The paper discusses in situ cone penetration and laboratory testing of calcareous soils at several offshore locations. These tests indicate a large range in degree of cementation. The laboratory program includes special strength and deformation tests to further clarify and interpret the results of cone penetration tests. In addition, these tests are designed to provide a better understanding of the behavior of pile foundations. Based on the preceding results a classification system is proposed for these types of soil with emphasis on in situ measurements. Furthermore, engineering design parameters are discussed and values suggested for skin friction and end bearing for pile foundations.
