The paper describes methods for evaluating and comparing motion characteristics, structural integrity, and stability of semisubmersible drilling vessels. A computer program for predicting semisubmersible motions is presented, along with evidence of its validity. The range of heave values calculated for nine different rig designs is shown for both regular and irregular waves. A method for analyzing stresses in irregular seas and a computer program for evaluating semisubmersible stability is described. (Authors)
