Scouring Protection for New Zealand Port Using Rock Bags

wharf scouring protection using rock bags

Have you heard about bow thrusters? If anything, here’s what you need to know: bow thrusters are not a hang-over from Danny and Sandys’ 1970’s disco craze. They actually serve a serious purpose. Bow thrusters are props beneath ships that improve manoeuvrability when entering or leaving ports at a lower speed. While they are highly useful for vessels, it’s not the same case for ports, making wharf scouring protection a necessity!

How Bow Thrusters Affect Wharves

The excessive turbulence caused by bow thrusters and ship propellers is a major reason for erosion at wharves.

The continuous currents directed at the shore by ships can damage revetments again and again, disrupting the foundation of the wharf. The lack of scouring protection can eventually affect the stability of the berthing structure, leading to higher renovation costs in the long run.

The Damaging Impact of Large Vessels

Port authorities indeed want to accommodate vessels of varying sizes because they are all important. However, the issue is that the magnitude of a thruster is proportionate to the size of the ship.

We know that ships have doubled in size over time, which means you need to do everything to protect the ports from massive bow thruster damage. Accommodating Ultra Large Container Vessels -ULCVs- and cruise ships can expose port assets to risk, especially if you don’t have shore erosion control measures in place.
