Knowing the geological structure beneath the seabed is very important, especially for anything that is built or laid on the seafloor.
The data is helpful when building structures on the seabed such as offshore energy devices (wind, tide and wave), bridges and tunnels. The maps help to select the best site for the structure. Understanding the nature of the seabed (strength and type of sediment) will help prevent any disasters or long term problems with a structure. This can be done by avoiding unsuitable seabed or engineering a project to suit the type of seabed it is to be built on.
The data is useful for laying cables and pipelines on the seabed. They help find the best route to lay them and help spot any hazards like shipwrecks. |
