Description
A new development of the VISIR ship routing model ([Mannarini et al, Geosci. Model Dev., 9(4):1597-1625, 2016][1]) is here presented.
The first version of the model has powered an operational service in the Mediterranean Sea (www.visir-nav.com) for about 3 years. Its source-code is distributed with an open policy ([www.visir-model.net][2]).
The new developments target large ocean-going vessels (such as cargo vessels, tankers, and cruise ships) and also accounts for ocean currents. In order to effectively use currents in a graph-search method, new equations are derived and validated versus an analytical benchmark. Also, a case study is computed in the Atlantic Ocean, using surface current fields from a data-assimilative global ocean model.
The results are discussed with a focus on assessing limits and potentiality of the algorithm for solving a path optimization problem in presence of dynamic currents.
VISIR as a community model will contribute to the energy efficiency of vessel operation (IMO SEEMP) through optimization of the route duration on the basis of forecast ocean state.
