C-Innovation Plays a Key Role in First Oil at Salamanca for LLOG Exploration
C-Innovation (C-I), an affiliate of Edison Chouest Offshore (ECO) and its family of companies, has successfully completed a series of light construction campaigns on the Salamanca field in the Gulf of America in partnership with LLOG Exploration and Pinnacle Engineering.
The completion of major subsea installation operations utilized the company’s specialized marine assets and technical expertise to deliver comprehensive offshore services. -I deployed the MPSV Dove equipped with a 150-ton crane and C-Leader offshore supply vessels (OSVs) to support critical subsea infrastructure installations over a 100-day operational period. The project scope encompassed multiple complex subsea installations, demonstrating C-I’s capabilities in handling large-scale offshore operations. The total weight of the most complex lift was a jumper weighing 143,245 lbs, including spreader bar, rigging, and jumper components. Hub-to-hub length was 96 ft 3-5/8 in. in a Z-shape configuration. Nathan Wolford, project manager, C-I, said, “This project demonstrates C-I’s ability to execute complex subsea installations with precision, utilizing the Dove vessel’s 150-ton crane to successfully install a substantial 16 in. oil export jumper.
The demanding Z-shaped configuration and significant weight requirements showcased not only advanced engineering execution but also the specialized marine handling expertise of our team.” Completed installations included:
1 x 16 in. gas export jumper installation
1 x 10 in. gas export jumper installation
1 x 16 in. oil export jumper installation featuring Z-shaped configuration
2 x Leon flowline jumpers
2 x Leon well jumpers
1 x Castile well jumper
Additional operations included comprehensive support for pigging and dewatering operations, precision metrology services, and hull inspection services. This series of installations contributes to a major milestone in the Gulf of America Leon-Castile field development, with first oil now flowing to the Salamanca hub.
