Valve solution pressure surges pipelines

Upgrade valve solution protects against temporary pressure surges in pipelines

Customer stories – Reference sheet

Equinor Mongstad – Johan Sverdrup

Location: Mongstad
Period: 2017 – 2018

Client: Aker Solutions, Bergen
Field of application: Pressure surge protection – loading area

BHGE Flexflo anti surge valves has been installed at Mongstad and has protected instruments and pipelines from potentially harmful pressure surges for approx 30 years. When the Johan Sverdrup field started in 2019 the volume and the viscosity of arriving oil will increased. The anti surge valves also had to increase their capacity to accommodate the new situation.

Instead of installing extra surge relief valves we suggested adding capacity-boosting instrument panels for 11 existing valves. With this solution, each valve will gain a higher capacity and the number of total required relief valves will actually decrease. Fever anti surge relievers will also ensure lower maintenance costs in the future.

As a part of the upgrade, some of the internal parts of the existing surge relievers were replaced.
