Autonomous saildrones out and about
Through the GipNet Environmental Monitoring Research Initiative, CSIRO are trialing the use of a saildrone, a type of Unmanned Surface Vehicle (USV) to collect a range of oceanic data in Bass Strait.
The saildrones are controlled remotely through satellite communications and are powered by wind and solar. They are also equipped with navigation lights, radar reflectors and an Automated Identification System (AIS) beacon to help prevent collisions. The saildrones are approximately 7m in length and 4m in height and have an average speed of around 3 knots (max 8 knots).
They have been equipped with advanced monitoring technology, capable of measuring a range of parameters include carbon dioxide levels in the water. Data collected is being sent back CSIRO researchers in near real time.
The saildrones are designed to travel anywhere in the ocean. Vessel controllers simply plug in coordinates of the area to be monitored and the saildrone makes its way there using its ‘sail.’ Monitoring and communications are powered by an inbuilt solar unit. Each vessel can stay offshore for extended period of time (up to twelve months) without returning to land.
A saildrone is being trailed in Bass Strait to test a range of sensors that ensure this type of platform is reliable, durable and accurate for future monitoring of ocean properties and proposed carbon storage sites. If you see a saildrone, marine users are asked to stay 500m away from the system.
