Interconnector, gas pipeline operator, has signed a £28m outsourcing deal with HP.
The 10-year contract involves the full range of HP products and services, including a dual data-centre service.
"Our expectation is that the improved performance will enhance our user experience and our visibility of service quality and we estimate that it will reduce IT costs significantly over alternative solutions," said Terry Stephens, chief information officer for Interconnector.
The services will be delivered from HP's data centre in Wynyard, UK with disaster recovery through Interconnector's Data Centre in Zeebrugge, Belgium.
