Presentation

D C L

Digital Connection Co. Ltd. (DCL) was created in 2002 by Mr. Abdullah Akbar Natheer, a Saudi Aramco retiree, who had spent his career in Outside Plant Construction (OSP).

DCL undertook short form contracts in the beginning in the field of Telecommunication OSP.

During the first long form contract awarded by Saudi Aramco (Microwave Replacement, BI 10-3988), DCL introduced the idea of converting all road and utility crossings from open cut method to Horizontal Directional Drilling (HDD). The proposal was implemented and execution time was reduced to 1/3 of the scheduled duration planned for the construction of road crossings.

This was the start of a journey which has evolved into creation of the most comprehensive Trenchless Technology service provider in Saudi Arabia.

ACHIEVEMENTS

DCL has completed more than 100,000 meters of utility crossings using various trenchless technologies, HDD, micro tunneling and pipe ramming.

DCL has constructed pipeline crossings up to 48 inch dia pipes using HDD.

DCL is credited with construction of world’s longest in length (3,045 meters) and largest in pipe dia (30 inch) crossing using HDD, at the time of execution back in 2008.

DCL has the most successful record of construction of pipeline crossings under the sand dunes in Shaybah.

Digital Connection Co. Ltd.Pi lot Hole Dri l l ing

A PILOT HOLE is a smaller hole drilled into a material prior to a larger hole being drilled

The REAMING operation consists of using an appropriate tool to open the pilothole to a slightly larger diameter

The PULLBACK operation involves pulling the entire pipeline length in one segment(usually) back through the drilling mud along the reamed-hole pathway.
