The Kongsberg Maritime Simulation & Training department has developed a sophisticated Green Ship Engine Room Simulator (ERS) model based on a Wärstilä 12RT-flex 82C low-speed common-rail engine, built for a Panamax container ship of 4800 teu, with reefer capacity of 800.
The scenario for the simulated ship model is a modern Green Ship. A fuel efficient/low-emission container ship using well-proven, commercially available technical solutions. The simulated ship has a high normal operating speed of 26 knots and the propulsion machinery is adapted for all ambient temperature conditions, ranging from arctic (-40°C) to tropic (45°C), allowing new trading routes. The new ERS model offers highly realistic training based on these conditions. The RT Flex simulator model also includes a Sankey diagram (picture), making it easy to visualize the energy efficiency of the engine room plant.
Common-Rail System
Instead of the usual mechanically-controlled fuel injection pumps and exhaust valve drives of Wärtsilä RTA engines, the RT-flex82C has an electronically-controlled common-rail system, meaning that the engine room operation differs from that of other ships, so there is a requirement for specific training on this system. The new ERS model simulates the Wärtsilä Engine Control System (WECS) which triggers the electro-hydraulic rail valves for the respective functions, in addition to simulating a wealth of technical aspects including waste heat and thermal oil tank heating system. The model also simulates an exhaust converter of the SCR (Selective Catalytic Reduction) type, cutting the NOx emission by about 90%.
Vessel Performance System
Kongsberg also launched the Vessel Performance System as part of the new K-Chief 600 marine automation system. It provides a set of tools that enables ship owners and operators to manage their vessels in ways that are more economical and ecologically beneficial, in compliance with safety regulations.
