Ocean Modules V8 Sii ROV
The revolutionary V8 Sii (Search, Identification and Intervention) is a remotely-operated vehicle based on eight vectored thrusters and an extremely advanced control system, allowing it complete 360° freedom of movement in six 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.
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 a first-persion video game or driven a remote-controlled car will instantly understand the intuitive interface.
Surface Unit (SU)
The SU 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. It also has an interface for all the inputs and outputs, such as telemetry, video, sonar, Ethernet, USB and RS-232.
Tether
Ocean Modules provides a variety of cables for use with the V8 Sii ROV. The standard cable is a 12mm 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.
A fiber optic option is also available for HD video, longer tethers and higher bandwidth requirements.
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.
