The world fleet will be greener, leaner and meaner in the next eight years according to DNV’s Research and Innovation Unit in their just published ‘Technology Outlook 2020’ as they follow the example of the poet Tennyson – “For I dipt into the future, far as human eye could see, saw the vision of the world, and all the wonder that would be.”  So too, the DNV team made many correct predictions in its last 2008 ‘Outlook’ (although they admit surprise that the wind energy sector developed so rapidly) which gives added weight to their latest analysis.

Researchers in the Faculty of Maritime Studies in Rijeka, Croatia, used a Kongsberg Full Mission Engine Simulator to emulate a typical single screw VLCC equipped with a direct drive MAN 5L90MC two stroke marine diesel engine while operating in various sea conditions, from calm to the extreme Force 10 condition. The purpose of the research was to investigate and analyse external sea conditions and their effects on ship’s propulsion system dynamics and operating possibilities. The resulting research paper ‘Impact of the Environmental Sea Conditions to Ship’s Propulsion Engine Dynamics’ was presented by lead researcher Vinko Tomas at the 15th International Research Expert Conference – ‘Trends in the Development of Machinery and Associated Technology’ in Prague, Czechoslovakia, 12 − 18 September 2011. Such is the sophistication of the Kongsberg simulator the research team was able to monitor the relevant propulsion engine variables and parame... [More]
