Stril Mariner currently operates as an emergency response and rescue vessel for Ula and Tambar, undertaking both emergency response and operational tasks.

Aker BP is working to streamline the vessel logistics on the southern field and consequently wishes to remove Stril Mariner from Ula.

Compensatory measures will be taken to ensure that emergency response is maintained and that the operational tasks are covered by other solutions.


Ula is a field located in the southern part of the Norwegian sector in the North Sea. The water depth in the area is 70 metres. Ula was discovered in 1976, and the plan for development and operation (PDO) was approved in 1980. The development consists of three facilities for production, drilling and accommodation, which are connected by bridges. Production started in 1986.
