How Does it Work?
An IWOCS is a temporary control system used to commission, workover, troubleshoot, or decommission subsea wells. Specialized equipment such as umbilical reels, hydraulic power units (HPUs), and winches are used to enable hydraulic and electrical control of subsea trees and related hardware.
Reliable and Cost-Effective Operations
Our systems can be used to control all subsea trees and/or landing strings, regardless of equipment manufacturer, configuration, or work scope. Adaptable equipment and experienced personnel significantly reduce your interface risk. Our IWOCS fleet can be mobilized and operated from a wide range of vessels and rigs.
