MATTRESS INSTALLATION MONITORING
OASYS it’s object recognition capacity is perfect to monitor the position of objects in the water column. The installation of subsea protection mattress is a perfect application:
- The position, altitude and rotation of the mattress frame is tracked instantly and compared with the target laydown position in order to provide correction values
- An installed mattress can be surveyed instantly and its location can be used for the installation of the consecutive mattress
- The system is vessel-fixed and therefore not influenced by current flow velocities
- Reduce dependency of ROVs when the OASYS is combined with a remote release system on the mattress deployment frame
ASV-based
Boulder clearance / trenching monitoring
Use OASYS from an ASV to monitor plough-based boulder clearance / trenching operations. Key benefits:
- Monitor the position, heading and orientation of the plough in real-time and compare it with the target route
- Perform quality-control on the plough performance as disturbed seabed profile and rock berms are directly visible
- Get a direct indication of the plough’s scouring depth
