The work of preparing International Standards is normally carried
4、out through ISO technical committees. Esch 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. Dr
5、aft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the ISO Council. They are approved in accordance with ISO procedures requiring at least 75 % approval by the member bodies voting. In
6、ternational Standard ISO 6645 was prepared by Technical Committee ISO/TC 8, Shipbuifding and marine structures. Users should note that all International Standards undergo revision from time to time and that any reference made herein to any other International Standard implies its latest edition, unl

15、 numerical value without unit for reference and ordering pur- poses; it is derived from the maximum load exerted by the lead block and calculated by the derrick assembly diagram of forces, in kilonewtons. 5 Derrick gooseneck bearing assemblies 5.1 Types The assemblies are divided into three types as
