Description

Technical Field

[0001] This invention relates to a stern-extended gantry heavy-duty cable guide support structure and installation method for a multipurpose vessel. Background Technology

[0002] In the construction of multipurpose vessels, the stern-mounted heavy-duty guide wire is one of the most important pieces of equipment. It plays a crucial role in vessel mooring, navigation, towing, and rescue operations. During towing or rescue operations, the stern-mounted heavy-duty guide wire experiences large working loads and complex stresses, requiring extremely high strength and rigidity from its support structure. Based on the requirements of stern mooring arrangements, towing operations, and special rescue operations, and taking full account of the various loads the guide wire will experience under extreme conditions, a reasonable form and size are adopted for its support structure to meet the strength and rigidity requirements of the guide wire's working load. At the same time, combined with the stern structural form and characteristics, the guide wire support structure is optimized and connected to the stern end plate structure to form an integral whole, which is conducive to the effective transfer of its working load to the hull structure and avoids fatigue strength damage to the support structure.

[0008] The lower part consists of an open grid structure composed of a transverse web (5), a transverse panel (6), a longitudinal web (7), and a longitudinal panel (8).

[0009] Another technical solution adopted by the present invention to achieve the above objectives is: a method for installing a stern-extended portal heavy-duty guide wire support structure for a multipurpose vessel, comprising the following steps:

Based on the mooring arrangement at the stern, the size of the cable guide, and the requirements of the load and space required for equipment operation, the size and form of the support structure are designed. The box-shaped structure is aligned with the hull structure. A manhole (16) is set on the stern sealing plate (13). The lower half of the support base plate (4) is designed as an open grid structure to facilitate on-site construction, personnel passage, and maintenance.

[0011] b. Based on the load on the portal heavy-duty cable guide, the strength and rigidity requirements of its support structure are as follows: after assembling the reinforcing rib (1), transverse rib (2), support side plate (3), support bottom plate (4), transverse web plate (5), transverse panel (6), longitudinal web plate (7), longitudinal panel (8), central diaphragm (9), column support plate (10), connecting rib (12), support sealing plate (14) and wear-resistant round tube (15), they are then assembled with the extended main deck (11) and stern sealing plate (13), and aligned with the reinforcing structure of the stern sealing plate (13) to form a complete open box-shaped support structure.

[0012] c. Perform strength verification on the supporting structure together with the hull structure in the area to ensure that the overall strength of the hull structure in the area meets the relevant requirements of the specifications.
