Mitigation, remediation and leave-in successes

Ramboll has had a hand in many important decommissioning projects. We conducted remediation studies for Shell on the platforms Brent Bravo/Delta.

For ConocoPhillips, we undertook environmental studies for decommissioning the Ekofisk tank. We also evaluated the mitigation alternatives and assisted in the design of:

• Leave-in commissioning solution in which all topside structures were removed
• Tank cleaning (oil and water)
• Control measures (monitoring, modelling and engineering solutions)
