In response to an earlier article by L. J. Carter, T. S. Wyman (Chevron Shipp. Co.) indicated that proper operation of the segregated ballast tank (SBT) system would require heavy reliance on vessel personnel to prevent pollution. Routine washing of cargo tanks on ballast voyages after cargo has been discharged and periodic ballasting of cargo tanks especially during heavy weather would create a potential for marine pollution with SBT's. On the other hand, crude oil washing conducted in port under close supervision avoids this possibility of marine pollution. However, according to A. McKenzie (Tanker Advisory Cent. Inc.), the U.S. tanker industry requires firm government action to establish standards for tanker construction and operation that are considerably more effective than those presently in force. The U.S. should unilaterally pass legislation to, e.g., stop using water in the cargo tanks of tankers for washing and ballasting, retrofit existing tankers with SBT's and require new tankers to have double-hull segregated ballast systems. Other maritime nations will quickly adopt these actions.
