Title: SEAKEEPING EXPERIMENTS ON THE B.S.R.A. METHODICAL SERIES 0.85 BLOCK COEFFICIENT PARENT FORM
Abstract: Describes experments carried out for BSRA in regular head waves in the St. Albans tank with a model of the BSRA Methodical Series 0.85 block coefficient parent form, and a detailed analysis of the results carried out as part of the hydrodynamics research program of the Vickers Ltd Shipbuilding Group. Motions, propulsion and bending moments at midships were measured and are presented as faired response curves. These are used to predict performance in irregular head waves in a demensionless form so that the performance of geometrically similar ships of any length in waves with any chosen combination of significant waveheight and average period may be derived. The performance of the model is shown to agree closely with the average standards established by Moor and Murdey. The predicted behavior of a ship 800 ft long between perpendiculars is examined in detail and summarized in diagrams relating delivered horsepower, propeller revolutions and speed to significant waveheight, significant bow accelertion and the probability of shipping water over the bow.
