Sling-type pneumatic fenders are a type of marine fender specifically designed for use in ship-to-ship transfer operations, ship-to-dock berthing, and mooring operations. These fenders are characterized by their construction and the way they are attached or "slung" in place.
Construction
Sling-type pneumatic fenders are typically made of synthetic-cord-reinforced rubber sheets that are filled with compressed air. This construction allows them to float on the water surface and act as shock absorbers, protecting both ships and docks from damage during contact. The fenders are often equipped with a flange area, safety valve, and a bead ring for added strength and stability. Additionally, they may include a shackle and swivel for easy attachment and adjustment.
Applications
Sling-type pneumatic fenders are commonly used in:
Ship-to-Ship Transfer Operations: They provide a cushion between two ships during the transfer of cargo or personnel.
Ship-to-Dock Berthing: They protect both ships and docks from damage during the berthing process.
Mooring Operations: They help stabilize ships while they are moored in port.
Standards and Certifications
Sling-type pneumatic fenders are typically manufactured and tested according to international standards such as ISO 17357. This ensures that they meet the required quality, performance, and safety standards for marine applications. Many manufacturers also obtain certifications from various classification societies, such as CCS, DNV, GL, LR, and BV, to further validate the quality and reliability of their products.
