Project Overview
We are proud to present a successful marine infrastructure project completed for a new client in El Salvador. The project involved the production and delivery of:
- 568 pcs Custom Square Rubber Fender (250 × 250 × 4000L mm)
- 166 pcs Cell Fender SUC500H
This order required technical customisation, mould modification, performance verification, staged shipment planning, and strict quality control. The successful execution of this project demonstrates our engineering capability, manufacturing flexibility, and commitment to long-term partnerships in the marine protection industry.
Initial Contact and Technical Evaluation
The cooperation began when the client contacted us via WhatsApp and shared their technical drawings for review. After a detailed examination of the submitted drawings, our engineering team identified that the Square Rubber Fender (250 × 250 × 4000L) dimensions differed slightly from our standard production specifications.
While we maintain a wide range of standard moulds, this particular size required custom production and mold modification to fully meet the client’s structural and installation requirements.
After internal technical evaluation and production feasibility analysis, we confirmed that we could manufacture the fenders according to the client’s exact dimensions. However, mold adjustment would be necessary to ensure dimensional accuracy, structural integrity, and long-term performance reliability.
Given the large order quantity of 568 units, we made a strategic decision to undertake the mold modification cost ourselves. This reflected our confidence in the project and our willingness to invest in building a long-term partnership.
Technical Proposal and Performance Confirmation
Following mold feasibility confirmation, we provided the client with detailed technical documentation, including:
- Material specifications
- Physical and mechanical performance parameters
- Compression deflection performance data
- Reaction force and energy absorption values
- Production tolerances
For the Cell Fender SUC500H, we supplied full performance charts and standard test references to ensure compliance with international marine engineering requirements.
The client demonstrated a highly professional and efficient working attitude. After reviewing our technical proposal and performance data, they quickly approved our solution and confirmed the order without delay. Their decisive communication significantly accelerated the project timeline.
Production Arrangement and Mold Modification
Upon receipt of the advance payment, we immediately initiated:
- Mold modification for the custom square fender
- Raw material procurement
- Production scheduling
- Quality control planning
The mold modification process was handled by our in-house tooling team to guarantee precision and durability. Strict dimensional calibration was performed before full-scale production began.
During production, we implemented:
- Raw material inspection
- In-process dimensional control
- Vulcanization parameter monitoring
- Surface finish inspection
- Hardness and physical performance testing
Our production team worked under a compressed but carefully controlled timeline to meet the client’s delivery requirements without compromising product quality.
Shipment Planning and Logistics Execution
Due to the total volume of the project, shipment was arranged in four separate batches, totaling 10 × 20GP containers.
The shipment planning required careful coordination between:
- Production scheduling
- Warehouse management
- Container loading optimization
- Freight forwarding arrangements
- Port documentation compliance
All fenders were delivered to the client’s designated seaport within the agreed timeframe.
Each batch was inspected prior to dispatch to ensure:
- Correct quantity
- Proper marking
- Secure packaging
- Dimensional compliance
The staggered shipment plan helped the client manage on-site installation progress while maintaining steady supply.
Quality Inspection and Certification
Before shipment, all rubber fenders underwent comprehensive factory inspection procedures. Testing included:
- Hardness (Shore A)
- Tensile strength
- Elongation at break
- Compression performance
- Visual surface inspection
A complete Factory Inspection Report and Quality Certificate was issued and provided to the client for each shipment batch.
The client expressed strong satisfaction upon reviewing the inspection documentation and final product quality. Their positive feedback reinforced our confidence in both our manufacturing standards and quality control systems.
Technical Features of the Supplied Products
Custom Square Rubber Fender (250 × 250 × 4000L)
- High wear resistance
- Excellent compression resilience
- Long service life under cyclic loading
- Designed for quay wall and dock edge protection
- Stable structural performance
Cell Fender SUC500H
- High energy absorption with relatively low reaction force
- Suitable for medium to large vessel berthing
- Proven durability in harsh marine environments
- Compatible with UHMW-PE frontal panels and steel frames
Both products were manufactured using high-quality marine-grade rubber compounds to ensure long-term performance in coastal and port environments.
Project Outcome
This project demonstrated several core strengths of our company:
- Custom engineering capability
- Willingness to invest in tooling for large projects
- Rapid technical response
- Strong quality assurance system
- Efficient international logistics coordination
The client highly recognised our professional attitude, production efficiency, and product reliability. The successful completion of this project lays a solid foundation for future cooperation in marine infrastructure development.
Applications of Rubber Fenders
Rubber fenders are critical components in marine and port engineering. They are widely used in:
- Commercial ports
- Container terminals
- Bulk cargo terminals
- Oil and gas terminals
- Naval bases
- Shipyards
- Floating docks
- Inland waterways
- Bridge piers
- Offshore platforms
Their primary function is to absorb kinetic energy during vessel berthing, reduce reaction force, and protect both quay structures and vessels from damage.
