Designation:F335018Standard Guide forCollecting Skimmer Performance Data in Ice Conditions1This standard is issued under the fixed designation F3350;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide defines a procedure and measurement criteriato quantify the recovery rate and efficiency of a stationaryskimmer system in drift ice conditions.1.2 The suggested procedure and test parameters are in-tended to provide conditions typical of relatively sparse driftice and relatively dense drift ice coverage.1.3 It is accepted that the recovery rate as determined by thisguide will not likely be achievable under actual conditions ofa spill.The procedure in this guide does not account for suchissues as changing recovery conditions,number of daylighthours,operator downtime,less than ideal control of skimmersettings,and inclement weather.1.4 The procedure in this guide involves the use of specifictest oils that may be considered hazardous materials.It is theresponsibility of the user of this guide to procure and abide bynecessary permits and regulations for the use and disposal oftest oil.1.5 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety,health,and environmental practices and deter-mine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade(TBT)Committee.2.Referenced Documents2.1 ASTM Standards:2D971 Test Method for Interfacial Tension of Oil AgainstWater by the Ring MethodD1298 Test Method for Density,Relative Density,or APIGravity of Crude Petroleum and Liquid Petroleum Prod-ucts by Hydrometer MethodD2983 Test Method for Low-Temperature Viscosity of Au-tomatic Transmission Fluids,Hydraulic Fluids,and Lubri-cants using a Rotational ViscometerD4007 Test Method for Water and Sediment in Crude Oil bythe Centrifuge Method(Laboratory Procedure)F631 Guide for Collecting Skimmer Performance Data inControlled EnvironmentsF2709 Test Method for Determining a Measured NameplateRecovery Rate of Stationary Oil Skimmer Systems3.Terminology3.1 Definitions:3.1.1 oil recovery effciency(ORE),nthe ratio,expressedas a percentage,of the volume of oil recovered to the totalvolume of fluid recovered.3.1.2 oil recovery rate(ORR),nthe volume of oil recov-ered by the device per unit of time(m3/h).3.1.2.1 DiscussionNote that the measurement is of oilonly,after netting out free and emulsified water.3.1.3 operational effciency(OpEff),nthe ratio,expressedas a percentage,of the time spent actually skimming to the totaltest time,having deducted time spent out of the water tore-position the device.3.1.3.1 DiscussionThis may be of particular interest indense ice cover,when a significant portion of the test periodmay be spent re-positioning the skimmer to find thick patchesof oil.3.1.4 skimmer system,na skimmer along with its associ-ated power supply,hydraulic lines,offloading pump,controlapparatus,and accessories.3.1.5 total test time,nthe period of time from the start toend of collecting recovered fluids for measurement includingrepositioning.4.Significance and Use4.1 This guide establishes test conditions that will provide ameasured oil recovery rate and efficiency for a skimmeroperating in drift ice.1This guide is under the jurisdiction of ASTM Committee F20 on HazardousSubstances and Oil Spill Response and is the direct responsibility of SubcommitteeF20.12 on Removal.Current edition approved Nov.1,2018.Published February 2019.DOI:10.1520/F3350-18.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United StatesThis international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for theDevelopment of International Standards,Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade(TBT)Committee.1 4.2 End users need a procedure to quantify optimum per-formance data for planning and selection of equipment.4.3 The procedure in this guide will assist in verifying andaccurately reporting skimmer system performance.4.4 Tests will be conducted under well document
