Title (German)

Erdöl- und Erdgasindustrie - Besondere Anforderungen an Offshore-Bauwerke - Teil 4: Geotechnische und Fundament-Auslegungsmerkmale (ISO 19901-4:2016); Englische Fassung EN ISO 19901-4:2016, nur auf CD-ROM

Overview

This part of ISO 19901 contains provisions for those aspects of geoscience and foundation engineering that are applicable to a broad range of offshore structures, rather than to a particular structure type. Such aspects are: - site and soil characterization; - identification of hazards; - design and installation of shallow foundations supported by the seabed; - design and installation of pile foundations; - soil-structure interaction for auxiliary structures, such as subsea production systems, risers and flowlines (guidance given in A.10); - design of anchors for the stationkeeping systems of floating structures (guidance given in A.11). Particular requirements for marine soil investigations are detailed in ISO 19901-8. Aspects of soil mechanics and foundation engineering that apply equally to offshore and onshore structures are not addressed. The user of this part of ISO 19901 is expected to be familiar with such aspects. For Germany Working Group NA 109-00-01-07 AK "Offshore Bauwerke" ("Offshore structures") at DIN Standards Committee Petroleum and Natural Gas Industries (NÖG) participated in its preparation.
