Need for adequate sea room particularly to seaward.
- Piping and cables at the sea bed
- Which anchor to be used: port or starboard
- Condition of the vessels in the vicinity; laden or ballast
- Lengths overall of vessels in the vicinity
B)Have the following been informed of the time of standby for anchoring?
- The Master.
- The engine room.
- The anchor party.
C)Has the following equipment been tested and found ready for use?
- Telegraph tested.
- Engine tested astern prior to arrival at anchoring point.
- Windlass tested prior to arrival at anchoring point and both anchors ready.
- Lights/shapes.
- Sound signalling apparatus.
- Bridge – foc’s’le communications established prior to arriving at anchorage.
EMERGENCY ANCHORING
Should apply to most emergencies particularly in pilotage waters where the anchors should be ready for immediate use.
There are exceptions to having anchors ready such as when mooring to an SBM or other facility where port regulations may require anchors to be secured.
This exception apart and where clear from submarine pipelines and cables, anchors should be run out until sufficient cable is deployed to enable the anchors to hold. In this case both cables will be leading astern throughout the operation and both will be subject to bad nips.

This means however that the hawse pipe lips will be relieving the strain upon the windlass. Furthermore both cables will be taking equal strain. A small/light ship will be brought up quite rapidly with two anchors used in this fashion. Needless to say it will be wise to subsequently have a survey made of all the anchoring equipment.
