Freight ferry CONTENTIN


CONTENTIN has been built at the Aker, Helsinki shipyard for UK/France service. The large superstructure at the fore end of the upper deck contains 121 two-berth cabins with en-suite facilities for drivers, together with dining and leisure services. The vessel can accommodate 120 articulated trucks or similar vehicles on three decks, utilising 2200 lane metres. Clear deck heights of 5.2m are offered on the main and upper decks and 4.6m on the tanktop. Vehicle access is over stern and bow door/ramps supplied by MacGregor with internal transfer between decks by means of tiltable ramps.

The single-section main stern ramp/door has a short length of 6.0m (plus 1.5m flaps) and offers a 19.8m-wide driveway into the main vehicle deck. A side-hinged ramp cover accesses the lower hold. This two-section cover is 42m-long and provides a clear opening width of 4.5m to the tanktop. The cover is watertight in the closed position. A hoistable ramp (48m-long plus 5m flaps with a 6.1m driveway) links the main deck and the partly-open upper deck, closing weathertight in the upper deck when not transferring vehicles. Dangerous goods are carried aft of the gas-tight garage door on the weatherdeck.

Forward access into the main vehicle deck is arranged over a three-section bow ramp with an overall length of 17.0m (including 2m flaps) and a driveway of 6.0m. Above, a top-hinged door in the superstructure front allows access at this level to a shoreside linkspan.

The machinery space is located in a “three-quarter aft” position and is fitted out with a power system based on two main engines. With each unit developing a maximum 12MW, the service speed at 85% of this output is 23 knots. Each engine drives a 4.80m Wärtsilä CP propeller turning at 150rpm, through a Flender Navilus reduction gearbox.

Two Leroy Somer 1400kW/1500 rpm alternators, driven from the main engine gearboxes are fitted, along with a pair of Wärtsilä 8L20C/Leroy Somer 1723kVA diesel alternator sets. Two Aalborg 2350kg/h boilers satisfy steam demands, and two Wärtsilä 1200kW bow thrusters are installed. A Frank Monh pump system controls heel and two Blohm + Voss Industries fin stabilisers control roll.
