Topside Control Systems

FMC Technologies' Topside Control Systems incorporate design innovations to adjust to the changing demands of today’s subsea environment.

Master Control Station (MCS) - User Configurable Open System (UCOS)
UCOS is the result of a global initiative to create a superior controls system based on standardized components. FMC Technologies’ topside controls systems introduce component standardization to improve execution, accelerate delivery time and maximize return on investment, and features hardware-independent software solutions to improve the long-term cost of ownership.

  •  Topside master control station providing a user interface, alarm management, data historian, safety critical functions
  •  Condition performance monitoring
  •  Hardware independent
  •  Proven industry track-record
  •  Simple interface – turnkey integrated solution
  •  Automated configurations
  •  Security – cyber security independently audited

Subsea Power and Communication Unit (SPCU)
FMC Technologies’ Subsea Power and Communication Unit (SPCU) connects to the SCM; its modular design improves the ability to upgrade the power and communications hardware and software as technologies and system requirements change. This design adds greater reliability and flexibility as well as ease of service and maintenance.

Hydraulic Power Unit (HPU)
FMC Technologies’ Hydraulic Power Unit (HPU) provides redundant low and high-pressure hydraulic supplies to the subsea system. The self-contained and totally enclosed HPU operates autonomously under the control of its dedicated programmable logic controller (PLC), which provides pump motor control, interlocks and interface with the MCS.

Topside Umbilical Termination Assembly (TUTA)
The Topside Umbilical Termination Assembly (TUTA) provides the interface between the main umbilical and the topside controls equipment. The unit is a free-standing enclosure that can be bolted or welded in a location adjacent to the umbilical hang-off in a hazardous, exposed environment onboard the topside facility.
