Foundation and reinforcement workunder water with Wassara-hammers
In maritime projects, like drilling in harbours, the Wassara-technology and hammers offers superior efficiency compared to conventional drilling methods. The capacity is falling quickly when drilling with air-powered DTH hammer.
With a Wassara-hammer, the capacity and speed is maintained during the whole operation, the surrounding water does not affect the drilling.
No oil in the water
Another benefit with the Wassara-hammer is that it uses no oil, which eliminates the risk of any oil polluting the water. This is often a strict requirement when drilling in maritime areas.
Minimised risk of pressurising the formation
The likelihood of pressurising the formation is very low when using a Wassara-hammer. This is always a risk when drilling with air-powered DTH equipment.
Cracks and cavities in the formation will be at risk of expanding drastically with the expanding air.
