The U.S. Coast Guard Marine Safety Detachment in Kenai is investigating a minor crude oil spill that occurred this morning on the Dillon oil and gas production platform located in Cook Inlet. The source of the spill on the platform was a cracked fitting on the discharge side of a high-pressure pump used to re-inject crude oil into the well. The exact size of the spill is unknown, but reports from Unocal officials indicate that the maximum size of the spill was 2,310 gallons. Most of the spilled product did not enter the waters of Cook Inlet, but was contained on the platform. It is not known how much crude oil entered the water. Unocal, in conjunction with CISPRI, conducted over flights of the area and also dispatched the spill response vessel Sea Bulk Montana to the spill location.
