TABLE OF CONTENTS All anchors and chain cables are to be tested at establishments and on machines recognised by the committee and under the supervision of Lloyds Rules'(LR's) Surveyors or other Officers recognised by the committee. Test certificates showing particulars of weights of anchors or size and weight of cable and of the test loads applied are to be furnished and placed on board ship.
Water depth to be at least 30m. Ship forward speed to be at or very near to zero. Tests are made to examine the brake control as anchor is lowered to 30 m water depth. Single and double hoists are made, from 30m water depth until clear of the water. Measurements are made of the water depth, length of chain below water level, chain speed (at least 9m/min) of hoist, ammeter reading and hydraulic pressure. These hoists are to be made when ship speed is zero.
A windlass of sufficient power and suitable for the size of the anchor chain is to be fitted to the ship. During trials on board ship, the windlass is shown to be capable of the following:
for all specified design anchorage depths: raising the anchor from a depth of 82.5 to 27.5 m at a mean speed of 9 m/min;
for specified design anchorage depths greater than 82.5 m: in addition to (a), raising the anchor from the specified design anchorage depth to a depth...
