[0022] The present invention provides a method, device, electronic equipment and storage medium for calculating the wave height of ship operation, which are respectively described below.

[0023] like Figure 1 As shown, the present invention provides a method for calculating the wave height of ship operation, comprising: S101.

[0024] It can be understood that the present invention defines the reduction factor K of the operation control wave height according to the different ship sizes and the movement characteristics of the ship under the action of beam waves and following waves, and considering the operation standard cycles specified in different ship type specifications. T， After determining the initial operating wave height of the ship, combined with the reduction coefficient, the obtained operating wave height is more in line with the actual situation, thereby achieving the purpose of accurately and specifically calculating the ship's operating wave height.

[0025] In some embodiments, determining a reduction factor for the operating wave height based on the ship type and the standard operating cycle includes: When the ship type is an oil tanker or a bulk carrier, the reduction coefficient of the operating wave height corresponding to waves of different periods in beam waves is determined based on the ratio of the operating control wave height when waves of different periods in beam waves act and the operating standard wave height with a wave period of 8 seconds in beam waves.

[0026] In some embodiments, based on the ratio of the operation control wave height when waves of different periods in beam waves act and the operation standard wave height when the wave period is 8 seconds in beam waves, the reduction coefficient of the operation wave height corresponding to waves of different periods in beam waves is determined, including: The average value of the ratio of the operating control wave height corresponding to multiple different ship loads under the same period wave to the operating standard wave height with a wave period of 8 seconds in beam sea is calculated, and the reduction coefficient of the operating wave height under the corresponding period wave is obtained based on the average value.

[0027] In some embodiments, determining the reduction factor of the operating wave height based on the ship type and the standard operating cycle further includes: When the ship type is an LNG (liquefied natural gas) ship, the reduction coefficient of the operating wave height corresponding to waves of different periods in beam waves is determined based on the ratio of the operating control wave height when waves of different periods in beam waves act and the operating standard wave height with a wave period of 7 seconds in beam waves.

[0028] In some embodiments, based on the ratio of the operation control wave height when waves of different periods in beam waves act and the operation standard wave height when the wave period is 7 seconds in beam waves, the reduction coefficient of the operation wave height corresponding to waves of different periods in beam waves is determined, including: The average value of the ratio of the operating control wave height corresponding to multiple different ship loads under the same period wave to the operating standard wave height with a wave period of 7 seconds in beam waves is calculated, and the reduction coefficient of the operating wave height under the corresponding period wave is obtained based on the average value.

[0029] In some embodiments, determining the reduction factor of the operating wave height based on the ship type and the standard operating cycle further includes: When the ship type is an LNG ship, the reduction coefficient of the operating wave height corresponding to waves of different periods in the following sea is determined based on the ratio of the operating control wave height when waves of different periods in the following sea act and the operating standard wave height with a wave period of 10 seconds in the following sea.

[0030] In some embodiments, based on the ratio of the operation control wave height when waves of different periods act in the downstream sea to the operation standard wave height with a wave period of 10 seconds in the downstream sea, the reduction coefficient of the operation wave height corresponding to waves of different periods in the downstream sea is determined, including: The average value of the ratio of the operating control wave height corresponding to multiple different ship loads under the same wave period to the operating standard wave height with a wave period of 10 seconds in the following wave is calculated, and the reduction coefficient of the operating wave height corresponding to different wave periods in the following wave is obtained based on the average value.

[0031] In some embodiments, the present invention defines the reduction factor K of the operation control wave height according to the different ship sizes and the movement characteristics of the ship under the action of beam waves and following waves, and considering the operation standard cycles specified in different ship type specifications. T， That is, for oil tankers and bulk carriers, the ratio of the wave height when waves of different periods act on the transverse waves to the standard operating wave height when the period of the transverse waves is T=8s; for LNG carriers, the ratio of the wave height when waves of different periods act on the transverse waves to the standard operating wave height when the period of the transverse waves is T=7s. When considering the effect of the following waves, the ship length is relatively large, and the ratio of the operating control wave height when waves of different periods act on all ship types to the standard operating wave height when the period of the following waves is T=10s is defined as the reduction coefficient when the following waves act. When the following waves act, the result when the period is T<8s (oil tankers and bulk carriers) or <7s (LNG ships) and when the following waves act T<10s is taken as 1.0. Generally, when the period is smaller, the reduction coefficient when the following waves act is greater than the reduction coefficient when the transverse waves act. As the period increases, when the following waves act, due to the longer length of the ship, the influence of the longer period is greater, and its reduction coefficient value decreases faster, and will be less than the reduction coefficient when the transverse waves act. At the same time, the smaller the ship tonnage, the larger the reduction factor, mainly because the smaller tonnage ship has a smaller wave size relative to the longer period, and as the period increases, the impact of the period is relatively small.

[0032] Generally speaking, the reduction factors of larger tonnage 300,000-ton ships, 150,000-ton ships and 50,000-ton oil tankers are basically the same, with small differences. The average value can be used as the reduction factor for the operating control wave height of the three tonnage oil tankers, while the reduction factor for the operating wave height of the 10,000-ton oil tanker is significantly larger than the reduction factors of the three larger tonnage ship types.

[0033] For LNG ships, although there are certain differences in the results of the three sizes of LNG ships, the change rules and magnitudes are basically the same, and the average value is taken as the operating wave height reduction factor of LNG ships.

[0034] The results of bulk carriers are similar to those of oil tankers. The average of the test results of three larger tonnage ships is taken as the reduction factor for their operating wave height. It should be noted that for different loading and unloading processes of bulk carriers, since the formula for calculating the amount of motion is the same, the reduction factor obtained is also the same. Only when the wave is acting, due to the change in the amount of motion controlled during different loading and unloading processes, the reduction factor is slightly different, but the difference is not large, so the same reduction factor is used for different loading and unloading processes.

[0035] It can be obtained that the operating wave height of oil tankers, LNG carriers, bulk carriers and barges based on the ship motion standard can be determined by the following formula, namely:

[0036] In the formula,H 4%(T) is the operation control wave height at different cycles. To regulate the standard wave height corresponding to the shorter period, KT is the standard wave height reduction factor for operation, as shown in Table 1 and Table 2 respectively for transverse waves and following waves.
