These other structures can have a great range of variability in geometry and structural forms (e.g. tension leg platforms) and, therefore, can be only partly covered by the requirements of this document. In other cases, specific requirements stated in this document can be found not to apply to all or part of a structure under consideration.<\/p>\n<div class=\"non-normative-note\">\n<div class=\"note-label\">\n   NOTE&nbsp;4\n  <\/div>\n<p>Requirements for topsides structures are presented in <span class=\"std\"> <span class=\"std-ref\">ISO&nbsp;19901-3<\/span> <\/span>.<\/p>\n<\/p><\/div>\n<p>In the above cases, conformity with this document requires the design to be based upon its underpinning principles and to achieve a level of safety equivalent, or superior, to the level implicit in it.<\/p>\n<div class=\"non-normative-note\">\n<div class=\"note-label\">\n   NOTE&nbsp;5\n  <\/div>\n<p>The speed of evolution of offshore technology often far exceeds the pace at which the industry achieves substantial agreement on innovation in structural concepts, structural shapes or forms, structural components and associated analysis and design practices, which are continuously refined and enhanced. On the other hand, International Standards can only capture explicit industry consensus, which requires maturation and acceptance of new ideas. Consequently, advanced structural concepts can, in some cases, only be partly covered by the requirements of this document.<\/p>\n<\/p><\/div>\n<p>This document is applicable to steel floating structures. The principles documented herein are, however, considered to be generally applicable to structures fabricated in materials other than steel.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\"
