“…More recently, an increasing number of multi-objective weather-routing solutions have been proposed. Among them, the evolutionary algorithms have been used [5][6][7]9]. A complete review of the above-mentioned single and multi-objective weather-routing approaches has been presented in [21].…”

“…Reference systems in the open literature [3,4,7] use the navigation safety guidelines [8] for the definition of navigation constraints, which limit the areas where the navigation is allowed and not allowed based on the METOC conditions and the derived navigation conditions. In contrast to these reference systems [3,4,7] and similar to the approach discussed in [9,10], the focus of our paper is on the translation of the navigation safety guidelines [8] into a safety criterion to be minimized within a multi-criteria optimization setup. This design choice is based on the fact that the navigation safety of a route is usually determined by the vessel operator during the decisional stage.…”

“…The proposed system tries to overcome the limitations faced by the operator during decisional stage. In contrast to reference systems [7,9] where a multi-criteria ranking method is applied to sort the set of routes according to operator preferences and select the most suitable route, the proposed weather-routing system presents an alternative in the way it provides the results to the operator. The results are presented in the form of a reduced set of Pareto optimal routes.…”

This paper presents a novel weather-routing system based on a multi-criteria setup. The set of 3 conflicting criteria is: travel time, ship navigation added resistance (caused by wind and waves), and navigation risk/safety. To this aim, the International Maritime Organization (IMO) safety guidelines are exploited for the design of navigation risk criterion as a function of the METeorological and OCeanographic (METOC) and sailing conditions. This risk is directly integrated into the multi-criteria setup, as an innovative alternative to the systems proposed in the open literature. The proposed methodology is tested in a real operational scenario in the Mediterranean Sea. The obtained results show how the proposed system provides alternative routes with minimum risk to the decision-makers, as well as other different alternative routes minimizing the other criteria.

“…Harsh weather and its impact on ship routing and navigation has been discussed in [3,4,6,16]. Similarly, the impact on ships' behaviour and safety was researched in [1,10,19], the application to collision avoidance in [22] and routing of sailing vessels in [23,30,31]. In general, it might be safely stated that weather data is nowadays used in a majority of navigational and ocean engineering research problems.…”

Weather data is nowadays used in a variety of navigational and ocean engineering research problems: from the obvious ones like voyage planning and routing of sea-going vessels, through the analysis of stability-related phenomena, to detailed modelling of ships’ manoeuvrability for collision avoidance purposes. Apart from that, weather forecasts are essential for passenger cruises and fishing vessels that want to avoid the risk associated with severe hydro-meteorological conditions. Currently, there is a wide array of services that offer weather predictions. These services include the original sources – services that make use of their own infrastructure and research models – as well as those that further postprocess the data obtained from the original sources. The existing services also differ in their update frequency, area coverage, geographical resolution, natural phenomena taken into account and finally – output file formats. In the course of the ROUTING project, primarily addressing ship weather routing accounting for changeable weather conditions, the necessity arose to prepare a report on the state-of-the-art in numerical weather prediction (NWP) modelling. Based on the report, this paper offers a thorough review of the existing weather services and detailed information on how to access the data offered by these services. While this review has been done with transoceanic ship routing in mind, hopefully it will also be useful for a number of other applications, including the already mentioned collision avoidance solutions.

“…At the same time, the manner of hazardous substance storage poses a multitude of problems, particularly if it is an explosive substance (Liu, 2017). At that point it becomes necessary to define an explosion risk area (Krata and Szlapczynska, 2017). A simulation related to determining danger zones is a good method of obtaining preliminary information on the range and the impact of any possible instances of depressurization of tanks or systems transporting such substances (Ślączka, 2011), (Atkinson, 2017).…”

Nowadays, when we try to automatize all activities, there is a growing demand for energy in all forms. Increasingly we reach for new energy sources that can be problematic to store or to transport, owing to their toxicity or explosive propensity. The article examines the issues of determining danger zones occurring as a result of liquefied natural gas (LNG) release. The range of danger zones caused through LNG release depends on a multitude of factors. The basic parameter that needs to be considered is a type of the released substance as well as the manner of its release. The range of a danger zone is determined by, inter alia, the concentration of a released substance and the atmospheric conditions existing at the time when depressurization occurs. The article analyses the problem of the range of danger zones in a function of wind speed and surface roughness with a defined value of Pasquill stability for various LNG types, starting with pure methane, and ending with the so-called LNG-heavy. The difficulty of the task becomes more complicated when the analysed surface over which a depressurization incident takes place involves water. The problem deepens even further when the analysed substance possesses explosive properties. Then, apart from regular substance concentration, upper and lower flammability limit ought to be considered. Calculations were conducted with DNV-Phast software, version 7.11.
