The submarine cable basket is made of steel construction. It is a spatial structure and not a carousel-type basket. The overall dimensions of the cable basket are 12.3 x 12.3 x 6.1 meters. The submarine cable is wound diametrically inside this steel structure. The total length of the cable is 22 km. The net weight of the load is 635,874 kg, and the gross weight is 720,874 kg.
This load will be offloaded onshore from the hold of a general cargo vessel using the vessel crane with a hook block capacity of 2,500 tons (2 x 1,250 tons). The basket has eight (8) lifting pads (or lifting lugs) along the diameter (D = 4.770 m), each rated at 150 tons. The vessel crane lifting arrangement using a single 1,250-ton hook (double wire rope sling or grommet) has been considered in the project. It is planned to attach two double slings to each hook horn.
Our question is that, as a second option, it is necessary to design a spreader beam.
Please recommend a typical metal structure for the spreader beam design.
The spreader beam must be suitable for the load structure.
Thank you.
