PROJECT EXPERIENCE
Mandy Development & Matterhorn TLP
Mandy Development & Matterhorn TLP
Client:
LLOG Exploration & W&T Offshore
Location:
Gulf of Mexico, MC-199 and MC-243
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.
