6 FORECAST SITES

7 WHAT IS A WEATHER FORECAST? A prediction of the future state of the atmosphere based on current atmospheric conditions

8 OBSERVATIONS Key to accurate forecasts Provide an accurate starting point to the forecast Allow real-time monitoring Provide a dataset for analyses, e.g. - forecast verification - hindcast reports - future design criteria

9 FORECASTING Forecast Models simulate the physical processes of the atmosphere to produce a numerical forecast

10 FINE SCALE MODELLING External Data From Global to Local 3DVar/ENKF SAM Global Models km Regional Models 1-16 km Local Fine Scale Models 300m-4 km WRF 9 km WRF 3 km WRF 1 km SWAN 300m Projects

11 THE NEARSHORE ENVIRONMENT Challenges: Model Land/Sea mask Coastal Effects Tidal Effects Successful Forecasts: Observations Forecaster Intervention May Require Fine-scale Models Grid spacing 16km

13 WAVE MODELS AT 300M RESOLUTION SWAN 300 m Broadhaven Hit 72% ME -0.2 ECMWF ECMWF Hit 65% ME -0.3

14 WAVE MODELS AT 300M RESOLUTION SWAN 300 m Broadhaven Hit 72% ME -0.2 June 2013 Broadhaven Bay Swan model identified an operational window for a Shell umbilical laying job that saved 2-3 weeks of work ECMWF ECMWF Hit 65% ME -0.3

15 THE FORECAST PROCESS Numerical Modelling Observations Customer Forecast Human Forecaster

16 THE FORECAST PROCESS Forecaster intervention is done on raw model output

18 THE FORECAST PROCESS Forecasts to Customer

19 THE FORECAST PROCESS Forecasts to Customer

20 THE FORECAST PROCESS Forecasts to Customer

21 THE FORECAST PROCESS Forecasts to Customer Hi Bard1 High risk of lightning between 1500 and 1800 today when front passes

22 THE FORECAST PROCESS Forecasts to Customer OK RWE NSO High confidence of weather window tomorrow. Hsig falling below 2.1m between 0300 and 2200

23 THE FORECAST PROCESS Forecasts to Customer Yes LAL Winds above 22ms-1 for next 12 hours, but decreasing below by 0600 tomorrow

24 SAFE AND EFFICIENT OPERATIONS We manage numerous customer operational limits. It can be very complex! One Customer typically has the following limits: Crew boat transfer to turbines: Hsig = m Crew transfer to turbines by helicopter: Wind 22 m/s. Vis. 5km. Cloud base 1500ft Work on rotating parts in turbine: 15 m/s All work on turbine: 25 m/s

25 SAFE AND EFFICIENT OPERATIONS We manage numerous customer operational limits. It can be very complex! and more: Crane vessel ops: Transfer: Hs 2m. Wave period 8s Jack-up: Hs m - depending on direction of vessel vs wave direction Crane ops: 9m/s at 100m

26 CERTIFIED AVIATION FORECASTS Position StormGeo is the challenger in this market, as well as offering services to oil&gas operators not having integrated solutions today. Products Official aviation forecasts Operational decision guidance Aviation training Aviation instrumentation Certification StormGeo is the only ICAO certified private company in Europe for producing aviation forecasts.

27 DECISION SUPPORT SOLUTIONS Integration of our capabilities and deliveries into our customers operative environment We help our customers to Manage risk Improve planning Control cost Reduce down-time Protect revenue
