The contractor trusted
with trunk oil pipelines
Pipeline Construction Group LLP was founded in Atyrau in 2007. We specialise in architectural, urban planning and construction work, including in-field and trunk oil and gas pipeline networks.
Over 19 years we have delivered work at Kashagan, on the Uzen–Atyrau–Samara oil pipeline, on the CPC Tengiz–Novorossiysk trunk line and at Embamunaigas tank farms — as a contractor to Caspian Pipeline Consortium-K JSC, Stroytransgaz JSC, Montazhspetsstroy JSC and Mekhstroyservis JSC.
We work across the full cycle: engineering preparation and method statements, material supply, earthworks, welding and installation, insulation and corrosion protection, hydrotesting and inspection, land reclamation and handover to the client.
