Anchor windlass trials


Each windlass shall be tested under working conditions after installation on-board to demonstrate satisfactory operation. Each unit is to be independently tested for braking, clutch functioning, lowering and hoisting of chain cable and anchor, proper riding of the chain over the chain lifter, proper transit of the chain through the hawse pipe and the chain pipe, and effective proper stowage of the chain and the anchor.

The mean hoisting speed is to be measured and verified, of each anchor and at least with 82.5m length of chain submerged and hanging free. The braking capacity is to be tested by intermittent paying out and holding the chain cable by means of the brake application.
