Feature 4 | RO-RO FERRY REPORT Nordic contract calls for capacity boost
Ship conversions and the prospect of a new aluminium fast catamaran for Nordic Ferry Services.
N
ordic Ferry Services A/S has emerged victorious after Danish Ministry of Transport put out ferry
services between the island of Bornholm and the Danish mainland to tender, covering the period September 2011 to September 2017. In securing the tender, the shipowner has
ordered a new fast ferry from Austal, and increasing the capacity of two existing ships. The routes involved are currently operated
by Bornholmstrafikken A/S but, to meet future demands, the company joined forces with Clipper Group to form Nordic Ferry Services, headquartered in Bornholm. In its tender, the Ministry of Transport made
plain that it required the successful bidder to increase service capacity substantially. The route between port of Roenne
(Bornholm) and Ystad (Sweden) is now served by the high speed craft Villum Clausen, which offers capacity for 1038 passengers and 200 cars), and a ro-pax ferry offering capacity for 400 passengers and 1200 lane metres. To meet the new requirement, a larger newbuild

fast ferry is needed, with capacity for 1400 passengers and 357 cars, or 300 lane metres as truck/trailer capacity, plus 269 cars. The requirement from the Ministry is that the service will be able to transport 10.000 passengers, 2200 cars and 300 lane metres of cargo per day during the high season, in both directions. To meet this target, Nordic Ferry Services
has ordered an aluminum 112.6m long catamaran from Austal, for delivery as soon as May 2011. The ship will be able to operate at 37.6knots at 90% MCR. Classed in line with the IMO’s High Speed Craft Code 2000, the ship would be capable of operating in wave heights up to 4.5m, and would feature bulbous bows, a symmetric hull and a round bilge. Meanwhile, the overnight route between
the port of Roenne (Bornholm) and Koege (Seeland) is currently served by two ro-pax vessels, offering capacity of 1200 lane metres and 400 passengers. The new requirement from the Ministry on this route is that, from 2011, services must be able to accommodate 1500 lane metres plus 400 passengers each way every day. To meet this requirement, it will be necessary to upgrade the in-service, 124.9m long ro-pax vessel Hammerode, built in 2005 at Merwede, and to ensure that it achieves one round trip a day. The required
space will be created by adding a further ro-ro deck aft of the funnel. Some existing cabins will also be converted into seating areas. Conversion will take place in 2010. Mr Hansen said that Hammerode’s
manouevrability would need to be improved as part of the project. He said that the conversion would therefore also entail the beefing up of power for her bow thrusters. He added that it was also imperative that service speed was maintained at the current 18.5knots. “This is to be solved by underwater hydrodynamic improvements,” said Mr Hansen, “for example, by adding a new ducktail and interceptor, and new bulbous rudders in a new position, in line with the propeller shafts.” The ducktail will also play its part in
addressing demand for about 10% more displacement, Mr Hansen said, where ship’s draught will also be increased, and a set of sponsons added. A second ro-pax vessel, Dueodde, will be
upgraded, in order to offer capacity for 770 passengers, against her current capacity of 400 passengers, through converting part of its cabin space to open seating areas. She will be redelivered into service between the island of Bornholm and the German port of Sassnitz after conversion, expected in late 2011 or early 2012. NA
