The company said: “This new acquisition will strengthen Murphy’s existing presence in the sector by bringing significant design, engineering, commissioning, operations and maintenance expertise to its water sector offering, notably in Ireland.
“These skills mean Murphy will be in a strong position as it expands further into complex and integrated work, in particular as clients in both the UK and Ireland set out their future investment plans.”
Steve Hollingshead, chief executive officer at Murphy, added: “This is an exciting acquisition for Murphy and one that really adds to our skills and experience in the market.
“It will build on our current offering, and really improve the value and service we can give to our clients and their customers.
“It is also another positive step forward in our ambitious business plan to grow and develop Murphy over the next decade.”
