When a large North Sea operator needed two rapidly deployable pressure loggers to meet an imminent offshore mobilisation, they turned to Aquatec Group for a turnkey service. 

Aquatec engineered a pair of ROV-deployable magnetic mounts to allow two of their AQUAlogger® 310 oceanographic pressure and temperature data loggers to be mounted directly onto subsea cross braces on a North Sea platform at two separate depths. 

Aquatec delivered the pre-programmed instruments, which needed just a simple magnetic actuation prior to deployment subsea to trigger logging.  Both units have a “shake-to-show” feature which allows the user to see if they are logging before deployment via a useful LED indication.

The loggers are now recording wave-induced pressure variations to provide insight into the coming season’s dive operations, which will be carried out with new dive equipment.  After the logging is complete, Aquatec’s engineering team will download and report on the logged data when the instruments are retrieved.
