Standard Guide for Oil Spill Dispersant Application Equipment: Boom and Nozzle Systems
ABSTRACT
This guide covers design criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems, it covers spray systems employing booms and nozzles for use on boats or ships and helicopters or airplane. The equipment description, equipment minimum performance specification, and equipment design are presented in details. Materials on ship or boat systems should be corrosion-resistant to salt water. All materials that come into contact with dispersants should be compatible with that dispersant.
SCOPE
1.1 This guide covers design criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems. This guide is not intended to be restrictive to a specific configuration.
1.2 This guide covers spray systems employing booms and nozzles and is not fully applicable to other systems such as fire monitors, sonic distributors, or fan-spray guns.
1.3 This guide covers systems for use on ships, boats, helicopters, or airplanes.
1.4 This guide is one of several related to dispersant application systems using booms and nozzles. One is on design, one on calibration, one on deposition measurements, and one on the use of the systems. Familiarity with all four guides is recommended.
1.5 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
