Kyowa rock bags are a popular product for erosion prevention, used in various sites across the globe today. However, this unique product aids us in many other situations as well. Rock bags are eco-friendly, durable, and long-lasting, so they are readily used in offshore and undersea projects for purposes varying from submarine cable protection to offshore barriers construction.
Why Is It Important to Build Offshore Barriers and Protect Underwater Structures?
Protecting offshore structures like wind farms, oil platforms, gas production sites, and bridges is a matter of paramount importance. The design and construction of these structures are costly. Hence, it’s vital to sustain them for a long time.
These offshore sites are more prone to heavy winds, seismic forces, strong currents, and other factors associated with the location. In situations of damage or collapse, they can pose a threat to marine life. Therefore, the foundations of offshore barriers and sites should be strong.
It is also important to pay attention to submarine cable and pipeline protection as they usually carry gas and oil.
Damage can cause a leak, releasing these substances to the marine ecosystems, which is very harmful. It can be due to a heavy object dropped on them, an anchor dragging the cables accidentally, or a natural phenomenon like a storm.
Moreover, constant exposure to seawater leads to corrosion.
How Do Rock Bags Help?
A product as simple as rock bags can help you protect valuable marine structures. Moreover, by using them, you can,
Build offshore barriers
Tackle coastal erosion
Provide pylon protection for bridges
Protect subsea pipes and cables from subsea corrosion
Stabilize subsea pipes and cables from swaying and moving
Support the foundation of navigation towers, wind turbines, and other offshore structures
One significant offshore protection project in Australia using Kyowa rock bags was the refurbishment and upgrade of 9 Aids to Navigation (AtoNs). It was undertaken by the Pacific Marine Group for the Australian Maritime Safety Authority (AMSA).
The Kyowa filter units were used as a part of the project that spanned from the Lockhart River (Northern Great Barrier Reef region) through the LADS Passage. The renovation aimed to restore the damage caused by Cyclone Trevor in March 2019.

What Are The Features of Kyowa Rock Bags?
Here’s why rock bags are the best option for your offshore projects!
A 2-tonne rock bag offers scour and erosion protection against water velocities up to 4.7m/sec. Moreover, a 4-tonne rock bag can withstand up to 5.3m/sec.
Rapid and automated deployment. The R.O.V aided release system can drop the bags at the precise location safely. Even though in most cases is not necessary, a diver can assist with the deployment.
They are eco-friendly and support marine life. Rock bags become an ideal habitat and breeding ground for small fish over time
Use a single-point lifting system
Durable and long-lasting. They last up to 50 years in water and up to 30 years’ protection against UV rays
No foundation required for installation
Flexible
