EDRC Update John Caplis BSEE Oil Spill Response Division SCAA Annual Meeting

Progress Report EDRC International Oil Spill Conference May 2011 Genwest Study completed Dec 2012 National Academy of Science Peer Review completed Nov 2013

System-based Recovery & Encounter Rate Enhanced Swath Skimmer, Pump & Storage Open Apex Secondary Backup” Storage

Nominal “THICK” Oil Thicknesses After 12 hours (mid-day 1) 2.5 mm After 36 hours (mid-day 2) 1.0mm After 60 hours (mid-day 3) 0.6 mm Oil Encounter Rate Day 1 (bbl/hr)Day 2 (bbl/hr)Day 3 (bbl/hr) System Areal Coverage Rate = ƒ (swath, speed, skimming time ) Estimated Recovery System Potential (For each day’s Operating Window) Day 1 (bbl)Day 2 (bbl)Day 3 (bbl) System Recovery = ƒ (RE, TE, NPRR, Pump Rates, etc)

ERSP System Variables Concentrate & Collect Oil Recover Oil Store Oil (on Skimmer ) Transit & Transfer Oil System Swath & Speed Oil Thickness % Emulsion Nameplate Recovery Rate Recovery Efficiency Throughput Efficiency Onboard Storage % Decant Decant Pump Rate Transit Time Rig/Derig Time Discharge Pump Rate ERSP Calculator

NAS Peer Review ERSP Methodology sound Use ASTM for Nameplate Rates Consider different planning scenarios Consider patchiness of thick oil Develop more detailed user guide Consider all response options

ERSP Strengths Incentives for better performance Looks at whole system Factors in encounter rate issues Emphasizes rapid response Well suited for offshore equipment

ERSP Challenges Assumes best practices for oil spotting Guidance needed on input values Mobilization & transit to spill not included Maneuverability not factored in Nearshore requirements not addressed Not suited for inland environment

ERSP Beta Testing OSRB (Barge) Koseq Arms OSRV 95 ‘ OSRV Shallow Water Barge 46 ‘ OSRV VOSS Unit OSRB (Barge)

ERSP Next Steps Continue beta testing dialogue with industry Address NAS Report Recommendations OSRP Equipment Requirements Study Possible Public Workshop once Study is completed
