From NY TIMES Coast Guard Opens Inquiry Into Staten Island Explosion The Coast Guard began hearing public testimony yesterday in its formal investigation into the huge barge explosion at a Staten Island fuel depot on Feb. 21 that killed two crew members and severely injured a worker. Investigators have been focusing on a pump that may have malfunctioned, though an employee testified yesterday that the pump had been tested before the blast. The investigation, led by Cmdr. Patrick E. Little of the Coast Guard's marine safety office in Providence, R.I., is intended to determine the cause of the explosion as well as to gather information to help prevent or better respond to similar problems in the future, he said in his opening statement. Officials plan to question 17 witnesses by day's end tomorrow, and to reconvene a little later with a second group of witnesses. Lt. Comdr. Joseph Fischetti, a Coast Guard spokesman, said that Commander Little would probably not submit his final report for about six months. Although the investigation is being coordinated by the Coast Guard, which is responsible for licensing ships and crews, the National Transportation Safety Board is also participating because it is responsible for determining the cause of major accidents, Commander Little said. Yesterday's session focused on establishing what was happening at the terminal just before the deadly blast at Port Mobil on Arthur Kill. The explosion occurred after the unloading of about 50,000 barrels of unleaded gasoline from a 200-foot barge, killing the vessel's captain, John Kyne, and mate, Ford Ebanks. Mr. Ebank's family has filed a $10 million lawsuit against Bouchard Transportation, a Hicksville, N.Y., company that owns the barge and employed both men. Lawyers for both families were at the hearing, along with representatives of Bouchard; ExxonMobil, which uses the depot to store motor fuels and heating oil from vessels and from a pipeline running northeast from oil refineries in the Gulf Coast; and SeaRiver Maritime Inc., an ExxonMobil marine transportation affiliate. Theofanis Tskas, a Bouchard employee who had serviced the suspect pump hours before the blast, said that it had tested successfully, Lieutenant Commander Fischetti said, emphasizing that the pump was only one system under investigation.
