For the development of a newly discovered oil field in the North Sea, Statoil Norway required a new pipeline for the transportation of crude oil. This involved a complex Horizontal Directional Drilling (HDD) of 800 meters of length, ranging from ground level until minus 315 meters water depth. The project has been awarded to Visser & Smit Hanab.

Van Heck designed a custom made solution

For the pilot hole a bentonite mix has been used. For the clearing and cleaning of the hole during the next 3 phases, water was required from the sea. To flush the drilling arisings through the bore, Van Heck designed a custom made solution and delivered two electrical driven AFP 600 feeder pumps and 4 electrical split case pumps EPP200, which functioned as booster pumps. The quantity and pressure of the water was controlled near the drilling rig over a distance of 450 meter.
