HDD-drilling for grid connection „HelWin 1“
By spring 2013 the completion of a strong grid connection of 576 MW for Off-shore wind power parks is planned to install in the North Sea, near the isle Helgoland. The project includes the construction of the 130 km long high tension direct current connection that starts at the conversion platform on sea and runs to the distribution station in Büttel. On its way from the Sea to land, the cable trays cross the coast line, which is marked by the land protection dyke a national park Schleswig-Holsteins tide lands.
Gas pipeline passes below the river Elbe
It is the longest horizontal drilling of the occidental world. However, the car driver, driving on the B5, who only rushes by, a few meters from the construction site, will hardly notice that. Only a few containers, a drill rod carriage, a few mixing vessels, a digger – much more is not to be seen. Even at a closer glance, you cannot believe, that at this place a steel pipe line of diameter 140 cm shall appear out of the grayish muddy ground on 10th November. Completely pulled through, below the river Elbe, with help of a prepared drill hole of, anyhow, 1,80 m diameter.

Horizontal directional drilling technique used für pipe-by-pipe pulling-in of DN 900 ductile iron pipes in Belgium.
Constantly spreading built-up areas, wide multi-lane roads or complicated routes are making it increasingly difficult and expensive to replace existing pipeline-systems, or lay new ones, by the open trench technique. This is why trenchless installation techniques have been under development an in use for some 30 years now.

1,200 m of district heating pipeline in three weeks
In the North Rhine-Westphalian town of Hamm, the successful connection of the district heating went almost unnoticed: HDD drilling technology was applied to facilitate a crossing below the Dattel-Hamm canal and the River Lippe. In order to be able to supply several hundred households with district heat, 3 tunnels were drilled with respective lengths of 420 metres.
