Description

FIELD OF TECHNOLOGY TO WHICH THE INVENTION RELATES [0001] The present invention generally relates to a system and method for transporting energy carriers by a vessel along a sea route between onshore energy carrier receiving facilities. PREREQUISITES FOR THE CREATION OF THE INVENTION [0002] Typically, from an offshore wind power system, a cable transmission line is, for example, laid along the seabed or underwater, and the electric power generated by the offshore power generation facilities is transmitted to the onshore power grid via the submarine cable transmission line. For example, Patent Literature 1 discloses a cable system in which, in order to lay a transmission line regardless of the seabed topography, the transmission line is laid in a floating state between several offshore power generation facilities. Furthermore, Patent Literature 2 discloses that, in order to stably supply offshore-generated electric power nationwide, a ring electric power transmission network is provided that surrounds the land and connects the offshore power generation facilities, and it is disclosed that this electric power transmission network system includes electric power transmission lines from said offshore electric power transmission network to the land. LIST OF REFERENCES PATENT LITERATURE [0003] Patent Literature 1: JP 2014-093902 A. Patent Literature 2: JP 2014-158363 A. SUMMARY OF THE INVENTION TECHNICAL TASK [0004] In this case, in traditional electric power systems, for example, to transmit electricity generated by offshore power generating plants to onshore energy receiving facilities, a cable transmission line is laid along the ocean floor or underwater, through which the electricity is transported. However, in addition to the labor-intensive and expensive installation and maintenance of cable transmission lines, such traditional systems are characterized by various disadvantages, as described below. [0005] For example, given that when it is necessary to lay cable power lines in the open sea, in particular, obtaining permission from national or local authorities is a lengthy procedure, while, due to the fact that a certain amount of time is required to carry out installation work, the time period before the commissioning of power generating plants is exceptionally long. [0006] Moreover, in the case of laying a transmission cable line in the open sea, there is a risk of adverse impact on the natural environment in the open sea or on the seabed, and therefore, it is necessary to take appropriate precautions when laying the transmission cable line, and depending on the environmental conditions, circumstances may arise that make it impossible to lay the transmission cable line. [0007] Furthermore, due to the fact that the transmission line cables are anchored to the seabed or underwater, there are no options whatsoever that exclude the possibility of transmitting electricity other than using transmission line cables. For example, in the case of transmitting electricity from offshore power generating facilities to energy receiving facilities via transmission line cables, the electricity can be directly transmitted to specific energy receiving facilities at any arbitrary point in time. Therefore, to transmit electricity from power generating facilities to any arbitrary point, it is necessary in all cases to connect to the land-based power grid, which creates the problem of low transmission efficiency. [0008] Thus, the main object of the present invention is to provide a method for efficiently transporting energy carriers, such as electrical energy, to a randomly selected installation for receiving energy carriers without using a power supply line, such as a cable power line laid along the seabed. SOLUTION TO THE PROBLEM [0009] As a result of intensive research in the field of means for solving the problems of the prior art, the author of the present invention obtained information that various problems encountered in the use of electric power transportation methods using cable power lines and the like can be solved by transporting energy carriers on a ship along a sea route from a power supply unit to an energy carrier receiving unit. Based on the obtained data, the author of the present invention proposed an idea that can find a solution to the problem of the prior art and completed the present invention. In particular, the present invention includes the following configurations or steps. [0010] A first aspect of the present invention relates to an energy carrier transportation system. The system according to the present invention mainly includes: a vessel for transporting energy carriers, equipped with energy carrier storage devices; an energy supply unit located outside the vessel for transporting energy carriers and intended to supply energy carrier to energy carrier storage devices located on the vessel for transporting energy carriers; and an energy carrier receiving unit located outside the vessel for transpor
