Background
In deepwater oil and gas development, the ocean pipelaying operation is more and more, and the importance is more and more prominent. Tensioners are specialized equipment for marine pipelaying operations and play an important role in the laying of pipelines (e.g., petroleum pipelines, umbilicals, etc.). The contact area between the four-track tensioner track and the pipeline is large, the surface stress of the pipeline is small, the pipeline is well protected, and the four-track tensioner track is mainly used for laying flexible pipes and umbilical cables. However, the umbilical ends all have a connector UTA assembly that is typically 2.5m x 1m or larger in size, beyond the tensioner lay range. At the moment, the upper track assembly of the tensioner is required to be opened, the umbilical cable is placed into the tensioner, then the upper track assembly is closed, and the upper track assembly is locked with the tensioner frame through the bolt positioning oil cylinder to form a whole. Four caterpillar bands clamp the umbilical cable together in the laying process.
In actual operation, the upper crawler assembly is not in a horizontal state but slightly inclined in the ascending process, and the reason is caused by factors such as accumulated errors of machining. When the upper crawler assembly is closed, the upper crawler assembly cannot be accurately aligned with the positioning hole, and all the upper crawler assembly has deviations of different degrees.
