Automatic pipelay touchdown monitoring
The best of both worlds: combine OASYS’ automatic object detection capabilities with the cost-effeciency of an autonomous survey vessel.
Positioning OASYS above the pipeline’s touchdown point allows it to continuously monitor the sagbend section of the pipeline. Sagbend coordinates as detected automatically by OASYS are combined with the PLV’s stinger tip coordinates in order to create a mathematical model of the pipeline.
In water depths up to 100m, OASYS can be installed directly on an autonomous survey vessel. In deeper water, OASYS is lowered from the survey vessel to 50m above seabed level.
