STATS Group has appointed two new directors as part of a strategy to double the size of the business. Carl-Petter Halvorsen has joined the pipeline engineering company as business development director while Dave Shand takes up the newly created post of chief operating officer. The dual appointments will strengthen STATS’ management team and free up chief executive officer Pete Duguid to focus on international development of the company’s unique range of piping and isolation tools for the oil and gas industries.
