Control method for ship mooring stability auxiliary structure

A control method for a ship mooring stability auxiliary structure, the ship mooring stability auxiliary structure comprising a tugboat, a mechanical arm, and a magnetic chuck connected in sequence, the mechanical arm comprising a plurality of arm segments hinged in sequence, and a telescopic drive component being disposed between the two adjacent arm segments, wherein the control method comprises the following specific steps:

• S10:
• obtaining design breaking force of a ship mooring cable and ship dimensions;
• S20:
• setting tugboat auxiliary thrust, an auxiliary quantity, and an auxiliary connection position of the magnetic chuck to a ship;
• S30:
• starting the auxiliary thrust and the tugboat of the auxiliary quantity, and connecting the magnetic chuck to the ship according to the auxiliary connection position;
• S40:
• calculating post-assistance maximum tension of the mooring cable according to the ship dimensions, the auxiliary thrust, the auxiliary quantity, and the auxiliary connection position;
• S50:
• determining whether the ship is safe to moor according to the design breaking force and the post-assistance maximum tension of the mooring cable;
• and
• S60:
• if the ship is not safe to moor, adjusting the auxiliary thrust and the auxiliary connection position, and repeating steps S20 to S50 until it is determined that the ship is safe to moor.
