COMPUTER AIDED PREDICTION OF SEAKEEPING PERFORMANCE IN SHIP DESIGN

A computerized procedure is presented for the prediction of seakeeping performance in regular waves and in a seaway. Predictions are made for a given hull form or a Series 60 hull generated by the procedure. The results include: Absolute and relative motions, velocities and accelerations along the hull. Longitudinal shearing forces and bending moments along the hull. Mean added resistance. Seakeeping events, e.g. deck wetness, slamming, etc. Calm water powering. Calm water shearing forces and bending moments. The procedure is documented with all the necessary theoretical information, examples, descriptions of the input data and computer program listings. The program is written in FORTRAN 4 computer language for an IBM/360-65 computer. (Author)
