Moving Vessel Profiler™
- An Underway (Instride) Ocean Profiling System
The Moving Vessel Profiler™ (MVP™) is a multi-purpose instrument for aiding in the collection of both shallow and deep water data sets. The MVP™'s primary function is to allow accurate data collection without the need to stop the vessel.
![]() The system includes a computer-controlled smart winch and deployment system that allows the free fall fish to be deployed while the vessel is underway. The system is completely autonomous and can be controlled by computer without the requirement for personnel on deck. This serves the purpose of extending operations by not relying on deck crew after normal working hours and also through the expanded environmental operating envelope.![]()
The system was originally adapted to collect Sound Velocity (SV) data for shallow water (to a depth of 100m) hydrographic operations. The data was used to calibrate multibeam sonar data for the Canadian Hydrographic Service.

The Free Fall Fish designed for use with the MVP™ system can carry a variety of sensor packages. Sensors that have been used with the MVP™ system to date include Sound Velocity, CTD, Laser Optical Plankton Counter (LOPC) and fluorometer.

The following shows the major components of the MVP™ system. The computer controls the winch using parameters set by the operator, the depth signals sent back by the free fall fish and (if the vessel is equipped with one) readings sent to the MVP™ controller by the ship's depth sounder. The data is collected in real time from the fish and recorded by the computer in a format that can be presented graphically. Click on the various parts of the graphic to view larger images.

The animation above shows the MVP™ deployed from a typical vessel collecting three sets of profile data while underway. Click here to see an enlarged view of the animation.
![]() An MVP™ profile to a depth of 100 metres would take four (4) minutes from deployment to recovery.
![]() Things to note are the programmed bottom avoidance, the near-vertical free fall and the fact that the fish does not break the surface while underway. Please note that the elements of this animation are not to scale.
![]() The illustration to the right shows the path of the Free Fall Fish for a typical cast. The sequence of events for a typical cast is:1.) deployment, 2.) freefall, 3.) maximum depth 4.) retrieval. ![]() The MVP™ system allows repeated deployment of the fish for as long as necessary to compile a complete data set (see an example described in the February 1998 Press Release). The narrow red band behind the ship indicates the small amount of area necessary to operate the MVP™ system (approximately 1 metre²). This would allow it to be used simultaneously with applications that require a number of towed objects behind the vessel.

The free fall fish used with the Moving Vessel Profiler comes in a number of different shapes and sizes, each specifically designed for use with a particular depth and sensor configuration.
