Task Groups

Important topics concerning the HDD industry are dealt with in the association in task groups set up especially for this purpose. The members of the task groups are primarily from the European DCA member companies. Depending on the task, external people are also invited to the meetings.

Past topics have included:

  • HDD and subsoil
  • Bending radii in HDD
  • Shaping Recommendation of Technical and Legal Contract Conditions
  • Modal bill of quantities for HDD measures
  • VOB – DIN 18324
  • Safety on construction sites
  • Tolerances for the execution of horizontal drilling works
  • Disposal of cuttings and drilling mud from horizontal directional drillings

The results of the above-mentioned work have primarily been incorporated into the “DCA Technical GuidelinesInformation and Recommendations for Planning, Construction and Documentation of HDD Projects”.

Since 2019, the DCA has also published the results of the task groups in German and English under the series “DCA Technical Information”. These are available to external parties via an order form. For members, the receipt of the Technical Information is included in the membership fee.

The task groups established by resolution of the members’ meeting rely primarily on the cooperation and expertise of DCA member companies.

Current task groups

! Status: completed Note: The following descriptions in the task group refer to the national German legal area. The task group has not yet worked on international transferability, but this is planned.

In its decree of 14 July 2015 (supplemented on 29 August 2016) the Lower Saxony Ministry for the Environment, Energy and Climate Protection (NMU) expressly clarified with regard to the topic of “disposal of drill cuttings and drilling fluid from horizontal boreholes” that drill cuttings and drilling mud are wastes subject to the „Kreislaufwirtschaftsgesetz“.

Other federal states, such as Baden-Württemberg, have meanwhile followed this interpretation. Drill cuttings and drilling mud are hence to be recovered and disposed properly and safely as mineral waste. According to the current legal interpretation, the recycling of drill cuttings and drilling mud from horizontal directional drillings on agricultural land, on agricultural land,as is done in many places and projects, is only possible under certain conditions (the decree from Baden-Württemberg even categorically excludes this).

It should be noted that the Lower Saxony decree does not cite any new legal bases, but only reiterates and clarifies the current legal situation…

A summary of the results of the task group is available in the members’ area.

Interested in the final report?

The final report of Task Group 1 was published in November 2019 as DCA Technical Information No. 4. The publication is free of charge for members. External interested parties can order the information for a fee.

Task group 2 “Coating quality” was set up due to recurring discussions on the detection of coating defects in steel pipes after insertion into a horizontal bore hole.

Objectives:

The task group will first analyse the current situation with regard to the coating materials used in connection with HDD technology, test methods and related regulations.

In addition, measures/recommendations for action will be developed which, on the one hand, ensure the quality of the coatings in the sense of the client and, on the other hand, help the horizontal drilling companies to identify and point out sources of error and risks before taking over the pipe string (often provided by the client or third parties).

Members of the task group:

  • Stephan Birtner, Westnetz GmbH
  • Francois Gandard, Optimum
  • Hans-Jürgen Kocks, Mannesmann Line Pipe GmbH
  • Dr. Thomas Löffler, DENSO GmbH
  • Wolf Schrader, TDC International AG
  • Jorn Stoelinga, LMR Drilling GmbH
  • Stefan Wittke, TDC International AG
  • Marco Warkotz-Gruber, BKP Berolina Polyester GmbH & Co. KG

In 2015, the Association published the 4th edition of the DCA Technical Guidelines entitled “Information and Recommendations for Planning, Construction and Documentation of HDD Projects”. In the course of the regular review of the contents by the Board, there is a need for adaptation in various areas. This will be implemented within the framework of Task Group 3 “Revision of the Technical Guidelines”.

The majority of HDD rig manufacturers, especially for smaller drilling rigs, now equip their rigs with automation that has extensive data acquisition and storage capabilities. The operators of these rigs are showing increasing interest in processing this data for various purposes. These can be, for example, error analyses, performance reports or even quality controls. In addition, in some non-European countries, clients are already demanding the recording of operating data, as is already practised in Germany for pipe jacking procedures with larger nominal diameters.

It is in the interest of the users (operators and also clients) to standardise the recording and transmission of data in order to be able to process this data in a uniform manner.

Objectives:

Task group 4 “Digitisation” will prepare a draft guideline on the collection, transmission and storage of machine data, which will allow an effective exchange of data between different types of equipment and the customers’ applications.

The following aspects are to be covered:

  • Review of common automation systems as well as recorded machine data
  • Definition of relevant machine data for exchange (e.g. torques, advance rates, rpm) including their respective units (e.g. SI-Units) or conversion factors
  • Compilation of further information to be recorded, possibly operator input (e.g. status, shift, operator)
  • Definition of reasonable recording frequencies depending on machine status or recording of min/max values for longer intervals.
  • Specification of possible data transmission for offline (e.g. USB stick, CSV) or online (IP based, OPC) operation including file formats and protocols, preferably based on “open” standards to allow data exchange by standardized hard- and software interfaces, independent of machine make.
  • If required, rules or recommendations for visualization or filtering of data during (post) processing
