Abstract:

The NAVY Standard Ship Motion Program SMP received a major revision in 1995 and later. The program code was upgraded to improve maintainability, portability and efficiency. Generality was improved by increasing the number of hull stations and points per station and the determination of wave frequency ranges. The roll damping predictions, active fins and rudders controller, added resistance predictions, and hull bending and shear loads calculations were substantially improved. Seaway definition options were extended to include wave spectra for restricted waters. Absolute motions at a point can now be expressed in terms of motion sickness incidence and motion induced interruptions. Relative motions at a point may now include sinkage, trim and wave profile effects, with slamming expressed in terms of local pressure or force. Passive roll tank stabilizers can now be modeled. The general input and output description is provided. Program operation is described. The detailed preparation of the program input record sets is presented.
