Mainstream Biological’s ROVs

What is a ROV?

A Remotely Operated Vehicle, (like a remotely controlled submarine), used for underwater monitoring and exploration.  It allows us to go into waters that may not be safe, or comfortable, for human divers.

What do you use the ROV for?

We use our ROV’s primarily for sub-tidal habitat assessments, including compliance monitoring at Finfish Aquaculture sites.  We also use them to conduct effluent pipe surveys, map eelgrass beds and conduct underwater salvage.  Some recent salvage retrievals include a heli-logging grapple in River’s Inlet and a freighter anchor in Vancouver Harbour.

What type of ROV does Mainstream Biological use?

Mainstream Biological operates two ROV systems, a Seamor 300F and a Seamor 300T.  Both of these ROVs have four high powered, thrusters. These are industrial, inspection-class ROVs. They can handle all types of marine and freshwater environments and have the added benefit of high resolution imagery, intuitive control and excellent portability.


What are some of the features?

Our ROVs are equipped with colour, high resolution cameras with auto zoom, LED light arrays and auto depth capability. We also have a manipulator arm for our ROVs that allows us to grab, hold, and retrieve items. We use a TrackLinkUSBL GPS system to track the ROVs while underwater. The Rov(tracking? Think the Rov is a typo in the original text) allows us to see in real time the location of the ROV and pinpoint the location of habitat, fly exact transects and map the locations of anything we find. TrackLink systems are extremely robust, and known as one of the best in the world for providing tracking and communications with ROVs.The 300F ROV is controlled via 4mm fibre optic tether, while the 300T is controlled via a twister pair tether.  Both ROVs are capable of surveying to depths of 300m (1000ft).
