Methodology for planning transportation and containerized cargo unloading in off-port conditions

A methodology for planning the transportation and unloading of containerized cargo in off-port conditions, aimed at achieving the most labor-efficient result is presented in the paper. The effectiveness of using maritime transport facilities for transportation largely depends on the availability and technical condition of ports and port facilities. The study of ways to prepare an unequipped seashore for the organization of temporary transshipment points is of urgent importance due to the constant need to carry out supply transportation to Arctic destinations. In the specific conditions of the Russian Federation Arctic zone, a special transportation subsystem is formed by regular northern (expeditionary) delivery. Despite a significant amount of scientific research in the field of transport support, the specific tasks of scientific substantiation of transport and technological transportation systems in off-port conditions are currently insufficiently investigated. To solve the problem under consideration, it is necessary to develop new technical and technological solutions. Modern conditions for the cargo transportation implementation generally involve the use of two technological schemes for transporting containerized cargo units from the vessel hold to the coastal zone at each of the destinations by moving each individual unit using a pontoon or helicopter. To improve the transport and technological transportation system efficiency in off-port conditions, in addition to the existing ones, an alternative scheme based on the use of self-disassembling pontoons (lighters) when unloading cargo on an unequipped coast is proposed. The methodology for planning the transportation and unloading of containerized cargo in off-port conditions is based on the fact that the particular object of research is technological schemes for transporting certain volumes of batches of containerized cargo units of various categories, implemented within a given destination. The initial data and design characteristics used in the methodology implementation, as well as the structure of the developed methodology described in the form of a flowchart are presented in the paper. The methodology calculates a complex preference indicator for each technological scheme under consideration. The considered technique allows us to determine the most preferred technological scheme from a set of alternative schemes.
