UNIFIED DYNAMIC ANALYSIS OF SHIP RESPONSE TO WAVES

An extensive research program has been aimed at a unified linear dynamic analysis of ship response. The hull is represented as a Timoshenko beam and two forms of strip theory are used to describe the fluid actions. The symmetric response results are illustrated numerically for a fine form hull (a destroyer) and a 250,000 dwt tanker in ballast and fully loaded. The paper is therefore concerned mainly with symmetric response to sinusoidal waves and contains numerous results. The implications for the random case are pointed out in terms of heading, encounter frequency, ratio of ship length to wave length, etc. The effectiveness of contemporary techniques of analysis is discussed. These normally fall into two distinct categories -- those of 'seakeeping' and 'structural analysis' -- by reason of the empirical simplifying assumptions that are conventionally made. This man-made distinction is not strictly tenable and the way these two practical theories fit into this more complete (and, presumably, dependable) dynamical theory is explained.
