AMEC Foster Wheeler Limited, originally known as Amalgamated Mechanical Engineering and Construction (AMEC) Limited was an international consultancy, engineering and project management company responsible for numerous projects in various counties around the world. Its main focus was on the oil, gas chemical, mining, power and infrastructure sectors but it would be involved in numerous others over the course of its existence. Founded in 1982 by the merger of Leonard Fairclough & Son and William Press Group it would acquire a number of other companies throughout its existence that would allow it to operate in a number of different fields and countries. This included Foster Wheeler, which was taken over in 2014, at which point AMEC Limited changed its name to AMEC Foster Wheeler Limited. During 2016 a downturn in oil and gas revenue led to a reduction in orders from the company’s primary customers resulting in increased debts and the resignation of Samir Brikho from the Chief Executive position. The following year the company would be acquired by the Wood Group for £2.2 billion.

AMEC Engineering Limited was established in 1962 as Matthew Hall Engineering Limited. This was part of the division of Matthew Hall and Co into multiple operating companies which would then form the Matthew Hall Group. These subsidiaries were Matthew Hall Mechanical Services, Matthew Hall Engineering, Matthew Hall Works and Plant. The main focus of Matthew Hall Engineering Limited was the design and construction of oil, petroleum, petrochemical, pharmaceutical industrial and food processing plant. It would continue to do this even when it, along with the rest of the Matthew Hall Group, was acquired by AMEC PLC in 1988. In 1992 its name was changed to AMEC Engineering Limited and it began to operate on an agency basis for AMEC Process and Energy Limited. Both companies were declared dormant in 2001.
