HORIZONTAL DRILLING INTERNATIONAL (HDI)

摘要

HDI, is - since 1984 - a specialised crossing contractor, operating 11 horizontal directional drilling (HDD) spreads with capability up to 400 t of pulling force. With its integrated engineering capabilities, the drilling methods developed by HDI have proven themselves in the most difficult of circumstances, such as shore approaches, mountain crossings, and large diameter and long distance pipeline crossings, while respecting the strictest environmental considerations.
