The SS Puerto Rican, was an American-flagged tanker disabled by an explosion on October 31, 1984. The 20,295 GRT, 632 ft (192.6 m), tanker was owned by Bankers Trust Company and operated by Keystone Shipping Co. of Philadelphia which burned in an explosion with the stern section sinking just hours after leaving San Francisco bound for New Orleans with a cargo of 91,984 barrels of lubricating oil and additives. In addition to the cargo the ship was fueled with 8,500 barrels of Heavy Fuel Oil (Bunker C) before departure.

Puerto Rican Tanker Disaster
The ship had departed just after midnight and was in the process of disembarking the pilot at 3:24 a.m. when an explosion occurred near the No. 6 center-independent tank blowing the pilot Captain James S. Nolan and two crew members into the water. The pilot boat San Francisco rescued the pilot and one of the two crew members.

The ship was eight miles off the Golden Gate on October 31, 1984, at 3:24 a.m., when she was torn by a very large double explosion just forward of her deck house. A 100-foot section of deck, the whole width of the vessel, was thrown up and then back down forward on the deck in front of it, as flames shot hundreds of feet in the air.

A bar pilot, the third mate, and a crew member were thrown into the sea. The pilot boat San Francisco rescued the badly injured pilot and mate, but the crewman was lost. As fire raged onboard, the Coast Guard towed the crippled ship further out to sea, to keep her from breaking up and dumping her cargo near San Francisco Bay. On November 1, a storm passed through the area, battering the Puerto Rican with 35-mile-per-hour winds and 16-foot-high seas. That evening, after 32 hours of effort, navy fireboats finally extinguished the fire. On November 3, 30 miles southwest of the Golden Gate, she broke up, her stern section sinking to a depth of 1500 feet within the boundaries of the Gulf of the Farallons National Marine Sanctuary. Over a million and a quarter gallons of refined petroleum products, about one-third of Puerto Rican's cargo, went into the water. More details
