Controlled directional drilling is the science and art of deviating a wellbore along a planned course from a starting location to a target location, both defined with a given coordinate system.
Drilling a directional dril basically involves drilling a hole from one point in space (the surface location) to another point in space (the target) in such a way that the hole can then be used for its intended purpose.
Directional Drilling, or Horizontal Directional Drilling (HDD) is a technique by which pipe, duct or cable can be installed underground without disturbing surface structures and thereby avoiding the disruption caused by traditional open trenching methods.
This process can be done under motorways, waterways, railways, airport runways and SSSI sites.
The cost savings resulting from the application of this technology, in both direct and consequential terms, can be very significant. Directional Drilling (HDD) is fast, efficient and environmentally friendly.
Using the latest in tooling and mud technology, successful installations can be achieved in most ground formations.
The use of horizontal directional drilling (HDD) has become widespread for the installation of many types of utility services including electric lines, water lines, gas lines, and fibre optic. The minimal amount of surface disruption incurred and reduced restoration required when utilizing HDD makes it a desirable solution for many installations.
Why Choose Horizontal Directional Drilling for Your Next Project?
There are many advantages to using horizontal directional drilling and it is the preferred method when a pipe has to be used near a large river or another type of sensitive crossing. However, when undertaking long distance underground pipeline work that is being built across an open area such as farmland, then a trench is dug
on an approved route and the pipeline is lowered into the trench. The soil is then replaced on top to begin the restoration process.
It is the preferred construction method in large river crossings, badly congested areas and some other unique situations and the main reason for this is because it will minimise the impact on the area that is above the drill. The land at the entry and exit points of the drill will be disturbed, however, this will then be restored once the pipeline has been fitted.
What types of HDD Battersby’s currently use
Battersby Construction & Groundworks Ltd researched the market and found that the use of a Horizontal Directional Drill could be used on specific jobs within the BT Openreach contract.
The result after looking at several different HDD on the market was to purchase two different versions.
The two HDD that Battersbys have purchased are:
