Simplify well access, well intervention, and workover with industry-first closed-loop subsea controls
Talk to an expertConduct reliable, flexible, and efficient Intervention Workover Control (IWOC) services on non-producing wells in a variety of subsea field applications. The umbilical-less Subsea Controls and Intervention Light System (SCILS), along with the wireless battery-operated eSCILS, revolutionize how operators perform well interventions, workovers, and P&A operations.
SCILS provides temporary subsea tree (XT) control amid completion, intervention, slot recovery, and P&A. With the addition of a safety system for emergency shutdown (ESD), SCILS can also provide control when in production mode. SCILS relocates hydraulic controls and power from the rig deck to the seabed. Operators can easily configure SCILS to interface with any XT.
Traditional IWOCs rely on large, heavy topside equipment and an extensive umbilical. The SCILS systems requires a smaller, lighter footprint due to its modular design and umbilical-less, wireless communication capabilities. This reduces transportation and installation costs and allows operators to reuse modules across different wells and projects.
Operators can deploy a SCILS unit from almost any vessel or rig and configure it for various scenarios and XT variants, which provides unmatched flexibility. This provides the ability to respond quickly to changing conditions and re-deploy assets as required.
SCILS can interface with any subsea tree or intervention tool. Operators can now standardize equipment and procedures across their portfolio. This cuts down on training and maintenance costs and maximizes subsea intervention technology investments.
Smaller topside footprint
Less umbilical subsea cross-section
Lower OPEX
Validated operating depth
SCILS’ modular design facilitates rapid deployment and retrieval. Operators can mobilize units in hours instead of days. This streamlines offshore operations, reduces downtime, and shortens the weather window required for safe installation.
Its field-tested battery package allows the eSCILS unit to operate independently, which further saves time through IMR-vessel pre-deployment. A single offshore lift can deliver eSCILS to the rig. Operators can charge the battery package subsea with an ROV or other subsea available power sources through its wetmate connector.
SCILS is a closed-loop subsea controls unit with redundant subsea pumps, control modules, and hydraulic reservoirs for both clean supply and dirty return. Built-in redundancy and umbilical-free deployment help minimize risk to personnel, the environment, and NPT. It requires fewer personnel to operate offshore because of its smaller size and simplified design. The closed-loop design and redundancy help ensure reliable XT control.
Unlike traditional IWOCS, eSCILS redefines operational efficiency and safety in completions, XT-testing, and P&A operations through the integration of innovative wireless communication. This eliminates the reliance on umbilicals and heavy topside equipment. With its field-tested battery package, eSCILS operates independently, which offers significant time savings through IMR-vessel pre-deployment capabilities. The eSCILS modular design ensures compatibility with any XT variant, which improves rig flexibility.
The system stands out for its seamless communication, operational readiness, and reduced setup time. This makes it the optimal choice for well interventions and workovers. eSCILS maximizes offshore operation efficiency and safety.
