2 Lloyd’s Register Energy - Drilling Agenda Introduction Fiber Bragg Gratings Explained Examples of Asset Integrity Monitoring in the Nuclear and Wind Energy Sectors Discussion of a Riser Tensioner Monitoring System Installed on the Discovery Luanda Discussion of an Instrumented BOP at the West Tech

3 Lloyd’s Register Energy - Drilling Introduction Fiber Optic Sensors have been widely utilized in Structural Health Monitoring (SHM) for more than 10 years now. Main applications include: Civil Structures Trains Marine – LNG Ships, Composite Hulls Energy – Wind, Nuclear, Hydroelectric, Oil and Gas. Aerospace Geotechnical

4 Lloyd’s Register Energy - Drilling Fiber Bragg Gratings Explained

5 Lloyd’s Register Energy - Drilling Fiber Bragg Gratings Explained A Fiber Bragg Grating is a periodic change of the refractive index in the core region of an optical fiber.

6 Lloyd’s Register Energy - Drilling Fiber Bragg Gratings Explained

7 Lloyd’s Register Energy - Drilling Fiber Bragg Gratings Explained Each grating sensor is at a different fiber location and allocated a separate central wavelength and spectral operating window band.

8 Lloyd’s Register Energy - Drilling Advantages of Fiber Bragg Gratings Immunity to electromagnetic interference (EMI) and electrical discharge (lightning). Passive operation, intrinsically safe. Water and corrosion resistant. Excellent resolution and range. Rugged, small size and light weight. Small size allows for insitu measurements. Multiple sensors per channel. Absolute measurement. Low signal loss, sensors may be interrogated for many kilometers. Signal conditioning equipment has a much smaller foot print.

14 Lloyd’s Register Energy - Drilling Examples of Asset Integrity Monitoring 3.5 MW Clipper Liberty Wind Turbine

15 Lloyd’s Register Energy - Drilling Installation of Robert E Ginna Nuclear Plant NEMA 4 Enclosure with splice tray. Instrumented Tendon Os3600 surface mount concrete strain gage and instrumented rebar, located on containment structure just below roof line Roof penetration to instrumentation rack located in room below the roof.

16 Lloyd’s Register Energy - Drilling Installation of Robert E Ginna Nuclear Plant A fiber optic strain gage was applied to a currently exposed hoop direction rebar. A fiber optic concrete strain gage was installed 6” (15 cm) below the rebar excavation in the hoop direction. These gages are monitored in the same DAS as the tendon monitoring system Rebar and Concrete Strain Monitoring

17 Lloyd’s Register Energy - Drilling Installation at Robert E Ginna Nuclear Plant Shim and tendon with sensors installed for a total of 20 instrumented tendons.

19 Lloyd’s Register Energy - Drilling Discussion of A Riser Tensioner Monitoring System Installed on the Discovery Luanda

20 Lloyd’s Register Energy - Drilling Overview Meet API 16Q requirements for a more accurate determination of the reduction factor. Need to measure full system load, current system measurements based on hydraulic pressure. Long term Reliable Intrinsically safe operation. Quick implementation and ease of installation. Provides for remote monitoring and maintenance capability.

22 Lloyd’s Register Energy - Drilling Tensioners of the DSL

23 Lloyd’s Register Energy - Drilling Sensor layout for two tensioners

24 Lloyd’s Register Energy - Drilling Protection wrapping of sensor locations for transportation to the DSL. Surface preparations and sensor installation.

25 Lloyd’s Register Energy - Drilling Sensor locations after tensioner installation on the DSL. Each tensioner has 3 os3155s 120 degrees apart in the axial direction. Each tensioner has 1 os3200 in the hoop direction to measure pressure.

26 Lloyd’s Register Energy - Drilling Equipment Rack

27 Lloyd’s Register Energy - Drilling Acquisition rate is 10 Hz X Axis represents approximately 2.41 minutes of data Y Axis = Strain Waveforms confirm a swell period of ~ 12.5 seconds correlating to ships weather

28 Lloyd’s Register Energy - Drilling Conclusion/Discussion Sensors were installed in the Bosch Rexroth facility in Uden Netherlands in September 2012. System was commissioned in May 2013. Sensors were damaged during transport and installation. Sensor protection not robust enough. Despite damage, enough survived to acquire loads on each tensioner. Redundancy in built-in system installation allows for sensor recovery. Real time calculations and display are within 5% of modeled loads.

29 Lloyd’s Register Energy - Drilling Discussion of an Instrumented BOP at West Tech

30 Lloyd’s Register Energy - Drilling Overview LRDIS has instrumented a BOP on site. We are able to detect the pressure inside the BOP bonnet from a hoop oriented strain sensor. Also detect dimensional changes in the bonnet due from an axial mounted strain sensor. Allows us to infer correctly, pressure and operation – The position of the RAMS, Fluid flow Solenoid operation Regulator operation Choke and Kill Lines Fail-safe Valves Pre-charge on Subsea Accumulators Etc.

31 Lloyd’s Register Energy - Drilling BOP Pipe Ram Located at West Tech

32 Lloyd’s Register Energy - Drilling Gage Locations Hoop Gage Pressure Axial Gage Pressure

33 Lloyd’s Register Energy - Drilling Software Has Been Developed to Replay Data for BOP Operational Demonstration

34 Lloyd’s Register Energy - Drilling Hoop gage responds During cylinder pressurization. Axial gage responds after rams engage. Acquisition rate is 100 Hz X Axis = Time Y Axis = Strain

35 Lloyd’s Register Energy - Drilling Expanded plot reveals a signature related to a clicking sound, from the bonnet, heard before rams engaged. More testing and analysis to determine source of signal response. This response appears to respond to the MPLs. Acquisition rate is 1000 Hz Waveforms could confirm bad bearing, MLPs, etc.? Possible to count the threads in the piston rod?

36 Lloyd’s Register Energy - Drilling Ideal System Independent of the OEM equipment Never needs calibration Doesn’t require local power Today subsea engineers rely on: Gallon count Pressure feedback Solenoid diagnostics Tells us strain, temperature, and pressure

37 Lloyd’s Register Energy - Drilling Conclusion/Discussion Sensors were installed in the West Tech facility on a Hydril Pipe Ram. Testing revealed pressure and mechanical elongation of the bonnet. Operational information of the BOP was realized. Software has been developed to replay data acquired during operation to demonstrate operation of the BOP. More testing needed to baseline the BOP. This includes installing more sensors on valves, solenoids, accumulators and hydraulic lines.

38 Lloyd’s Register Energy - Drilling Conclusion/Discussion Future integration of the monitoring systems, with asset management systems currently deployed or in development. These are: LRED BOP RiskWatcher and RiskSpectrum software for real time BOP risk assessment. LRED RIGSIGHT software for asset integrity monitoring and Integrated Operations Management (IOM).
