Preliminary Roll and Pitch Predictions for Two Candidate Hull Forms of T-AGS (T, Auxiliary, General Survey)
Abstract
The purpose of this investigation is to make abbreviated ship motion predictions to assist in the preliminary selection of an acceptable hull form for a Military Sealift Command general survey ship identified as T-AGS. General seakeeping characteristics such as deck wetness, bow/stern slamming and associated accelerations are not considered. Only pitch and roll motion predictions are made for two candidate hull forms, one having a conventional hull form and the other a hard chined form. Each of the candidate hulls is expanded into a series of four specific ship geosims. Predictions are presented for one ship speed, three sea states, and four ship headings relative to waves. Comparisons between the two hull forms, on the basis of these predictions, indicate that the hard chined hull rolls and pitches less than the conventional hull form. However, it is not considered possible to infer from these limited results that one hull is a more seaworthy one than the other.
