Underwater operations involve activities conducted beneath the surface of water, typically in oceans, lakes, or rivers. These operations can include tasks such as scuba diving, submarine exploration, and underwater construction. They are essential for various industries, including marine research, oil and gas, and environmental monitoring. Professionals engaged in underwater operations often use specialized equipment like diving suits, submersibles, and remotely operated vehicles (ROVs). Safety is a critical concern, as divers and operators must be trained to handle the unique challenges of underwater environments, such as pressure changes and visibility issues.
