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.
