Performance Improvements Ltd was formed in March 1997 and has become a leading independent engineering consultancy within the oil and gas industry.

The company was formed to provide multi-discipline engineering expertise to the international oil and gas industry to help maximise the uptime, efficiency and performance of existing installations. PI has experienced significant year on year growth and is now a multi-million pound enterprise.

A group structure was created in 2000 and additional start-ups were spun out, including PI Energy & Emissions Limited and PI Gas Turbines Limited. We now work with most of the leading oil and gas operators in the UK and have a growing reputation overseas for delivering significant improvements in plant uptime, throughput and emissions. PI is proud to hold ISO9001:2008 accreditation.

On the 23 January 2009 Performance Improvements Ltd became a wholly owned subsidiary of AMEC, the international engineering and project management company. Steve Wright, who remains as PI's Managing Director, said of the change, 'I am delighted that the transaction gives us the opportunity to expand our capabilities internationally, with the support of AMEC's reputation, global infrastructure and international client base. This is a good opportunity for an entrepreneurial business such as PI to achieve more of our immediate growth potential as part of a world class oil and gas services company.'

PI is commonly engaged to help improve the uptime and performance of oil and gas installations by improving process stability, debottlenecking, production optimisation and ensuring that fluids won are correctly metered and allocated in accordance with agreed commercial agreements. We are also able to help with developing and implementing maintenance strategies to ensure that Opex is optimised whilst meeting all necessary compliance issues.

PI are leaders in energy assessments having developed energy reduction protocols and carried out both site assessments and remedial work plans for sites all over the world. Products developed include the web based EnergyTracker monitoring tool. PI also works across a number of industries in the UK and overseas to improve the uptime and performance of gas compressors and gas turbines by retrofitting control systems. PI Gas Turbines also carry out total train healthcare assessments to identify and implement remedial work plans.
