Mobile survey boat
Equipped with high-end survey tools
� High-resolution multibeam
� Sonarhead mounted to tiltable arm
� Laser scanner
� Scanner to be mounted when needed
� RTK positioning
� Latest survey software
Basic inspections for harbour infrastructure for the
benefit of maintenance management
1. Multibeam and low frequency surveys in harbour basin
2. Underwater infrastructure inspections with multibeam
3. Abovewater structure documentation:
Laser scanning, photographing and/or visual inspection

1.
Traditional hydrographic survey compared to infrastructure surveys
� To make hydrographic charts you don´t use all information you can get
from MBES surveys
� To study objects and bottom formations you need to use all benefits of
MBES survey technology
� To get good underwater picture of your quay walls and another
underwater infrastructure you need to use all benefits of MBES survey
technology
� Software typically used for sounding charts (like AutoCad, Microstation
etc.) cannot handle all data available from MBES technology
Port of Rauma
� Around 3,4 km of quay walls in total� Around 30m wide strip of seabed to
be surveyed� Report is based on visual inspection
of post-processed data by engineers
ANALYZE AND REPORTING
1. Underwater objects 2. Scouring, sedimentation 3. Structures
