About Us

From our Engineering and Project Management offices in Ely, Cambridge, and Fabrication and Assembly facility in Swansea, South Wales, we undertake the complete design and supply of skid mounted or packaged equipment. Since 1989, OGS has supplied to satisfied clients throughout the world. We are accredited by major international operators in the oil, gas and power industries, gas turbine producers and EPC companies. Our scope of supply includes the responsibility for all stages of project execution including initial design, detailed design of process, mechanical, electrical, control and instrumentation, manufacturing, testing, packing and shipping. We also provide a site erection and commissioning service if required.

OGS has set up a manufacturing facility, Oil & Gas Systems Baltia (OGSB), in Kaliningrad (Russia), an Economic Free Zone on the Baltic coast. This factory joins our existing fabrication shop near Swansea, UK and also operates under ISO 9001:2008, thus ensuring compliance with international quality standards. Our customers include oil, gas and energy producers and international engineering and contracting companies.

OGS is renowned for delivering high quality engineered solutions for critical applications often within short delivery times. Packages are often designed for installation offshore within confined spaces and require a high level of reliability for unmanned site or offshore platform applications. Our dedication to producing an excellent engineered package is supported by an expert team focused on ensuring reliably managed delivery schedules and accurate, timely documentation.


"I am very grateful for the extremely helpful and professional way you have worked with us throughout the Project. Special attention should be given to the Project Manager who has played a central role. I am told that he has been a truly great asset throughout the project, always ready to help and solve things together with us as a team and always with a smile. Even though there has been a few setbacks, you have responded positively and quickly, and together helped solve the issue at hand."
