MoS provides the Scanmachine and Scancrawler operator with a virtual working environment by creating a 3D model of the machine and its position on a terrain model representation
of the work location

The working environment model can be defined based on survey data and a definition of
how the location is to be modified. Existing features/structures can be visually represented as objects in MoS using known coordinates or confirmed by nozzle position. If no survey record exists, the user can define the terrain model and position features (example pipelines, frames) in the work space. The terrain model can be defined by repeatedly positioning the dredging nozzle around the profile of the sea floor.
The progress map is updated continuously based on the area excavated. The coloration of the screen representation visualises the difference between the actual terrain and target model.
Target models can be imported to enable precision work to be performed according to
a predefined target
The system includes interfaces for transponder and gyro information. MoS can reference
the Scanmachine/Scancrawler virtual working environment globally in true world coordinates
by interfacing to the vessels position systems.
The MoS system has proved itself to be a very efficient aid for precision work in close
proximity to subsea assets.
MoS provides operators with the confidence to continue work especially in low visibility
conditions.
The system has been in operation since February 2003.
