Standard Guide for Collecting Performance Data on Temporary Storage Devices
SIGNIFICANCE AND USE
4.1 This guide covers the collection of quantitative data in the form of storage capacity, strength of materials, filling and offloading rates, and towability under controlled test conditions. The data can be used for evaluating the design characteristics of a particular temporary storage device or as a means of comparing two or more devices. Caution must be exercised whenever the test data are used to predict performance in actual spill situations since the uncontrolled environmental conditions that affect performance in the field are rarely identical to conditions in the test facility. Other variables such as mechanical reliability, the presence of debris, ease of repair, required operator training, operator fatigue, and transportability also affect performance in an actual spill but are not included in this guide. These variables should be considered along with the test data when making comparisons or evaluations of temporary storage devices.
4.2 Although this guide provides data on the performance of temporary storage devices, all of the combinations of actual conditions of use are not simulated in this series of tests. In particular, the resistance of the device to grounding, abrasion resistance of the container body, venting of the device during loading, and other operational issues not covered by this guide should be considered along with the test data when making comparisons or evaluations of temporary storage devices.
SCOPE
1.1 This guide covers a guideline for measuring the performance parameters of full-scale temporary storage devices that would be used to store oil and oil-water mixtures.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 6.2.

4. Significance and Use
4.1 This guide covers the collection of quantitative data in the form of storage capacity, strength of materials, filling and
offloading rates, and towability under controlled test conditions. The data can be used for evaluating the design characteristics of
a particular temporary storage device or as a means of comparing two or more devices. Caution must be exercised whenever the
test data are used to predict performance in actual spill situations since the uncontrolled environmental conditions that affect
performance in the field are rarely identical to conditions in the test facility. Other variables such as mechanical reliability, the
presence of debris, ease of repair, required operator training, operator fatigue, and transportability also affect performance in an
actual spill but are not included in this guide. These variables should be considered along with the test data when making
comparisons or evaluations of temporary storage devices.
4.2 Although this guide provides data on the performance of temporary storage devices, all of the combinations of actual
conditions of use are not simulated in this series of tests. In particular, the resistance of the device to grounding, abrasion resistance
of the container body, venting of the device during loading, and other operational issues not covered by this guide should be
considered along with the test data when making comparisons or evaluations of temporary storage devices.
F1599 − 95 (2014)
5. Overall Observations
5.1 For each of the tests that follow, the total manpower required to conduct the procedure and the required ancillary equipment
will be noted in the test record. In addition, the total elapsed time for each portion of the tests will be noted.
5.2 Observations of the buoyancy and stability of the deployed device will be made for the marine testing of towable devices.
5.3 Any observations relative to safety will be entered as part of the test record. These should include any hazardous conditions
noted and limitations due to weather conditions, as well as any safety precautions that were observed or should be observed. If
the manufacturer’s specified operating procedures are found to be deficient relative to safety observations, this should be noted.
5.4 The test series should be videotaped to document the tests and procedures.
6. Initial (Static) Loading Tests
6.1 The storage device, and any enclosed ancillary equipment (for example, flotation collars), should be subjected to the
following tests using air or dyed water, as appropriate, in order to confirm the structural integrity and evaluate (qualitatively) any
leakage. The following is presented as a guideline in the absence of manufacturer-supplied guidelines for performing initial loading
tests.
6.2 Overpressure tests can be extremely dangerous, and precautions should be taken against the possibility of sudden and
complete failure of the device. The following tests use large volumes of water or pressurized air, or both, that could cause injury
to personnel and serious damage to property if released suddenly.
6.3 Closed Devices and Enclosed Ancillaries:
6.3.1 Leak Test—The storage device should be inflated with air to a test pressure, calculated as follows:
σ
P 5
15r
where:
P = test pressure (Pa),
σ = minimum ultimate tensile strength of material (N/m), and
r = radius of largest section (m).
6.3.2 Allow the storage device to stand for 30 min at the test pressure 610 %. Maintaining the test pressure within 610 %,
apply a soapy water solution liberally to the seam areas, fitting joints, valves, and all fabric areas. Record and mark air seepage.
NOTE 1—The inspector must determine what is an acceptable leak since some small air leaks may not necessarily mean that a liquid would leak through
the same hole. Also, some air bubbles may be caused by air forced out between the fabric layers and would not cause a liquid leak.
6.3.2.1 Mark and record the location and extent of any surface or seam irregularities, blisters, or cracks. Recheck these areas
carefully for leaks. The inspector must determine the acceptable level of such surface irregularities.
6.3.3 The storage device may be re-tested if leaks can be stopped by tightening the fittings or by minor permanent repairs.
6.3.4 Overpressure—Pressurize the device to 150 % of the rated pressure (defined in 4.2). Hold for 30 min, and then reduce the
pressure to a safe level and inspect for leaks.
6.3.5 If the device exhibits leaks that are not structural failures, rework it and repeat the leak test of 6.3.1. If the device exhibits
leaks that are from structural failure (that is, loose seams, fabric failure, etc.), rework it as necessary and repeat the overpressure
test of 6.3.4.
6.3.6 Closed devices may also be tested using the procedures of 6.4 to determine whether minor air bubble leaks permit water
to leak through the fabric.
6.4 Open Devices:
6.4.1 Leak Test—The following leak test for open devices can be performed only with the device out of water. If the device
cannot be suspended to allow observation of its bottom when full, a sheet of white water sorbent cloth should be placed under it
to indicate leaks.
6.4.2 Fill the device with water to its full operating level. Color the water with a water marker dye that provides a good color
contrast with the storage device and sorbent cloth. Allow the device to stand for 2 h.
6.4.3 Observe and mark obvious leaks. Wipe the seam and leaking areas with a white water sorbent cloth, and determine
whether colored water has leaked through. Mark and record the leaks. No splits or blisters in the coating or seams shall be
acceptable.
6.4.4 The storage device may be re-tested if the leaks can be stopped by tightening the fittings or by minor permanent repairs.
7. Deployment, Loading, and Towing Tests
7.1 General—A visual examination of the device will be conducted once the temporary storage device has been made ready for
deployment. The material specifications and operational limitations of the hose coupling mechanisms and any other fittings, such
as towing bridle, drogue attachments, or securing devices, should be recorded.
F1599 − 95 (2014)
7.2 Towable Devices:
7.2.1 A test of launching from a pier and preparation for deployment by a towing vessel will be conducted by following the
manufacturer’s instructions for break-out, deployment, and preparation for towing. The test will be considered concluded when the
predesignated vessel is able to tow the device away from the dock in a safe and proper configuration.
7.2.2 Towing tests should be conducted under a range of environmental conditions appropriate to the device’s intended use.
(Classification criteria for calm, protected, and open water are given in Practice F625.) Any differences during the test should be
noted as conditions change. The test will be conducted by following the manufacturer’s instructions or, in the absence thereof, by
the opinion of the vessel operator for the most suitable course for the launching, filling, towing, and recovery operation. The test
will be considered concluded when the response vessel has completed all towing tests and recovered and stowed the device in a
safe and proper configuration.
7.2.3 While towing the device, the required towing force will be measured as a function of increasing tow speed. Dynamic loads
should be measured using a recently calibrated load cell. During the towing tests, manufacturer-specified maximum design loads
must be respected with due regard to maximum dynamic load.
7.2.4 Observations should be noted in the test record concerning the device behavior as the towing speed and wave approach
angle are varied. Observations of stability should include vertical stability, twisting, diving, snaking, and yawing. Any distortion
