About XDS

A self-performing engineering services partner.

Xazar Daniz Service LLC (XDS) is an Azerbaijani engineering services company providing construction, fabrication, inspection and field services to the oil & gas and industrial sectors. Since its founding in 2005, XDS has built an experienced team of engineers, technicians and skilled trades, supported by a fully equipped fabrication base in Baku and a regional service network.

The company is committed to delivering integrated engineering solutions that meet the most demanding client requirements. XDS self-performs every stage of project execution — from feasibility and detailed design through procurement, fabrication, construction and commissioning — using its own crews, workshop and in-house testing capabilities.

Combining local execution capacity with international engineering practice, XDS has supported asset operators, oilfield service majors and offshore EPC contractors for over two decades — building a reputation for engineered solutions, on-time delivery and uncompromising commitment to safety and quality.
