The Department of Ports and Harbors is responsible for managing, operating, and maintaining the Port of Dutch Harbor's five city-owned port facilities. The Department also conducts marine search and rescue services. The Department employs six full-time harbor officers and two office staff in addition to the director and the harbormaster.
The Port of Dutch Harbor strives to promote the growth and well-being of the Unalaska community by planning, developing, and managing marine-related municipal properties. Operating on a self-supporting basis, the Port of Dutch Harbor provides moorage and marine services that support marine-related commerce, fisheries, safety, recreation, tourism, and environmental protection of the Port of Dutch Harbor.
The city-owned and operated marine facilities in the Port of Dutch Harbor include the United States Coast Guard Dock, the Unalaska Marine Center, the Spit Dock, the Light Cargo Dock, and the Robert Storrs International Small Boat Harbor.
The Unalaska Marine Center (UMC) and the Coast Guard Dock contain about 625 meters of dock face with alongside depth of 12.2 meters. The Port of Dutch Harbor's UMC provides passenger, cargo (including containers), warehouse space, and other port services. Horizon Lines operates a crane and rail system for containerized cargoes through the UMC, and fueling facilities are operated by North Pacific Fuel.
