The bulk of those are expected to come through plans from Norwegian oil services group Aker Solutions to develop its west London offices into an engineering hub, creating 1,300 jobs by 2015. It currently has around 3,100 employees in the UK. More concrete announcements on companies" expansion and investment plans are expected after Mr Cameron and his Norwegian counterpart Jens Stoltenberg on Thursday meet senior executives from ten energy companies, including Aker, National Grid, Centrica, Shell and Norway's state-owned giant Statoil. The two leaders will on Thursday outline plans to strengthen the energy links between their countries, by working together on long-term gas supplies, oil and gas exploration, investment in renewable energy and electricity interconnection. In addition, a joint business advisory group will be set up to allow companies to talk to government directly about how to spur on investment and to encourage new technologies, such as carbon capture and storage. "I hope that my visit to Oslo will help secure affordable energy supplies for decades to come and enhance investment between our two countries," Mr Cameron said. This will mean more collaboration on affordable long-term gas supply, more reciprocal investment in oil, gas and renewable energies and more commercial deals creating thousands of new jobs and adding billions to our economies. The two countries have energy ties dating back decades, as Norway supplies much of Britain's primary energy needs. The UK and Norway are already working together on major renewable projects such as Dogger Bank, the world's largest offshore wind project. Norway, oil-rich and Europe's second biggest gas supplier after Russia, is seen a desirable partner for the UK given its proximity, stable politics and huge reserves.
