Remotely Operated Vehicle

The largest and most equipped Remotely Operated Vehicle at the University of Gothenburg descends to 1000 metres depth. It has cameras, sampling equipment, several instruments measuring in the water column and positioning system. V8 Offshore is used on larger research vessels.

A Remotely Operated underwater Vehicle (ROV) is connected via a cable to a ship. From a control room on board, a pilot controls the ROV and its equipment. With cameras and via the cable, we can show moving images and still images in real time on board while recording. ROV is useful in education, research and outreach activities.

With ROV you can reach great depths, to observe, take samples and film for hours, which is not possible through diving. Our ROV have a manipulator arm that can deploy, move or collect various objects. There are also other equipment for biological sampling and sensors to collect information on sea water and seabed.
