C-Innovation, an affiliate of Edison Chouest Offshore (ECO), has signed a two-year contractfor continued riserless light well intervention (RLWI) services on board offshore construction vessel Island Venture
This new contract follows a previous agreement in whichIsland Ventureperformed interventions on multiple deepwater wells in the Gulf of Mexico.
The highly capable 159-m, Vanuatu-flag offshore construction vessel was built in 2017 by Ulstein Verft. It can support installation, maintenance and repair, ROV services, well intervention and drilling. An SX165 design, Island Venture has a maximum operational crane depth of 4,000 m, main moonpool opening of 11 m x 12 m and two work-class ROV moon pools.
C-Innovation (C-I) vice president David Sheetz said, “This new award is a continuation of nearly three years of setting new standards in the RLWI space. We look forward to the next few years on this project, and we are already making plans to expand the offering, including numerous dock upgrades to facilitate even more efficient fluid handling and waste removals to minimise required between-wells maintenance time.”
With no safe vertical access to several subsea wells under a platform, the C-I Subsea Projects Group will use a well service jumper to perform well interventions. This collaborative effort between C-I and the operator was a first for the industry and allowed C-I to perform the intervention without disrupting the platform’s operations.
C-I RLWI project manager George Wilson said, “C-I is committed to ensuring the continual improvement of the quality, health, safety and environmental aspects of its operations and services. The two-year RLWI work is no exception: with over 1M man-hours, C-I had zero recordable incidents. So far this year, C-I has clocked over 135,000 hours with no recordables.”
Mr Sheetz added, “Our team continues to provide creative solutions and methodologies to perform interventions that have not been achievable from a conventional RLWI approach. The collaboration of various subsea disciplines within our group has contributed to the successes, and our offshore teams continue to deliver on every execution that comes their way. C-I’s subcontractors, Halliburton, Baker Hughes and Caltex Oil Tools, were also key to the new award.”
