- 内转塔单点系统因具备类似风向标效应的旋转机制，其集成精度对设备运行稳定性和服役寿命至关重要。介绍了一种内转塔单点高精度集成的控制方法，该方法将内转塔划分成3个单体，独立建造、分步集成，并分项控制各精度点。该方法初始以月池舱中轴线为基准，优先控制主轴承的集成精度；待主轴承精度合格后，后续所有精度控制环节均以主轴承上表面为统一基准。国内某项目内转塔单点应用该方法后，塔体与浮式生产储卸油装置（FPSO）月池舱的同轴度达±3 mm，显著优于项目技术规格书中±5 mm的精度要求。该应用案例不仅验证了此方法能有效降低控制难度、提高装配精准度，更证明了内转塔单点塔体分步集成以主轴承为统一基准点这一技术路线的科学性及有效性。
Due to the rotating mechanism of the internal turret single point mooring system that resembles the weathervane effect, the integration precision during its construction phase directly determines the operational stability and service life of the single point equipment. This paper elaborated on a high-precision integration control method for internal turret single point systems, which divided the internal turret into three independent modules for separate construction, implemented step-by-step integration, and controlled individual precision points through categorized management. In the initial phase, the integration precision of the main bearing was controlled using the central axis of the moonpool as the reference. After the main bearing precision was qualified, all subsequent precision controls adopted the upper surface of the main bearing as the unified benchmark. In a domestic internal turret single point project, this method achieved ±3 mm coaxiality between the turret structure and the FPSO's moonpool, which was superior to the ±5 mm precision requirement specified in the project technical specifications. This approach not only reduced the difficulty of precision control but also enhanced accuracy. Therefore, the phased integration of the single point turret structure, with the main bearing serving as a unified reference, proves to be an effective technical solution.
