Overview

When a ship berths or is moored, due to the effects of waves and wind, the hull and berth surface are pushed and frictional. A fender is a device that prevents the hull and berthing structures from being damaged by such forces. In particular, when a large ship berths, a huge amount of force is generated, so it is necessary to securely fix the fender body in order to absorb the berthing energy more efficiently.

Implementation

Hardlock Nut Application
  • Nut tightening points of “post-installed anchor bolts” for concrete blocks in the bay.
  • Places that require proper torque management because the material of the fender is rubber.
  • Places where spot welding (especially underwater welding) was used → Use of HLN eliminates the need for welding.

Improvement

  • Safe and reliable fastening with proper torque is now possible.
  • Construction time can be greatly reduced, eliminating the need for welding equipment and underwater welding technicians.
  • Construction costs have been significantly reduced.
  • The maintenance cycle has been greatly extended, and the maintenance cost has been reduced.
