In order to facilitate understanding of the above technical solution of the present invention, a super tanker (Very Large vessel passenger Carrier, abbreviated as VLCC) with a ship type of 30.8 ten thousand load will be described below.
In step 101, type information, size information and hull line style of a ship are obtained, specifically, the type information may be a supertanker, and the size information of the supertanker is shown in table 1 below, and the hull line style may be referred to in fig. 12 to 14.

| Length LBP/m between two columns | 320.0 |
| Type width B/m | 60.0 |
| Depth of form D/m | 29.8 |
| Summer loading line draft T/meter | 21.8 |
| Water discharge delta/ton in summer loading line draft | 353627 |
In step 102, determining acceptable environmental conditions for vessel mooring based on mooring related specification information; specifically, according to the recommendations of international classification society IACS UR a2, the acceptable environment conditions for mooring the ship terminal are as follows:
average wind speed of 25 m/s in any direction.
A maximum flow velocity of 1 m/s acting on the bow or stern (+ -10 °).

Accordingly, the arrangement of the mooring lines 4 of the vessel when mooring at a conventional quay can be seen in fig. 1.

| Number of conventional head lines a | 2 |
| Number of conventional |
2 |
| Number m of conventional transverse cables | 6 |
| Number x of conventional cable rewinds | 4 |
| Each length of L/m | 200 |
| Minimum breaking strength delta/kilonewton | 962 |
In step 104, determining the number M of transverse cables, the number X of inverted cables, the arrangement of the transverse cables, the arrangement of the inverted cables and the length of a mooring cable 4 required by the ship according to the geometric arrangement of the conventional head cable and the conventional tail cable between the ship and a conventional wharf;
specifically, as can be seen from fig. 1, the longitudinal restraint on the ship is mainly realized by the conventional inverted cable, the conventional head cable and the conventional tail cable are mainly used for realizing the transverse restraint on the ship, the number of the conventional head cables and the number of the conventional tail cables can be merged into the transverse cables, so that 4 inverted cables are obtained, and 10 transverse cables are obtained, wherein the transverse cables comprise a head transverse cable 42 and a tail transverse cable 45, and the inverted cables comprise a head inverted cable 43 and a tail inverted cable 44. For ease of handling the transverse cables should be arranged in the region of the hull or adjacent regions parallel to the longitudinal centre line of the hull, whilst for effective restraint of the gyrating motion of the hull the transverse cables should be arranged as close to the bow or stern of the vessel as possible. The lay line is arranged close to the vessel in relation to the transverse line and is directed at as small a horizontal angle as possible to the longitudinal centre line of the vessel, for example at 15 degrees to the horizontal angle of the longitudinal centre line of the vessel.
Furthermore, the number of transverse lines and the number of reserve lines may be increased or decreased depending on the actual arrangement of the vessel mooring system, with the strength of the mooring lines 4 being adjusted accordingly. For example, if the number of the transverse cables is adjusted from 10 to 6, the adjusted minimum breaking strength of the transverse cables may be δ × 10/6 — 1603 kn, and specifically, the number of the transverse cables may be adjusted according to actual needs, but in the present embodiment, the number of the transverse cables is not adjusted.
In step 105, determining load information of the side shell mooring of the vessel and load limit information of the mooring line 4 based on the minimum breaking load δ;
in this example, the minimum breaking load δ of the mooring line 4 is 962 kn, and the design load of the outboard plate mooring may be (100% to 115%) δ, i.e., 962 kn to 1106 kn, where 1106 kn is taken; the load limit of the mooring line 4 in its operating condition may be 55% delta, i.e. 529 kn.
In step 106, the mooring device is mounted at the corresponding position of the side shell plate based on the arrangement of the transverse cables and the arrangement of the reverse cables. The mooring arrangement for installation of the side shell mooring is shown in figure 9.
According to the technical scheme, when the mooring device is arranged on a ship, compared with a mooring system such as a cable guider 49 arranged on the ship in the prior art, the overall structure of the mooring device is improved, the head cable 41 and the tail cable 46 of the conventional wharf 6 mooring are eliminated, the head transverse cable 42, the head inverted cable 43, the tail inverted cable 44 and the tail transverse cable 45 are reserved, the mooring cable 4 does not need to be pulled and guided through the cable guider 49 on the ship, and meanwhile, the mooring device is fixedly arranged on the outboard wall of the shipboard, so that the included angle formed by the mooring cable 4 for mooring the ship and the horizontal ground of the wharf 6 in the vertical plane is not larger than the preset angle, and the effectiveness of the mooring device and the operation efficiency in the mooring operation process are obviously improved.
