OPTIMUM T TYPE SHIP DESIGN MEETS FUEL SAVING REQUIREMENTS--SHIP DESIGN PROVIDES FIFTEEN PERCENT FUEL SAVINGS KEEPING THE SAME SPEED

The new ship stern design described in this paper involves application of a large diameter propeller, marks a dramatic change from conventional ship forms, and features a propeller tunnel arranged around the ship's centreline. Major features of the new design are that, as compared with a conventional stern form, it (a) reduces machinery output and permits fuel cost savings; (b) enables deadweight capacity to be increased through requiring smaller machinery space and fuel tank volumes; (c) allows ship hull construction costs to be reduced through offering a simple, low-curvature form. Towing tank tests of the form, including investigations of stern flow behaviour and propulsive performance with a 6-m model, are described. Performance results for a conventional ship and a 74,000-dwt bulk carrier using the new stern form are compared. Order from: BSRA as No. 48,497.
