ORION is our flagship product for offshore utility survey and includes our new MultiSens™ technology. It is available in two, four, and six sensor configurations for high-fidelity tracking of underwater cables and pipelines. ORION can be mounted on various platforms, including sleds and ROV's, and is rated to a depth of 2000 m.
LIBRA is a replacement for Optimal Ranging's FieldSens underwater surveying equipment. Like FieldSens it is designed to be towed by a boat or other vessel from the surface and may also be fixed-mounted directly on the vessel.
Both systems are integrated with leading hydrographic survey software including EIVA, QINSy, and HYPACK.
The ORION and LIBRA underwater utility survey systems both bring the power of model-based processing to cable and pipeline Depth of Burial (DoB) surveys. The method is based on the optimization of data from multiple sensors against a model of the magnetic field expected from a utility line carrying an AC tone (actively applied or passively present). System accuracy is estimated and presented in real-time.
Magnetic field distortion due to co-linear underwater conductors can occur when multiple pipelines share a right of way, or multiple wind farm power cables are closely spaced at landfall. Both systems self-identify these errors and presents them as confidence intervals on the measured Depth of Burial. In the 4 or 6 sensor MultiSens™ configuration, ORION can decouple this distortion from the target pipeline or cable, resulting in a more accurate Depth of Burial estimate, with an improved confidence interval.
The ORION and LIBRA sensor arrays only needs to be brought in the approximate vicinity of the utility line to calculate a relative position. Using at least two 3D magnetic field sensors, a triaxal accelerometer and digital compass, The systems identify the horizontal offset, vertical depth, tone current strength and yaw angle to the buried utility regardless of its position and relative orientation in the radiated magnetic field. ORION and LIBRA can be controlled and interrogated using standardized NMEA commands over a serial data link using RS485/RS232 protocol. ORION also supports system control and data acquisition over an ROV's local area network.
Utilities and surveyors note:
Our Spar products are available from many Trimble survey distributors in the US, Europe and elsewhere. Orion and Libra are available from various distributors as well as directly from Optimal Ranging.
