North Sea Case : Wire Crack Detection of 55 degree Wire Flexible Riser
Flexible Riser set up: armour wire SCC verification tests
MEC-FIT™ Flexible Riser Cases
Target of the technique verification to detect tight
cracking in single wire with expected orientation of 45°
and 90°to the wire cross section.
Cracking to be detected on the inner wire & outer wire
layer.

Subsea PEC Deployment
The SUBSEA PEC is a static measurement with capability to inspect through up to
200mm stand off (coating). Two sensors are guided to scan circumferentially and
axially along the pipe. Pipe Diameter Range 8” – 36 “

- MEC Combi Crawler Robot Hull Cleaning & Inspection Robot with top side deployment
R&D and Equipment Production
- Top side deployed Crawler Inspection system with integrated thrusters, replace ROV /
diver requirement
- Splash Zone cleaning & inspection system with automatic operation (avoid RAT
requirements : therefore less weather dependent & clamp/guide passing
