Ships and marine technology — Marine environment protection: performance testing of oil skimmers — Part 3: High viscosity oil
ISO 21072-3:2010 specifies a methodology for establishing quantitative performance data for oil skimmers for recovery of oil with high viscosity, 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 skimmer 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/inbuilt systems the test procedures outlined in this part of ISO 21072 are only applicable to the skimming device as such, not 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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 21072-3 was prepared by Technical Committee ISO/TC 8, Ships and marine technology, Subcommittee
SC 2, Marine environment protection.
ISO 21072 consists of the following parts, under the general title Ships and marine technology — Marine
environment protection: performance testing of oil skimmers:
⎯ Part 1: Moving water conditions
⎯ Part 2: Static water conditions
⎯ Part 3: High viscosity oil

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

High viscosity oil
1 Scope
This part of ISO 21072 specifies a methodology for establishing quantitative performance data for oil
skimmers for recovery of oil with high viscosity, 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 skimmer 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/inbuilt systems the test procedures outlined in this part of ISO 21072 are only applicable to the
skimming device as such, not the entire skimming system.
