HYDRODYNAMIC HULL DESIGN FOR TOTAL ECONOMY IN FINNISH RO-RO

Currently in service between the U.K., Netherlands, and Finland is the 13000 t.d.w. ro-ro/forest products carrier Arcturus, the first of two sisterships built for this run by Rauma Repola for operation by Finanglia Ferries. Both the Arcturus and the sistership Finnmerchant, due for delivery next month, embody a number of interesting features, including a hydrodynamically designed hull form which offers good fuel economy. Extensive model tests were carried out to find optimum solutions for certain special requirements laid down by the owners; these included service opration at two speeds and two draughts. This article describes the factors that have influenced the final design, and gives some information on the model tests including trim optimisation tests. Principal particulars of Arcturus: Length, o.a. 155.00m, b.p. 146.00m; Breadth, extreme 25.00m Depth to main deck 9.40m; Propulsion 2 x Wartsila-Pielstick 12PC2.6V400, 2 x 6600 kW at 520 rpm. Trial speed 10.5 knots at 7.05m draught with two engines at 74% mcr and 15 knots at 8m draught with one engine at 85% mcr.
