CRITERIA FOR SHIP SPEED IN ROUGH WEATHER

In this paper, the Authors seek to establish new methods of predicting voluntary speed loss in rough weather. As a result of information received from a number of commanding officers and masters of ships of the Royal Navy and Royal Fleet Auxiliary services the following measures of ship behaviour have been proposed in connection with predictions of voluntary speed loss in rough weather: 1. Slam-induced whipping vibration acceleration at bridge. 2. Subjective motion magnitude weighted according to personnel location and averaged along ship length. 3. Average deck wetness interval at fore-peak. 4. Average propeller emergence interval. Measurements of these data are presented and discussed for the research ship Jordaens and a Dutch destroyer. Methods of calculating the limiting conditions for these two ships are given in a series of Appendices. Order from BSRA as No. 49,678.
