An inspection conducted on the boilers of a ship before it sank in a hurricane last fall found parts that had “deteriorated severely” or needed to be replaced, but company engineers believed it was still safe enough to set sail, testimony at a Coast Guard hearing revealed Friday.

The boiler issues on the El Faro were an indication of normal wear and tear, John Fisker-Andersen, director of ship management for Tote Services Inc., told a Coast Guard investigative board.

The 790-foot El Faro sank in Hurricane Joaquin on Oct. 1 after losing propulsion while sailing from Jacksonville to Puerto Rico. All 33 crew members aboard died, including four from Maine.

The 40-year-old vessel’s boilers were scheduled for service a month after its ill-fated voyage. Inspectors had found deterioration in parts called “burner throats,” pieces of the main propulsion steam boiler that help shape the boiler’s flame and properly mix fuel and air.

Fisker-Andersen testified that nothing in the boiler reports would normally cause a cancellation of the voyage.

“There aren’t any show stoppers in here,” he said, referring to the inspection findings. “There’s nothing in here as explained to me that’s a ‘no sail.”‘

The board, made up of Coast Guard and National Transportation Safety Board investigators, has been questioning Tote officials for four days to find answers about the ship’s sinking. Another series of hearings is scheduled later this year, after which the panel will release a report. If any criminal misconduct is unearthed, the Coast Guard can refer it to the U.S. Department of Justice.

Tote officials have said Capt. Michael Davidson, who lived in Windham, was completely responsible for his voyage planning, including whether to reroute in bad weather. Multiple officials have said the company did not monitor weather and its vessels’ locations from shore at all because that is the job of the ships’ captains.

William Bennett, an attorney representing Davidson’s widow, raised questions about whether the captain had reliable weather information about the storm before leaving Jacksonville.

According to testimony, however, Davidson knew enough about Joaquin’s track while at sea to email company officials about a change in route on his way back from Puerto Rico.
