Ships and marine technology — Tanker cargo manifold shore connection — Technical requirements

This document specifies the types, structure, dimensions and technical requirements of manifolds for oil and chemical tankers. It applies to the cargo and vapour piping systems for the transfer of cargoes of oil or chemical tankers. NOTE This document can be also be applied to the design of bunker (ship fuel) transfer system manifolds for oil or chemical tankers at terminals. ISO 23212 is generally applicable to flanged connections for bunker fuel and lubricating oil transfer to ships from supply vessels or onshore facilities.

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).
