Standard Guide for Oil Spill Dispersant Application Equipment: Single-point Spray Systems

ABSTRACT
This guide covers performance criteria, requirements, material characteristics, and essential features for oil spill dispersant application systems. This guide also covers vessel-based spray systems employing single-point spray nozzles. Oil spill dispersant spray equipment shall conform to the minimum performance requirements such as target dosage, dispersant flow or injection rate determination, droplet size distribution, and maximum delivery variation over spray switch. Materials used in the spray systems shall be corrosion-resistant to salt water and shall be able to be used or stored at extreme temperatures. Performance data shall be provided to user, including information such as dilute versus neat application, dosage chart, accuracy of data, nozzles and pumps, and operational manual.
SCOPE
1.1 This guide covers performance 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 vessel-based spray systems employing single-point spray nozzles, including designs that have been based on or evolved from “fire-monitor” systems, and is not fully applicable to other systems such as spray boom/nozzle or aircraft systems.  
1.3 This guide is one of five related to dispersant application systems. The other four guides cover the design of boom and nozzle systems, spray system calibration, spray deposition measurements, and use of the systems. Familiarity with all five guides (listed in 2.1) is recommended.  
1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
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.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.

3. Equipment Description
3.1 General—“Single-point” oil spill dispersant spray systems include spray nozzles, some of which may be similar to those
used in firefighting, that generate a spray pattern directed out from a location on the side of the vessel without the need for an
outrigger boom or spray arm system to support the spray nozzle. The system includes a pumping or pressure system to deliver
dispersants to the nozzle(s) or device used to spray the dispersant out onto the oil slick, and associated piping and control valves.
All systems shall include flow meters and pressure gauges to monitor the dispersant discharge. All systems shall be equipped with
provision for cleaning and drainage. System components shall be designed to give a uniform droplet spray and volumetric coverage
as described in this guide.
NOTE 1—Nozzles used in firefighting applications are generally designed to direct a large quantity of water or firefighting foam, or both, to a small
area or fire hot spot. As such, many standard firefighting nozzles are not suitable for effective application of dispersant. Some firefighting nozzles have
variable spray pattern adjustment and flow control and these may be suitable for dispersant application. Some foam application nozzles have been
designed to generate uniform, volumetric fallout along the length of their spray pattern and these have potential for dispersant application. Nozzles
