DANSK DSF/PREN ISO 19901-4 PDF

This document contains provisions for geotechnical engineering design that are applicable to a broad range of offshore structures, rather than to a particular structure type. This document outlines methods developed for the design of shallow foundations with an embedded length (L) to diameter (D) ratio L/D 10 (Clauses 8 and 9). This document also provides guidance on soil-structure interaction aspects for flowlines, risers and conductors (Clause 10) and anchors for floating facilities (Clause 11). This document contains brief guidance on site and soil characterization, and identification of hazards (Clause 6). NOTE – ISO 19901-8 and 19901-10 provide requirements and detailed guidance on these topics. This document does not address aspects of soil mechanics and geotechnical engineering that apply equally to offshore and onshore structures. Figure 1 set outs a high level typical workflow for design of offshore foundations with reference to other relevant ISO standards.
