COMPARATIVE MANOEUVRING TESTS IN MODEL SCALE AND IN FULL SCALE WITH A SINGLE SCREW 220.000 TONS DEADWEIGHT TANKER

The scale effects have always been a problem to the ship designers. The difficulties concerning the assumptions made when predicting the performances of the ship based on model tests have increased with the increasing size of the ships the last few years. This report is meant as a contribution in the efforts to receive more informations about the scale effects concerning the manoeuvreability. The investigations were based on full scale tests carried out on a 220,000 tons deadweight tanker (T/T "Kong Haakon VII") in the summer 1969 and free running tests with its 1:40 scale wooden model in the summer 1971. The extent of the manoeuvring tests performed in full scale appears from Table I. Particulars of the ship (model) and the propeller/rudder configuration are given.
