In the past two years, Wärtsilä NSD has sold medium-speed diesel engines to the value of more than 220 million Euro for ferries, Ro-Ro vessels, cruise ships and other vessels contracted by Greek owners. These involve a total of 103 main diesel engines having an aggregate power of 1.13 million kW. Details of these newbuildings are listed overleaf.
Most of these newbuildings are ferries for upgrading domestic services to the Greek islands and for providing greater capacities on the Adriatic services. In fact, there is something of a ferry revolution in these waters. The major ferry owners and operators have large fleet renewal and expansion programmes, involving much larger and faster vessels than their existing fleets. They are to operate at service speeds of 27 knots and higher, even up to 29.5 knots, requiring particularly powerful machinery installations.
The latest order included in the above statistics is for the engines to be installed in the pair of 30,000 grt ferries contracted by Attica Enterprises at the German shipyard Flender Werft. Due for delivery early in 2002, these ferries will each be powered by four Wärtsilä 12V46C engines of 48,000 kW output for a service speed of 28.5 knots.
This contract continues a relationship between Wärtsilä NSD and Attica Enterprises which began with their first Superfast ferries that entered service in 1995 on the Patras-Ancona route between Greece and Italy. The two ferries contracted at Flender Werft will be the eleventh and twelfth Superfast ferries to be powered by engines from Wärtsilä NSD.
Indeed, it was with the first two Superfast ferries that Attica Enterprises initiated the trend to faster speeds for ferries among Greek owners. With their high service speed of 26.8 knots, these innovative, 23,660 grt ferries built in Germany were each propelled by four Sulzer 12ZA40S medium-speed diesel engines, of 34,560 kW combined output. Attica Enterprises followed up with a second pair of vessels from Kvaerner Masa-Yards Inc in the second quarter of 1998. Slightly large and faster (28.5 knots) than the first pair, the 28,800 grt "Superfast III" and "Superfast IV" are equipped with more powerful propulsion installations, a quartet of Sulzer 16ZA40S engines of 46,080 kW output. Six further ferries were then ordered from Howaldtswerke-Deutsche Werft AG in mid 1998 for delivery from this year onwards, with similar machinery.
