Original warning text
T/V R. HAL DEAN; Bayou Cassotte, Pascagoula, Mississippi. Bayou Cassotte, Pascagoula, Mississippi. 1. At 1840 on July 14, 1989, the Chevron tanker R. HAL DEAN, loaded with 395,000 barrels of Mayan crude, ran hard aground while moving into the Bayou Cassotte and Pascagoula Ship Channel near buoy #14. Although the vessel was grounded in soft sediments approximately eight nautical miles south-southeast of Pascagoula, Mississippi, and was reportedly not leaking, there was concern because she is a single-hulled vessel and was in an area studded with abandoned buoy anchors and other debris. Chevron's plans, approved by the U.S. Coast Guard Marine Safety Office (MSO), Mobile, called for lightering and then refloating the R. HAL DEAN using the vessel's engines and tug boats as needed. USCG district 8. 2. COMMODITY: MAYAN CRUDE. MAXIMUM POTENTIAL RELEASE: 16600000 GALLONS. 3. POSITION 30.340N 088.569W. NOAA INCIDENTNEWS 6708: https://incidentnews.noaa.gov/incident/6708
