1 Tittel Unique technology for 3D integrity monitoring of subsea pipelines av Navn Well and Subsea Integrity Workshop October 26, Rio de Janeiro Trond Olsen President, ClampOn, Inc.

2 From the start... WE BUILT A FLOW RIG BUT THE PLUMBER WANTED 5 USD, AND WE DID NOT HAVE THE 5!!!

3 into today Non-Intrusive Ultrasonic Intelligent Sensors - Sand Monitoring - PIG Detection - Leak Monitoring - Vibration Monitoring - Well Collision Detection - Wall Thickness Monitoring - Corrosion-Erosion Monitoring - Onshore, topside & Subsea - Service / Support

4 The Acoustic City Bergen Statoil Christian Michelsen Research (CMR) Bergen University College campus Haukeland University Hospital New R&D park at Marineholmen University of Bergen Companies: ClampOn AADI (Xylem) KTN Halfwave Naxys (GE) Fluenta AGR Pipetech BTC Archer Xsens Octio Kongsberg Maritime CGG Veritas Roxar(Emerson) Tracerco METAS CodaOctopus Simrad/Simtech Subsea Wema Institute of Marine Research Major local users of acoustic technologies and products; Statoil, Schlumberger, Baker Hughes, Aker Solutions, FMC Technologies, OneSubsea, DOF Subsea, Royal Norwegian Navy, Haukeland University Hospital

5 Differences Rio de Janeiro - Bergen

6 Similarities Rio de Janeiro - Bergen

7 Bergen where we keep the head of the Bacalao

8 CEM Product

9 If you have issues like this

10 you could be facing Abkatun-A, Mexico corroded gas line

11 Your challenge Difficult access assets Inaccessible sections of pipelines Unpiggable pipelines Estimation of corrosion/erosion rates for life management Avoid shutting down production to inspect Paradigm shift From random inspection to continuous monitoring License to operate demonstrating safe operations

12 What we bring to the table CEM Monitoring based on GWT w/tomography Non-intrusive permanently installed corrosion/erosion monitoring technology providing a cost-efficient solution

13 Why guided waves Conventional manual gauge Limited spot coverage Guided wave transducer rings Full volume coverage

14 Transducers can be mounted on the outside of coating <1mm /.4 thickness Measures WT between the transducers in line of sight Resolution/sensitivity better then 1% of WT Signal is Robust and will not break down

15 Transducers can be mounted on the outside of coating <1mm /.4 thickness Measures WT between the transducers in line of sight Resolution/sensitivity better then 1% of WT Signal is Robust and will not break down

16 CEM Coverage Area w/gwt 5 signal paths per transducer direct, clockwise and counter clockwise helical and 2 turn helical Max distance is 5 x OD - Min distance is 2 x WT

17 CEM Proving the technology

18 Tomography Results w/edm Defect #1 EDM = Electrical Discharge Machining A copper electrode was machined to pipe surface shape and we eroded out in 12 different steps with increasing steps of 2um, 4um etc steps Defect #12

35 CEM Field examples

36 FPSO Skarv Norwegian Sea Corrosion-Erosion monitoring Particle monitoring Vibration monitoring

37 Topside CEM at BP Skarv FPSO

38 Åsgard/Mikkel/Midgard Compression

39 Siakap-North Malaysia Siakap-North

40 Pre-installed CEM

41 Data Communication via Wave Glider Surfboard The Corrosion-Erosion Monitoring System System in the field - SubseaBrownfield retrofit for GoM project

42 Onshore Application Examples Straight pipes Bends Up to sixteen transducers mounted on two clamping bands over the selected area. Up to sixteen transducers mounted on separate sides of a bend, monitoring the wall thickness loss in the bend. Reducers Up to sixteen transducers mounted on selected locations on the reducer. Uneven thickness profile is not a problem.
