Double-ended ferry BASTØ III


According to the Ferry Technology October 2005

In 2005 the Polish shipyard Remontowa SA delivered a 116m double-ended ferry BASTØ III to the Norwegian owner, Bastø Fosen.

550 passengers are accommodated over one main deck area. The largest lounge can seat 386 passengers in both table and chair and airline-style seating arrangements. It also features facilities including a children play area, dog kennels, toilets, and a bar/food area with the galley located centrally.

The vessel can carry a total of 212 cars: The ferry car decks are arranged on two levels, with ro-ro outfit being supplied by TTS Ships Equipment. Its delivery to the ferry included: key components for the bow visor aft and forward; the aft and forward ramp cover (4.2mx17m); the aft and forward drop gate (1.5mx12m); and the hydraulic and electrical systems.

Although diesel-electric propulsion with rudderpropellers is commonly adopted for this type of ferry, the BASTØ III has a diesel-mechanical/CP propeller propulsion system due to 10% cheaper installation and better fuel economy. Wärtsilä has supplied the complete propulsion package; it comprises two 6-cylinder R32LN engines, each developing 2460kW at 750 rpm and arranged to drive feathering CP propellers via gearing and clutches. Two 3.4m diameter Lips CPS100 propellers are four-bladed, of highly skewed stainless steel designs. Each propeller can be driven by either or both engines, through a crossover shaft connecting the aft engine room with the forward engine room. This arrangement with two separate engine rooms and watertight bulkheads between gearboxes and sterntubes has resulted in the award of DNV’s highest redundancy “RPS” notation: at least 50% of propulsive power can be restored after any single failure in the propulsion chain. The 10m2  flap rudders and rotary vane steering gears were delivered by Rolls-Royce.
