VISIR evaluated vs. AIS tracks

First end-to-end evaluation of VISIR vs. actually sailed ship tracks (as reported through AIS data) provided by Dimitris Zissis and his team of MarineTraffic. This will allow investigating actual optimization options taken by ships. The work is accepted for TransNav2019 and a preprint is available on Zenodo. Read here the full press release.

VISIR-1.b: the fully-open model upgrade for including ocean currents

We have just published the latest VISIR manuscript, with a thorough description of its governing equations, validation, performance, extensive case studies, videos, and a full release of the model source code (LGPL license), including user manual and install script, input and output data. The manuscript starts today its open peer-reviewing process on Geoscientific Model Development Read more about VISIR-1.b: the fully-open model upgrade for including ocean currents[…]

VISIR developments to address IMO’s ambition on low carbon shipping

International Maritime Organization‘s ambition to reduce carbon intensity of International shipping (part of MEPC.304(72)) is now addressed through new VISIR developments in the Atlantic Ocean. A web application (www.atlantos-visir.com) allows discovering optimal tracks making use of waves and ocean currents and assessing their relative EEOI savings with respect to navigation along least-distance tracks.

VISIR presented at the International Maritime Organization

Last Oct.22 VISIR was presented at International Maritime Organization in London.  The presentation was done in the frame of the Italian side-event of the MEPC-73 meeting which addressed, among others, the implementation of the initial strategy on GHG emission reduction from ships. VISIR potential for assessing energy efficiency gains of optimal ship tracks via ocean currents Read more about VISIR presented at the International Maritime Organization[…]

VISIR acknowledged in a MSc thesis at the TU-Delft (Netherlands)

VISIR source code and papers acknowledged in a MSc thesis in Aerospace Engineering at the Technische Universiteit Delft  (Netherlands). Florian Aendekerk successfully defended his thesis on “Weather Route Optimization for Oceanic Vessels” last May, 28th. Florian’s work has been carried out in cooperation with Compagnie Maritime Belge (CMB) and supported the conclusion that vessel fuel Read more about VISIR acknowledged in a MSc thesis at the TU-Delft (Netherlands)[…]

First B.Sc.-thesis in Computer Science based upon VISIR

Arturo Iafrate from the Università degli Studi di Napoli “Parthenope” successfully recoded the VISIR Matlab code into Java, adding also some new functionalities. The work is based upon the open source code downloaded from www.visir-model.net. Arturo’s thesis, defended on March 1st, 2018, was supervised by Prof. Raffaele Montella of Dipartimento di Scienze e Tecnologie.
