Seafloor Pile Foundations: State-of-the-Art, and Deep-Ocean Emplacement Concepts

D. A. Raecke / H. J. Migliore

A review of the state-of-the-art of the emplacement and design of seafloor pile foundations/anchorages was conducted. Several concepts for emplacement mechanisms suitable for use in water depths to 6,000 feet were considered, and a preliminary effectiveness evaluation of the mechanisms was conducted to reduce the number of systems for further investigation. The state-of-the-art review indicates that marine drilling techniques and equipment could be readily adapted for deep-ocean pile emplacement for a very near-term requirement; however, the use of such a method would be quite costly. Other pile emplacement systems are presently limited to depths of about 1,000 feet by the need for relatively large amounts of power. Development of a 6,000-foot pile foundation/anchorage emplacement capability is not limited by any need to develop novel mechanical equipment. (Author)
