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).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

as well as information about ISO’s adherence to the World Trade Organization (WTO) principles in the
Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.

Ships and marine technology — Marine cranes —
Structural requirements
1 Scope
This document specifies the structural requirements for marine cranes of metal construction.
This document is applicable to the following types of marine cranes:
— deck cranes mounted on ships for handling cargo or containers in harbour or sheltered water
conditions;
— floating cranes or grab cranes mounted on ships, barges or pontoons for operating in harbour
conditions;
— engine room cranes and provision cranes, etc. mounted on ships (including floating docks) for
handling equipment and stores in harbour conditions.
NOTE Marine cranes in other types can refer to this document.
This document is not applicable to the following:
— minimum ambient operating temperatures below −20 °C;
— maximum ambient operating temperatures above +45 °C;
— loads from accidents or collisions;
— lifting operations below sea level;
— transport, assembly, dismantling and decommissioning of cranes;
— lifting accessories, i.e. any item between the crane and the load;
— lifting operations involving more than one crane;
— hand powered cranes;
— emergency rescue operations;
— shore-side cargo handling cranes;
— portable cranes on board;
— lifting appliances for lifeboats, liferafts accommodation ladders and pilot ladders;
— launching appliances for survival craft and rescue boats;
— gangways, accommodation and pilot ladders and their handling appliances.

4 General requirements
4.1 General
4.1.1 The general requirements of the crane structure shall conform to ISO 19354.
4.1.2 Materials, structural types and construction means shall be selected properly in the design of the
crane to meet the strength (including fatigue strength), stability, stiffness and safety requirements of the
structural elements during transportation, installation and use, as well as the requirements of protection
against fire and corrosion.
4.1.3 The composition and arrangement of the crane shall comply with the regulations of applicable
organizations, such as classification societies, and satisfy the operational requirements of the marine
crane to ensure the safety and reliability.
4.1.4 Types of steel and connecting materials shall be noted in the design document; for vital stressed
elements, mechanical properties, chemical composition and other additional guarantee items required
for steel products shall also be noted. Weld forms and quality grades required shall also be noted.
4.2 Materials
4.2.1 The materials shall be applicable to the use and manufacture of the marine crane. The selection
of steel shall take into account such factors as the importance of construction, load characteristics,
stress conditions, connection modes, ambient temperatures for the operation of the crane and steel
thickness. The use of hull steel plates, forgings, and castings as elements shall comply with the applicable
requirements, such as the requirements of classification societies.
4.2.2 The materials shall be manufactured by the approved manufacturer (e.g. approved by
classification societies) with the required material quality certificate. The materials of the main structural
elements shall be of batch member designations. Various tests on materials, such as the performance
test, low-temperature impact test, test on the thickness direction of steel plates, ultrasonic inspection
and surface quality inspection shall also comply with the applicable requirements; the test report and
certificates shall conform to the regulation.
