TP Group plc announced that it has been awarded a £0.9 million contract by a defence prime contractor to overhaul an atmosphere management system already fitted to an operational submarine. The contract, which commences immediately, forms part of a broader, through-life support programme that is typical for equipment which remains in service for periods in excess of 30 years. This contract is expected to be delivered during 2018 by the company's engineering teams across the UK.
