ÖNORM EN ISO 19901-4

This part of ISO 19901 contains requirements and recommendations 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 characterization, soil and rock characterization, design and installation of foundations supported by the seabed (shallow foundations), and identification of hazards. 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. NOTE 1 Particular requirements for the design of piled foundations, which have a traditional association with fixed steel structures, are given in ISO 19902. NOTE 2 Particular requirements for the design of shallow gravity foundations, which have a traditional association with fixed concrete structures, are detailed in ISO 19903. NOTE 3 Particular requirements for the anchor points of mooring systems of floating structures are detailed in ISO 19901-7 [65]. NOTE 4 Particular requirements for the design of spud can foundations, which have a traditional association with jackup mobile offshore units (MOUs), are detailed in ISO 19905 (all parts).
