Whanganui Port in New Zealand is actively working on long-term dredging solutions to ensure clear waterways and improve the port’s accessibility for vessels. This strategic move aims to support both local and visiting marine activities while safeguarding the port’s operational efficiency.
Whanganui Port’s Long-Term Dredging Strategy
The port is in the process of seeking a comprehensive, long-term dredging consent that will replace the current two-year priority dredging permit granted in early 2023. This existing permit enables operators to dredge crucial areas around the port basin, including the three main wharves and the Wharf Street boat ramp.
Priority Dredging Efforts for Immediate Access and Safety
Ensuring Access Around Wharf Street and Key Port Areas
Dredging operations have already commenced at the Wharf Street slipway and the surrounding channel, aiming to optimize accessibility in preparation for the busier summer months. This strategic effort is particularly beneficial for both commercial and recreational vessels navigating the area.
Seasonal Dredging Schedule to Align with Resource Consent
Outgoing Tide Dredging Restrictions
According to the port’s resource consent, dredging activities are limited to periods of outgoing tides. “Due to limitations around our resource consent, we can only dredge during the outgoing tide,” the port shared in a recent release. “Please keep this in mind if you are planning to take advantage of Whanganui’s favorable weather for boating.”
Efficient Dredging with Modern Equipment
Using an Excavator and Barge for Effective Spoil Management
The current dredging operation is being conducted using an excavator and barge, specifically selected for efficient sediment removal. Collected materials, or spoil, are released downstream in a controlled manner, ensuring minimal disruption to the surrounding environment while maintaining navigability within the port area.
Benefits of Whanganui Port’s Dredging Operations
- Enhanced Port Accessibility: Dredging supports the safe and efficient movement of vessels, reducing the risk of grounding in shallow waters.
- Improved Safety for Boaters: By maintaining deeper channels, Whanganui Port minimizes navigation challenges for both recreational and commercial users.
- Sustainable Sediment Management: The practice of returning spoil to the downstream channel helps preserve sediment flow, contributing to ecological balance.
Future Outlook for Whanganui Port’s Dredging Plans
As Whanganui Port works toward obtaining a long-term dredging permit, operators anticipate even greater flexibility and efficiency in maintaining the port basin and channel. With a focus on sustainable practices and modern dredging technology, Whanganui Port is committed to enhancing its infrastructure to meet the needs of the local community and visiting vessels alike.
