SHIP AND LOCK MODEL STUDIES AS AN AID TO INCREASING CARGO TONNAGE THROUGH THE WELLAND CANAL

The paper describes a program of research carried out by the National Research Council of Canada for the St. Lawrence Seaway Authority into the effect of vessel dimensions and lock modifications on lock transit times in the Welland Canal. Attention was also given to the propulsive effect required by marine shunters or special tugs to maneuver vessels through the locks and channels. This information was required as input to ongoing techno-economic studies being carried out by the Seaway Authority into the most efficient future mode of operation of the Canal--a matter of some importance since its central position in the Seaway system and the concentration of high-lift locks make the Canal a potential limiting factor in the expansion of Seaway trade. The study involved full-scale trials as well as lengthly testing with radio-controlled ship models in a hydraulic lock model. Salient features of the results are reported.
