Complete decommissioning portfolio maximizes efficiency

Ultimately, subsea assets will require production isolation and hardware removal. Leveraging the significant track record of both Helix vessels and Schlumberger services for well decommissioning activities, the Subsea Services Alliance provides capabilities with the appropriate interface to limit potential well re-entry issues. This approach has proven to maximize efficiency when it is time to decommission aging assets.

The Alliance is also capable of conducting pipeline decommissioning and hardware retrieval using its vessels equipped with deepwater lift technology for field remediation and removal activities.
