Unlocking the Massive Gas Field at the Bottom of the North Sea

TLDRA team of engineers from Norsk Hedro are embarking on a challenging project to extract natural gas from the Foreman Lag gas field, located 120 kilometers off the coast of Norway. This massive underwater gas field has the potential to supply 20 years' worth of natural gas to the UK, but it poses numerous engineering challenges due to its depth and remote location. The engineers plan to overcome these challenges by building an underwater gas platform, drilling wells, and constructing the world's longest sub-sea pipeline to transport the gas to the UK.

Key insights

⛽️The Foreman Lag gas field contains over 300 billion cubic meters of gas, enough to supply the UK's gas needs for 40 years.

🛢️The UK is increasingly relying on natural gas to power its economy, as coal is no longer sustainable.

💰The project will cost $10 billion and take 10 years to complete, with the potential to bring significant economic benefits to both Norway and the UK.

🔌The gas platform will be powered by a 125-kilometer control cable, which will also provide communication and hydraulic capabilities.

🌊The engineers face challenges such as drilling through the seabed, trenching the rough sea floor, and adapting the system to handle the unique properties of the Ormen Lange gas.

Q&A

How much gas is in the Foreman Lag gas field?

—The Foreman Lag gas field contains over 300 billion cubic meters of gas, making it one of the largest underwater gas fields in the North Sea.

Why is the UK turning to natural gas?

—The UK is transitioning away from coal and increasingly using natural gas to power its economy due to its lower carbon emissions and sustainability.

How long will it take to complete the project?

—The project is estimated to take 10 years to complete, including drilling the wells, constructing the gas platform, and building the sub-sea pipeline.

How will the gas be transported to the UK?

—The processed gas will be transported to the UK through the Langeled pipeline, a 1,200-kilometer sub-sea pipeline that connects Norway to the UK.

What are the main engineering challenges of the project?

—The main challenges include drilling through the seabed, trenching the rough sea floor, adapting the system to handle the unique properties of the Ormen Lange gas, and building the world's longest sub-sea pipeline.
