Remotely Operated Vehicle (ROV) Genesis

The Remotely Operated Vehicle (ROV) Genesis is an (unmanned) underwater robot that can dive to a depth of 1300 m. Because of the ROV Genesis, visual observations by means of cameras and samples by means of a working arm can be executed on locations that can rarely be explored such as methane sources, cold-water coral reefs or ocean margins. The ROV is controlled by a pilot who follows every action on screens from a container mounted on the research vessel.

How does a ROV work?

The ROV fits in a Tether Management System (TMS) that is placed from a research vessel onto the seafloor. The TMS is a kind of garage for the ROV: once on the seafloor, the ROV sets off for a sampling trip. The TMS and the research vessel are connected through a cable, as are the ROV and the TMS.

The ROV is controlled by a pilot who follows every action on screens from a container mounted on the research vessel. A hydraulic working arm can perform simple samplings. The device is equipped with several lights, with both colour and high resolution video and picture cameras which can film and take pictures and with a laser measuring system. The depth, course, height, swell and slope are continuously registered, as are the temperature and salinity of the water.

Usefulness of the ROV?

  • Using the ROV, samples can be collected in difficult accessible locations/phenomes such as deep sea canyons, cold water coral reefs, carbonate mounds, mud volcanoes, methane sources, etc.
  • ‘Hotspots’ of life are commonly discovered in sometimes extreme environments. Such hotspots contain life forms that are sometimes completely new for the science. The ROV is an ideal research instrument to discover such hotspots.
  • Real-time visualisation at great depths.
  • The ROV Genesis is also deployed from the RV Simon Stevin for scientific campaigns in the Belgian part of the North Sea. Both the RV Simon Stevin and the ROV are fit for shallow coastal water: to take bottom cores, investigate shipwrecks or to map the sea bottom.
