A spread able to cover the seabed with long range side scan sonar, which would be equipped with several flight recorder pinger locator systems, and be able to recover debris with an ultra-deep ROV. The full spread was permanently fitted on board our vessel SV John Lethbridge, which eliminated long mob/demob times and/or long calibration periods.
- 6000 msw side scan sonar
- 6000 msw ROV
- 6000 msw salvage capacity
- 10 km range USBL
- INS based positioning systems
- Flight recorder locators
Having achieved this, operations were switched from sonar to ROV work without the need for an extra port call, involving demobilisation and remobilization, as all the systems were permanently operational on the SV John Lethbridge and the survey personnel can operate both at will.
- No mobilisation/demobilisation
- No port call required
- Vehicles swap in a minute
