Ships and marine technology — Design requirements for international ballast water transfer connection flange

This document specifies the material requirements and dimensions of an international flange for the transfer of ballast water between a ship and a shore reception facility, or between ships. It does not address any reconfiguration of the ship's ballast water piping system necessary to connect to the shore-side, e.g. construction of piping from the ship lower machinery levels to the main deck transfer area.

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.

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

Introduction
It is recognized that transfer of ballast water between a ship and a shore-side facility, or another ship,
can be necessary to manage ballast water treatment.
In order for ships and shore facilities to connect the ballast water transfer piping in an efficient
manner, a standardized interface flange is necessary. This type of connection would be similar to the
international fire main ship/shore connection required by the International Convention for the Safety
of Life at Sea (SOLAS).
The need for a standardized international flange for ballast water transfer systems has been presented
to the International Maritime Organization (IMO) Marine Environmental Protection Committee
(MEPC). A standard transfer connection will help enable efficient transfer of ballast water between
ships and facilities in accordance with the Guidel
