Gyro Compatt 6+ Positioning LBL Transponder
Gyro Compatt 6+ is the latest generation of our combined LBL transponder and AHRS, providing high update rate wireless attitude, heading, heave, surge, sway, temperature, pressure, SV and acoustic positioning of any subsea object. Deep water structure installation - made easy.
Gyro Compatt 6+ replaces the need to use a separate LBL positioning transponder and subsea gyro to support offshore construction campaigns. Using it, structure position and orientation can be accurately determined during lowering, set-down and as-built surveys, while for metrology, the instrument delivers the measurements required for pipe-end coupling.
By eliminating the cost and complexity associated with separate instruments, connected by vulnerable subsea cables and external battery packs, Gyro Compatt 6+ delivers significant operational benefits, saving vessel time and de-risking complex, deep water construction projects.
This, our third generation Gyro Compatt, shares the same field-proven mechanical design as previous models so there’s no need to adapt your existing survey tooling. It’s small and light enough to be installed by ROV, and a mechanical stab plate enables users to precisely align the unit to structures such as templates and manifolds.
It’s on the inside where Gyro Compatt 6+ differs from previous models. It operates using our exclusive Wideband 3 signal protocols so now, for the first time, sensor telemetry data (e.g. pressure, depth, temperature) can be embedded within navigation (ranging) telemetry data.
Using Gyro Compatt 6+ makes pauses in tracking to get sensor reading updates at vital moments a thing of the past.
Fusion 2 LBL software is the key to unlocking the benefits of Wideband 3. Only operations controlled with Fusion 2 are able to support Wideband 3 telemetry commands. Gyro Compatt 6+ transponders are backwards compatible with your existing Compatt 6 inventories. However, to achieve it’s full potential, you’ll need to use exclusively 6+ transponder arrays and Fusion 2.
Compatt 6+ Plus are available to purchase from Sonardyne, or hire from leading offshore equipment rental companies.
