Dutch network operator TenneT uses Prime Drilling rigs


To secure energy supply to about 80 million customers in Germany a more than 35,000 km long high-voltage network transfers energy from the electricity producers to the end users. One of the four supraregional network operators in Germany is the Dutch company TenneT. Within the project "Ranstad 380 kV" in the Western part of the Netherlands the company, as the first network operator in Europe, has successfully installed an about 11 km long 380kV cable into the soil. Part of the line, which passes underneath obstacles such as buildings, motorways, rivers and railways, was realised by means of computer-controlled drilling operations. For these difficult and precise works the company used Horizontal Directional Drilling Rigs made by Prime Drilling.

German Technology and Oriental Flair


In the Central Asian state of Uzbekistan, near the industrial city of Nukus, the crossing of the country´s longest river has been successfully realised.  Thanks to the PRIME DRILLING Horizontal Directional Drilling Rig type PD 250/90 RP designed as trailer version and the team of experts on site the installation works were completed quickly and easily. Over a length of 1,000 meters the steel product pipe of diameter 1.042 mm was pulled in under the Armudaja river. The top-quality drilling rig had to withstand the most difficult conditions prevailing in the Uzbek steppe region such as frequent desert storms and extreme temperatures. In the fine sandy, demanding soil the drilling rig impressively proved its exceptional performance. After only three weeks from start of the project the successful completion of the pipe installation was reported to the highly pleased client company, Neftegazmontajz.

Successful premiere of "system 2" with
Prime Pipe Pusher


The first field operation of the revolutionary "system 2" was successfully realised during the relocation of the gas pipeline Moscow - St. Petersburg. Owing to the combined application of the Prime Pipe Pusher PPP 400 manufactured by Prime Drilling together with a tunnel boring system the Russian company PodzemBurStroj was able to meet the specific requirements of the project. In only one work step the bore hole under the Moskva channel was drilled and the pre-bent and pre-fabricated pipeline was installed. With this innovative pipe installation method future crossings within pipeline projects can easily be achieved with high positional accuracy, even under limited space conditions and with large-diameter steel pipes.

Prime Drilling involved in record drilling project


The longest horizontal directional drilling in the history of HDD technology has been realized successfully in the USA by means of a Prime Drilling Rig type PD 500/120 RP-F. Being part of the 224 km gas pipeline leading from Liberty (Texas) to Eunice (Louisiana) the 3,373 m long HDD project was completed within very short time. Last summer the drilling rigs started the pilot bore from two opposite points under the river Sabine and, at the first try and within only 12 days, the two drillings met accurately at the previously calculated point without any complications.

Boring genius

... “It is all custom made,” says international sales and service director Ralf Kiesow. “Everyone wants their design to be a little bit different and this is where we are really strong. Prime Drilling has an in-house design team that takes care of exactly what the customer requires and can even recommend designs that are more suitable where necessary. In terms of recent contracts, we sold two machines to Australia that will be used for coal seam gas drilling that were specially designed for the client. We are also about to build a machine for Nigeria that is able to sail natively. It is a drilling rig that doesn’t need a separate barge to work in swamps because it can float and maneuver itself. It’s the first one we’ve made and I believe possibly the first one in the world.”...

PRIME DRILLING HDD-Drilling Rigs for Gas Drainage Drillings of Coal Seams in Australia


... In New South Wales and Queensland exist large near- surface deposits of high- quality hard coal, which are to be extracted by open-cast mining. With mining of these coal deposits a gas based on methane is produced called coal seam gas, which is known as “mine gas “ in Europe and which is similar to natural gas in composition. Coal seam gas is produced by the decomposition of organic components within coal deposits. In the past this gas was simply burnt, but these last 10 years it has been used more and more often to generate electricity. To be able to extract the gas, the water in the coal seam has to be pumped out first to lower the pressure inside and thus to allow for extraction of the gas. ...

Gas pipeline passes below the river Elbe


No Dig DagIt 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 pipe 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.
