A new ferry being prepared by for Trinidad and Tobago in Australia will be using recently launched waterjets designed by Finnish company Wärtsilä.
In a media release dated April 23, 2019, the company said the new Wärtsilä WXJ series of modular waterjets, recently introduced by the technology group Wärtsilä, has been selected for installation in the 100-metre-long catamaran ferry being built for Trinidad and Tobago by Australian company Incat.
The company said the vessel, which is being constructed at the Incat shipyard in Tasmania, Australia, will be powered by four Wärtsilä WXJ1200 waterjets. The order was booked in March 2019.
The company said the new series is a further development and upgrading of the Wärtsilä LJX waterjets.
"Even greater efficiency has been achieved, and the cavitation and underwater noise levels are lower than with the LJX series. The small transom interface dimensions, and the best-in-class weight remain from the earlier series, but the overall performance is improved," the company said.
Lars Anderson, Director Propulsion, Wärtsilä Marine, said Trinidad and Tobago has used Wartsila waterjets in previous vessels and is familiar with the technology.
“We are proud to have been selected again to deliver our Wartsila waterjets for this new high-speed ferry. The well-proven design of Wärtsilä’s waterjets has led to a significant number of repeat orders from world-renowned fast ferry builders, such as Incat."
"Also, the Government of Trinidad & Tobago is already operating multiple catamarans powered by Wärtsilä waterjets, which means that both the yard and the owners are very familiar with the best-in-class quality and performance of our waterjet solutions,” he said.
“We have worked with Wärtsilä for many years already, and we have complete confidence in their waterjets. The new WXJ series takes the performance to an even higher level, bringing even greater value to this exciting new vessel,” said Tim Burnell, CEO, Incat Tasmania.
The company said in addition to the four WXJ waterjets, Wärtsilä will also supply the Wärtsilä ProTouch operational control system.
The equipment is scheduled for delivery in May 2020, and the ferry is expected to be handed over to Trinidad and Tobago in late 2020.
Government has ordered a second vessel from Australian shipbuilding company Austal, also due to be delivered in 2020.
Government said it is pursuing financing arrangements with Australian export credit agency EFIC for these marine vessels.
The company said the ferry will be capable of a service speed of 36 knots and will be able to carry up to 1000 passengers and 239 cars, or a combination of trucks and cars.
Wärtsilä axial waterjets are single stage, compact, high performance systems that combine mixed flow properties with an axial construction. This results in much less space being needed on the vessel’s transom, and greatly increased waterjet cavitation margins for optimum vessel operational flexibility. For naval architects, the axial jet technology creates the possibility to apply a larger power density onto narrower hulls in order to achieve top vessel performance.
