In global terms, safety of ship to ship operation should be recognized that operational efficiencies delivered by a large number of ship operators would make an invaluable contribution to reducing oil pollution. Spillages and leakages during bunkering operations are a primary source of oil pollution from ships. Risk of oil pollution during STS transfer operations need not be greater than during in-port cargo transfers. However, as a transfer area may be out of range of port services a contingency plan within the SOPEP (Shipboard Oil Pollution Emergency Plan) or VRP (Vessel response plan) to cover such risk should be available and should be activated in the case of an oil spill.Existence of portable tools box of SOPEP plays a major role in emergency preparedness. The purpose of a portable tools box of SOPEP is to establish a mechanism for a ship to improve the energy efficiency of a ship's operation and emergency .This paper shows the effect of existence of portable tools box of SOPEP near the manifold and how it can be useful
