Subsea7 has scooped a contract from LLOG Exploration to provide design, fabrication, and installation of subsea systems related to the Salamanca development project in the deepwater US Gulf of Mexico (GOM). The contractor deemed the award as sizeable, which is defined as being between $50 million and $150 million.
The contract scope includes the installation of three infield subsea pipeline systems, as well as the design and fabrication of subsea structures. Subsea development will consist of two pipeline systems for the Leon field, located in Keathley Canyon 686, and one pipeline system for the Castile field, located in Keathley Canyon 736. The infield pipelines will produce and flow from wellsite PLETs to the Salamanca FPS in water depths ranging from 1800 to 2000 m.
The scope includes the installation of oil and gas export pipelines which depart from the Salamanca FPS and tie into existing pipeline transport systems approximately 48 km away.
Project management and engineering will begin immediately at Subsea7’s office in Houston with offshore activity expected to begin in 2024.
The Salamanca FPS is being converted from the former Independence Hub (IHub) platform deployed in the US GOM from 2007 until it was decommissioned in 2019.
The refurbished facility will have a production capacity of 60,000 B/D of oil and 40 MMcf/D of natural gas. IHub was originally equipped with a two-level production deck capable of processing 5,000 B/D of condensate and 1.0 Bcf/D of natural gas.
