When a gantry crane is required for handling heavy lifts (see definition of heavy lift below), and the gantry crane is being used on another vessel with buckets, magnets, or any use other than heavy lifts, the following procedure will be followed:
On notice given the agent of the vessel on which gantry crane(s) is (are) being used prior to 1600 hours, the crane(s) may be withdrawn for the handling of such lifts on the following or later day. This withdrawal for the heavy lifts shall commence at either 0800, 1000, 1300, or 1900 hours. Promptly upon completion of heavy lift use, the gantry crane(s) will be returned to the first vessel.
Definition of Heavy Lift: Any lift not capable of being handled with vessel's gear.
