In addition, the workers stopping during breaks and changing the work teams%u201f shifts.D - lack of rehabilitation and training centers and sufficiency of what labor force gains from experience and skill through actual practice only, which quickly decreases by changing workers with experience and practical training to not officially employ them and employ others according to the course for each group.4 -Average possible productivity of berth / day= Average potential productivity of the berth / hour x number of hours of daily operation =110.7x 16 = 1771.2 tons/day5 -Average possible productivity of berth / annually =Average possible productivity of berth / day x (number of days in a year - number of non-working days) x appropriate rate of berth occupancy = 1771.2x (365 - 45) x 80% = 453427.2 tons/yearAssuming that the number of multi-purpose berths in the port of Hodeida is 4 berths... average possible productivity of total berths / year = 453427.2 x 4 = 1813708.8 tons / year. %u2022For the bulk wheat unloading berth The mechanically imported bulk wheat is unloaded from vessels to grain silos and mills by means of Air suction and conveyor belt, in addition to a movable project consisting of mobile containers equipped with modern machines for packing loose wheat in case grain silos are full. The possible productivity of bulk wheat unloading berth equipment can be calculated taking into account some factors, including:a- The maximum achievable capacity does not exceed 90% of theoretical capacity under which wheat vacuum suction equipment is designed.B- unloading efficiency decreases as grain level decreases inside storage sheds of ship, and moving the ends of the conveyors straws and picking up grains from sides of holds. Therefore, unloading efficiency is 100% when discharging or unloading 85% of the ship%u201fs cargo volume, while it decreases to 25% for unloading the rest of cargo. It is 15%, so
