There are disadvantages to the hull mount: the head cannot be inspected easily for marine growth
or damage; the vessel may be restricted in the depth of waters that can be surveyed, due to the
head being permanently attached to the hull.
A normal hull mount will also involve the fabrication of a fairing, on the hull, to ensure correct flow
patterns over the sonar head.
3.2.5 ROV Mounting
The Sonic 2024/2022 is ideal for undersea operations due to its compact size and low power
consumption. With all processing being done in the Receive Module, all that is required is to
provide Ethernet over single mode fibre optic communication, between the SIM and the Receive
Module. The 48VDC is supplied via the ROV’s power distribution.
Please refer to Appendix VII for full details on ROV and AUV installation, interfacing and operation.
