2. Waste heat recovery in a cruise vessel
Abstract : In three studies of a cruise ship the author has investigated waste heat recovery (WHR)from exhaust gases using an organic Rankine cycle (ORC), and also mapped the energyand exergy flows within the ship. Data were collected from the ship’s machinerysystem for a total extent of one year, and this data were used for simulations andenergy calculations. READ MORE

3. The Regulation of Global SOx Emissions from Ships: IMO proceedings 1988-2008
Abstract : MARPOL Annex VI regulates air pollution from international shipping. Emissions of sulphur oxides (SOx) are regulated through a global limit for the sulphur content of bunker fuels (referred to as a global cap) as well as a stricter limit in particularly sensitive areas, referred to as SOx Emission Control Areas (SECAs).

5. Particle Emissions from Ships
Abstract : Since 1st of January 2015 ships operating in sulphur emission control areas (SECAs) have to use marine fuels with a fuel sulphur content less than 0.1 %m/m. This regulation forces the ship owners to make a fuel shift and use low-sulphur marine fuel oils, use alternative fuels or use scrubbers on-board their ships. READ MORE
