Decrease your opex, capex, and environmental footprint

The all-electric actuator lowers your opex by up to 30% via reliable, long-term remote control of surface valves as well as condition-based monitoring and money-saving predictive maintenance. By eliminating unnecessary site visits and personnel on location, these actuators enable you to rethink platform design, potentially removing costly structures such as helidecks, living quarters, and control rooms. Reducing maintenance visits also decreases CO2 emissions. Asset field crews can run leaner because technicians are better informed about the maintenance required.

Hydraulic actuators require periodic control fluid replacement and disposal and are sensitive to control fluid contamination. They must be monitored for leaking control lines, consume more energy, and require bulky generators and pump motors, which occupy additional space and create higher CO2 emissions. The all-electric actuator can use alternative energy sources (including solar or wind) or electric umbilical or battery power.


All-Electric Surface Actuator

Automated operation

Integrated sensors track actuator position and current in real time, and smart actuator controls enable dynamic monitoring and control of parameters such as the drive motor condition, winding temperature, housing fluid pressure, motor torque, stem leakage, and other associated alarm and health conditions.

Actuator designs are fail-close, using a clutch to disengage the valve from the electrical system and enable a mechanical spring to rapidly close the valve.

The smart control system features interfaces with your SCADA systems or distributed control systems (DCS) using industry-standard communication protocols. It also has a wireless human machine interface (HMI) for local operation and monitoring during intervention.

† Emissions reductions come from two sources. Decrease in travel-related emissions is based on reducing annual maintenance visits by a 3-person crew from 26 to 2, with an average round-trip distance of 200 mi. Energy and additional emissions reductions assume eliminating operation of a 282-kW hydraulic power unit (HPU) for 26 days annually. Electric actuator emissions and energy consumption are based on 60 valves operated for a total of 6 hours annually and take into account the constant-draw energy requirements to keep the actuators in the open position. All power is assumed to come from the US electrical grid. Potential emissions avoided will change depending on the source of power.
