PRODUCTIVITY
Productivity refers to the efficiency of operational "gang" in producing of handling volume of cargoes over a certain period of time (hour, day). Productivity rate is normally expressed in metric tons when handling non-containerized cargoes, and in boxes when containerized cargoes. Productivity rates on non-containerized cargoes vary according to type of commodities handled and type of vessels serviced, while on containerized cargoes the rate is based primarily on the quay crane performance.
Productivity rate is computed at net gang hours, that is any standby hours caused by rain, vessel mechanical trouble, and other factors not attributable to the cargo handler, would be deducted from gross operating gang hours. For purposes of determining the productivity rate on a per day bases, OPASCOR assumes a "maximum 20 operating hours" per day per gang, exclusive of any standby hours.
