Abstract
A reeled pipe storage reel with a large diameter hollow cylindrical shaft, reel shaft bearing support structures installed on the vessel, and a reel drive arrangement mounted on the vessel. The shaft across the width of the reel provides structural stiffness and consistent alignment of the bearings on each end of the shaft. Each end of the shaft extends beyond the reel and includes a section for connection to a lifting sling, a section for the machine bearing surface, and a section for absorbing initial contact with the vessel during installation. The reel shaft bearing support structures on the vessel include a fixed portion to match the bearing area of the reel shaft and a movable portion to absorb initial contact during installation of the reel. The reel drive arrangement is located on linkages so they can be manipulated in the plane of the reel flange for movement into engagement with the drive gear on the reel flange.
