Aircraft from RAF Lossiemouth will be used to help protect offshore oil and gas assets amid concerns about sabotage attempts by Russia.
Energy Voice says the operation is likely to involve P-8 Poseidon sub-hunting jets from the air base.
It is part of greater military action in the North Sea intended to increase protection for offshore installations.
The threat level rose after the suspected sabotage of the Nord Stream gas pipelines in the Baltic Sea - although Russia has denied any involvement in a series of explosions that caused huge leaks.
As well as helping Norway, the RAF Lossiemouth planes are expected to safeguard the Langeled pipeline that carries Norwegian natural gas to the UK.
Energy industry sources have confirmed that no incidents had occurred in British waters, but precautions were being taken.
Unidentified drones
Norway mobilised its armed forces to protect its oil and gas platforms last week after unidentified drones were seen.
Defence sources say the RAF Lossiemouth planes would provide a wide-area surveillance picture of activity around oil and gas infrastructure.
Poseidon jets can drop sonobuoys - underwater listening devices - to detect hostile submarines or drones.
An inner protection ring would be provided by the Royal Navy and Royal Marines commandos.
A senior naval source said: "Nato has made it clear to Moscow that sabotage would be met with a united and determined response."
The Maritime Autonomous Systems Trials Team, based in Faslane, now has drones that can monitor large areas of the seabed. Naval sources said they could pick up signs of sabotage activity.
Risk of gas shortages
Meanwhile, an industry regulator says Britain is facing "a significant risk" of gas shortages this winter.
Ofgem said that, due to Russia's war with Ukraine, there is a possibility the UK could enter a "gas supply emergency".
This would lead to supplies being cut to power stations which use gas to generate the country's electricity.
Gas-fired power stations generate between 40% and 60% of the UK's electricity.
Ofgem said: "Due to the war in Ukraine and gas shortages in Europe, there is a significant risk that gas shortages could occur during the winter 2022-23 in Great Britain. As a result, there is a possibility that Great Britain could enter into a gas-supply emergency."
If this happens, supplies would be cut to "the largest gas users" which are likely to be large gas-fired power stations which produce electricity to the National Electricity Transmission System.
Energy rationing?
It is not clear if this could result in electricity blackouts, or mean homes and businesses will face energy rationing this winter.
During the Conservative Party leadership campaign, Prime Minister Liz Truss ruled out rationing.
Asked about the risk of blackouts this winter, Ofgem told the BBC: "This winter is likely to be more challenging than previous ones due to the Russian disruption of gas supplies to Europe."
But it said: "Britain is in a good position with little direct import of gas from Russia. Nevertheless, we need to be prepared for all scenarios this winter."
