Long range hydroacoustic telemetry link
The long range communication link is used for subsea valve control and monitoring over
ranges of up to 15 km. The potential costs saved by using long range links instead
of cable communication are significant.
The topside units for these long-range communication links can be installed in
rigs, platform or vessels. The operator's unit can be integrated with the hydroacoustic
positioning system, or can be installed as a separate system. Typical values monitored
by the link system are pressure, temperature, battery status, valve position etc.
We frequently use a combination of the different systems to obtain maximum performance.
