As part of the continuous refinement of SRD's
Pipe Exit Monitoring (PEMS) and Pipe Lay Support (PLS) systems,
SRD has developed an FPSO riser and anchor chain monitoring system
by adapting its proven acoustic technology.
RAMS comprises a compact sonar array which detects and analyses
returning signals from in-water features at various levels within
the water column. It was designed around the following principal
requirements:

Continuous / long term deployment capability.

Simultaneous measurement of all riser positions.

Simultaneous monitoring of the presence of all anchor chains.

High precision measurement of absolute and relative positions.
The RAMS control and processing software uses specialised range
and bearing calculations to derive precision single point target
positions from the acoustic samples.
