摘要:

海上钢桩是海洋工程中常见的一种结构,常用于海洋平台导管架,海上风电装置桩基及单点系泊系统锚端等.海上钢桩的安装对整个海上工程的进程及费用都具有重大影响,其中钢桩的海上吊装作业是最重要的一环,对船舶的吊机能力有很大的要求.当钢桩超过一定长度时,倘若吊机无法将钢桩垂直起吊,则需要水平吊装至水下进行扶正.阐述了大直径超长桩的海上吊装水下扶正方案,研究了其中的关键技术难点,并以南海某海域单点系泊系统桩基打桩为工程实例,详细介绍并验证了水下扶正方案的可靠性.该方案可为大直径超长桩的海上安装提供新的思路和途径.

Abstract:

Offshore anchor pile is very common in offshore structures such as jacket platform, offshore wind turbine platform and single point mooring system, etc. The installation of anchor pile has significant effect on the cost and process for the whole engineering, in which the lifting is the most important procedure in the offshore operation because it has a great demand for the crane capacity of the vessel. When the anchor pile is too long for the crane to lift vertically, underwater horizontal upending is required in the operation. We elaborate the scheme of underwater horizontal upending for the large-diameter and ultra-long anchor pile offshore lifting and discuss the key technical difficult points. An engineering example of anchor pile installation of single point mooring system in South China Sea is given, through which the reliability of underwater horizontal upending scheme is introduced and validated. This program provides new ideas and approaches for large-diameter and ultra-long anchor pile offshore installation.

Key words: offshore engineering, anchor pile, underwater horizontal upending, rigging arrangement, remotely operated vehicle
