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 and Brent Delta.

For ConocoPhillips, we undertook environmental studies for decommissioning the Ekofisk tank. We also evaluated the mitigation alternatives and assisted in the design of a leave-in commissioning solution in which all topside structures were removed.
