BP has outsourced its voice and data communications infrastructure to T-Systems in a deal that will also see the supplier manage the oil company's voice and data suppliers.
The deal, which is worth millions of pounds over five years, is an attempt by BP to reduce the cost and complexity of its comms infrastructure.
T-Systems, which is part of Deutsche Telekom, will supply voice and data communications equipment and manage BP's multi-sourcing strategy for comms services.
T-Systems will take charge of BP's global telecoms, Lans, Wans and internet services.
Dana Deasy, CIO at BP Group, said, "This will give BP a significant opportunity to reduce complexity and lower our overall cost base."
T-Systems is no stranger to working with large organisations. It already provides Shell and Centrica with datacentre and IT infrastructure services respectively.
The supplier also manages multi-sourcing contracts for Aldi, Bosch, Lufthansa and Heineken.
"As well as the technology integrator role, there is a drive for transforming the environment," said T-Systems UK managing director Sam Kingston.
He added that T-Systems will reduce the number of suppliers that BP works with.
Robert Morgan, director at consultancy Hamilton Bailey, said having a main supplier managing multi-sourcing strategies is the way the market is moving.
"It makes a lot of sence as long as the service integrator knows what it is doing. T-Systems is part of Deutshce Telekom, so I think it fits the bill," he said.
