Just five years after making its shortsea debut,
Transmanche Ferries has realised the first stage of a fleet renewal programme for the Newhaven/Dieppe route.
Compared with the ships hitherto deployed by Transmanche, the recently commissioned Cote d'Albatre and future consort Seven Sisters signal an advance in ro-pax capacity and speed, achieved through the use of a compact, proven form from Spanish shipbuilder Hijos de J. Barreras.
The investment underscores the Rouen-based company's long-term commitment and bid to strengthen its position on the intensely competitive cross-channel market.
Cote d'Albatre is laid out for 600 passengers, including cabin accommodation totalling nearly 200 berths, and has garaging for a maximum 62 trailers or
for all-up tourist intake of 500 cars. The flexibility conferred by the use of hoistable platform deck sections together with the drive-through configuration allows a range of mixed load permutations, to meet the needs of a year-round route subject to seasonal changes in traffic emphasis.
A typical ro-ro mix, for instance, could be 31 commercial vehicles or
trailers and 224 cars.
The French sisters are based on the 142.45 m x 24.20 m hull form adopted by Barreras for the 2004-built Volcan de Tamasite and Volcan de Timanfaya, delivered to the Armas Group of Spain. The Cote d'Albatreembodies an increased deadweight of some 2,900 tons at the same design draught, a higher power concentration, and the inclusion of a bow visor-type door as well as twin-ramp stern access, with corresponding changes in the internal ramp arrangements relative to the Armas ferries.
Fixed ramps serve inter-deck transfers between the main and upper vehicle
decks, and the moveable car deck and two associated ramps are reached from
the upper level.
By virtue of an 18,900 kW primary power concentration in two Wärtsilä 46-series medium-speed diesels, each of the Transmanche duo will offer a
service speed of 22 knots. This will enable crossing times to be significantly reduced to around three hours, compared with the current four hours.
The main engines drive 4.2 m-diameter Rolls-Royce controllable pitch propellers through a pair of Reintjes reduction gears, each of which is equipped with a power take-off for a 1,875 kVA shaft alternator. The shaft generators serve the at-sea electrical load, and electrical power generation is otherwise the province of three 1,100 kW diesel gensets.
The demands of manoeuvring within the confines of the ports in Normandy and southern England are better met through the provision of a pair of electrically-driven, 1,300 kW bow tunnel thrusters supplied by Rolls-Royce.
The public spaces are located on decks 5 and 6, including cabin accommodation for a total crew and passenger complement of 650. There are 50 passenger cabins, all bar two of which are arranged with four berths, and
the various expressions of attention in the design to overall passenger comfort include the provision of a pair of retractable fin stabilisers.
