DSRV Alvin weight report : 1972

Abstract

Complete weight and stability computations are presented for the research submarine ALVIN for the year 1972. Longitudinal and vertical components of the BG distance are shown for the vehicle in its normal submerged condition, for the vehicle with the large rock drill attached and then released, and for a number of vehicle emergency conditions. Calculations for pounds per inch immersion and moment to trim one degree also are included. Results of the tethered trim dive are presented and discussed.
