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).

Ships and marine technology — Marine cranes — Design
requirements for low temperature operation
1 Scope
This document specifies the requirements for design, construction, safety, performance, acceptance
test and operation of marine cranes for low temperature operation.
This document is applicable to marine cranes of the following types, which are exposed to and operated
in low temperatures:
— deck cranes mounted on ships for handling cargo or containers in harbour or sheltered water
conditions;
— floating cranes or grab cranes mounted on barges or pontoons for operating in harbour conditions
or sheltered water conditions;
— engine room cranes and provision cranes, etc. mounted on ships (including floating docks) for
handling equipment and stores in harbour conditions.
This document is not applicable to the following:
— minimum ambient operating temperatures no less than −20 °C;
— maximum ambient operating temperatures above +45 °C;
— 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.
