The oil and gas sector is one of the key sectors in which we use technology to provide a solution for our clients. In June 2016, our team of specialists were recruited by Quadrant Energy – one of Australia’s leading oil and gas companies.
As a global leader in metocean and environmental survey services, and specifically in the deployment of autonomous glider platforms, Blue Ocean Monitoring was appointed to collect data on site.
Our glider platforms use either buoyancy (sub-surface) or wave (surface) motion propulsion mechanisms rather than drive a conventional propeller as in the AUV family of vehicles. This results in the ability to collect large high-resolution datasets (in near real-time) continuously over much longer periods of time.
The glider sensor payload is customised to the requirements of different projects we are involved in. The near real-time data is then transmitted via satellite to our control and data processing centre. Our clients are provided with remote access to the data.
During this project for Quadrant Energy, Blue Ocean Monitoring slocum gliders captured over 22 million data points. There were a number of factors involved in the company’s decision to use Blue Ocean Monitoring.
Changes in current directions, high current velocities and tidal cycle movements meant that the implementation of fixed moorings, or conducting a vessel based survey, would not profile the area accurately. It would also not have been a cost effective method.
Quadrant Energy appointed our team of metocean specialists to deploy and operate an autonomous underwater glider for 45 days. Our role was to collect data during baseline, operational discharge and post discharge.
Our slocum gliders proved to be cost effective. Using technology was hugely beneficial in its ability to use its real time current measurements to ensure profiling was taking place downstream of the prevailing current.
Our specialists continued to monitor oceanographic and optical water quality properties. Our gliders were monitoring and gathering data 24 hours per day, for 45 days, over the full water column with a sampling regime of two seconds.
