2iVP 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 data from the remote location, including video.Function control, data display and storage at a control console.Available from stock parts – fast deliveries.
4iVP Applications Remotely operated vehicle (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).
5Major component options Valve Pack hydraulic modules for flow & pressure control.Valve Pack electronics module.Simple Power Pod for valve pack power supplies.Intelligent Power Pod for enhanced power & control.
7Valve Pack physicalLightweight aluminium construction, fully optimised to reduce size & weightModular 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.
9Hydraulic FeaturesModular design - 2, 4, 6, 8, 10 or 12 valves per valve pack.Proportional directional valves give flow control from surface during operations without the 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.
10Electronics featuresEmbedded processors for instant boot-up and reliability.Integrated communications link over 5.5km of twisted pair.Software configurable mapping of console inputs to remote underwater outputs (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 to complete control system.Fully self contained system that does not rely upon the use of external computers.
