Oil Spill Risks from Nontank Vessels1

Abstract

ABSTRACT An issue of increasing concern worldwide is that of oil spills from nontank vessels that carry large quantities of petroleum product as fuel or lubricants. The New Carissa incident in Oregon in 1999 is only one of several that have impacted the U.S. West Coast in the last few years. Others include the M/V Kuroshima, which grounded in Dutch Harbor, Alaska in 1997, and the M/V Kure, which spilled oil in Humbolt Bay also in 1997. The Tenyo Maru was cut in half in a collision and sank with the loss of one life and a spill of at least 100,000 gallons of heavy fuel oil and diesel in Washington State in 1991. Additional examples of both spills and threats of spills are sited, both in the United States and worldwide. This paper examines a number of actions that have been taken in response to this threat. One such model is the Canadian requirement that vessel owner/operators demonstrate a formal agreement with an approved response contractor, and list that contractor in their Shipboard Oil Pollution Emergency Plan (SOPEP). A more comprehensive approach would be to establish approved “umbrella” contingency plans for major port areas, supported by contracts with oil spill removal organizations (OSROs). This preferred model has been adopted by the U.S. West Coast states, and affords the opportunity for the contracted responders to drill with emergency response officials, thus improving the likelihood of an efficient, coordinated spill response. This paper also proposes spill prevention design elements for nontank vessels.
