On a ship, all actions between man and machine need to be absolutely clearly defined. This is one of the reasons for the often strict hierarchy on board. The Wärtsilä propulsion control system is an innovative user interface, which improves interactions and safety aboard ships of all sizes. It unites levers and touch-screen interfaces in a clear and user-friendly design and adapts to all the possible propulsion configurations a modern ship can have. Its clearly arranged user interface allows for intuitive control in all situations and conditions. It provides users with a comprehensive view of all instruments and gives important information exactly when needed. Thus, the Wärtsilä propulsion control system guarantees a high degree of safety and quick control both at sea and in port. In addition, its sophisticated modularity makes installing, commissioning, configuration and maintenance simple and efficient, thus saving on time and costs. Thanks to a fundamental reinterpretation in terms of design, the Wärtsilä propulsion control system combines a high degree of effectiveness and elegance.
