Subsea Production Control System Engineering...

Subsea Production Control System
SUBSEA ISOLATION VALVE SYSTEM
SSIV
Subsea Production Control Systems (SPCS) have to be designed, tested and commissioned with Technical Integrity. Critical elements of SPCS that are reviewed by Nexus are:
  1. Fluid Power: Water-glycol based control fluid conforming to high cleanliness standards is needed to OPEN and CLOSE subsea actuated valves, SCSSV and SSIV (where applicable). This is supplied by the Hydraulic Power Unit (HPU).
  2. Electrical Power: this s is needed at the Subsea Control Module for powering electrical and electronic equipment including sensors and detectors. This is supplied by the Electrical Power Unit (EPU).
  3. Communication: Data exchange is achieved  from the MCS through TPU's via Fiber Optics the Subsea Control Module.
Do you have a SSIV (Subsea Isolation System)  that needs to be reviewed? Typical SSIV Systems requires, as a minimum, HPU, TUTU, Control Umbilical, SUTU, Flying Leads and topside ancillary tie-ins and equipment. Are you looking to derate a HPU HP line when selecting a Depth Star SCSSV? Do you have a need to Review your Hydraulic Power Unit Schematics? Are you encountering Operational Problems with your Regulators? Do you have a need for designing and fabrication a HPU or Topside Umbilical Termination Unit / Assembly (TUTU/UTP/TUTA)?
Our expertise in Subsea Production Control Systems gives you access to the following:
  • Subsea Distribution (UTA/SDU/UTH, HFL, EFL, EOFL)
  • Developing Shutdown Logic
  • SCSSV Controls via the Subsea Control Module
  • We can help you tie-in your HPU, TUTU, Umbilical and Subsea Umbilical Termination Unit (SUTA)
  • Compensation Methodologies for the Small Bore Tubing
  • Tree Mounted Controls
  • Electrical Power Unit (EPU) and Master Control Station (MCS)
  • Controlling Multiple Pay Zones
  • Subsea Isolation Valves (SSIV) and Riser Base Monitoring

Powered by people, steered by safety.
