Description

Technical Field

[0001] This invention belongs to the field of ship structure technology, specifically relating to a boarding structure and boarding method for a floating power generation platform. Background Technology

[0002] In harsh wind and wave conditions, the platform is prone to violent swaying, which affects the platform's operational stability and safety.

[0003] For embarking vessels, helicopters or pilot ladders are generally used. Helicopters require landing pads and fire-fighting facilities, resulting in higher transportation costs. Therefore, most vessels use pilot ladders. Pilot ladders are used for pilots to board and disembark vessels, typically a combination of inclined and rope ladders. Pilots risk their lives to use these ladders to provide navigation services, and accidents involving falls overboard are not uncommon. Floating power platforms have a periodic need for large numbers of operators to board and disembark, but these operators often lack the necessary skills for pilots, making the risks of boarding and disembarking even greater.

[0004] Therefore, given the frequent boarding and alighting of operators on floating power generation platforms, it is necessary to design a specialized boarding and alighting structure to ensure the safety of operators and other personnel while providing maximum convenience. Summary of the Invention

[0005] The purpose of this invention is to provide a boarding structure and boarding method for a floating power generation platform, which can be used frequently by platform operators and can provide effective safety assurance.

[0006] The technical solution of the present invention is as follows: a boarding structure for a floating power generation platform, applied to a floating power generation platform, wherein an inner harbor basin is provided on the side of the floating power generation platform, the inner harbor basin is provided with a boarding platform, and a porthole is opened on the inner harbor basin.

[0007] The internal harbor basin comprises a watertight compartment consisting of a side outer plate, a harbor basin bottom plate, a harbor basin top plate, and harbor basin bulkheads. The upper and lower sides of the side outer plate are respectively connected to the harbor basin top plate and the harbor basin bottom plate, and both sides and the opposite side of the side outer plate are harbor basin bulkheads.

[0008] The outer side plate has a door-shaped opening and is fitted with a side door.

[0009] The bottom slab of the harbor basin is equipped with a boarding platform, and the boarding platform is equipped with cable tie posts.

[0010] The distance between the bottom edge of the opening in the outer plate and the boarding waterline is greater than the draft requirement of the connecting vessel.

[0011] The width of the opening in the outer plate is greater than the width of the barge.

[0012] The width of the boarding platform should be the same as the beam of the connecting vessel.

[0013] A boarding method using a floating power generation platform boarding structure includes the following:

[0014] When the berth vessel approaches, the port doors are opened, and the floating power generation platform uses ballast water to bring the vessel to the berth waterline. Seawater then flows into the inner harbor basin through the openings in the outer hull, bringing the water level in the inner harbor basin to the same level as the sea.

[0015] The barge sails into the inner harbor basin through the opening in the outer slab and moors its moorings to the mooring bollards;

[0016] After the docking operation is completed, the docking vessel sails out of the inner harbor basin, and the floating power generation platform uses ballast water to completely remove the port gate from the seawater.

[0017] Close the side door.

[0018] The advantages of this invention are: easier boarding and extremely high safety. The side doors remain watertight and closed during non-berthing periods, thus not adversely affecting the navigation performance of the floating power platform. Boarding via the internal harbor basin maximizes the safety of personnel. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, the floating power generation platform boarding structure provided by this invention is applied to a floating power generation platform 1. An internal harbor basin 3 is provided on the side of the floating power generation platform 1, as shown in the figure. Figure 4 As shown, the internal harbor basin 3 comprises a watertight compartment consisting of side outer plates 6, a harbor basin bottom plate 7, a harbor basin top plate 8, and harbor basin bulkheads 9. The upper and lower sides of the side outer plates 6 are respectively connected to the harbor basin top plate 8 and the harbor basin bottom plate 7. Both sides and the opposite side of the side outer plates 6 are harbor basin bulkheads 9. A boarding platform 4 with a portal-shaped cross-section is installed on the harbor basin bottom plate 7 inside the internal harbor basin 3, and a mooring post 5 is provided on the boarding platform 4. A portal-shaped outer plate opening 10 is opened on the side outer plates 6, and a porthole 11 is installed thereon.

[0028] The distance between the bottom edge of the outer plate opening 10 and the boarding waterline 12 is greater than the draft requirement of the connecting vessel 2. The width of the outer plate opening 10 is greater than the beam of the connecting vessel 2. The width of the boarding platform 4 should be equal to the beam of the connecting vessel 2.

[0029] The inner harbor basin 3 is equipped with an outboard discharge device (a common device in this field) to ensure that seawater in the harbor basin is completely discharged after the side gate 11 is closed, thereby reducing the corrosive effect of seawater on the hull structure.

[0030] The present invention also provides a boarding method using a floating power generation platform boarding structure, comprising the following:

[0031] When the docking vessel approaches, the side door 11 is opened, and the floating power generation platform 1 uses ballast water to bring the vessel to the docking waterline 12. Seawater flows into the inner harbor basin 3 through the opening 10 in the outer plate, and the water level in the inner harbor basin 3 is level with the sea level.

[0032] The shuttle boat 2 enters the inner harbor basin 3 through the outer plate opening 10 and moors its mooring to the mooring bollard 5.

[0033] After the docking operation is completed, the docking vessel 2 sails out of the inner harbor basin 3, and the floating power generation platform 1 uses ballast water to make the port gate 11 completely detach from the seawater.

[0034] Close the side door 11.
