EnerMech said it will invest a further £2m ($3.7m) to expand Norson’s hydraulic services to EnerMech bases in Dubai, Singapore, West Africa and Perth, Australia.
The total investment for Norson, including potential expansions, is expected to be about £41m ($63.15m).
The company expects the acquisition will help it earn a revenue of more than £60m ($92.42m) in 2010.
Norson Power provides hydraulic pipework installation and designs, and manufactures hydraulic equipment for the oil, gas and marine industries.
EnerMech, which provides mechanical services, hydraulics, equipment rental and training services to the offshore oil and gas sector, said Norson’s core business will complement EnerMech’s existing products and services.
