A turbocharged diesel engine numerical model, suitable for real-time ship manoeuvre simulation, is presented in this paper. While some engine components (mainly the turbocharger, intercooler and manifolds) are modelled by a filling and emptying approach, the cylinder simulation is based on a set of five-dimensional numerical matrices (each...

The scientific analysis presented in this paper aims at studying some maritime technical solutions for the electric energy generation and delivery to ships moored in port by means of LNG fueled generators installed onboard a floating unit. Two different scenarios regarding the LNG supply chain are supposed and some options for producing cleaner...

The paper presents an original variable layout steam plant for the Waste Heat Recovery (WHR-VL) from marine dual fuel (DF) engines, designed considering the different exhaust gas stack temperature limits, depending on the engine fuel type: generally no less than 160 °C for diesel oil and without limits for natural gas (NG). Using diesel oil, a...

The present study deals with the computational simulation of a marine four-stroke dual-fuel engine, working both in diesel and natural gas modes, with a particular focus on the turbocharger system behaviour. The engine model, developed by the authors, was implemented as a computer code and used to compare the performance of the engine when...

The study aims to investigate the effects of the steam plant components deterioration in a marine Waste Heat Recovery (WHR) system. WHR technology can significantly improve the energy efficiency of merchant ships, because it allows to recover thermal energy from the exhaust gas of the main diesel engines, in order to produce electric energy...
