The work of
10、 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
11、, 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
12、/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 possibili
13、ty 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.

22、stoppersMinimum safe working load (SWL) (t)100 000 tonnes DWT or less(Two chain stoppers can also be installed on the ship of such size)1 200Over 100 000 but not greater than 150 000 tonnes DWT(Two chain stoppers can also be installed on the ship of such size)1 250Over 150 000 tonnes DWT 2 350NOTE T
23、he safety factor on yield of bow chain stoppers should be minimum of 2,0 SWL.b) The general types of bow chain stoppers are given in Annex A.c) In the closed position, the design shall be such that it can prevent chafe chains from throw-out due to the sudden release.d) The operating force of bow cha
24、in stoppers shall be not more than 245 N.e) Materials can be weldable cast steel, forged steel, or rolled steel, which conform to the corresponding manufacturing standard.f) The product shall be free from defects that affect its use, such as cracks, sand holes, and pores.g) When the chain stopper is
25、 welded to the foundation, the weld strength shall be capable of withstanding 2,0 times the SWL; when it is bolted to the foundation, effective thrust blocks shall be provided to reduce shear.h) When the ship is provided with the bow chain stopper of an emergency towing arrangement, the SPM bow chai
26、n stopper may also be used as the bow chain stopper of the emergency towing arrangement.2.2.2 Bow fairleadsa) The configuration and load requirements shall be consistent with those of the matching SPM bow chain stoppers.b) The general type of bow fairleads is given in Annex B.c) The bow fairlead sha
27、ll be of closed type, with the opening dimensions of at least 600 mm in width and 450 mm in height.d) The strength should be sufficient for all relevant angles of towline, i.e. up to 90 from the ships centreline to port and starboard and 30 vertical upwards and downwards.e) Materials can be weldable
28、 cast steel, forged steel, or rolled steel, which conform to the corresponding manufacturing standard.f) The product shall be free from defects that affect its use, such as cracks, sand holes, and pores.
