Great interest in the “HDD Technology” members’ forum

Topic “Accuracies in HDD Drilling”

On 03.05.2023 the members of the DCA met for the 4th time for the forum “HDD technology” in Aachen. Only in 2018 the opening event of the forum took place in Essen at Open Grid. Also the “Get together” on invitation of the DCA on the eve of the forum in the restaurant Elisenbrunnen in the heart of the imperial city was very well received and used by many for an exchange of experiences. A successful start to the event.

In recent years, the forum has featured a wide variety of topics such as “HDD trouble shooting”, “requirements for small bore technology”, “new trenchless techniques in the HDD environment” and “use of downhole tools”. The annual members’ forum is primarily aimed at decision-makers, project and site managers, technical supervisors as well as planners and clients of DCA member companies, but is also open to foremen and equipment operators trained in accordance with GW 329 from the HDD drilling technology. Participation is free of charge and reserved for DCA member companies.

During the all-day forum, which was very well attended this year with more than 50 participants, the members of the association were able to inform themselves about the topic “Accuracies in HDD drilling” and join in the discussion. Once again, numerous member companies were involved in the preparations leading up to the event.

The 4th DCA Member Forum, which took place in Aachen at the beginning of May 2022 under the topic “Use of tools in the borehole”, had a new record participation of about 50 participants from different countries. For the first time the forum which was designed exclusively for DCA members, was held in two linguistically separate groups, analogous to the workshops at the annual congress.

Under the direction of the two moderators President Jorn Stoelinga (English-speaking group) and board member Jörg Himmerich (German-speaking group) a total of five one-hour blocks were filled with interesting presentations and discussions: The overarching theme was “the use of tools in the borehole,” with the first block serving to explain how tools work in general: How is a drill head controlled, how do the different reamers actually work, and why do different ground conditions require different tools. The following four other topic blocks explained in more detail the different soil conditions and their specific tools.

The 3rd DCA Member Forum, which took place in Aachen under the theme “New trenchless techniques linked to HDD technology” at the end of January 2020, was well attended with 23 participants. 10 regular and 13 associate member companies, including clients from both gas pipeline construction and cable laying, took part.

At the annual congress in Krakow in October 2019, the DCA had held a workshop on the topic of “New trenchless techniques linked to HDD technology”, in which intensive discussions were held with the participants on the areas of application of the other laying methods as well as on the advantages and disadvantages compared to the classic HDD technology.

In addition to the above mentioned points, the application limits and the costs of the individual methods were also discussed. The methods compete with HDD in the field of large and small drilling technology and complement the classical construction method.

The first members‘ forum on HDD technology took place on 18th January 2018 in Essen at the invitation of DCA member Open Grid Europe. Under the motto “HDD Trouble-Shooting”, the DCA has set itself the goal of establishing a kind of “error culture” within the membership.

The HDD drilling companies in the DCA are well aware of the unplanned and undesirable incidents that can complicate the work or cause additional work in practice during drilling. In order to increase the quality and reliability of the HDD process as a whole, these experiences should be used more and more in the volume.
