A new chapter is underway for the Mariner field
Equinor has started production from the Mariner field, our first operated development in the UK North Sea. The field is expected to produce oil for the next 30 years.
The start of production from Mariner is a significant milestone, reinforcing Equinor’s commitment to be a long-term energy partner for the UK. One of the largest industrial projects in the UK in recent years—a gross investment of more than USD 7.7 billion – Mariner supports over 500 long-term jobs and will generate significant revenue in the supply chain for decades to come.
Mariner is one of our most innovative offshore developments, and Equinor is at the forefront of applying new digital solutions and the latest technologies. We are testing new ground through our offshore digital workers, automated drilling and the use of Echo, a digital copy of the platform, to deliver safe and efficient solutions.
Mariner on stream press release August 2019 Mariner will contribute to energy supplies for 30 years
The Mariner field is located on the East Shetland Platform in UK Block 9/11a in the northern North Sea approximately 150 kilometres east of the Shetland Islands
The field development concept includes the Mariner A production, drilling and living quarters (PDQ) platform based on a steel jacket with a floating storage unit (FSU), Mariner B. Drilling will be carried out from the PDQ drilling rig together with a jack-up rig assisting during the initial phase.
Equinor acquired operatorship of Mariner in 2007 and the field is expected to contribute towards reliable energy supplies for the next 30 years.
