The Coast Guard is NCAs most important resource and collaborator from the Armed Forces. The Coast Guard Act regulates this co-operation. In addition to that, a separate agreement has been entered into between NCA and the Coast Guard, as a supplement to the overall co-operation agreement between the Armed Forces and NCA, and the Coast Guard Act. In this agreement, there is a separate section on adapting the Coast Guard's vessel for oil spill preparedness.
In practice, this means that in the case of newbuildings, conversions or the acquisition of vessels for the Coast Guard, these oil spill response tasks are adapted to the extent possible without this being at the expense of the primary tasks. In addition, the agreement regulates the permanent placement of oil spill response equipment on the vessels. As a result of this point in the agreement, all "new" vessels in the Coast Guard are designed for and equipped with oil spill response capabilities (a total of 12 vessels). New Jan Mayen-class coastguard vessels, which will replace the North Cape class, will all be equipped with oil spill response capabilities in contrast to the current North Cape class. This collaboration involves faster response and mobilization of oil spill response equipment than if the oil spill response equipment had been stored on land. The Coast Guard and NCA share the use of two surveillance aircrafts, together with the Norwegian Oil Spill Prevention Association for operating companies.
In 2020, the Coast Guard and the NCA entered into an agreement on the operational execution of state towing preparedness. As a result of this agreement / collaboration, the Coast Guard added two new tugs, which are a full-fledged part of the Coast Guard. This co-operation strengthens the Coast Guard's ability to carry out its primary tasks, at the same time as the Coast Guard's accessibility for other state actors is increased.
