Rubber Fender Installation Process (Complete Guide)

 

Foreword
The installation quality of rubber fenders, as the core protective equipment of ports, docks and shipyard berths, directly determines the safety of berthing and the service life of berths. This guide systematically Outlines the entire process of rubber fender installation, covering all 21 key technical points from the initial survey to the final acceptance, providing standardized operating norms for offshore engineering projects.

 

 

 

 

I,Systematic preparations before installation

1.Work fit checks and drawing reviews
(1) 3D verification:
Use BIM technology to review the 3D model of the fender against the design drawings, with a focus on checking:
● Structural dimensional tolerances (±5mm)
● Anchor center distance error (≤3mm)
● Continuity of the reaction force transmission path
(2) Environmental fit verification:
● Calculate the matching degree between the designed vessel type (DWT) and the actual operational vessel type
● Calculate the dynamic load (E=1500kJ - 3000kJ) at a once-in-a-century tide level
2. Technical standards for foundation treatment engineering

Foundation types	Processing techniques	Quality control indicators
Steel structure base	Sandblasting rust removal (Sa2.5 grade) → Spray epoxy zinc-rich primer	Surface roughness Ra≤6.3μm, film thickness ≥80μm
Concrete base	High-pressure water gun rinse → Local carbon fiber reinforcement (when cracks >0.3mm)	Concrete compressive strength ≥C35, flatness ≤5mm/2m

3. Acceptance list of embedded parts
Bolt group torque coefficient recheck (K value 0.11 to 0.15)
Chemical anchor bolt pull-out force tests should comply with the "JGJ 145-2013 Technical Code for Post-anchoring of Concrete Structures" standard, ensuring that the pull-out force meets the minimum pull-out force required by the product technical requirements, and after reaching the minimum pull-out force, the anchor bolt should not be damaged or fall off.
Welding quality of the stop-turn fin (UT flaw detection grade I)

 

 

II,Standardized installation implementation steps

1. Precise positioning of construction
● Total station three-dimensional coordinate layout, establishing reference control network
● Holes are formed using a numerical control hydraulic drilling machine, with a hole diameter tolerance of ±1mm
● Check the hole wall cleanliness (after purging with compressed air, use the fluorescence detection method)
2. Fender body installation

3. Dynamic compensation regulation
● Set adjustable mounts (adjustable stroke ≥200mm)
● Install strain sensor monitoring system (sampling frequency ≥100Hz)

 

 

III,Typical fender differential installation scheme

Fender types	Special installation requirements	Specialized tools
Extra-large D-type fenders	Sectional hoisting and splicing (docking accuracy ≤2mm)	120t hydraulic synchronous lifting system
Floating fender	Underwater positioning welding (underwater wet welding process)	ROV underwater robot assistance
Super elastic polyurethane fenders	Temperature compensation installation (20 ° C reference temperature correction)	Infrared thermal imager monitoring

 

 

IV,High-frequency problem solution library

Typical problems	Root Analysis	Quick Response plan
Local degumming	Insufficient cleanliness of the base surface	Re-sand + apply a primer
Abnormal noise	Insufficient bolt preload	Retighten at M12=700N·m
Perpendicularity deviation	Foundation settlement	Grouting reinforcement + re-leveling

 

 

V,Acceptance technical criteria

1. Master control project
● Anchor system bearing capacity test (static load ≥1.2 times design load)
● Fender compression deformation detection (≤ design value ±10%)
● Anti-corrosion coating adhesion test (notched method ≥3 grades)
2. General items
● Seam misalignment (≤3mm)
● Uniformity of buffer layer thickness (±2mm)
● Signboard installation firmness (wind pressure resistance ≥ level 10)
