Ocean Modules V8 Sii ROV
The revolutionary V8 Sii (Search, Identification and Intervention) is a remotely operated vehicle is based on eight vectored thrusters and an extremely advanced control system, allowing it complete 360° freedom in all three dimensions. Any desired angle and position can be held indefinitely, at any depth, as required.
Footage of the V8 Sii captured during a training course for new pilots with no previous ROV experience.
Ocean Modules provides an extensive range of fixed cameras, PTRZ dome cameras, halogen lights, LED lights, sonars, manipulators and sensors making the V8 Sii the perfect tool for jobs ranging from measuring the thickness of the Antarctic ice to disposing of mines on ship hulls to inspecting the deep base of oil platforms in the North Sea.
Operator Console Unit (OCU)
The OCU is a PC-based control system fitted with a 15" sunlight readable high resolution display. It is used to run digital recording software for video and sonar capture as well as any applications for any other sensors connected to the ROV. The patented Spot.on software is also run on the OCU for mission planning and recording.
The OCU can also be used on its own as a compact, mobile and completely waterproof ruggedised computer. The ROV system can be operated independently, without relying on the functions of the OCU.
| Depth: | 400mm |
|---|---|
| Width: | 500mm |
| Height: | 200mm |
The SCU is also available as a rack mountable option for permanent installation.
Pilot Control Unit (PCU)
The PCU provides all the controls an operator needs to handle the V8 Sii in one simple handheld unit. These include speed, direction, depth, pitch, roll, trim, light intensity, camera pan and tilt and autopilot. Anyone who has ever played Quake or driven a remote controlled car will instantly understand the intuitive interface.
| Depth: | 240mm |
|---|---|
| Width: | 260mm |
| Height: | 170mm |
Power Supply Unit (PSU)
The PSU provides the power required to operate the V8 Sii ROV. For added safety it includes constant insulation monitoring with a warning LED as well as automatic cut-out.
| Input: | AC - 3kW max |
|---|---|
| Output: | 600 VDC |
| Depth: | 240mm |
| Width: | 260mm |
| Height: | 170mm |
Tether
Ocean Modules provides a variety of cables for use with the V8 Sii ROV. The standard cable is a 13mm neutral buoyancy cable housing power conductors and three twisted pairs for control, video, sonar and other sensors. It is available for lengths of up to 500m and can withstand strain of up to 500kg.
For longer tethers or higher bandwidth requirements a fiber optic option is also available.
Service and Maintenance
The superior reliability and extreme modularity of the V8 Sii ROV allows Ocean Modules to present a new type of maintenance contract. For a low yearly fee an operator enjoys an unprecedented level of service.
If a fault occurs, the operator simply replaces the two electronic pods, the two power pods and any faulty thrusters with a set of spares. No fault finding is required. The replaced pods are shipped back to Ocean Modules for service and testing. A fresh set of spares will be dispatched to the customer immediately. Using this method downtime can be limited to 20 minutes in most cases.
