Offshore pipelines include submarine cables, offshore oil pipelines, submarine oil pipelines, marine gas pipelines, submarine gas pipelines, etc. In the process of laying pipelines for offshore engineering, the pipelines for offshore engineering need to be wound on the reel.

The minimum bending radius of pipelines for marine engineering such as submarine cables, offshore oil pipelines, submarine oil pipelines, offshore gas pipelines, and submarine gas pipelines is limited. If it is too small, the pipeline will be damaged. Therefore, the radius of the inner circle of the hose reel must be larger than the minimum bending radius allowed by the pipeline for offshore engineering, so as to prevent the hose or submarine cable from being damaged due to local bending of the hose.

At present, the inner radius of the reel used for pipeline installation in offshore engineering is fixed and cannot be adjusted. Therefore, when installing pipelines for offshore engineering of different specifications, it is necessary to arrange fillers on the periphery of the inner ring of the reel. For example, multiple foam blocks can be arranged around the periphery of the inner ring of the reel and bound to the inner ring of the reel. To increase the radius of the inner ring of the coiled coil; this method is difficult to select the appropriate radius of the inner ring of the coiled coil according to the minimum bending radius of the pipeline for different offshore engineering.
