The 11th edition of the World Catalog includes many changes in the text that precedes the data listings in each chapter, but very few changes in the way in that data are recorded.

Oil Containment Booms
Booms are listed according to their use in Calm Water, Protected Water, and Open Water.

Oil Spill Skimmers
This chapter describes skimmer types, how they are used, and the general level of performance that can be expected of each type.

This section begins with sorbent definitions and a description of the general types of sorbents that are available. It is followed by a list of criteria to be used in selecting sorbents for various applications and the results of sorbent testing. The results of the most comprehensive tests are presented in some detail.

Oil & Water Separators
This section of the World Catalog contains the results of comprehensive tests of separators suitable for oil spill response.

This chapter discusses pump tests done specifically for oil spill cleanup rating as well as actual spill response experience for pumps that have not been tested in a comprehensive spill cleanup regime.

Beach Cleaners
Spill response for beaches is a complete discipline in itself. Cleaning takes many forms such as Manual. Washing. Mechanical and Vacuum The method used depends on the type of beach and its location, the type of oil, and the equipment and labor available. Key references are reviewed and summarized in this chapter.

Dispersants and Dispersant Application Equipment

Temporary Storage of Recovered Oil
This section reviews the temporary storage alternatives that are available and classifies them according to their use; that is, Calm Water, Protected Water, or Open Water. Further, it suggests skimmer capacities that could be used with each device.

Appendix A: In Situ Burning
The objective of this Appendix is to review the science, technology, operational capabilities and limitations, and ecological consequences of in situ burning as a countermeasure for oil spills on water. The main focus of this section is on marine oil spills in open water conditions.

Appendix B: Estimating Forces on Oil Spill Containment Booms
This Appendix summarizes the work that was performed at Ohmsett, the ITOPF and the Exxon equations and proposes a recommended set of formulae and constants for Calm, Protected, and Open Water classifications.

Appendix C: Oil Spill Encounter Rate for Contingency Planning
This Appendix shows how to compute oil spill encounter rate for advancing skimmers and how this information can be used at spill sites or to develop contingency plans.

Appendix D: Studies on Decanting Recovered Oil Spill Fluids
This Appendix describes a recent, multi-year program of research on decanting of water from recovered oil spill fluids.

Appendix E: Unit Conversions for Oil Spill Response
