Problems solved by technology

[0003] Due to the heavy weight of the large tonnage gravity anchor foundation, it needs to be hoisted by large lifting equipment and then installed in place during installation. However, the floating wind turbine The larger the capacity and the more complex the geological conditions of the machine site, the greater the weight of the gravity anchor foundation will be, resulting in fewer lifting equipment that can meet the requirements, and the greater the lifting capacity and the number of lifting equipment. The less, the higher the cost of its operation and appearance
And currently the lifting capacity of the lifting equipment with the largest lifting capacity in the world is 12,000 tons. For this reason, the anchor foundation of larger floating offshore wind turbines that may be designed in the future may no longer have the option of gravity anchor foundation

Embodiment Construction

[0038] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.

[0039] See Figure 1 to Figure 4 , the present invention provides a large-tonnage gravity anchor foundation installation auxiliary system, including a semi-submersible ship 100, lifting auxiliary device 200 and lifting equipment (not shown), for the auxiliary installation of the gravity anchor foundation 1.

[0040] See figure 1 and figure 2 , specifically, the semi-submersible vessel 100 is used to carry the gravity anchor foundation 1 . The semi-submersible vessel 100 should have enough space and carrying capacity to accommodate and carry other components. In specific implementation, the semi-submersible shi...

Abstract

The invention discloses an installation assistance system and method for a large-tonnage gravity type anchoring foundation. The system comprises a semi-submerged ship, a hoisting assistance device and hoisting equipment, and the semi-submerged ship is used for bearing the gravity type anchoring foundation; the hoisting assistance device is detachably mounted on the gravity type anchoring foundation; the hoisting equipment is used for hoisting the gravity type anchoring foundation in the submerging process of the semi-submerged ship, the hoisting assistance device generates buoyancy when encountering water to hoist the gravity type anchoring foundation, and the buoyancy generated by the hoisting assistance device is smaller than the gravity of the gravity type anchoring foundation. By the adoption of the installation assistance system and method for the large-tonnage gravity type anchoring foundation, the requirement of the large-tonnage gravity type anchoring foundation for the hoisting capacity of hoisting equipment can be effectively lowered, and the gravity type anchoring foundation can be smoothly installed.

Description

technical field [0001] The invention relates to the field of marine engineering, in particular to an installation auxiliary system and method for a large-tonnage gravity anchor foundation. Background technique [0002] The anchor foundation is an important part of the floating wind power equipment, which plays a vital role in ensuring the safe and stable operation of the floating wind power equipment. Compared with other forms of anchor foundation, the gravity anchor foundation has various advantages: First, The gravity anchorage foundation has enough gravity to generate pressure on the seabed, and bears the horizontal force transmitted by the mooring anchor chain through the friction between the ground and the seabed. The damage or impact of the material is much lower than that of pile anchors, grasping anchors, suction anchors and other forms of anchoring foundations; secondly, the construction of gravity anchoring foundations mainly uses concrete, sand, stones and other m...
