Original warning text
M/V Alvenus; Calcasieu River bar channel, 11 miles SE of Cameron, Louisiana. Calcasieu River bar channel, 11 miles SE of Cameron, Louisiana. 1. On July 30, 1984 at 1236 the U.K. Tank Vessel Alvenus grounded in the Calcasieu River Bar Channel 11 miles southeast of Cameron, Louisiana. The vessel suffered a structural failure which ruptured the hull near the No. 2 tanks. The resulting spill of approximately 65,500 barrels of Venezuelan Merey and Pilon crude oil was carried in a westerly direction by wind and currents. Offshore recovery was hampered by rough weather and the magnitude of the spill. The water temperature was 80?F and winds were from the east and northeast 15-20 knots. The spill moved slowly westward, coming ashore near High Island, along the Bolivar Peninsula, and into Galveston Bay, Texas between Aug. 2-5. Oil impacts were severe at Rollover Inlet and Crystal Beach, and on Aug. 4 more oil was pushed ashore further south along the Galveston Island coast. The spill affected 90% of Galveston's West Beach, including 80% [...] 2. COMMODITY: VENEZUELAN MEREY, PILON CRUDE. MAXIMUM POTENTIAL RELEASE: 2750000 GALLONS. 3. POSITION 29.583N 093.250W.
