In what circumstances might a vessel need to "slip" her anchor (i.e. let go the anchor and cable rather than recover it normally), and how is this typically done?

A. Slipping is only done for routine anchor maintenance and is never an emergency procedure

B. Slipping the anchor means dragging it along the seabed deliberately to drag the vessel into position

C. Slipping can only be carried out by divers from outside the vessel

D. Slipping may be necessary in an emergency where there is insufficient time or it is unsafe to heave up normally (e.g. urgent need to get underway, fouled anchor, or windlass failure); it is done by releasing the bitter end or disconnecting the cable at a joining shackle, often marking the position with a buoy for possible recovery later

A. Nothing — a test lift can proceed immediately after repairs

B. Testing should wait until cargo operations begin

C. The area within the grab's swing radius should be cleared of personnel before the lift

D. Only the crane operator needs to be aware the lift is happening

A. Who must remain clear of the exclusion zone while the lift takes place

B. The lunch schedule for the deck team

C. Only the weather forecast for the next watch

D. The cargo manifest for the next port
