Intervention Workover Control System Services

IWOCS Services
Beyond traditional tree installation and intervention, FMC Technologies has extensive experience in providing open-water Tree on Wire Installation and Intervention Workover Control System (IWOCS) services, alongside Well Plug and Abandonment for shallow to deep waters.

IWOCS services are designed to control the subsea tree during rig and vessel-based Well Access Systems (WAS) operations. IWOCS provides the operator with the ability to perform secure and effective installation, completion and intervention tasks offshore. Dedicated, accountable, and trained offshore engineers and technicians enable safe and reliable operations.

This service solution benefits operators not looking to purchase equipment, while still reaping the benefits of a fully operable, comprehensive system including the equipment needed from project start to finish. FMC Technologies provides operators with the project ownership, while eliminating the hassles of managing system planning, accountability, asset management, mobilization, demobilization and maintenance. FMC Technologies possesses the tools, expertise and resources to fulfill customers’ service requirements in offshore production activities.
