Support for Sea Trials of Active Heave Compensation on the GLAD800 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 stratigraphic development on the shelf and slope portions of the continental margins using field sites offshore northern California and New Jersey. Many of the advances in marine sciences over the past 30 years are based on core samples collected by the Ocean Dripping Program (ODP) and its predecessor the Deep Sea Drilling Program. However, the ODP's principal vessel, the JOIDES Resolution, will not drill in waters shallower than 75 m and has restrictions in waters shallower than 300 m. Recently, DOSECC, Inc., a consortium of universities and other research organizations, designed and fabricated a drilling system (the GLAD800) for the collection of core from modern lakes. This system can support a drill string of 800 m (water + sediment) from an anchored barge.
