The present invention relates to an LNG bunkering design apparatus and method for evaluating the possibility of risk by analyzing major port characteristics, developing an optimal bunkering selection model for each port by setting a bunkering zone, and designing an optimal LNG bunkering arrangement based on this.

Various procedures and scenarios for LNG bunkering can be presented through the LNG bunkering design apparatus and method according to the embodiment of the present invention, and an education program for educating an operator equipped with an algorithm according to the LNG bunkering design method of the present invention; By developing a virtual trainer simulator, it is possible to ensure that LNG bunkering operations can be performed safely.

1 is a block diagram schematically showing the configuration of an LNG bunkering design apparatus according to an embodiment of the present invention.

Referring to FIG. 1 , the LNG bunkering design apparatus 100 according to the embodiment of the present invention includes a candidate area selection unit 110 , a bunkering model determination unit 130 , an input unit 150 , and a design unit 170 . can be

The candidate area selection unit 110 according to an embodiment of the present invention may select a candidate area for designing the LNG bunkering operating system. Here, the candidate area may mean a major port of a specific country, and the main port according to the present invention is a major port for LNG bunkering in consideration of the number of incoming and outgoing ships, cumulative ton class, main types of passing ships, and the size of ships (for example, , Busan, Ulsan, Incheon, etc.). The candidate areas selected by the candidate area selector 110 may additionally select a design target area through a secondary selection operation later. In another embodiment, all of the candidate areas selected by the candidate area selector 110 are It may be set as a design target area.

The bunkering model determination unit 130 according to the embodiment of the present invention determines the LNG bunkering method for the selected candidate area, and considers parameters related to at least one of bunkering capacity, quay facility characteristics, risk, and bunkering related regulations. By evaluating the determined LNG bunkering method, the LNG bunkering optimization model may be determined for each candidate area selected by the candidate area selection unit 110 .

The main factors to be considered in selecting the optimized LNG bunkering optimization model for each candidate area are the pier structure allowable load (LNG tank lorry vehicle passing review), ship folding standards according to weather class, dangerous cargo loading and It is necessary to take into account the criteria for the separation distance of passing vessels, and the criteria of port weather and water area.

As the LNG bunkering method, there are largely a TTS method (first bunkering method), PTS method (second bunkering method), and STS method (third bunkering method).

The TTS (Truck to Ship) method is based on the supply and demand of bunkering through vehicles (trucks), and is based on one 50-ton truck. It can be based on 500CMB connected to each other. The TTS method has the advantage that a small amount of LNG bunkering is possible and there is no need to install additional facilities at the pier. There are disadvantages.

The PTS (Pipe to Ship) method is a method of supplying and supplying LNG directly from a dedicated LNG storage on land to a pier through a pipe, and is a facility dedicated to performing bunkering on a target vessel and has a small limit on the amount of bunkering. The PTS method has the advantage of having a small limitation on the amount of bunkering, the need to install (buried) a separate pipe at the pier, and the disadvantages that a number of additional facilities for safety are required.

The STS (Ship to Ship) method is mostly used in the existing fuel oil (Bunker-C oil, etc.) for supplying bunkering through double banking between ships at sea through a vessel dedicated to LNG bunkering. The STS method has advantages in that a large amount of bunkering can be supplied, the need for a separate facility arrangement is low at the pier, there is a limit to the supply of a small amount of bunkering, and it is necessary to secure safety between ships during double banking.

The bunkering model determination unit 130 according to the embodiment of the present invention determines the parameters for the bunkering capacity (Bc) for each candidate area, the quay facility characteristics (Fc), the degree of risk (Ha), and the bunkering-related regulations (Br). It is possible to evaluate the above-described LNG bunkering method for each candidate area determined by taking it into consideration, and to determine an optimal bunkering model for each candidate area accordingly.

The bunkering model determiner 130 may quantify the result for each parameter and evaluate the bunkering method determined for each candidate area.

First, a method in which the bunkering model determiner 130 calculates a parameter related to the bunkering capacity Bc will be described. In an embodiment of the present invention, the bunkering capacity (bunkering required amount) must consider both the bunkering consumption by gross tonnage according to the size of the vessel and the bunkering consumption by vessel type related to the type of the vessel.

The bunkering capacity (Bc _g ) according to the size of the vessel should be evaluated based on the gross tonnage of the target vessel in the area, and the size of the vessel should have the corresponding tank capacity based on the reference bunkering tank capacity (eg, 500m ³ ). It can be determined based on the expected gross tonnage (eg, 3,000 tons of gold). In order to quantify the bunkering capacity according to the size of the vessel, it can be quantified through the Min-Max formula based on the minimum target vessel ton class and the maximum target ton class vessel possible in each bunkering method. In the method of calculating the bunkering capacity related to the size of the vessel according to the present embodiment (Bc _g = (x _a -min)/(max-min)), x _a may be the gross tonnage of the target vessel.

