The agency found that there had been eight total leak alarms before the pipeline operators in the control room shut down and isolated the line. For 14 hours, the leak continued, and the release would have been smaller if the employees had been trained to respond appropriately, NTSB said. <\/p>\n The NTSB also found that the location of the anchorage allowed too little time for ships' crews to respond to an anchor-dragging incident before hitting the pipeline. The board recommended that the U.S. Coast Guard move the boundary of the anchorage farther away for safety.<\/p>\n
