New offshore survey AUV
Kongsberg Maritime’s Subsea Division in Norway reports development of a new AUV accommodating a complete subsea survey payload, called Munin.
Designed for acquisition of high resolution sonar data geo-referenced by a survey grade positioning system, the compact unit is capable of 24 hour missions at depths down to 1500m, assuming use of extra batteries.
Navigation systems and acoustic payload sensors are integrated within a single mechanical housing, which is factory calibrated and requires no re-alignment after transport or re-mobilisation. Equipment includes a customised EM 2040 multibeam sounder and EdgeTech sidescan and forward-looking sonars. Also incorporated is an NBOS conductivity and temperature sensor together with options for a sub-bottom profiler and still image cameras.
