Along with all the industry shifts, servicing wooden vessels remained a mainstay of Lake Union Drydock Company’s operation. Capitalizing on the opportunity to maintain wooden minesweepers, Lake Union Drydock Company assembled vessel-specific tooling and established craft training to service sophisticated componentry. In 1990, after the Invasion of Kuwait, the US Navy enlisted Lake Union Drydock Company to prepare the Seattle based Minesweeper Offshore (MSO) fleet for transit to the Persian Gulf.
