Bath Iron Works is laying off 30 workers as part of a larger elimination of 160 positions at the company.

BIW on Friday announced that 30 workers would be layed off and another 130 positions would be cut through retirements, transfers, resignations and canceled job postings, mostly in engineering and support areas such as human resources and finance.

The layoffs are “part of ongoing efforts to be more affordable” and not due to last week's announcement that BIW was unsuccessful in its bid to build a new class of offshore patrol cutters for the U.S. Coast Guard, the company said in a statement released on Friday.

“We regret the impact this will have on employees and their families.”

BIW's more than 5,500 workers makes it one of the largest private employers in Maine.
