Aberdeenshire-based gas turbine firm Alba Power has been bought by Swiss engineering giant Sulzer.
Alba employs 80 people between its main base at Netherley near Stonehaven as well as sites in Houston and Canada.
Each member of staff will transfer to Sulzer although the value of the acquisition has not been disclosed.
The firm last month posted its full year accounts for 2018, with turnover of £34million and pre-tax profits of £7.5million.
General manager Neil Mackenzie said “continual growth” is expected in 2019.
Around a quarter of Alba’s business comes from the oil and gas industry.
Sulzer said the acquisition will diversify its gas turbine service business into offshore and marine applications.
Meanwhile Alba described the deal as the “next chapter” for the Aberdeenshire firm, which incorporated in 2003, including the “geographic and technical” opportunities afforded by it.
Daniel Bischofberger, president of Sulzer’s Rotating Equipment Services, said: “Alba Power strongly complements our existing service offering in gas turbines globally, diversifying our gas turbine service portfolio both into smaller gas turbines and distributed power.
“Alba will benefit from our global sales and service center footprint and technical expertise required for servicing heavy industrial gas turbines.
“They have an outstanding reputation with their customers and we are very happy to welcome them to the Sulzer team.”
