- Abstract
The paper is presented in three parts; Part I, by G. R. McKay, deals with Mourilyan Harbour Model, Part II, by E. C. Fison, deals with Harbour Developmental Works and Part III, by C. R. Tranberg, deals with the Bulk Sugar Terminal.
Part I sets out that there was a considerable body of opinion that the existing form of the Harbour was due in some way to entrance conditions and that any change would destroy the present limited facilities. It describes the construction of the model and the basis of the scale adopted, and concludes that the model showed the true causes of the present conditions and allowed a real estimate to be made of the risk of adverse change resulting from opening the entrance.
Part II gives a short account of the history of Mourilyan Harbour, the deepening of the entrance in the year 1884 from 4ft. 3 in. at Low Water to 12 ft., and in 1912 from 12 ft. to 18 ft., and finally the present day work involving drilling and blasting of the rock entrance to provide a depth of 28 ft. Low Water. The design and construction of a reinforced concrete wharf, 633 ft. x 45 ft., capable of accommodating overseas vessels up to 460 ft. in length, is described with some detail.
Part III briefly refers to the adoption of bulk sugar handling in Queensland and describes the installation at Mourilyan Harbour. Reference is made to the factors leading to the adoption of the particular type and size of storage and features of the structural design; in particular the steel frame and the reinforced concrete retaining walls are discussed. The results of a series of tests to determine the properties of raw sugar and an analysis of these results are tabled. A precis of retaining wall design considerations, particularly under conditions of maximum positive surcharge, is included together with a short statement regarding construction work to date, October, 1959.
