Members‘ Forum

Since January 2018, the DCA has been offering a new event, the so-called DCA Member Forum HDD Technology.The forum offers a platform for members of the association to exchange experiences and is primarily aimed at site managers and maschine operators, but is also open to interested technical supervisors, planners and clients as well as interested parties from the supplier industry. Participation in the forum is free of charge and exclusively reserved for members. From 2021, it is planned to hold the event parallel in two linguistically separate rooms (German-speaking/English-speaking groups).

The following member forums have already been held:

The Members‘ Forum 2021 HDD-Technology will take place in Aachen for the third time.After the kick-off event at the beginning of 2018 at DCA member Open Grid-Europe in Essen on the subject of “HDD-Trouble Shooting”, this time the association will focus on the subject of “subsoil investigations”. This year the HDD workshop will take place in two linguistically separate groups for the first time.

For the application of HDD technology, precise information of the subsoil on the basis of qualified soil investigations in the route area is always required in order to be able to reliably assess the feasibility of a project and reduce the subsoil risk to a minimum. In order to obtain this information, targeted soil investigations by the client are necessary.

The planning of the necessary investigations, the professional supervision of the field and laboratory work and the preparation of a geotechnical investigation report (subsoil expertise) must be carried out by a qualified subsoil expert with relevant knowledge and experience of the working methods and special features of HDD technology. The report should specifically address the specific, constructional aspects in connection with the application of the HDD technique in order to enable an assessment of the drillability of the encountered soil layers

The aim of the HDD workshop “Soil Investigations” is to firstly examine and evaluate the HDD-specific geotechnical parameters and terminology used in a soil expertise. In addition, it will be discussed which minimum requirements have to be met and which parameters are advantageous for which conditions, i.e. what significance the individual parameters have.

The workshop 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 HDD drilling equipment operators trained according to GW 329 (Germany). Participation in the event is free of charge and exclusively reserved for DCA member companies.

! Note:Due to the current Corona situation, the Board has decided to postpone the event scheduled for the end of January to a later date in 2021. The new date will be announced soon.

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.

On 05.02.2019, the second DCA Member Forum HDD Technology took place in Aachen. The event was held as part of a workshop on the topic of “Requirements for small drilling technology”. A total of 18 people took part in the members’ forum. Nine drilling companies, three planners and one client and further suppliers were present. Three participants had to cancel due to illness.

The following points were discussed:

  • Definition Small Scale Drilling
  • Requirements in the DCA-Guidelines to small scale drilling technology
  • Project classification according to degree of difficulty (see chapter 10.5.1 ff of the TR)
  • Drilling mud disposal
  • Dealing with inadequate planning on the construction site/ Dealing with unreasonable demands of the client etc.

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.
