Half-way into this decade and the downward trend in oil spills from tankers is sustained. For the last two and a half decades the average number of incidents involving oil spills from tankers has progressively halved, with the current figures showing the lowest yet, at less than 2 per year.
At a time when focus on protecting the marine environment is high, this trend should provide encouragement to tanker owners. It is also a testament to the ongoing work by industry and governments to maintain high standards of operations in sea-borne transportation.
During the year, ITOPF recorded 1 large spill of bitumen (~3,000 MT) from a tanker in the South China Sea, and 4 medium spills of various oil types, totalling 5 spills of 7 tonnes and over. Interestingly, a number of tanker incidents reported in the media in 2014 involved fire and explosion, where potentially significant quantities of cargoes and bunker fuel burned. The cargoes involved included condensate, diesels and fuel oils.
Major Oil Spills
A brief summary of the top 20 major oil spills that have occurred since the TORREY CANYON in 1967 are shown below; it is of note that 19 of the largest spills recorded occurred before the year 2000.
A number of these incidents, despite their large size, caused little or no environmental damage as the oil was spilt some distance offshore and did not impact coastlines. It is for this reason that some of the names listed may be unfamiliar. EXXON VALDEZ and HEBEI SPIRIT are included for comparison although these incidents fall some way outside the group in terms of volume spilt.
