2 Lloyd s Register Energy Conference Safety-driven performance 2012 Agenda Introductions Purpose Questions

3 Lloyd s Register Energy Conference Safety-driven performance 2012 Introduction Introduction to state-of-the-art sensors that can be used in drilling, asset integrity monitoring and meet compliance requirements. 1. Micron Optics Premier supplier of this technology 2. Demonstration of sensor system 3. Presentation on its uses in the GOM and beyond

4 Lloyd s Register Energy Conference Safety-driven performance 2012 Business needs Special projects outlook BOP monitoring Today subsea engineers rely on gallon count, Pressure feedback Solenoid diagnostics

5 Lloyd s Register Energy Conference Safety-driven performance 2012 Ideal system Independent of the OEM equipment Never needs calibration Doesn t require local power Tells us about the strain, temperature, and pressure

6 Lloyd s Register Energy Conference Safety-driven performance 2012 What WEST can show today WEST has an instrumented a BOP on site We are able to detect the pressure inside the BOP bonnet from 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.

7 Lloyd s Register Energy Conference Safety-driven performance 2012 Micron Optics presentation Micron Optics will present some limited number of case studies next WEST with Micron Optics are currently in a riser tensioner monitoring project

9 Lloyd s Register Energy Conference Safety-driven performance Overview Summer ocean clipper drilling riser instrumentation, pilot project, for monitoring of Vortex Induced Vibration (VIV) and fatigue due to ocean currents and vessel heave Summer Mardi Gras transportation system, Thunder Horse field, to monitor VIV and fatigue due to ocean currents, vessel heave and flow assurance February Bass Lite deepwater field GOM to monitor fatigue and flow assurance Future applications in deepwater drilling and production Examples of sensor installations in wind turbine blades Fiber Bragg Gratings briefly explained FBG-based sensors and interrogators Conclusions\discussion

10 Fiber Bragg Gratings Briefly Explained

11 Fiber Bragg Gratings: Operating principle A Fiber Bragg Grating is a special section in the core region of an optical fiber cable in which a periodic series of refractive index changes have been introduced in the fiber. 11

12 Fiber Bragg Gratings: Operating principle

13 Fiber Bragg Gratings: Fiber arrays and Wavelength Division Multiplexing (WDM) addressing Each FBG sensor is at different location on the fiber optic cable, and is allocated a separate central wavelength and an operating wavelength band.
