A ferry that serves Coupeville and Port Townsend will be at the center of training exercises Saturday.

Training exercises will consist of three separate scenarios, all held on the state ferry MV Kennewick, which will be docked in Port Townsend.

“This will give us an opportunity to conduct interagency training that will help us prepare for a real disaster,” said Bill Beezley, East Jefferson Fire-Rescue spokesman, who is one of the event organizers.

Helicopters from the Coast Guard and Northwest Regional Aviation will interact with responders on the ferry and land at Memorial Field in Port Townsend between 8:30 a.m. and 2:30 p.m. as part of the exercise.

Participants will include Central Whidbey Island Fire and Rescue, Oak Harbor Police Department, the Coast Guard, Navy Region Northwest Fire and Emergency Services, Seattle Fire Department, Jefferson County Department of Emergency Management and Jefferson Healthcare, and Airlift Northwest.

Beezley said there will be some noise and observable activity resulting from the exercises but no significant public impact.

The exercises will take advantage of a two-day hiatus in ferry service between Port Townsend and Coupeville, Beezley said.

The break is to allow repairs to the Coupeville terminal transfer span Saturday and Sunday. The terminal will be closed and all ferry service on the route cancelled for the weekend.

Crews will replace a worn-out 28,000-pound hinge and a 21-foot-long, 15-foot-wide moveable bridge used to connect docked ferries to the terminal. Service is scheduled to resume with the 6:30 a.m. sailing from Port Townsend on Monday.

The late spring Port Townsend/Coupeville sailing schedule takes effect May 10, when the route’s second ferry, the MV Salish, goes into service through October.
