Finnish dynamic positioning system developer Navis Engineering has won a contract from STX Finland Oy to supply its NavDP4000 DP technology to Aura II, currently under construction in Turku, Finland and due for delivery in 2012.
Aura II is a multi-purpose dry cargo ship and Baltic Sea oil recovery vessel that will be deployed by Meriaura Ltd, the Finnish provider of sea transport services for industrial products and general cargo.
It is the first commercial vessel to run entirely on liquid bio-fuels and will be equipped with the Navis DP1 class system, meeting Bureau Veritas DYNAPOS AM/AT class notation requirements.
The NavDP4000 is the latest of Navis’ DP systems, combining elements of its predecessor, Navis IVCS, with latest technology. The system is based on touch-screen operation, designed to allow fast access to all system functions and fewer buttons on the main control panel.
It features a new power management system developed to provide high-speed dynamic positioning reaction to switching-on external power consumers. This protects the user from power blackout failure and reduces power consumption.
One of the other key features of Navis’ DP systems is the Thrust Ability Diagram, which displays all possible combinations of control forces in the surge and sway axes for a given value of the rotational control moment and thruster availability and/or allowed power load.
Navis has delivered more than 350 dynamic positioning systems since launching its first DP system a decade ago.
