We apply DIN EN 13480, DIN EN 13445, ASME B31.1, B31.3, B31.4, B31.8, PED 2014/68/EU, ASCE 7-22, API and other international standards, as well as corporate standards of UOP, Shell, Sinopec, Tecnimont, Saipem, Linde, Schlumberger, McDermott, Daelim, Samsung and others.

ENECA focuses exclusively on design/planning and does not engage in equipment sales. ENECA has extensive experience in developing solutions using equipment from major manufacturers, including Siemens, Caterpillar, Hitachi, Howden, Buderus, Viessmann, Kablitz, Capstone, Champion, Atlas Copco, Omega Air, Mikropor, Lupamat, Airpol, Ingersoll Rand, Jenbacher, Stribo, MWM, A1R, Baosi, CS Instruments, MTU, and Entroros. This expertise allows us to provide professional guidance and comparative analysis to help select the most suitable technology and develop efficient process solutions with maximum speed and effectiveness.

With offices in Kazakhstan and Uzbekistan, ENECA performs review and acceptance of basic engineering packages and licensed process documentation (PDP, FEED, DED stages) from process developers and licensors — including UOP, Shell, Sinopec and others — and verifies compliance with local codes and standards across Piping and Equipment disciplines. We also have hands-on experience reviewing PDP and FEED packages developed by Chinese licensors.

We offer comprehensive solutions to a wide range of problems, from initial pre-project analysis and equipment selection to detailed design. Our team is committed to ensuring that design decisions are implemented to the highest quality, resulting in a successful and efficient project outcome. 

We are capable to deliver fully multidisciplinary design — covering process & piping, structural, electrical, and automation disciplines under one roof. Engineering models are developed in AVEVA E3D and other platforms, with every element enriched with attribute data. This enables seamless multidisciplinary collaboration, automated drawing and specification generation, and continuous project control — minimizing clashes and reducing costs across both design and construction phases.

Safety is integral to our engineering process. We have extensive experience designing systems in high fire and explosion risk environments, as well as facilities handling flammable and chemically hazardous materials — including phenol-formaldehyde resins, diesel fuel, and industrial oils. Key priorities across all projects include equipment reliability, rigorous quality control, comprehensive process automation, and safe process management.
