Maintenance & Replacement of Existing Jetty Fender and Bollard

Jetty fenders and bollards are critical components of marine structures, designed to absorb impact forces from vessels and secure mooring lines. Over time, they degrade due to constant wear, environmental exposure, and mechanical stress, necessitating maintenance or replacement to ensure operational safety and efficiency.

1. Maintenance of Jetty Fenders and Bollards

Regular maintenance helps extend the lifespan of fenders and bollards and prevents sudden failures. Key maintenance activities include:

A. Inspection

Visual Checks: Look for cracks, deformations, corrosion, or wear.
Structural Integrity: Assess bolts, welds, UHMW PE Pad, chain system, anode, and anchor points for looseness or damage.
Material Degradation: Check rubber fenders for hardening, tearing, or UV damage.

B. Cleaning & Lubrication

Remove marine growth (barnacles, algae) and debris.

C. Minor Repairs

Tighten loose bolts and replace corroded fasteners.
Apply anti-corrosion coatings to metal components.

2. Replacement of Jetty Fenders and Bollards

When maintenance is no longer sufficient, replacement becomes necessary. The process involves:

A. Assessment & Planning

Visual Checks: Look for cracks, deformations, corrosion, or wear.
Structural Integrity: Assess bolts, welds, UHMW PE Pad, chain system, anode, and anchor points for looseness or damage.
Material Degradation: Check rubber fenders for hardening, tearing, or UV damage.
