APOS Survey - Surveyor's independent Operator Station for HiPAP

Subsea survey operator station

Contact us

APOS Survey has been developed to provide a cost effective solution for subsea survey and construction operations, making it possible for the surveyor to utilise a vessel's HiPAP system. Acoustic interrogations are interleaved or run simultaneously with the DP system updates, without making changes to the vessel’s APOS software or installation parameters.

APOS Survey offers full LBL and SSBL, quicker mobilisation times and is designed for both permanent and temporary installation on vessels. The software communicates directly with the HiPAP transceiver, enabling the surveyor to operate independently of the bridge. The software safely integrates into the vessels HiPAP system through a high speed, optically-isolated, serial connection to maintain independence from the vessel's Dynamic Positioning (DP) network, and removes restrictions normally associated with operating a HiPAP system for subsea survey purposes.

The surveyor can interface local survey grade sensors, IMU, GYRO and GNNS, set up lever arms and load velocity profiles independently of the vessel, unlocking the full potential of HiPAP. The cPAP LBL transceiver for ROV positioning and portable HiPAP transceivers are easily interfaced, providing flexibility for a full range of operations. Both the vessels APOS and APOS Survey can compute position off the same SSBL transponders with independent calculation. HiPAP transducer alignment for both the vessel and APOS Survey system can be run simultaneously.
