[0002] Steel cylinder cofferdam island building technology is a method for quickly building artificial islands in the sea. Large-diameter steel cylinders are one of the main components of artificial island cofferdams. At present, during the construction of artificial island cofferdams, steel cylinders are usually made in a prefabrication plant and then transported to the artificial island construction site by transport ships.

[0003] Steel cylinder structures are mostly constructed at sea. Their processing plants are far away from the construction areas, so sea transportation is inevitable. Steel cylinders have large wind-exposed areas and thin walls, so they are very easy to deform during transportation due to wind loads, hull shaking, or even unstable placement, thus causing structural damage.

[0004] Therefore, a marine transport fixture is proposed. Utility Model Content
