Lienchiang County Government of Taiwan has ordered two 9L32/44CR four-stroke engines to power a Ropax vessel sailing between Keelung and the Matsu islands, an archipelago located close to the Chinese mainland. The medium-speed engines will form part of a complete propulsion system delivered by MAN Diesel & Turbo that also includes reversible gearboxes, MAN Alpha twin-screw fixed-pitch propellers and a ship alarm system.
The 106-metre ferry will be built by Jade Shipbuilding, Kaohsiung, SW Taiwan and will travel six days a week between Keelung and the Matsu islands. MAN Diesel & Turbo will build the engines at its facility in Augsburg, Germany. Delivery of the propulsion system is scheduled for December 2012 with vessel delivery timed for January 2014.
As a customer, Lienchiang County had a number of key requirements for the propulsion system, including:
Ultimately, these requirements favoured the adoption of MAN Diesel & Turbo’s Common Rail technology versus that of conventional injection technology. The fixed-pitch propeller transmits a power of 4,635 kW per engine and, as the highest propeller efficiency possible – balanced with low noise and vibration – were key factors, the MAN Alpha fixed-pitch propellers were a natural choice. A water-lubricated stern tube arrangement was also selected to obtain the most environmentally friendly shafting solution.
For safety on board, MAN Diesel & Turbo also employed a ship alarm system that displays messages in traditional Chinese characters.
