Problems solved by technology

[0002] During the hoisting of large-scale structures in conventional marine engineering, for the sake of hoisting safety, the designed hoisting distance between the object to be hoisted and the surrounding structures is usually more than 0.5 meters. Move, lower and place, this method cannot be applied to the hoisting of large structures with smaller gaps
[0003] In some hoisting with small gaps and high precision requirements, such as FPSO (floating production storage and offloading unit) inner turret single-point hoisting into the moon pool, the hoisting clearance is usually less than 100mm. According to the conventional hoisting method, it may There is a risk of collision damage between the suspended object and the surrounding structure, and it is difficult to safely and smoothly hoist the suspended object in place

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0030] It should be noted that the moon pool 1 is a circular through hole for installing a single point mooring system in the middle of the upper deck of the FPSO.

[0031] Such as Figure 1 to Figure 10 As shown, a guide and collision protection device suitable for hoisting in a small gap is installed between the moon pool 1 and the object to be hoisted 2, including a capture and positioning guide 3, a collision buffer guide 4, an orientation guide 6 and a collision protection device 5.

[0032] Such as figure 1 As shown, the catching and positioning guide 3 is a bending piece, which is fixed on the outer edge of the moon pool mouth. The bending piece includes a steel structure...

Abstract

The invention discloses a guide and collision protection device suitable for small-gap hoisting, which is mounted between a moon pool and a hoisted object, and is characterized by comprising a capture positioning guide device, a collision buffering guide device, an orientation fine in-position guide device and a collision protection device. Meanwhile, the safety of large hoisting is guaranteed, and the risk of collision deformation of the structure is further reduced.

Description

technical field [0001] The invention relates to the technical field of marine engineering, in particular to a guiding and collision protection device suitable for hoisting in a small gap. Background technique [0002] During the hoisting of large-scale structures in conventional marine engineering, for the sake of hoisting safety, the designed hoisting distance between the object to be hoisted and the surrounding structures is usually more than 0.5 meters. Moving, lowering and positioning, this method cannot be applied to the hoisting of large structures with smaller gaps. [0003] In some hoisting with small gaps and high precision requirements, such as FPSO (floating production storage and offloading unit) inner turret single-point hoisting into the moon pool, the hoisting clearance is usually less than 100mm. According to the conventional hoisting method, it may There is a risk of collision damage between the suspended object and the surrounding structure, and it is diff...
