THE BUREAU VERITAS COMPUTER PROGRAM FOR CHECKING THE CRUDE OIL WASHING EFFICIENCY IN TANKERS

The 1978 Protocol to the MARPOL 1973 Convention for tanker safety and marine pollution prevention authorised the cleaning of tanks by crude oil washing provided certain standards of efficiency were attained. If the cleaning guns be looked upon as light sources, a tank can be considered efficiently cleaned if the ratio of shadow surfaces to vertical surfaces is less than 15% and that of the shadows to the horizontal surfaces less than 10%. The Bureau Veritas computer program COW <Crude Oil Washing> satisfies all the conditions of the 1978 Protocol, but the checking of shadow areas is only part of these conditions. In this paper, the Authors describe an additional program designated SHACOW <Shadows in Crude Oil Washing> which is designed to check the accuracy of the drawings of shadow areas sent to Bureau Veritas by shipyards for approval.
