Description

TECHNICAL FIELD

[0001] The utility model relates to the field of ship, especially a kind of applied to double-curved surface mooring side door structure. BACKGROUND

[0002] Mooring side door is mainly used as the passageway for personnel access when ship is berthed in port unloading wharf, which is particularly important in loading and unloading cargo, passenger boarding and disembarking, etc., to avoid the risk of falling directly into the water from the side of the ship. A side door is usually installed on the side of the ship to allow personnel to enter or exit the ship through the door.

[0003] The common installation method is to select a design reference point on the design model and establish a design coordinate system according to the reference point; select the opening position of the side door on the design model to obtain the design coordinates of the opening point, and calculate the actual coordinates of the actual opening point on the corresponding position of the ship body through coordinate transformation. The installation position of the side door on the ship is determined according to the actual coordinates, and then the structure is modified on site before installation.

[0004] The common side door installation structure is a plane structure, which can be pre-drilled through cutting program during the ship body structure cutting stage, and then slightly modified after the segments are closed to install. This installation method is commonly used for installing plane structure side doors.

[0005] However, the side doors on the sides of the current SOV wind power operation mother ship and PSV platform support ship are generally common on curved structures. If the current plane structure side door installation method is used for installing curved side doors, the traditional installation method needs to be continuously modified due to the stress influence and deformation after heat welding during the welding process, which requires high process requirements during installation. Once the deformation is corrected, the difficulty is dramatically increased and the ship body structure is affected, and the structure is severely deformed after too much correction, which affects the appearance of the ship body structure and consumes time and labor.
