Vessel-Mounted Operations
Accommodating situational awareness
Download specification sheet
The VM Operations helps operators on vessels make informed decisions during subsea operations in areas affected by underwater currents. It is designed to give offshore operators clear and detailed information on current speed and direction from the vessel to the seafloor.
- User-friendly software
- In-water serviceable instrumentation
- Salinity-independent velocity measurements
