Large suction bucket jacket hoisting method
The invention relates to the technical field of ocean engineering, and particularly discloses a large suction bucket jacket hoisting method which is characterized in that when a jacket is hoisted, a crane ship and a semi-submerged ship are matched for operation, and controllable sinking of the jacket is ensured by utilizing buoyancy generated in the sinking process of the suction bucket jacket; in the process, the suction bucket jacket can be smoothly sunk to the seabed only by providing small lifting force by the crane ship, the lifting force provided by the crane ship does not need to be increased in the whole process, and a new method is provided for lifting construction of the large suction bucket jacket through the scheme that the crane ship and the semi-submerged ship are matched for operation. A crane ship and a semi-submerged ship which can be suitable for the method are easy to obtain, in the operation window period, the hoisting construction amount can be greatly increased, the situation of construction period delay is effectively avoided, meanwhile, due to the fact that the structure of the suction bucket jacket is ingeniously utilized in the method, an additional floating body structure is not introduced, and the hoisting operation efficiency is further improved.
本发明涉及海洋工程技术领域，具体公开了大型吸力桶导管架吊装方法，在吊装导管架时，起重船和半潜船配合作业，利用吸力桶导管架在下沉过程中产生的浮力保证导管架的可控下沉，在此过程中仅需要起重船提供较小的吊力便可顺利将吸力桶导管架下沉至海底，整个过程均不需要增加起重船提供的吊力，起重船和半潜船配合作业的方案，为大型吸力桶导管架的吊装施工提供了新的方法，且能够适用于该方法的起重船和半潜船较为容易获得，在作业窗口期内，能够大幅提升吊装施工量，有效避免工期延误的情况，同时，由于该方法巧妙利用了吸力桶导管架的结构，未引入额外的浮体结构，进一步提高了吊装作业的效率。
