Continuous Five-Day Met Ocean Data And Bathymetric Surveying - Case study
Data Xplorer conducted a five-day continuous voyage throughout the Southern Gulf Islands. The USV was tasked with the dual mission of continuously collecting meteorological data and conducting several bathymetric grid surveys in different locations. The continuous nature of the mission meant the vessel could not be recharged, and would have to rely solely on solar input and battery reserves. Data Xplorer was launched from a boat ramp near Victoria, BC, and began the mission by voyaging 61 km non-stop to waters off the De Courcy Group.
- Demonstrate the use of Data Xplorer for continuous multi-day missions
- Test the USV’s capability to operate simultaneously as both a mobile data-collection buoy and a survey platform .
- Provide real-time QA and remote operations for over the horizon control
Data Xplorer voyaged continuously for 115 hours traveling 167.5 km. During this time it continuously collected an array of data in a range of weather conditions and sea states. At the end of the mission, the batteries still had 50% reserve capacity. Our new generation boats use thrusters requiring half the power, and it can be expected that overall efficiency will be even better.
Data Xplorer was launched from a boat ramp near Victoria, BC, and began the mission by voyaging 61 km non-stop to location near the De Courcy Group. Once in position, the vessel remained in proximity to Ruxton Island with the primary objective of collecting met data, including temperature, wind speed and direction, barometric pressure and solar levels. Additionally, water temperature and depth were recorded.
The USV was controlled from over the horizon using LTE communications, and vessel missions alternated between loitering, patrolling and conducting grid surveys. Grid surveys were performed for bathymetric mapping, and were conducted in two areas of interest near Ruxton Island.
A final grid survey was conducted in Mill Bay, about half way along the vessel’s return voyage to Victoria. The USV performed reliably for the duration of this voyage, and demonstrated itself to be a cost-effective and easily-deployable mobile sensor platform.
