OneSubsea offers an electric subsea production system, a first-of-its-kind, truly comprehensive production system that comprises electric valves, trees, chokes, and manifolds. Each component of this system uses electrically driven actuators. Industry-standard electrohydraulic actuation can be heavy, logistically complex, environmentally risky, and costly. Our all-electric technologies enable flexible, cost-efficient, and reliable subsea production with reduced intervention requirements—especially useful in challenging environments such as ultradeep water and long step-outs. An optimized portfolio of actuators addresses a wide range of applications, greatly reducing your inventory and costs.
Our electric subsea actuators are a low-weight solution for operation of heavy valves with electric motors. They use standard electric power systems and require no hydraulics in the supply or actuation system, eliminating heavy topside equipment (e.g., hydraulic power unit). They provide greater control and precision while reducing size and weight of actuation systems, subsea infrastructure, testing time and cost, logistics and installation cost, HSE risks, and water contamination.
Compared with conventional electrohydraulic systems, our all-electric subsea systems can reduce costs by up to 20%.
Using high-voltage DC for long-distance power transmission is significantly more efficient compared with either AC power or hydraulic pressure.
Our electric umbilicals have a smaller cross section, enabling the manufacturing and spooling of longer continuous lengths and facilitating the use of a smaller installation vessel. And on long step-outs, splices in the umbilical can be reduced or even eliminated. Overall equipment weight is also reduced, and small-bore welding is reduced by up to 60%.
Because hydraulic fluid is not required for actuation, the risk of discharging hydraulic fluid into the environment and hydraulic pressure safety issues are completely eliminated.
Electric actuators can also be used to electrify existing subsea equipment in brownfields and introduce new functionality, such as remote valve control.
This field-proven lightweight actuator can generate up to 270 N.m of torque. Suitable for operating small-bore valves, electric chokes, and electric manifold valves, it supports a range of industry-standard subsea communication interfaces.
This electric actuator is able to provide up to 2,700 N.m of torque. A range of gearbox configurations is available, making the actuator suitable for multiple applications and valve types. It can be used on electric chokes, electric manifolds, electric boosting stations, pipeline end terminations, and more. It complies with several industry standards for communication and power interfaces.
