This report develops a probabilistic oil outflow methodology based on IMO guidelines and draft regulations. Performance is measured in terms of a non-dimensional mean oil outflow parameter. The method is then applied to calculate outflow for 25 different cargo vessels (10 tankers, 6 containerships, 5 bulkers and 4 others), typical of vessels in US and Canadian waters. The results indicate a wide variation in performance in the fleet. Tank location will respect to the shell plating is a primary factor with location along the length as a secondary contributing factor. Modifying tank size and arrangements to achieve improved outflow performance may be possible. Improved performance will come at an additional cost, since the construction cost is generally greater for the better performing bunker tank arrangements that do not have tanks against the shell plating.
