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

4.2.1 Fixed fittings shall be installed on the hull according to the requirements of the layout of fixed
fittings. Fixed fittings with colour marks shall be installed in the corresponding positions with colour
code requirements taken into consideration. Fixed fittings that will require marking after installation
shall be marked. The specific marking requirements are given in Annex C.

in the correct positions with the requirements of their length marks and direction marks taken into
consideration. The specific marking requirements are given in Annex C.
4.2.3 Only securing devices recognized by qualified personnel can be installed and used on-board.
4.2.4 The lashing utility test shall be carried out before the securing device is used for the first time
in a new ship in order to validate the installation and confirm that use of the securing device meet the
requirements of lashing system.
4.2.5 For complex ship types, a lashing simulation test shall be carried out at the beginning of the
lashing design.
4.2.6 For complex lashing, a lashing procedure diagram shall be provided and posted at one, or more,
conspicuous location(s).
4.3 Inspection
4.3.1 Factory inspection
For factory inspection of securing devices, the proof load test shall be carried out on a sampling basis,
see Annexes A and B for loads and test methods.
4.3.2 In-service inspection
Inspections, including initial, annual, intermediate and special inspections, shall be carried out on a
regular basis. Each inspection shall include visual, functional and strength examinations to ensure that
a securing device is in good operational condition.
4.3.2.1 Cycles
4.3.2.1.1 An initial inspection shall be carried out concurrently with the classification survey of the ship.
4.3.2.1.2 An annual inspection shall be carried out concurrently with the annual inspection of the ship.
4.3.2.1.3 An intermediate inspection shall be carried out during daily use.
4.3.2.1.4 A special inspection shall be carried out concurrently with a special inspection of the ship or
after adverse conditions, such as improper operation or experiencing a heavy sea state.
4.3.2.2 Conduct
4.3.2.2.1 Initial inspection
During the initial inspection, the comprehensive inspection shall be carried out for technical
requirements of the securing device, such as materials, process and strength, to ensure that they satisfy
the requirements of drawings approved by classification societies.
Visual inspection shall be carried out before use to ensure that there are no defects.
4.3.2.2.2 Annual inspection
The annual inspection is a general inspection of the securing device, to ensure that it is in effective
operational condition.

ISO 17905:2015(E)

Visual inspection shall be carried out to ensure that galvanized and paint coated surfaces are free of
corrosion, without any breaks, serious wear, deformation, cracks, or severe rust.
4.3.2.2.3 Intermediate inspection
A securing device, whose lashing effect may be loose under stress during use, shall be examined and, if
necessary, immediately adjusted by tightening or relashing.
Inspection shall be carried out after a container is loaded and secured on-board in a low temperature,
or when the ship enters a hot environment.
Visual inspection of a securing device shall be carried out during daily use, to ensure its good performance.
4.3.2.2.4 Special inspection
Comprehensive inspection shall be carried out for all securing devices to ensure galvanized and
paint surfaces are properly anti-corrosive, without any breakage, serious wear, deformation, cracks
or severe rust.
For updated securing devices, the related certificates shall be obtained.
4.4 Maintenance
Maintenance can be subdivided into maintenance of fixed fittings and maintenance of loose fittings.
Securing devices shall be regularly maintained to ensure they are always in good operating condition.
Maintenance is generally conducted immediately after inspection and every six months thereafter.
In case of permanent deformation and damage, securing devices shall be scrapped and any
corresponding parts shall be replaced s
