MIDSHIP WAVE BENDING MOMENTS IN A MODEL OF THE CARGO SHIP CALIFORNIA BEAR RUNNING AT OBLIQUE HEADINGS IN REGULAR WAVES

Vertical and lateral wave bending moments were measured at the midship section of a 1/96-scale model of the C4-S-1A Mariner-class cargo ship California Bear. The model was self propelled through a ship speed-range of 10 to 22 knots at seven headings to regular waves of lengths between 0.2 and 2.0 times the length between perpendiculars; moderate wave heights not exceeding 1/50 of the model length were used. Results are presented in charts of bending-moment-amplitude/wave-amplitude versus ship speed, with wave length as the parameter. Two ship loading conditions, representative of actual westbound and eastbound trans-Pacific voyages are covered.
