EXPERIMENTAL DATA ON MODEL/SHIP CORRELATION FOR THE MANOEUVRABILITY OF A WIDE-BEAM TANKER

Full-scale manoeuvring tests carried out to evaluate the steering performance of a wide-beam tanker showed that, if a large wide-beam tanker has a rudder large enough to ensure course stability, the performance is similar to that of a conventional ship. To study the scale effect on manoeuvrabilty, results of full-scale manoeuvring trials on a ship of L=350m and B=70m were compared with those from free-running model tests in which three geosim models of 4, 10, and 30 m in length were used. The Authors give an account of these tests, and conclude that:--(i) In the full-load condition, there is only a small scale-effect in the range of large-amplitude motion; in the small-amplitude range, the models are more stable on course and much quicker in response to rudder. (ii) In the ballast condition, there is a substantial difference between the models and the ship. Order from BSRA as No. 49, 781.
