NAS Peer Review
ERSP Methodology soundUse ASTM 2709-08 for Nameplate RatesConsider different planning scenariosConsider patchiness of thick oilDevelop more detailed user guideConsider all response options

ERSP Strengths
Incentives for better performanceLooks at whole systemFactors in encounter rate issuesEmphasizes rapid responseWell suited for offshore equipment

ERSP Challenges
Assumes best practices for oil spottingGuidance needed on input valuesMobilization & transit to spill not included Maneuverability not factored inNearshore requirements not addressedNot suited for inland environment
