Techno Global Services has executed many river crossing projects for oil & gas pipelines, some of which involve Horizontal Directional Drilling (HDD). HDD is an advanced technology useful for construction of all types of pipelines and cable lines under various terrain obstacles such as rivers, lakes, ramparts, roads, canals, swamps, runways, parks, sanctuaries, etc. The obstacle is crossed by drilling under it, from one side to the other, using special machine called drilling rig. Horizontal Directional Drilling (HDD) has seen enormous growth in the last decade as it offers a clear alternative to open trench and other trenchless construction methods. Techno Global Services has executed HDD in several of its pipeline projects, also working in conjunction with other HDD contractors with specialized equipment.
