Provision of Acoustic Current Doppler Profilers at 300kHz

The contract is for the procurement of a medium-frequency 300 kHz Acoustic Doppler Current Profiler (ADCP), capable of fulfilling the requirement of long-term deep-water mooring research. The ADCP purchased is designed to measure ocean currents in open-ocean conditions and can measure currents over a range of approximately 154 meters when configured in long-range mode.

Additionally, the ADCP is capable of self-logging data using its internal memory, enabling it to record measurements independently during deployment without requiring a continuous external connection. The ADCP is rated for operation of up to 6000 metres.

It is fitted with built-in sensors for temperature, tilt, compass heading and pressure, allowing it to collect both current measurement data and supporting environmental or positional information. To support NOC's use of the ADCP, the supplier has provided warranty extensions, bringing the total warranty period to four years.
