scope:

This document 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),

⎯ identification of hazards,

⎯ design of pile foundations, and

⎯ soil-structure interaction for risers, flowlines, and auxiliary subsea structures.

Aspects of soil mechanics and foundation engineering that apply equally to offshore and onshore structures are not addressed. The user of this document is expected to be familiar with such aspects.
