surface supply diving

Surface supply diving involves divers receiving breathing gas from a facility on the surface through a long hose or umbilical. The diving team remains connected to this surface source, allowing them to work underwater for extended periods without carrying large amounts of breathing equipment, and provides a continuous supply of fresh air or breathing mixture. This method enhances safety and efficiency for tasks like underwater construction, inspection, or maintenance, especially in complex or long-duration dives. It relies on specialized equipment, proper communication, and careful procedures to ensure diver safety underneath the water.