As an example of the present invention, the maximum scale for bunkering is evaluated on the basis of 200,000 tons, which is the largest ship currently in operation, and 0 or less is reflected as 0, and if the result value exceeds 100, the method cannot be accepted. It can be evaluated as 0 as exceeding the limit. <Table 1> below is an example of the evaluation result, and is a standard table for quantifying the bunkering capacity for the minimum vessel size of 2,000 ton class, the most frequent vessel size is 5,000 ton class, and the maximum vessel size is 80,000 ton class.

method Min Max 2000 5000 8000 STS 3000 200000~ 0 0.01 0.39 PTS 0 200000~ 0.01 0.025 0.40 TTS 0 3000 0.40 1.0 0

The bunkering capacity (Bc _t ) according to the type of vessel can be calculated based on the sensitivity of each bunkering method that reflects the fuel consumption and navigation distance for each type of vessel. In the case of sensitivity calculation, it should be calculated by correcting the fuel consumption (BC) of the target ship and the average sailing distance (VL) from the target port to the next port.

In the method of calculating the bunkering capacity according to the type of vessel (Bc _t = C _L x V _D ), C _L is a coefficient according to the daily fuel consumption, and V _D is a coefficient according to the required sailing distance.

Next, a description will be given of a method by which the bunkering model determination unit 130 calculates a parameter related to a pier facility characteristic (Fc).

The characteristics of the pier can be classified into four types: gravity pier, pier pier, dolphin pier, and floating pier. Gravity-type piers are berthed directly on the pier and the load strength is strong for loading cargo on the upper part of the pier. However, it is a case where access is limited to a wharf mainly for oil cargo, and a floating pier or berth is a case where a vessel is berthing or mooring at sea.

The bunkering model determiner 130 may calculate the parameters according to the characteristics of the pier facilities in consideration of the pier characteristics (allowable load of the pier) of the target area, the accessibility (Ac), and the facility possibility (Ip).

According to a more specific embodiment of the present invention, the bunkering model determining unit 130 checks the bunkering method to be applied to the target area in consideration of the accessibility (Ac) and the facility possibility (Ip), and the confirmed bunkering method for the target area A quantified numerical value according to the quay facility characteristics of the target area may be calculated by referring to the quantification table according to the preset bunkering method and the pier characteristics in consideration of the characteristics of the pier and the bunkering method.

Next, a method in which the bunkering model determiner 130 calculates a parameter related to a hazard (Ha, Hazard analysis) will be described.

As for the parameter related to the degree of risk, the diffusion range during gas outflow during LNG bunkering according to the LNG bunkering method of the corresponding area determined by the bunkering model determination unit 130 is a major factor to be considered. More specifically, the bunkering model determiner 130 may calculate a parameter for the degree of risk based on information about the distance between the valves, the amount of leakage (leakage per second), and the upper and lower limits of explosion when gas is leaked.

2 is a simulation screen showing a diffusion range when gas is leaked during LNG bunkering according to an embodiment of the present invention. The bunkering model determiner 130 according to the present embodiment may display the result of the risk parameter calculated for the corresponding area as a red zone, a yellow zone, and a green zone. For example, the red zone may be an area defined by a diffusion range within 3.1 to 3.9 m, the yellow zone may be an area defined by a diffusion range within 6.8 to 12 m, and the green zone may be an area defined by a diffusion range of 27 m or more. have.

Next, a description will be given of a method in which the bunkering model determination unit 130 calculates parameters related to bunkering rules and regulations (Br, Bunkering rules and regulations).

As for the parameters for bunkering-related regulations, the hazardous area classification regulations are a major factor to consider. According to an embodiment of the present invention, as a place where hazardous substances are continuously present in a normal state, it is not limited to the inside of the fuel tank, but a place such as all pipes, fuel pipes, and facilities of a pressure relief or venting device for a fuel tank is Zone 0 Designated as (category 1), a place where hazardous substances are likely to exist under normal conditions, such as a tank connection area, a fuel storage area, an area including a fuel preparation room with ventilation system, and a timetable tank outlet, are designated as Zones. It can be designated as 1 (category 2), and places where hazardous substances can exist for a short time under abnormal conditions, such as those including places within 1.5 m around an open or semi-enclosed area of Zone 1, etc. category 3). 3 is a diagram illustrating a classification of a dangerous area with respect to a target area according to an embodiment of the present invention.

4 is a diagram illustrating a state in which danger zones are set according to a bunkering method such as a PTS method according to an embodiment of the present invention.

The bunkering model determiner 130 may determine the final LNG bunkering optimization model by applying different weights to the calculation results of each parameter calculated as described above. Here, the different weights to be applied to the respective parameters may be weights calculated by researching in advance for experts.

According to an embodiment of the present invention, the bunkering model determining unit 130 determines the LNG bunkering optimization model according to the final result derived by applying a predetermined weight to the calculation result for each parameter, wherein the bunkering model determining unit 130 is It may be implemented to determine the corresponding LNG bunkering optimization model of the target area in consideration of the LNG bunkering model reference table for each numerical range of the derived result stored in advance.
