When the DYNACHEM attempted to anchor and hook up to the #2 mooring, a hydraulic winch failed and caused the ship to abort the attempt and weigh anchor. The #3 mooring pipeline was severed when it was snagged by the starboard anchor. The ship was not damaged nor at risk and moved off and anchored at a safe distance. At the time of the accident there was a maximum potential of 7,320 barrels of gas-oil in the pipeline (a combination of the 26-inch cargo transfer line and a 12-inch line in a looped configuration). The gas-oil, a non-marketable diesel-like product, is used to push remaining product out of the 26-inch line after tankers have finished transferring their cargo.
