Description
The critical speed of a high speed container ship in irregular waves is investigated theoretically by strip method and statistical calculations. In this paper, “deliberate loss of speed” is mainly discussed in details.<BR>The purpose of this study is the followings : <BR>(1) To find the best way of shiphandling in rough sea.<BR>(2) To inquire into the ship forms which have better seakeeping qualities.<BR>Seven factors of seaworthiness are discussed : <BR>(1) Vertical Acceleration at F. P.<BR>(2) Deck Wetness at F. P.<BR>(3) Slamming<BR>(4) Vertical Wave Bending Moment<BR>(5) Propeller Racing<BR>(6) Lateral Acceleration at S. S. 81/2<BR>(7) Rolling<BR>The critical values and probabilities of these factors are checked, and the maximum ship speed, . below which a ship safely navigates across the rough sea, is determined.<BR>These analyses are possible for all kinds of ships, and they will be usefull not only for ship-handlers but also for ship designers who are concerned about seakeeping qualities of ships.
