NoCGV Harstad is a purpose-built offshore patrol vessel for the Norwegian Coast Guard. She is named after the city Harstad in Northern Norway. Harstad was built as a multipurpose vessel, but optimised for emergency towing of large oil tankers (up to ), oil spill clean-up and fire fighting. The most common duty will be fishery inspection and search and rescue in Norway's large exclusive economic zone. The steadily increasing traffic of large oil tankers along the Norwegian coast explains the need for this type of vessel.
