Weight, buoyancy and stabiltiy of DSRV Alvin, 1967

Abstract

A complete weight and stability analysis for the research submarine ALVIN is presented. Weights, displacements, locations of center of gravity and center of buoyancy, and longitudinal and vertical components of the BG distance are given for the submarine in its normal condition, and in a number of emergency conditions. A computer program was set up for this purpose and results were obtained using the WHOI computer. The metacentric height GM was calculated using a semi-graphical method. Some of the results obtained in the ALVIN dockside trials are included. Experimentally determined values of BG and GM are compared with the computed values.
