The Coast Guard said it responded to a fire aboard an APL container ship at the Port of Seattle over the weekend.
The Washington Department of Ecology, APL, the Seattle Fire Department and Customs and Border Protection worked through the weekend to monitor conditions aboard the 873-foot APL Peru.
The vessel's crew reported smoke and heated bulkheads in and around the ship's number five cargo hold Oct. 5 while transiting from Hong Kong.
There were no reports of injuries.
The Coast Guard said the smoldering fire was persisting in the number five cargo hold. Coast Guard and fire department officials aboard the ship determined the smoldering is contained and there is little risk of the fire growing.
Seattle firefighters removed four smoldering containers from the ship Saturday. Holes were cut into the containers and water was pumped in to smother the contents. It is believed the containers held clothes, shoes and appliances. The cause of the heat and smoke is under investigation.
Crews worked to pump additional carbon dioxide into the hold in order to smother what remains of the fire.
