BATH, Maine — Bath Iron Works President Dugan Shipway is retiring this spring after leading the Navy shipbuilder for six years.

Shipyard spokesman Jim DeMartini says senior staff received word Wednesday night, and an internal communication has gone out to shipyard employees.

He says Shipway’s retirement will be effective April 1. He’ll be replaced by Jeff Geiger, senior vice president of operations.

There’s no immediate word on what Shipway’s future plans involve. DeMartini says Shipway and his wife plan to stay in Maine. Shipway is a retired Navy rear admiral. His main push since arriving at the shipyard in 2003 was to improve efficiency.
