AN ANALYSIS OF EXPECTED OIL OUTFLOW FROM TANKERS IN COLLISION AND GROUNDING USING A SIMPLIFIED METHOD

As part of the IMO's "Comparative Study on Oil Tanker Design", Lloyd's Register (LR) analysed the expected oil outflow from eighteen double hull and mid-deck designs in collisions and groundings using a simplified probabilistic methodology. This methodology incorporates distributions of damage location and damage penetration as derived from LR's statistical analysis of Classification Society technical records, in conjunction with the results of extensive model tests conducted in Japan and the USA. Expected oil outflow calculations were undertaken for a series of collision and grounding scenarios, which included a sensitivity analysis of both initial oil loss following impact, and retention in the double hull space. From the analysis it was found that, in general, the mid-deck tanker designs have a lower oil outflow rate with respect to corresponding double hull designs. It was also concluded that the subdivision of the cargo tank section has a significant influence on the calculated expected oil outflows.
