Project summary

Audubon provided topsides engineering support and modifications to W&T Offshore’s Matterhorn TLP production system. We also integrated the production system with LLOG Exploration’s Mandy development and topsides equipment.

Modifications to the topsides facilities were completed to receive, separate, and meter production on the Mandy prior to merging with production at Matterhorn. Our engineering, design, and installation services supported two risers that tied back to three Mandy wells and combined a four-slot subsea manifold prior to flowing to the Matterhorn TLP.
