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).

Introduction
Shafting lines are available on the vast majority of self-propelled inland navigation vessels. They
mechanically connect the engine and the propulsion unit of the vessel. Shafting lines transfer power
and moment between the elements of the power plant and the propulsion complex of the vessel in the
direction from the engine to the propulsion unit. Shafting is one of the most important devices on a
ship, critical to the safe operation of the ship.
Inland navigation vessels are outside the competence of the IMO. Therefore, ISO standards are an
effective way to implement best practices for inland waterways and inland navigation vessels.
The standardization of the terms related to the shafting of inland navigation vessels provides an
unambiguous understanding of information materials on this topic. This is especially important for
international cooperation in anticipation of the introduction of smart (machine-understandable)
standards, including those applicable to ships and marine technologies.

1 S cope
This document specifies terms and definitions relating to inland navigation vessels shaftings, with the
aim of providing clear definitions which can be understood by all specialists.
This document is applicable only to equipment which is used for the vessels being used for the inland
navigation.
The terms specified in this document are intended to be used in documentation of all kinds. Certain
standardized terms are also given with their abridged version; these can be used in cases where no
possibility of misinterpretation can arise.
A combination of terms is allowed in application.
