The Greatest Climate Change Challenges Dredging Companies Face

The Greatest Climate Change Challenges Dredging Companies Face

The reality is that the earth’s climate is changing in ways we don’t yet fully realize. With these changes come new logistical issues for dredging companies who have to adapt to an evolving environment.

The issue of climate change is on the mind of every dredger, and these challenges, in particular, are ones they will have to react to sooner rather than later. Here are a few climate change challenges dredging companies face:

  1. Port And Harbor Issues
  2. Larger Floods
  3. Environmental Adjustment

New call-to-action

1- Port And Harbor Issues

Ports and harbors are easily the world’s busiest pieces of maritime infrastructure. Shipping containers disgorge tons of cargo and goods at ports and harbors every day. Despite the high volume of use, these areas are susceptible to changing sea levels. This is due, in part, to the proposed lifespan of an individual port or harbor, which is typically about 40-50 years before it needs to be rebuilt, or expanded, excluding regular dredging work to remove built-up sediments.

Many existing ports and harbors were built without concern for rising water levels and may face the issue of flooding or being washed away. Dredgers will play an increasingly important role in the maintenance of these infrastructural pieces.

That’s because dredging equipment will be needed to address a variety of water management issues. The ports and harbors will need to be made deeper by dredgers. Similarly, drainage areas will need to be expanded and reinforced due to the increased frequency of heavy storms.

Finally, taller, and more robust storm walls will need to be erected to manage the waters within the port. While dredging companies already carry out many of these tasks, the frequency by which they will need to be done raises concerns about whether the number of trained operators and machines that are at each company’s disposal can meet this demand.

2- Larger Floods

Flooding, in particular, has been one of the more dramatic examples of global climate change. For instance, Houston, Texas was the victim of terrible flooding after Hurricane Harvey. Dredges will be utilized to create new drainage ditches, sculpt pathways for the water to flow through, and to increase the size of retention ponds and reservoirs to ensure that these spaces do not overflow.

The difficulty in these tasks, of course, is in predicting just how much larger these pieces need to be. While earlier generations could make fair assumptions about annual rainfall, and build drainage infrastructure according, in a period of dramatic changes, it grows increasingly more difficult to offer accurate estimates.

Dredging companies then may expand a retention pond once, only to have to expand it again a few short years later in response to severe, and regular flooding.

3- Environmental Adjustment

Finally, dredging companies need to be aware of changing environmental conditions. Given the fact that dredgers work directly with marine ecology, they need to be experts in dealing with rising sea levels and other environmental shifts. Dredgers may have to adjust their machinery for deeper depths or new challenging terrains.

They will also have to find ways to protect and preserve the delicate ecosystems they may come across. This means coming up with ways of minimizing pollution, reducing dredging timeframes, or finding alternative resources for operation — all of which come at an added cost.

 

To sum it up, climate change brings with it a number of serious logistical issues that dredging companies need to address. The challenges are varied, from port and harbor issues, to large floods, to environmental adjustments. Dredging companies will have to make significant investments in their machinery, their personnel, and other resources if they want to remain a viable option for maritime maintenance in the face of climate change.

Always Searching For Innovative Solutions

Despite the seemingly enormous task ahead of them, leaders in the dredging industry are preparing to tackle the challenges of climate change head-on by creating new machinery and finding ingenious ways to use the environment itself to assist their projects.
