PENETRATION OF OBJECTS INTO THE OCEAN BOTTOM (THE STATE OF THE ART)

Abstract

The state of the art of predicting as well as achieving the penetration of objects into the sediments of the ocean floor is presented. Both free-fall as well as driven penetration is reviewed. The information known about ocean bottom soils is briefly summarized. For free-fall penetration the impact velocity, attitude and direction are most important and methods for calculating these parameters are demonstrated. Impact penetration relations are then discussed based on theoretical as well as empirical relations. The theoretical considerations valid for driving objects into the bottom sediments are reviewed and the equipment and machinery available for achieving penetration or for driving piles into the ocean bottom are presented. Recommendations for immediate use and for continuing research are made.
