As part of its commitment to climate-resilient and future-ready infrastructure, Fiji Ports Corporation Limited (FPCL) has delivered a transformative Wharf Rehabilitation Project at the Port of Lautoka, featuring the use of GreenTech Shield (GTS)—a next-generation Electrochemical Chloride Extraction (ECE) technology.
GTS offers a high-performance, environmentally responsible alternative to traditional galvanic anode systems. While conventional systems provide localized, passive protection, GTS actively removes embedded chlorides from all exposed concrete surfaces, halting steel reinforcement corrosion at its source. This extends the asset’s structural lifespan and minimizes the need for repeat interventions.
Deployed from September 2023 to May 2025, the system consistently exceeded benchmarks set under NACE SP0107-2021. In several applications, chloride levels were reduced well below the critical 0.4% weight-of-cement threshold prior to reaching energy input limits, confirming both efficiency and effectiveness.
Crucially, GTS contributes to indirect carbon footprint reduction by reducing the frequency of structural repairs and the associated demand for high-emission construction materials like cement and steel. It requires no ongoing power supply or complex monitoring, making it a low-impact, high-return solution that reduces lifecycle emissions, material waste, and operational downtime.
The project was executed with zero disruption to port operations and under strict environmental safeguards, strengthening Queen’s Wharf—a vital asset for both cargo and passenger transport. Aligned with the Green Port Master Plan (2019–2025), this initiative exemplifies how advanced materials technology can drive sustainability in port infrastructure. It supports Fiji’s national goals for green infrastructure, climate risk reduction, and low-carbon development, while offering a scalable model for other Small Island Developing States navigating similar challenges.
