Saturation diving is a deep-sea diving technique that allows divers to stay underwater for extended periods. Divers live in a pressurized environment, usually in a special diving chamber, which reduces the risk of decompression sickness when they return to the surface. This method is commonly used in underwater construction, oil drilling, and scientific research. During saturation diving, divers are transported to the work site in a pressurized bell. They can work at great depths, often exceeding 1,000 feet, without needing to resurface frequently. This technique is essential for projects involving subsea pipelines, offshore oil rigs, and marine biology research.
