WHAT PROPULSION FOR THE SHIP OF THE FUTURE

The purpose of this article is to show why large-bore medium-speed engines like the Vasa 46 range produced by Wartsila Diesel will be an attractive main engine for the ship of the future as an alternative to the slow-speed engine that is regarded as the normal choice. It is described how this conclusion was reached by applying the latest developments in machinery technology to a 225m Panamax- size dry bulk carrier and comparing results with Vasa medium-speed diesels installations with those slow-speed engines. The study covered such aspects as Neat Fit installation, main engine foundation, electric power consumption, waste heat recovery (WHR), WHR for electricity production and heat production, the fuel oil system, annual operating costs and exhaust gas emissions.
