C-Innovation has offered its clients a broad spectrum of integrated project services and has met the most challenging of subsea demands. Our project management and engineering teams join forces on every project onshore or offshore to bring a complete solution to the table for clients.

The engineering and project management and execution teams at C-Innovation offer years of experience over a multitude of project types. Our projects have included:

• Flowline and well remediations (including hydrate, asphaltenes, acid and chemical treatments, scale squeeze, etc.)
• Well tie-ins including subsea tree, jumper and flying leads installations
• IRM inspections
• Flotel operations
• Offshore platform topside scopes
• Subsea structure installations including:
  • Manifolds
  • Well and Flowline Jumpers
  • Suction Piles
  • Flying Leads (SFL & EFL)
  • Subsea skids
  • Subsea control units (SCMs, CIMV’s, chokes, etc.)

The RLWI Team was awarded a two-year contract in March 2022 for continued Riserless Light Well Intervention (RLWI) services onboard the Island Venture offshore support , a 160-meter (525′), DP-3 vessel is ideally suited to perform deep-water riserless interventions in the Gulf of Mexico.  The award also has a mechanism to pull in other vessels which the client has optioned to pull in the Island Intervention for a year of well intervention work. The contract follows a previous 3 year agreement which began in 2019.  The Island Venture and Island Performer have executed over 25 well interventions on multiple Deepwater wells in the Gulf of Mexico since 2019.

The RLWI team continue to improve performance and efficiencies through the knowledge we have gained over the past five years, executing over 40 Well Interventions since 2017.  The Interventions performed have been both mechanical e-Line and slick Line type interventions as well as straight hydraulic stimulations.  Additionally C-Innovation’s RLWI Team have developed methodologies to perform interventions that have not been achievable from a conventional RLWI approach, such as; Riserless Interventions of sub ambient wells and interventions that have no vertical well access. C-Innovation collaborative approach of our various subsea disciplines the operators and our subcontractors have contributed to our success.

With our highly reputable project management and consultancy expertise, we offer a competitive advantage to our global customer base without having to venture outside the diverse and large family of Chouest companies worldwide.

For our U.S.-based clients, as well as for clients in Brazil, Guyana and beyond, the C-Innovation team undergoes the adequate training on the use of local content to sufficiently provide our offshore project execution services.

CASE STUDIES

• Shell Europa (2019)
  C-Innovation vessels Island Venture, Island Performer, Carol and Fast Hauler were brought to the Europa Pipeline where a Phase 2 completion took place. Pipeline communication was achieved to the Mars platform following four tractor runs: Run #1 – 14,500’ Run #2 – 26,980’ (world tractor distance!) Run #3 – 22,000’ Run #4 – 26,038’ The… Read More
• Perdido 4-Well Campaign
  A total of five well stimulations were completed for this campaign, most notably Coulomb C4 and Perdido 4-Well.
• Perdido 4-Well
  This was first executed by the C-I team for Shell, as a multi-well intervention and infield fluids supply project. Our team pumped four scale inhibitor squeezes by accessing one well (GA12), and continuing work within 150 feet of spar.
• FS2 Fluid Loss Isolation Barrier Valve
  Project Details Client: ExxonMobil Location: Julia Field   Overview Open an FS2 valve using UHD ROV power only.   Challenges Create a viable and economical procedure using an UHD ROV and related equipment that is compact and powerful enough to actuate the FS2 valve through existing tree communication ports.   Client Solution We designed, built… Read More
• Pipeline Remediation
  Project Details Client: Major O&G Operator Project: Europa 136 W Flowline Remediation Location: GOM – 3500’   Overview The primary objective of this project was to clear the flowline of an extensive asphaltene blockage to satisfy government decommissioning requirements.   Challenges Accessibility to the flowline Blockage was closer to the upstream/PLET end of the flowline… Read More
