Evaluation and optimization of the parameters of marine transport systems, which operate in polar... more Evaluation and optimization of the parameters of marine transport systems, which operate in polar regions, is an important research field nowadays. Especially it’s important in case of oil and gas transportation. Current practice shows that configuration of the transport system (the number and characteristics of gas carriers or oil tankers, capacity of shore storage etc.) should be determined in the early stages of field development. Simulation modeling of marine transport systems is an effective method to optimize configuration and characteristics of the transport system in the early stages of field development. This paper is devoted to simulation of marine transport systems, including examples of modeling of LNG transportation from the field in the Barents Sea at various distances using specially developed simulation model. Particular attention is paid to the influence of ice conditions severity on different economic indicators. The article also contains a comparison between tradi...

Abstract Offshore development and growing prospects of commercial shipping in the Arctic pose the... more Abstract Offshore development and growing prospects of commercial shipping in the Arctic pose the challenge of optimal ship routing in ice. Route selection in spatially distributed ice conditions significantly affects the voyage time and determines the efficiency of shipping. Most of the applied methods of ice routing solve the problem of a single vessel route selection without considering icebreaker support. At the same time, the real practice of ice navigation is closely connected with icebreaker assistance. It allows reducing the voyage time and fuel consumption, while having additional costs for icebreaker services. Such opposite trends set an optimization task that has not been studied in detail before. In this article, we presented the formulation of a Single Vessel and Icebreaker Assisted Ice Routing optimization problem in non-stationary ice conditions. We considered the icebreaker assistance as an integral part of the overall route optimization problem, and used the economic criterion to optimize both ship route and amount of icebreaker involvement. The article contains the adapted mathematical formulations of classical graph-based and wave-based routing problems in order to consider icebreaker assistance. To prove the practical applicability of these formulations, we developed special subject-oriented research software and implemented there both graph-based (Dijkstra, A*) and the wave-based ice routing methods. Using this developments, we conducted several case studies and made the analysis of strengthens and weaknesses of the alternative routing methods in case of ice operation. The results of the study may serve an additional step to the practical implementation of ice routing technologies and planning of icebreaker resources.

The main idea of the approach is to synthesize geographic information system (GIS) technologies, different shipbuilding disciplines, fleet planning instruments and agent-based dynamic simulation models in an integrated software framework on the basis of object-oriented programming. Vessel operation is described as the movement and interaction of independent ships in GIS environment within the framework of the simulation model. MTS operation combines vessel operation itself (routing, determination of speed and fuel consumption, icebreaker escort, etc.) with plenty of external entities (port infrastructure, ice channel freezing process, offshore platform operation, etc.) that could be described as systems with comprehensive logic and physical behavior. Such integration provides a new quality of MTS simulation that allows considering complex inte...

All these features should be considered when solving the problem of ship route optimization in ice. In this paper, we propose the modifications of the well-known graph-based and cell-free (wave-based) mathematical methods of path finding to adapt them to the problem of route optimization in dynamic ice conditions considering all above-mentioned features. We formulated the versatile cost function that involves such factors as the total voyage time, fuel consumption, freight rates of ships and risks of ice operation. The optimization task is set in such a way to allow finding the route segments where the icebreaker assistance is economically proven and optimize ...

I most studies, the Arctic is mainly associated with ice c onditions, but it is not the only factor that influences the desig n of platform supply vessels (PSV) and corresponding marine trans port systems (MTS) for this region. The structure of car go flow (i.e. its distribution by cargo types) affects the supply s stem significantly. It defines the level of utilization of vessel capacity that determines transport efficiency. At the same t ime, the literature represents this aspect poorly. This paper describes an approach to optimize supply fleet configuration by the criterion of total cost consid ering both non-stationary ice conditions and structure of carg o flows. The cargo-flow-oriented design concept incorporates the detailed calculation model of PSV and the special tactical p l nning algorithm. PSV model allows c...

Despite active development of water and land natural gas vehicles, practical approaches for obtaining appropriate estimates in a wide range of characteristics of cargo tanks have not been previously published.The objective of this work is to analyze LNG losses in road, rail and ship tanks (with a capacity of up to 5600 m3), as well as in tank containers, provided that LNG is stored with an overpressure of about 5–7 atmospheres.In the work, numerical modelling was used as a method. The evaporation process of LNG is described using models of heat exchange between the liquid phase of LNG, its vapours, as well as a cargo tank and the external environment. This makes it possible to simulate the behav...

Assessing the value of all parts of the supply chain is an important component of solving the problem of optimizing transportation costs for both consumers and LNG suppliers. In connection with tightening of environmental requirements regarding bunker fuel, the task of optimizing the supply of LNG for water transport by the cost of transportation becomes particularly relevant.The objective of the study is to develop a universal approach to estimating the cost of transporting low-tonnage LNG for bunkering vessels in the Russian Federation.The research methodology is focused on the analytical method based on a system-structural approach.As part of the departmental project of the Russian Ministry of Industry and Trade «Development of gaspowered fleet for navigation in coastal waters and inland waterways», the authors developed technical and economic models for calculating the unit cost of LNG transportation by r...
