On the top-side facilities of offshore oil and gas platforms, the Master Control Station (MCS) is a dedicated system that controls and retrieves data from subsea equipment on the ocean floor. The MCS is supplied by the manufacturers of the subsea control modules (SCM), an MCS is required for each vendor. This can be a challenge in some scenarios. Positioned between the distributed control system (DCS) on the platform and the subsea equipment, the MCS is critical to maintaining safe operating conditions, optimizing production across a field and effectively managing reserves.〔(Dolphin Master Control Station, Control Dynamics International )〕〔(Subsea Control Systems, GE Power )〕 The complex automation systems enabling offshore production of oil & gas, particularly in deep water, have strong parallels to their on-shore, process plant applications. 〔(Production Control Systems - An Introduction, Touch Oil & Gas )〕 These systems, subsystems and instruments must interoperate in a seamless manner.〔OPC, Foundation Fieldbus, ODVA, HART, and others.〕 In 2008, Control Dynamics International of Houston, now a subsidiary of (ENGlobal ), was commissioned to develop an MCS that could communicate with and control subsea equipment from multiple vendors; dubbed the Universal Master Control Station (UMCS). ==Design Considerations & Objectives== The primary focus of the UMCS development program was to create a new standardised solution that used commercially available, off-the-shelf components. The graphics, control routines, and logic/communication functionality would be designed and implemented to provide operations a common-look control system interface. A standard interface (communication protocol) would establish a common communication link for the UMCS enabling concurrent data exchange to multiple subsea vendors. Additional scope of this initiative included: * Communication and control up to 100 Subsea Control Modules (SCM) * Expandable in the field * Based on commercially available, off-the-shelf hardware lowering the OPEX of the implementation * Components replaceable without well shut-in * Dual redundancy to alleviate a shut-in due to multiple points of failure * Communications with subsea equipment based on a widely accepted standards * Open architecture for integration with third-party subsystems Standard OPC databases serve as the communication link to the Distributed Control System (DCS), Hydraulic Power Unit (HPU), and Electrical Power Unit (EPU). The UMCS will communicate with subsea control pods at the wellhead from multiple subsea equipment providers, without disrupting the subsea vendor’s native communication protocol. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Universal Master Control Station」の詳細全文を読む スポンサード リンク
