Pipeline Engineering
Integrated Solutions for Hydrocarbon Transport
EDOPEC provides full-scope Engineering, Procurement, and Construction (EPC) services for onshore hydrocarbon pipeline projects. Our multidisciplinary expertise spans the entire project lifecycle—from feasibility studies and Front-End Engineering Design (FEED) to detailed engineering, procurement, construction support, and commissioning.
We design pipeline systems for the safe and efficient transportation of crude oil, natural gas, and refined petroleum products, ensuring operational reliability and full compliance with international standards such as ASME B31.4, ASME B31.8, API, and NACE.
Our proven experience includes major national infrastructure projects, including the BATMAN–DÖRTYOL 18” Crude Oil Pipeline modernization and detailed engineering works for BOTAŞ, as well as pipeline systems designed for clients such as OPET and TPPD.
