Istanbul ferry completes trials

Austal reports that Osman Gazi-1, the first of two Auto Express 88 fast car ferries for the Istanbul Metropolitan Municipality, has completed sea trials prior to the ferry travelling to Istanbul to commence operations.

Designed to operate on a 39 nautical mile service across the Marmara Sea between Yenikapi (Istanbul) and a new port development servicing the city of Bursa, Osman Gazi-1 is scheduled to enter service in April 2007, the same month the second ferry will be launched.

On a demonstration run on Monday for representatives of Turkish municipalities speeds exceeding 43 knots were achieved, impressing the visitors who experienced the ride in the comfort of the luxurious upper deck passenger accommodation.

Earlier, on official sea trials, a higher than contract speed of 37.4 knots was achieved at operating deadweight, 90 percent MCR (power) and with the Ride Control System in operation.

Four MTU 20V8000 M71R engines are installed at a reduced (R) maximum rating of 7,200kW @ 1,150 rpm that allows for low engine stresses, increased fuel efficiency and longer intervals between engine overhauls.

Designed to carry 225 cars, or 158 cars and 128 lane meters for trucks and buses, the car deck has mezzanine levels across all lanes with the center mezzanine capable of being lifted for truck and bus access.

With an open bow above the forward turning area the aft loading point features combined vehicle and passenger ramps for quick deployment and retrieval enabling fast port turnarounds.

Two spacious upper seating levels with 360 degree panoramic window views have the capacity to carry 938 passengers on the lower level and 246 passengers above, where two additional VIP cabins provide lounge seating for 16 for a total of 1,200 passengers.

Passengers on the lower level enjoy Beurteaux Tourist seating in a mixture of standard rows and table settings with two large kiosks providing catering forward and aft. Upper level passengers share a kiosk and are seated in the larger Beurteaux 300 Series Club seats featuring leather trim. Beurteaux VIP Ocean Loungers are provided for the VIP cabins.

Passenger comfort at high speed is aided by Austal's fully active SeaState Ride Control System featuring forward T-foils and transom mounted interceptors providing dynamic pitch and roll stabilization in higher sea states
