Advantica

"Advantica is the new name for a business which has created substantial value by providing technology and engineering solutions for one of the world's most sophisticated gas networks. From our origins in British Gas, we have developed a leading position as improvers of business and operating performance for customers in the gas, pipelines, and associated industries worldwide. Our expertise ranges from oil and gas production through to managing energy use and the environment. Advantica's roots are in the research and development arm of British Gas - set up to meet the challenges of creating a safe and efficient natural gas network. Through the growth of a nationalised industry, privatisation, market liberalisation, and the subsequent split into the BG Group and Centrica, we were at the cutting edge of change in the industry. BG Technology, as the research and technology division became, built on this strong foundation, adding commercial, engineering and training skills to become a leading provider of independent services to customers both outside and inside the BG Group."
