MEC-FIT™ Flexible Riser Cases


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.

Self crawling MEC – Combi Scanner top site deployed


SUBSEA PIPELINE INSPECTION

MEC Subsea Pipeline Scanning

– on coatings up to 15mm

– fast scanning

– high sensitivity for corrosion detection (pitting or general

corrosion areas

– ROV or diver deploying

PEC Subsea Pipeline Scanning– on coatings up to 200mm

– Static measurement

– footprint measurement – averaging of area wall loss

– ROV or diver deploying


MEC-Combi Crawler for Subsea PipeScan

Self crawling systems with Inspection technology

adaptations : MEC , UT, Visual, Laser, PEC



MEC and UT inspection report, Subsea Pipeline Section



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 “

Subsea Pipeline Inspection

Generation 2 Sensor Units

R&D

Generation 12 Sensor

Units - increasing Scan

speed 6 x


- 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
