International consultancy RPS has completed the acquisition of Oslo-based OEC Consulting, following approval from the Norwegian Competition Authority. The total consideration paid at the close of the transaction was £20m, out of a maximum payable consideration of £31.5m. OEC operates in the infrastructure market, as well as the North Sea oil and gas industry and the health care sector. Alan Hearne, Chief Executive of RPS, said when the acquisition was proposed last month: "RPS sees a significant long term opportunity to expand both its Energy and BNE businesses in Scandinavia. As we have successfully done in the past when establishing our presence in a new market, we have identified a high quality business capable of providing a platform for both organic and acquisitive growth. "OEC's experience and reputation in the oil and gas, renewables and infrastructure markets will be of great value to us."NR
