Description

Fuel supply management system and fuel supply management method thereof The present disclosure relates to a fuel supply management system and a fuel supply management method thereof. Generally, ship fuel is used according to the direct orders of the shipping company operating the vessel. Various regulations and policies are being implemented globally to mitigate climate change and reduce greenhouse gas emissions. Consequently, as regulations on greenhouse gas emissions from ships become stricter, shipping companies are being required to use eco-friendly fuels alongside fossil fuels for vessel operations. Meanwhile, with the imposition of carbon taxes becoming a reality and the variety of eco-friendly fuels increasing, monitoring which fuels were used, when, and how during ship operations, as well as systematic management of fuel usage, is becoming increasingly important. However, to date, systems and related technologies capable of monitoring and managing fuel usage on ships have not been developed, and therefore, the development of such technologies is required. FIG. 1 is a block diagram of a fuel supply system for a ship according to one embodiment. FIG. 2 is a flowchart of the operation of a fuel supply system of a ship according to one embodiment. Throughout the specification, the same reference numerals refer to the same components. This specification does not describe all elements of the embodiments, and general content in the art to which the disclosed invention pertains or content that overlaps between embodiments is omitted. The terms 'part, module, component, block' used in the specification may be implemented in software or hardware, and depending on the embodiments, a plurality of 'parts, modules, components, blocks' may be implemented as a single component, or a single 'part, module, component, block' may include a plurality of components. Throughout the specification, when a part is described as being 'connected' to another part, this includes not only cases where they are directly connected but also cases where they are indirectly connected, and indirect connections include connections made via a wireless communication network. Furthermore, when it is stated that a part 'includes' a certain component, this means that, unless specifically stated otherwise, it does not exclude other components but may include additional components. Throughout the specification, when it is stated that a component is located 'on' another component, this includes not only cases where a component is in contact with another component, but also cases where another component exists between the two components. Terms such as "first," "second," etc., are used to distinguish one component from another, and the components are not limited by the aforementioned terms. Singular expressions include plural expressions unless there is an obvious exception in the context. In each step, identification codes are used for convenience of explanation and do not describe the order of the steps; the steps may be performed differently from the specified order unless a specific order is clearly indicated in the context. Due to the strengthening of environmental regulations, ships must report the greenhouse gases emitted annually based on the fuel used. The limits on Greenhouse Gas Intensity (GHG Intent) are scheduled to be gradually strengthened based on 2020, as shown in Table 1 below. Year2020202520302035204020452050ReductionReference2%6%14.5%31%62%80%Greenhouse gas intensity (GHG Intensity) [gCO2eq/MJ]91.1689.385.777.962.934.618.2 Taking an ammonia carrier using an ammonia engine as an example, if 100% of the fuel used is grey ammonia, which has a high greenhouse gas intensity, a carbon tax must be paid starting in 2025; however, greenhouse gas intensity can be controlled through a combination of grey ammonia and green ammonia. For example, the ratio of grey ammonia and green ammonia usage can be controlled as shown in Table 2 below. 2025~20292030~20342035~20392040~2045Gray ammonia (MT)8,300(83%)8,000(80%)6,200(62%)4,900(49%)Green ammonia (MT)1,700(17%)2,000(20%)3,800(38%)5,100(51%) As such, when using both eco-friendly fuels (also known as green and blue fuels) and fossil fuels for ship operations, technology capable of managing the usage of each fuel is required, and such technology may become important in the future. Accordingly, the disclosed invention aims to provide a fuel supply management system and a fuel supply management method capable of supplying eco-friendly fuel at a level that avoids carbon tax and managing the usage of eco-friendly fuel and fossil fuel, taking into account that eco-friendly fuel currently has low price competitiveness compared to fossil fuel as fuel for ships and that regulations for greenhouse gas reduction are scheduled to be implemented in stages in the future. In addition, the fuel supply management system and fuel supply management method of the disclosed invention can provide technology capable o
