North Sea oil rigs and wind farms should be guarded by the navy and air force to protect against potential Russian attacks, OEUK has warned.
Offshore Energies UK is pushing for energy assets to be classed as "critical national infrastructure" which would bring them under the defensive remit of the military.
The Times reports the call for increased defence comes amid a rise in Russian drones and suspicious activity in and around Scottish waters.
Graham Skinner, OEUK's Security Policy Manager, confirmed that both oil rigs and wind turbines had been put at risk during incidents over the last two years.
Speaking to The Scotsman, Mr Skinner said: “It is absolutely time to review those designations and ensure that infrastructure such as ours, that is vital, is included.
“It would pull those designated industries more comprehensively into national government exercises, tabletops and military planning.
"It absolutely elevates the importance of those installations right across government activity.”
Mr Skinner said drones had been spotted "loitering" in close proximity to offshore installations, adding: “We don’t know who has sent them there but they’re in the middle of the North Sea.
"They are very far from shore, so it’s unlikely to be hobbyists.
“It’s more likely to be something with significant criminal capability or state backing.”
Warning of the possible impact a coordinated attack could have in disrupting UK energy supplies, Mr Skinner cautioned: "We can’t just keep our heads in the sand.
