Although these are significant fuel savings, this is still not enough to effectively respond to the challenges for zero GHG emissions of the maritime industry. With the goal of demonstrating that even higher energy reduction and drastic reduction of emissions...

... treatments have been compiled, but deciding which treatment to use is not trivial. Underwater noise reductions generally cannot be achieved through selection of a single treatment from a catalog. Rather than selecting treatments from a list, stakeholders should look to reduce underwater noise by choosing...

... from renewable sources (hydro, wind, or solar) is seen by many as the most promising option to deliver the desired GHG reductions. However, renewable energy is a scarce resource that gives a much larger GHG reduction spent within other sectors. This study explores how to reach the IMO 2050 GHG targets...

... by 50% compared to 2008. To reduce GHG emissions there are five main technical and operational measures: hull design; power and propulsion; alternative fuels; alternative energy sources; and operations. In this paper we focus on the potential reductions through hull design, i.e. length and hull shapes...
