North Sea, an area of ocean located between Britain and the countries of Northern Europe, roughly equal in size to the British mainland.
It was once a crucial source of fishing resources for Europe, being one of the world's four major fishing grounds, and also important for oil and natural gas resources, ranking as the world's ninth largest oilfield.
In the past, the North Sea undoubtedly held significant status and value for Europe. Its fishery and oil and gas resources were of substantial importance to Europe, even becoming one of the pillars of the European economy.
This sea area's depth is mostly around one hundred meters, making it one of the world's well-known shallow seas, which meant extracting seabed resources was relatively easy.
Thus, before the disaster, the oil and natural gas resources here were completely divided among neighboring countries, and after World War II, numerous extraction platforms were built.
