Horizontal directional drilling (HDD)
Pipeline and cable routes often cross existing underground infrastructure. Therefore Nacap replaced the conventional aboveground installation methods with a range of underground technologies that avoid the need to dig trenches. The nuisance is limited in every project and the impact on the environment is as small as possible. Worldwide, Nacap has more than 8 drilling plants with a capacity ranging from 60 to 400 Te, which enable Nacap to meet all the clients' requirements. All over the world, Nacap has carried out horizontal directional drillings in all sorts of soil types - for cables and pipes with diameters up to 1200mm (48") and for lengths of more than 2000meters.

HDD record underneath the Ketelmeer
Nacap successfully finished a HDD record in the night from the 6th of July
In December 2009, Nacap was awarded the contract for the construction of a natural gaspipeline from Swifterband to Emmeloord in the Netherlands. This new pipeline crosses the Ketelmeer: a lake of 3500 hectares. Part of this project is a record HDD with a length of 2.800 meters. After initial problems, the pipeline was successfully pulled in, in the night from the 6th of July. The drill was executed according to the ‘meeting in the middle' principle. At both sides of the lake, rigs where placed and the drills met under the lake, a great accomplishment.
