Subsea Control Module

Weatherford’s integrated system provides the required monitoring, control and shutdown functions by means of multiplexed electro-hydraulic control. Communications are provided using communications-on-power modems between a surface master control station (MCS) and subsea control module (SCM) via a composite services umbilical and appropriate subsea distribution unit(s). In addition to the control module, a data module may be used to bring open communications to a field to integrate Weatherford and third party communication devices, for example flow metering or downhole sensing.

The data or control module system is designed for deployment and intervention by means of a remotely operated vehicle (ROV) or diver intervention using a similar module. Assisted guideline and non-guideline running tools or funnels are available with ROV assistance in very deep water. These feature a simple sliding plate design locking down mechanism.

Electric and hydraulic connections to the ROV SCM are made using low-force connectors, mounted on the base of the unit, which connect when the unit is locked into place and via a stab-plate arrangement for diver installed systems.

The MCS provides the subsea power and communications interface between the installed subsea control module(s), the platform/vessel control system and any other third party systems, via serial or Ethernet based network connections. The modular MCS provides a compact and flexible solution for ease of integration into new or existing equipment rooms. Optionally equipment may be supplied for hazardous area installation.
