ROV specifications

 

Since 2012, WavEC has acquired and operated a Seabotix LBV 200-4, an observational class ROV (Remotely Operated Vehicle). The vehicle has the ability to operate in virtually any marine environment down to depths of 200m, well exceeding those of a diver.

Equipment includes:

  • 2 cameras; a low light camera with tilt and focus controls used for navigation; and an external HD camera capable of capture images at 1080p. To collect images at such depths, where natural light is scarce, the ROV is equipped with both internal and powerful external lights;
  • USBL underwater positioning system, allowing to find geo-referenced underwater objects and making transect inspections of the seabed;
  • Sonar system to allow finding objects in reduced visibility conditions;
  • Laser scaling system- which provides a distance reference in all images collected allowing object size to be calculated;
  • A grabber arm, which has the option of a simple grabber or a cutting tool. These can be used to collect samples, release sea bottom mounted equipment and simple manipulation tasks.

The whole system is self-contained and can be supplied to any location and deployed from virtually any boat or platform, allowing unparalleled flexibility.

WavEC also owns and operates additional monitoring systems namely two self recording Marsensing digitalHyd SR-1 hydrophones and a Midas miniCTD probe. The hydrophones can be used to assess the underwater noise produced by any given source such as a renewable energy device (wave, tidal or offshore wind), shipping, construction noise among others. The CTD provides accurate measurements of salinity (through conductivity), temperature and depth to help us observe the structure of the water column and understand the dynamic physical processes of the sea. Both of these instruments can be used in conjunction with the ROV data to provide a more detailed and comprehensive assessment.

Services

Structural inspections

WavEC can provide ROV services for observing and inspecting underwater structures; past campaigns have included:

  • Inspecting underwater offshore energy installations and their components, such as moorings, anchors and electrical connections
  • Ship hull examinations
  • Sea floor cable inspections
  • Shipwreck inspections

Environmental services

The WavEC environmental team can also provide many different ecological services aimed at both wave/wind energy installations as well as a broader range of applications.

Services provided include:

  • Habitat mapping
  • Colonization patterns
  • Scientific sample collection
  • Diver support
  • Benthic surveys
