{mprestriction ids="1,2"}The fourth generation DEGO software collates data from sensors monitoring 60 shipboard parameters in real time, including engine performance, propeller performance, rudder/vessel centre of gravity torque and navigational information.

In an improvement on earlier incarnations of the application, DEGO version IV can now use that data to model a control strategy to minimise ship roll, adjusting to changing sea or ship conditions by simulating the next two roll periods to optimise roll damping against fuel consumption on a predictive basis.

The 120-trailer capacity, twin-propeller Stena Scotia is deployed in daily Ro-Ro services between Rotterdam and Killingholme in the UK.

“For us it is important to minimise the daily fuel consumption and related emissions,” said Dick van der Ent, energy efficiency manager at Stena Line.

“ABB guaranteed us a minimal saving potential of 3 per cent when utilising the latest generation of the DEGO system.”

ABB says that its initial installations of DEGO IV, across 10 vessels, have indicated fuel saving potential in the range of 5-7 per cent, with roll reduction of between 20-40 per cent and rudder reduction of 15-60 per cent.

“The latest generation of our DEGO system is an excellent example of the way our integrated solutions help to optimise the energy efficiency of ships, ranging from newbuildings to vessels with years in service such as Stena Scotia,” said Juha Koskela, managing director of ABB’s Marine and Ports Business.

“In a society that demands shipping becomes more sustainable, and rules and regulations on green shipping are becoming more stringent, we as ABB put great effort into helping our customers meet their needs.”{/mprestriction}
