Design and Fabrication of Heave Compensation for a Small Off Shore Drilling Rig

Abstract

The Strata Formation on Margins (STRATAFORM) program of the Office of Naval Research seeks to better understand continental margin stratigraphic evolution. In particular, the program is investigating the mode of development of the stratigraphy on the shelf and slope portions of the continental margins using field sites offshore northern California and New Jersey. Investigations of these complex environments involved three-dimensional seismic surveys, long-term (5 yrs) oceanographic and sediment transport monitoring, and near seafloor sediment sampling. The program has developed a comprehensive understanding of present day sediment transport and deposition, but lacks samples (cores) from deeper in the margin to equate the detailed seismic stratigraphy to sedimentation events in the past. The problem has not been the lack desire for these cores, but rather the absence of an affordable means of collecting them.
