Bath Iron Works announced Friday it will lay off 30 workers and eliminate a total of 160 positions in its engineering and support organizations “as part of ongoing efforts to be more affordable,” according to a statement Friday.

In addition to the 30 layoffs, the remaining reductions will come through retirements, transfers, resignations and canceled job postings.

“We regret the impact this will have on employees and their families,” the company said in the statement.

Spokesman Matt Wickenheiser said the cuts are not related to the recent loss of an estimated $10.5 billion contract to build new cutters for the Coast Guard, which was decided just last week.

With more than 5,500 workers, BIW is one of Maine’s largest private employers.

“These reductions are a result of our ongoing efforts to reduce costs companywide,” Wickenheiser said.
