In 1975/76, design studies and hydraulic model tests were conducted for the construction of an oil terminal at an exposed site in the Bay of Fundy (eastern Canada). The terminal, a joint venture by Eastern Designers (of New Brunswick) and Swan Wooster Engineering (of Vancouver), was to accommodate tankers in the 25,000-dwt to 100,000-dwt range. The studies led to a proposed layout for a berth which included a central loading platform, two berthing dolphins (with pneumatic fenders), and four mooring dolphins (two or the ship's bow and two for the stern). The Authors, of Swan Wooster, discuss this proposed berth layout, together with two variations in which the two outer mooring dolphins were eliminated, thus enabling construction costs to be reduced; the spring lines would be doubled in both these variations. The study and tests indicated that the outer mooring dolphins (and thus the head and stern lines) could be eliminated without adversely affecting the loads in the breast and spring lines. The practicability of such an arrangement was assessed, and it was found that, although the arrangement provides a satisfactory mooring, the design and equipment of many tankers (particularly those under 100,000 dwt) does not lend itself to eliminating the head and stern lines and doubling the springs. The two-mooring-dolphin arrangement for this terminal was therefore not pursued. It is, however, recommended that those concerned should consider the desirability of tankers being suitably equipped for the arrangement.
