Successful Delivery: Jetty Pile Supply & Installation for a Small National Port

Project Background

Location, Scale, and Client Requirements

This Jetty Pile project was carried out for a small national port undergoing phased capacity expansion. Due to increasing cargo throughput and aging waterfront infrastructure, the client required a new jetty structure capable of supporting higher operational loads and improving berthing efficiency. The engineering consultant specified tubular piles with high structural strength, strict dimensional accuracy, and enhanced durability in a marine environment.

Our Scope of Work

Tubular was contracted to provide a full chain of services, including material procurement, fabrication, anti-corrosion coating, transportation, and on-site installation support. The key supply included Ø1200 mm tubular piles with a 25 mm wall thickness, totaling 300 piles, along with customized pile shoes and lifting lugs. Our team also coordinated sea freight, port discharge, temporary storage, and installation assistance during the jetty construction phase.

Key Technical Features & Service Highlights

Special Fabrication Requirements

Marine foundation works demanded exceptional manufacturing precision. The supplied Jetty Piles featuredthick-wall sections, large diameters, and heavy-duty corrosion protection systems suitable for seawater exposure. Automated welding, ultrasonic testing, and full-length dimensional inspections were conducted to ensure structural reliability. All piles passed factory acceptance tests before dispatch.

Optimized Logistics Arrangement

To meet the client's construction timeline, Tubular designed a dedicated logistics plan covering consolidated sea shipment, coordinated port unloading, and short-term yard storage. Through close coordination with the shipping line and port operators, the piles reached the project site smoothly. Remarkably, the entire process—from final factory inspection to port discharge—was completed in just 45 days, helping the contractor start installation ahead of schedule.

On-Site Technical Support

Our engineers supported the contractor throughout the lifting, positioning, and driving process. This included elevation checks, pile alignment verification, and installation records for third-party inspection. Upon completion, independent measurement reported that the pile head deviation remained within ±20 mm, significantly outperforming the contractual requirement of ±50 mm.

Challenges and Solutions

Tidal and Wave Impacts During Installation

Due to variable tide levels and seasonal wave conditions, driving accuracy was a major concern. To address this, real-time survey monitoring and segmented installation planning were applied. The contractor adjusted working windows to avoid peak tidal movement, ensuring stable installation and minimal deviation.

Tight Delivery Schedule and Component Shortages

The project required fast-track delivery. When auxiliary components faced potential delays, Tubular activated alternative suppliers and reorganized internal production priority to secure timely completion. This proactive coordination allowed all materials to arrive without impacting the installation sequence.

Project Outcomes and Client Feedback

Outstanding Delivery Results

The project achieved multiple performance targets:

• Early delivery, enabling earlier-than-planned jetty construction

• Cost optimization through consolidated shipment

• Full compliance with quality and dimensional specifications

• Smooth third-party acceptance of all installed piles

Client Testimonials

The client highly recognized Tubular’s efficiency and professionalism, stating:
“Tubular’s one-stop service saved us from coordinating multiple suppliers. Their logistics planning and installation support truly demonstrated real engineering delivery capability.”

Key Lessons and Recommendations

Advice for Similar Port or Jetty Projects

Early planning of pile specifications, coating systems, and logistics is essential for marine infrastructure projects. Consolidated procurement and shipment not only reduce cost but also avoid delays caused by fragmented supply chains.

Value of Early Involvement in the Design Stage

By engaging suppliers earlier in the engineering phase, owners can optimize pile dimensions, coating selection, and welding design—significantly improving constructability and reducing overall project cost.
