BS EN ISO 19901-4:2025

This standard BS EN ISO 19901-4:2025 Oil and gas industries including lower carbon energy. Specific requirements for offshore structures is classified in these ICS categories:

• 93.020 Earthworks. Excavations. Foundation construction. Underground works
• 75.180.10 Exploratory, drilling and extraction equipment

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 < 0,5, intermediate foundations, which typically have 0,5 ? L/D ? 10 (see Clause 7), and long and flexible pile foundations with L/D > 10 (see Clauses 8 and 9). This document also provides guidance on soil-structure interaction aspects for flowlines, risers and conductors (see Clause 10) and anchors for floating facilities (see Clause 11). This document contains brief guidance on site and soil characterization, and identification of hazards (see Clause 6). This document can be applied for foundation design for offshore structures used in the lower carbon energy industry.
