16、f test methods to determinethe oil containment effectiveness of containment booms whenthey are subjected to a variety of towing and wave conditions.The test methods measure the tow speed at which the boomfirst loses oil (both in calm water and in various waveconditions), the tow speed at which the b

19、 discussion).4.3 Other variables such as ease of repair and deployment,required operator training, operator fatigue, and transportabil-ity also affect performance in an actual spill but are notmeasured in this guide. These variables should be consideredalong with the test data when making comparison

20、s or evalua-tions of containment booms.5. Summary of Guide5.1 This guide provides standardized procedures for evalu-ating any boom system and provides an evaluation of aparticular booms attributes in different environmental condi-tions and the ability to compare test results of a particular boomtype

21、 with others having undergone these standard tests.5.2 The maximum wave and tow speeds at which any boomcan effectively gather and contain oil are known as boundaryconditions. Booms that cannot maintain their design draft,freeboard, profile, and buoyancy at these conditions may beless effective. The

22、 boundary conditions depend on the charac-teristics of oil viscosity, oil/water interfacial tension andoil/water density gradient.6. Test Facilities6.1 Several types of test facilities can be used to conduct thetests outlined in this guide:6.1.1 Wave/Tow TankA wave/tow tank has a movablebridge or ot

23、her mechanism for towing the test device throughwater for the length of the facility. A wave generator may beinstalled on one end, or on the side of the facility, or both.6.1.2 Current TankA current tank is a water-filled tankequipped with a pump or other propulsion system for movingthe water throug

24、h a test section where the test device ismounted.Awave generator may be installed on this type of testfacility.6.1.3 Other facilities, such as private ponds or flumes, mayalso be used, provided the test parameters can be suitablycontrolled.6.2 Ancillary systems for facilities include, but are notlim

25、ited to a distribution system for accurately delivering testfluids to the water surface, skimming systems to assist incleaning the facility between tests, and adequate tankage forstoring the test fluids.7. Test Configuration and Instrumentation7.1 The boom should be rigged in a catenary configuratio

26、n,with the gap equal to 33 % of the length; or boom gap-to-length ratio of 1:3. Towing bridles are generally supplied by themanufacturer for both ends of the boom which provideattachment points for towing (Fig. 1).At each end of the boom,the towing apparatus shall be joined to the tow bridle or towl

27、ead by a single point only. Boom towing force should bemeasured with in-line load cells positioned between the boomtowing bridles and tow points.7.2 Preload oil should be pumped directly into the boomapex.7.3 Data obtained during each test should include electroni-cally collected data and manually c

28、ollected data. Oil and waterFIG. 1 Typical Boom Test Setup in TankF2084/F2084M 01 (2012)12property data should be based on fluid samples obtained duringthe test period. Recommended data to be collected duringtesting, along with the method of collection, is listed in Table1.8. Test Fluids8.1 Test flu

29、ids may be crude, refined, or simulated, butshould be stable and have properties that do not vary during atest run. Test oils for use with this guide should be selected tofall within the range of typical oil properties as defined inAppendix X2 of this guide.8.2 Test fluids should be discharged at am

30、bient watertemperatures to reduce variation in fluid properties through atest run.9. Safety Precautions9.1 Test operation shall conform to established safety (andregulatory) requirements for both test facility operations andoil handling. Particular caution must be exercised when han-dling flammable

31、or toxic test fluids.10. Test Variables10.1 At the onset of the test the independent or controlledtest parameters should be selected. The test evaluator shouldinclude a discussion of the procedures that were used toestablish calibration and standardization. These procedurestypically include initial

32、calibrations, pre-test and post-testchecks, sampling requirements and documentation of signifi-cant occurrences/variations, and data precision and accuracy.10.2 Data should be expressed with an indication of vari-ability. Table 2 contains a list of typical measurements showingattainable precision an

33、d accuracy values.10.3 Varying surface conditions should be employed duringtesting. Conditions should be measurable and repeatable.Examples of achievable surface conditions in controlled testenvironments are:10.3.1 CalmNo waves generated.10.3.2 Wave #1sinusoidal wave with an H13 of .30 metres12.0 in

34、ches, wavelength of 4.27 metres 14.0 feet, and anaverage period of t=1.7 seconds. (Wave dampening beaches areemployed during the generation of this wave condition).10.3.3 Wave #2Sinusoidal wave with an H13 of .42 metres16.5 inches, wavelength of 12.8 metres 42.0 feet, and anaverage period of t=2.9 s

35、econds. (Wave dampening beaches areemployed during the generation of this wave condition).10.3.4 Wave #3A harbor chop condition with an averageH13 of .38 metres 15.0 inches. This is also defined as aconfused sea condition where reflective waves are allowed todevelop. No wavelength is calculated for

36、this condition.where:H13 = significant wave height = the average of the highest13of measured waves,L = wavelength = the distance on a sine wave from troughto trough (or peak to peak), andT = wave period = the time it takes to travel one wave-length.11.

Document set-up conditions, for example, towbridle elevation, boom gap opening, and/or general rigging.Start the oil distribution system, tow mechanism or water flow(if necessary) to begin the test run.

48、multaneously determine the volume of test fluid aboom holds until the addition of fluid has a “minimal” effect onthe first loss tow speed. As preload volumes are increased,there is a volume at which the addition of test fluid will notchange the first loss tow speed (test fluid/water interfaceentrain

49、ment speed). This test is performed in calm waterconditions and establishes a baseline preload fluid volume.This baseline containment performance serves as a datum fromwhich improved or diminished containment performance canbe measured when encountering other test conditions.11.3.2.1 The preload volume is determined by performing aseries of first loss tests. Beginning with a nominal preloadvolume, the first loss tow speed is identified. Underwatervisibility is essential when identifying loss speeds. The preloadvolume is increased a
