Kongsberg’s Maritime Simulation & Training department has developed a new [I]Green Ship Engine Room Simulator[/I] (ERS) model, based on a Wärtsilä 12RT-flex 82C low-speed common-rail engine.
The system is built for a Panamax con- tainer ship of 4,800 TEU, with reefer capacity of 800.
The scenario for the simulated ship model is a modern fuel efficient / low- emission ‘green’ container ship using com- mercially available technical solutions.
The simulated ship has a high normal operating speed of 26 knots and the propul- sion machinery is adapted for all ambient temperature conditions, ranging from Arctic (-40C) to tropic (45C), allowing for the introduction of new trading routes.
The new ERS model offers training based on the above conditions, and includes a Sankey diagram display which Kongsberg says makes it easier to visu- alise the energy efficiency of the engine room plant.
“Although many Kongsberg Maritime ERS models offer Green Ship functionali- ty, the RT-flex model features the most comprehensive fuel efficiency and emis- sion reduction functionality that we have developed so far,” explained Leif Pentti Halvorsen, product manager for engine room and cargo handling simulators, Kongsberg Maritime.
"Our increased focus on Green Ship simulation is a result of higher interest from environmentally conscious owners, who will be using more efficient engines like the Wärtsilä 12RT-flex in the future."
Instead of the usual mechanically-con- trolled fuel injection pumps and exhaust valve drives of Wärtsilä RTA engines, the RT-flex82C has an electronically-con- trolled common-rail system, meaning that the engine room operation differs from that of other ships and requires specific training.
