Early in 1979, as part of a study for the National Science Foundation, tests were conducted on the deep ocean working vessel GLOMAR EXPLORER, to determine vessel motion response and stationkeeping characteristics. Wave and motion response spectral densities from these tests are presented along with a comparison of actual significant wave heights and responses compared to those obtained from the spectral densities. A comparison between actual vessel motion response and theoretical motion response as determined by the NSRDC six degree of freedom motion response computer program (HANSEL) and an irregular seas response analysis is also presented. With regards to stationkeeping, measured wind force resolution ("x" and "y" forces) curves are presented, which indicate the magnitude of data spread. Also a table of typical measured data is presented. In addition, a set of smoothed wind and current force coefficients are presented for the vessel modified to a proposed drillship configuration.
