VetcoGray SemStar5*

This fifth-generation subsea electronics module draws on our field-proven technologies based on more than 30 years of subsea experience. Ruggedized to exceed ISO 13628-6 2006 requirements, the radical new design optimizes flexibility, durability, reliability and obsolescence mitigation.

Since its unveiling in November 2008, the VetcoGray SemStar5™ has been critically acclaimed, including receiving a Spotlight on New Technology Award at the Offshore Technology Conference (OTC) 2009.

Features & Benefits

Flexible Communications. An internal Ethernet data bus supports TCP/IP with flexible subsea communications options.

Proven Durability. Extensively qualified beyond the requirements of ISO13628 Part 6 2006. Highly accelerated life testing (HALT) program validates ruggedness and reliability.

Enhanced Reliability. Key features focus on reliability: Single board computer, reduction internal wirings, simplified press fit connectors, built-in diagnostics for each functional circuit board, and redundant internal power and communication busses.

Obsolescence Management. Offers backwards compatibility for legacy subsea electronics modules and built-in obsolescence management strategies for electronic components.

Industry Standard Interfaces. Meets and exceeds industry standard SIIS (Levels 1, 2 and 3) and IWIS.

Application

The VetcoGray SemStar5 subsea electronics module offers architectural flexibility for a variety of production control system applications:

Use as a SEM in a subsea control module (VetcoGray ModPod).

Use as marinized SEM to support remote interfaces and provide flexible system architectures (SemStar5-R).

Use the SemStar5's architecture in communications electronic modules (CEM) to provide subsea communication router (a patented solution) capability along with smart power distribution features.
Regional Considerations

The VetcoGray SemStar5 is designed to handle the broad range of extreme subsea conditions encountered across the globe.

Available for use in any oil field in the world, including long offset oil fields Operates in shallow or deep water Functions well under low or high temperature conditions
Design

The VetcoGray SemStar5 was designed to optimize communications flexibility and reliability.

Flexible Communications. Flexible subsea communications options are provided by: Fiber-optic modems, DSL modem, RS-422 interface, Variable-speed copper modem (VSCM), Low-speed copper modem (LSCM), IP enabled, Plug-and-play subsea LAN

Enhanced reliability. Redundant DC power supply to internal modules, Redundant ethernet, Single-board computer QNX , Robust internal electrical harness design, Fewer internal wiring interconnections needed relative to earlier generations, Simplified motherboards, Built-in diagnostics for each functional circuit board, Fault-tolerant input/output (I/O) interfaces
On-site Capabilities

Virtually all subsea controls products including VetcoGray SemStar5 are designed, manufactured, and tested at our controls and informatics center of excellence, in Nailsea, U.K. This is the primary location for subsea controls project management, engineering, quality , procurement, manufacturing and testing functions .
Testing Capabilities

Wiring Inspection. A complete inspection of all joints, fittings, wires and motherboards is performed to; IPC 610/620 class 3 regulations.

Vibration Testing. During full functionality testing, all three axes of the SEM are vibrated and qualified to the latest ISO standards. Electronic unit shock tests can also be performed.

Temperature Testing. During full functionality testing, the SEM is thermally tested and qualified to the latest ISO standards; 24-hour temperature cycling is followed by a 48-hour burn-in period.

Full Functionality Testing. Automatic test equipment simulates all inputs and outputs of the SEM during functional testing.

Hyperbaric Testing. The SEM vessel undergoes hyperbaric testing communicated through the top of the pressure vessel.
Customization

The VetcoGray SemStar5 is a fully modular fifth-generation subsea electronics module designed with compatibility, durability and flexibility in mind. It employs open architecture communications and supports future oilfield topologies and architectures, while maintaining backward compatibility with GE's other subsea electronics module (SEM) products.
