Services of outfalls

& intakes

For many years BTT Marine has been associated with marine outfalls and seawater intake installations.

Wide appreciation of the design aspects together with a comprehensive range of installation techniques gives us the special ability to put the optimum package together. We have the experience and expertise to controlling, construct and install outfalls and intake pipelines manufactured from steel, concrete or plastic and the know-how to engineer the methods accordingly.

Traditionally outfall and intake pipelines have been installed directly into pre-dredged trenches. Alternative methods of post-lay trenching or jetting techniques can be adopted using trenching machines.

Operating internationally, we strive to develop high quality technical solutions using the most effective and appropriate installation techniques available
