  1. i - Intelligent V - Valve P - Pack

  2. iVP Function • The iVP is an integrated family of components offering: • Operation at depths up to 3000 metres. • Remote control of hydraulic and electrical equipment. • Collection and transmission of instrumentation datafrom the remote location, including video. • Function control, data display and storage at a controlconsole. • Available from stock parts – fast deliveries.

  3. iVP Family

  4. iVP Applications • Remotely operatedvehicle (ROV) equipment. • Intervention tooling equipment. • Remotely operated tools (ROTs). • Manifold, pipeline & other underwater structures. • ROVs requiring additional or upgraded capability (e.g. 5-function manipulator enhancement). • Tether Management Systems (TMS).

  5. Major component options • Valve Pack hydraulic modules for flow & pressurecontrol. • Valve Pack electronics module. • Simple Power Pod for valvepackpowersupplies. • Intelligent Power Pod for enhancedpower & control.

  6. System Block Diagram Showing All Major Options.

  7. Valve Pack physical • Lightweight aluminium construction, fully optimised to reduce size & weight • Modular design – configured for only the required number of functions. • Oil-filled pressure compensated internals (including electronics) – with depth rating of 3000 metres. • Hydraulic connections to suit host system requirements. • Hard anodised and CP bonded for corrosion protection. • Module lids removable quickly & separately for fast service. • Orientation insensitive.

  8. Typical iVP configuration

  9. Hydraulic Features • Modular design - 2, 4, 6, 8, 10 or 12 valves per valve pack. • Proportional directional valves give flow control from surface duringoperations withoutthe need for fixed flow throttles. • Flexible hydraulic specification offering: • Proportional or fixed flow directional valves in 2 flow sizes. • 1 or 2 separate pressure inputs, up to 315 bar. • Pressure control stages. • Service line relief valves for actuator / equipment protection. • Optional pilot operated check valves. • Optional hydraulic pressure transducers.

  10. Electronics features • Embedded processors for instant boot-up and reliability. • Integrated communications link over 5.5km of twisted pair. • Software configurable mapping of console inputs to remoteunderwateroutputs (valve pack or power pod). • External sensors on both valve pack and power pod are supported(e.g. analogue, digital, CP, tacho, Torque Transducer). • Integrated embedded PC in console for display and user interface. • Video text overlay built into console. • System settings can be stored for configured operations. • Task specific settings can be saved and recalled. • Scaleable and upgradeable control system – from ‘dumb’ valve pack tocomplete control system. • Fully self contained system that does not rely upon the use of external computers.

  11. Available iVP Modules • Electronics Module. • NG3 Directional Module. • Pressure Reducing Module. • NG6 Directional Module. • Torque Control Module. • Relief Valve Modules. • Mid Section Blanking Plate. • End Blanking plate.

  12. Electronics Module • Proportional control of up to 12 directional valves & 1 pressure reducing valve. • +24V DC power input (700mA per valve). • External sensor interfaces as standard (analogue 12 & 16 bit, digital, water ingress) • 2 x Torque Tool sensor interfaces (turns, RPM & torque – software calibrated). • Optional depth transducer. • Fully protected circuits & status display LEDs • Embedded processor & integrated telemetry with Console and iPP. Full diagnostics.
