Last weekend the HMCS Calgary spilled 30,000 litres of fuel in the Strait of Georgia between Nanaimo and Parksville. The spill happened while crews aboard the vessel were transferring F-76 fuel internally. F-76 is a naval fuel used in compression ignition engines, naval gas turbines and ships' boilers for steam raising and is similar to kerosene, lighter than water and quickly evaporates. Canadian Coast Guard has conducted air, sea and land-based searches and have found no evidence of the fuel on the shorelines. The spill was likely caused by human error, but a full investigation is underway.
