Incat 112 m catamaran

Incat lays keel for 112 m cat

Australian shipbuilder Incat has laid the keel for its largest vessel thus far-- a new 112 meter wave piercing catamaran. It is being constructed in a new building hall takes the total undercover facility at Incat to over 50,000 square meters,

The new Wilson's shed was actually partially commissioned in August 2001 when Incat 050 was positioned in the completed drydock, for conversion to HSV-X1 Joint Venture for the U.S. military, but it is not until now that the first keel has been laid in the cavernous building.

"With the laying of the keel of the first of our 112 meter ships, Hull 064, in this building Wilson's is now considered complete," says Incat chairman Robert Clifford. "The jigs, cranes and other equipment required to build large craft, even larger than the 112 m vessel, are being progressively installed in what will be the largest and most modern aluminum shipbuilding facility in the world."

Prefabrication work on the 112 m catamaran has been in progress for some months and the laying of the first section of hull in the new building hall signals the countdown towards vessel completion in late-2006.

The 112 m catamaran complements Incat's highly successful 98 m vessel.

"It had become apparent to Incat and others in the ferry industry that despite the impressive capacity and versatility of the 98 m ship, particularly on the vehicle deck, it was still not large enough for some high volume ferry services, particularly those in Europe," says Robert Cliffor. "As far back as 1998 Incat conceived that a larger vessel was required to fill this market niche for even larger high speed ferries."

At the time, the design brief specified the following criteria:

  • A 40 knot service speed
  • A deadweight capacity of 1000-1500 tonnes
  • Cost minimization in terms of both capital and operating costs
  • The paramount importance of in service reliability
  • The avoidance of "exotic" technology and the minimization of technical risk
  • After two years research the 112 m Wave Piercing Catamaran design, with a waterline length of 106 metres, emerged as a ship capable of meeting or exceeding all design brief goals. Today, six years after commencing its research, Incat is in a position to contract and deliver the 112 metre Wave Piercing Catamaran.

    "As the keel of the first 112 m vessel is laid, it is done against a background of eleven 96/98 m Wave Piercing Catamarans in commercial and military service around the world, making the 96/98 m design one of the most popular high speed ship types in modern times," says Clifford.

    "The Incat 112 m draws on the principles, technology and in service experience of the Incat 98 m yet it is also enhanced to provide significant competitive advantages to operators who need greater capacity, particularly in respect to achieving much higher levels of profitability," he continues.

    The Incat 112 m vessel offers:

  • Dual speed operation (either 23 knots or 40 knots service speed)
  • Up to a 53.9% reduction in fuel costs per deadweight tonne per mile
  • A fuel cost of US $41.58 per nautical mile at 1,000 tonnes deadweight burning MGO
  • A 22-49% increase in transport efficiency
  • 33% increase in the number of available passenger seats
  • 55% increase in the available heavy truck lane metres (can include coaches)
  • 33% increase in normal operating deadweight to 1.000 tonnes
  • 100% increase in available "operational" deadweight to 1,500 tonnes
  • 20% greater operations window plus R0 certification
  • 20% greater station keeping and maneuvering ability
  • 25% reduction in motions and motion sickness index
  • 30% increase in deck area
  • 50% increase in axle loads on vehicle deck
  • Extensive retailing/catering/entertainment opportunities that will boost revenue
  • "The 20 or more years of experience we have amassed allows us to incorporate all the lessons learnt in the most efficient and cost effective manner. There is no doubt this will be reflected in the bottom line of contracted vessels," says Clifford.
