THEORETICAL ESTIMATES OF WAVE LOADS ON THE SL-7 CONTAINER SHIP IN REGULAR AND IRREGULAR SEAS (SL-7-4)
The computer program SCORES for predicting ship structural response in waves is applied to the SL-7 container ship. The operating conditions considered are 2 displacements, 4 ship speeds, 21 wavelengths, 19 headings and 5 sea states assuming both long-crested and short-crested seas. These results constitute a complete data bank for the SL-7 ship in the form of both frequency responses for regular waves as well as rms and other statistical response measures for irregular seas. Comparison is made between the computer and model tests of the SL-7 in regular waves in predicting vertical, lateral and torsional moments, and vertical and lateral shears at two sections and heave, pitch and roll. Regions where the theory and model experiment do not agree have been pointed out and some means of correction or extension of the theory is discussed.
