The move comes after a group of creditors filed an involuntary petition to force the Mobile River shipyard into bankruptcy, saying Bender was failing to pay its debts. Bender had fought that move, but said in court filings that other customers began to balk at doing business with the firm. Monday, U.S. Bankruptcy Judge Margaret Mahoney ruled that Seacor Marine LLC of Houma, La., was due to collect a $5 million guarantee from Bender that was secured by Regions Bank, because Bender had been facing the prospect of involuntary bankruptcy for more than 10 days.
