Ships and marine technology -- Marine environment protection: performance testing of oil skimmers

This document specifies a methodology for establishing quantitative performance data for oil skimmers for recovery of oil with light and medium viscosity (up to 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 the full-scale test results for the unit tested, under controlled conditions, and for one or more classes of oil. Attention is drawn to the care required when applying the test results to predict skimmer performance under field conditions. For dedicated/in-built systems, the test procedures outlined in this document can only be used for the skimming device as such, not for the entire skimming system.

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).

Any trade name used in this document is information given for the convenience of users and does not

constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

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 21072-2:2009), of which it constitutes a

minor revision. The changes compared to the previous edition are as follows:

— due to the withdrawal of ISO 21072-1, the focus of this second edition of ISO 21072-2 is to address

testing oil skimmers in both low and medium viscosities of oil, in lieu of the procedures provided

in the original ISO 21072-1 and ISO 21072-2, which addressed testing in moving and static water

conditions, respectively. This brings ISO 21072-2 in line with the remaining ISO 21072-3, dealing

with high viscosity oil.

ISO 21072-2:2020(E)
Introduction

ISO 21072 standardizes the 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 results of full-scale tests for a skimmer

under a variety of test conditions, where there is limited or no access to specialist test facilities.
