Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives ).

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents ).

This document was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee SC 2, Marine environment protection.

This second edition cancels and replaces the first edition (ISO 21072-3:2010), of which it constitutes a minor revision. The changes compared to the previous edition are as follows:

• the focus of this second edition continues to address testing oil skimmers in high viscosity oil, but due to the withdrawal of ISO 20172-1:2019, the following from ISO 20172-1:2019 has been added: the terms and definitions 3.2 through 3.10, and Subclause 4.4, “Oil slick thickness”;
• minor revisions to the key in Figure 1;
• example updated in Table 1.

A list of all parts in the ISO 21072 series can be found on the ISO website.

Introduction

ISO 21072 standardizes performance testing of oil skimmers used in marine pollution control.

Some oil skimmers have previously been performance tested under non-standard conditions and procedures, with declared performance parameters being of limited value to the end user, especially under field conditions.

ISO 21072 provides methods for carrying out and recording the results of full-scale tests for a skimmer under a variety of test conditions.

1 Scope

This document specifies a methodology for establishing quantitative performance data for oil skimmers for recovery of oil with high viscosity (above 50 000 cP), so the end user can objectively judge, compare and evaluate the design and performance of different skimmers. The methodology applies to testing in a basin and requires control of oil properties and oil slick characteristics.

The method is applicable to all types of skimmers provided that the equipment dimensions are within the physical limitations of the test basin. The test procedure provides full-scale test results for the unit tested, under controlled conditions, and for one or more classes of highly viscous oil. Attention is drawn to the care required when applying the test results to predict a realistic skimmer performance under field conditions.

For dedicated/in-built systems, the test procedures outlined in this document are only applicable to the skimming device as such, not to the entire skimming system.
