1. 1. Paths forward for Sustainable Maritime Transport : A techno-economic optimization framework for next generation vessels

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Julian Ulrich Hausweiler; [2023]
   Keywords : ;

   Abstract : Recently, the decarbonization of maritime transport has received increased attention, in order to align with the targets of the Paris Agreement. In 2023, the International Maritime Organization unveiled their revised greenhouse gas strategy with an ambitious target: net-zero emissions by 2050. READ MORE

3. 2. Evaluating weather routing

   University essay from Lunds universitet/Institutionen för datavetenskap

   Author : Ludvik Brodl; [2017]
   Keywords : weather routing; voyage analysis; voyage optimization; route evaluation; meteorological advice; weather factor; Science General;

   Abstract : Today it is an accepted truth that consultation and evaluation of weather models by meteorologists can help a ship navigate the sea efficiently, using the weather and sea currents in the ship's favor. However, there exists little to no studies to support such a claim. In this report, we will first validate a simulation model by statistical means. READ MORE

4. 3. High Performance Multi-Objective Voyage Planning Using Local Gradient-Free Methods

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Niklas Fejes; [2016]
   Keywords : optimization; voyage planning; local gradient-free methods; nelder-mead simplex; subplex;

   Abstract : A number of parallel gradient-free local optimization methods are investigated in application to problems of voyage planning for maritime ships. Two optimization algorithms are investigated, a parallel version of the Nelder-Mead Simplex method and the Subplex method with Nelder-Mead Simplex as its inner solver. READ MORE

5. 4. Multi-Objective Optimization of Voyage Plans for Ships

   University essay from Lunds universitet/Institutionen för reglerteknik

   Author : Waqar Hameed; [2015]
   Keywords : voyage plan; Pareto sample; direction method; multi-objective optimization; grid search; DIRECT; Lipschitzian optimization; Technology and Engineering;

   Abstract : In this thesis two methods are investigated to solve a multi-objective optimization problem for voyage planning. The first method, grid search, is a brute force search in a three-dimensional graph while the other uses the Lipschitzian algorithm DIRECT to do a continuous search along a nominal route. READ MORE

6. 5. Multi-objective optimization and Pareto navigation for voyage planning

   University essay from Avdelningen för systemteknik

   Author : Peter Nordström; [2014]
   Keywords : Multi-objective optimization voyage planning Pareto navigation;

   Abstract : The shipping industry is very large and ships require a substantial amount of fuel. However, fuel consumption is not the only concern. Time of arrival, safety concerns, distance travelled etc. are also of importance and these objectives might be inherently conflicting. READ MORE
