MacArtney upgrades MMT's ROTVsVessel & ROV News // May 2, 2014
MacArtney has completed an upgrade of two Focus-2 ROTV systems belonging to Swedish marine survey contractor and specialist MMT.
Both vehicles have been fitted with new equipment to carry out geophysical survey missions for clients within oil, gas and renewable energy industries.
Complementing the sidescan sonar and sub-bottom profiler already onboard, the ROTVs have been equipped with a multibeam echo sounder, an inertial navigation system and a doppler velocity log.
These upgrades entail that a complete subsea geophysical survey can be carried out at a speed of 6 knots and down to a water depth of 400m, with the onboard MacArtney control systems and software working to ensure vehicle stability and optimal data gathering conditions.
