Alotau Provincial Wharf Piling Project

Project Overview

Located in Papua New Guinea, the Alotau Provincial Wharf Piling Project involved the supply of 686 tons of high-grade LSAW steel pipes in compliance with AS1163 / AS3678 GR350 standards.

The project featured two key specifications designed for marine piling in challenging environmental conditions:

711×16 mm, lengths 8,000–11,250 mm

610×20 mm, lengths 7,000–11,167 mm

Project Execution & Adaptive Solution

Initially planned as full-length piles (34–52 meters) with anti-corrosion treatment, the project encountered logistical challenges due to uncertain shipping schedules. Through close collaboration with the client, we proposed and implemented an optimized solution:

Shorter pipe segments (under 12 meters) for ease of transport

Factory-based butt-welding and anti-corrosion treatment in Australia

Final delivery via barge to the construction site in Papua New Guinea

This flexible approach ensured project continuity while maintaining full compliance with technical specifications.

Quality Assurance & Certification

Comprehensive third-party supervision by TÜV, covering materials, production, finished products, and packaging

Full oversight of relevant testing procedures

100% pass rate on all required tests

Batch shipments successfully delivered to Australia for subsequent processing

Project Outcome

By integrating engineering expertise with logistical adaptability and stringent quality control, we contributed to the successful development of vital port infrastructure. This project demonstrates our ability to deliver tailored, compliant, and high-assurance solutions for complex international engineering projects.
