Savante's subsea laser technology can be operated using micro-ROVs for fast first response platform inspection.


Suppporting Micro ROVs with 3D underwater laser and photogrammetry measurement

Micro ROVs offer significant cost and deployment advantages in a variety of inspection applications and scenarios.  In the oil and gas industry in particular, operators realise significant cost savings using a single micro ROV inspection system to provide first-response site investigative cover for platforms in the event of isolated inspection requirements.  Micro ROV inspection systems can be deployed as luggage on helicopter transport, enabling a fast first-response.

Micro ROVs are commonly limited in capability to the provision of video footage; the limited communications capacity of thin tethers makes provision for sensor expansion difficult.  Large, bulky third-party sensor payloads often diminish the maneouverability of the vehicle. 

Laser image scaling to Photogrammetry and Dynamic Laser Mobile Mapping

Savante's subsea 3D laser and photogrammetry technologies have been succesfully miniaturised and optimised for use with a variety of micro ROV vehicle manufacturers.  At the lowest level of complexity, laser arrays or line projectors such as APEX, Aquantum or LMNI modules have been used to provide an indication of scale with video or digital stills footage provided by the existing ROV camera.

The SLV-30, latest mini CTS-3D, Cerberus and Vergence subsea laser inspection tools can also be deployed with most micro ROVs; these are suited for IRM weld and crack inspection, laser profiling and 3D modelling.  Where tether capacity is an issue, Savante's nucleus subsea PC can provide onboard digital recording capabilities using credit-card sized PC technology.
