Well Controlled Solutions
eP's Well Controlled Solutions are based on decades of experience in this industry and are comprised of Wellhead Control Systems, Subsea Systems, and Control Services. Our control systems include wellhead, process, pipeline, and ESD control, as well as self-contained hydraulic power units (HPUs) and injection systems. The subsea solutions provided by eP are made up of our Electro-hydraulic Multiplex Subsea Control System, which is a modular design concept incorporating well proven technology and qualified components to minimize both CAPEX and OPEX costs.
Included among the solutions offered by eP are:
· Installation Workover and Control Systems (IWOCS)
· Subsea Control Module (SCM)
· ROV Installable Subsea Control Module (SCM)
· Control Systems
Wellhead Control Systems
eP's control systems are based on 30 years of hydraulic and pneumatic control systems experience throughout the world. These systems include wellhead, process, pipeline, and ESD control, as well as self-contained hydraulic power units (HPUs) and injection systems.eP can provide the complete solution for wellhead control and automation. A wellhead control panel supplies the necessary hydraulic pressure to operate the SSSV (sub surface safety valve), the SSV (surface safety valve) and the WV (wing valve). Data from the well site can be transmitted via an eP RTU situated in the wellhead control panel, to a host SCADA system. Remote operation of the valves is also possible via the host system.
Power for the complete package can be from a local electricity supply, air supply, solar panels or the flowline gas.
Subsea Control Systems & CALM Buoy
eP's CAC Electro-hydraulic Multiplex Subsea Control System is a modular design concept incorporating well proven technology and qualified components to minimize both CAPEX and OPEX costs.
The integrated system provides the requisite monitoring, control and shutdown functions by means of multiplexed electro-hydraulic control, utilizing communications on power between a surface Master Control Station and Subsea Control Module, via a composite services umbilical and appropriate subsea distribution units.
The system can be used as a tie back to an existing platform to economically produce hydrocarbons from a marginal field, or from an FPSO (Floating Production Storage and Offloading Vessel) for full field production.
The system is designed for deployment and Intervention by means of ROV, guideline running tool and guidelineless running tool with ROV assistance in very deep water, featuring a simple sliding plate design locking down mechanism, however a similar module is used for diver installation.
The Subsea Electronics Module is surface removable and replaceable without the need to disturb the module hydraulics chamber.
Electrical and Hydraulic connections are made using Low force connectors mounted on the base of the unit, which automatically connect when the unit is locked into place.
Communications between topside and subsea modules is by means of a 'Lonworks' Power Line Carrier, tested with a step out-of 30Km. Communications can be adapted to suit comms on power, twisted pair or fibre optic, dependent on field configuration.
When offloading is required a CALM buoy can be used. Remote operation of valves is required complete with data acquisition from the buoy, which can be rate of approach, hawser loading, etc. eP can offer this package which includes a hydraulic power unit, buoy situated RTU, communications, solar power and navigation aids, therefore providing the complete solution from the subsea wellhead to the tanker.
