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.

Introduction

Marine environment protection is required by national, regional and international regulations.

The International Convention for the Prevention of Pollution by Ships (MARPOL) was adopted in 1973 and it has been regularly updated by amendments made by the Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO). MARPOL is the legal basis for the prevention of marine pollution. MARPOL requires the installation of oil-water separation systems to treat fluids consisting of mixtures of oil and water generated on board ships.

On fixed offshore marine structures (e.g. converter stations and transformer substations of offshore wind turbines), oil-in-water emulsions, oily mixtures of surface water, fuel and lubrication oil, and many other substances covered by regulations might spill or otherwise cause hazards. Hence there is a need to separate these mixtures to an oil concentration of less than what is currently required by MARPOL.

1 Scope

This document provides requirements and test methods for tanks, piping and separation systems facilitating the separation of contaminated fluids of oil and water on fixed offshore marine structures and ships, where treatment is performed by separation systems that optimize oil-water separation to a concentration equal to or less than 5 ppm.

It is applicable to fixed offshore marine structures and to ships operating in designated sea areas determined by the relevant authorities.
