NOTE 1 The seabed can be considered as the half-space below the seafloor.

NOTE 2 Offshore foundations are most commonly installed in soils, and the terminology in this part of ISO 19901 reflects this. However, the requirements equally apply to cemented seabed materials and rocks. Thus, the term “soil” does not exclude any other material at or below the seafloor.

NOTE 3 As yet there are no universally accepted definitions of the various types of soil and rock, see A.6.4.3.
