Novel process for integrally prefabricating and hoisting herringbone frame of deepwater jacket
The invention discloses a novel process for integrally prefabricating and hoisting an inverted V-shaped frame of a deepwater jacket, which comprises the following steps of: S1, placing a plurality of cushion piers on the land, and measuring and leveling; s2, bottom horizontal pieces are laid on the leveled cushion piers, and then the bottom horizontal pieces and the cushion piers are fixed; s3, herringbone frames are fixedly installed on the two sides of the fixed bottom horizontal piece correspondingly; s4, a fixed connecting pipe is installed between the inverted-Y-shaped frames; and S5, overall hoisting is conducted on the structure. The high-altitude welding work of the herringbone frame and the bottom horizontal piece is transferred to the ground, the high-altitude hoisting frequency is reduced, the construction difficulty is lowered, the construction risk is lowered, the construction period is shortened, and the construction technology is connected with international jacket design and construction rails, so that the overseas market competitiveness is improved.
本发明公开了一种深水导管架“人”字架整体预制吊装新工艺，包括以下步骤：S1：在陆地上摆放多个垫墩，并进行测量调平；S2：在调平完毕的垫墩上，铺设底部水平片，再将底部水平片与垫墩固定；S3：在固定完毕的底部水平片的两侧分别安装固定“人”字架；S4：在“人”字架之间安装固定连接管；S5：对上述结构进行整体吊装。本发明将“人”字架与底部水平片高空的焊接工作转移到地面进行，减少了高空吊装次数，降低了施工难度，降低了施工风险，缩短施工周期，并且，这种施工工艺与国际上导管架设计、建造接轨，有利于提高海外市场竞争力。
