Largest offshore oil containment boom

Ro-Clean Desmi developed an offshore oil containment boom in 2000 called the Ro-Boom 3500 which has an overall deflated width of 3.5 m (11 ft 6 in).    The deflated width of containment booms normally ranges between 0.5 m -   2 m (1.6 ft - 6.6 ft).  The importance of this device is heightened by the fact that every year 100 million US gallons of oil spill.  This amount is equal to 100 standard school gymnasiums. An oil containment boom is a device used to contain oil which has been spilled from pipelines, oil wells, tankers and other vessels.  They are usually made of rubber and can inflate quickly so that they float on the surface of the water and prevent an oil slick from spreading.  The key measurement when checking the size of a boom is its width when it is deflated.  In tests 95 m³  (3,355 ft³) of oil was released in the North Sea which had a thickness of 14 cm (5.5 in).  The Ro-Boom 3500 contained 95% of this slick and in sweeping tests it managed to contain oil at speeds of up to 1.3 knots (2.4km/hour, 1.5 miles/hour).  The Ro-Boom 3500 can also contain and tow oil for long periods of time.  It survived being towed for two weeks in the middle of winter and even contained oil in waves 7m (23ft) high!
