Surface-supplied diving skills

Surface-supplied diving skills are a set of competencies required for the safe and efficient use of surface-supplied diving equipment. This type of diving is a mode of diving where the diver is supplied with breathing gas from the surface, either from the shore or a diving support vessel.

Overview

Surface-supplied diving skills encompass a wide range of abilities, including the operation of the diving equipment, communication with the surface, emergency procedures, and underwater work skills. These skills are typically acquired through a combination of formal training and on-the-job experience.

Diving Equipment Operation

The operation of surface-supplied diving equipment is a critical skill. This includes understanding the function and maintenance of the diving helmet, diving suit, and umbilical, which supplies the diver with breathing gas, communications, and sometimes heated water or power for tools.

Communication Skills

Communication with the surface is vital in surface-supplied diving. Divers must be proficient in the use of underwater communication systems, including both hard-wire and through-water communications. They must also understand and use standard diving signals for communication with the surface and with other divers.

Emergency Procedures

Divers must be trained in emergency procedures, including the use of diver rescue techniques and emergency ascent procedures. They must also be familiar with the operation of diving bells and hyperbaric chambers for decompression and treatment of diving disorders.

Underwater Work Skills

Underwater work skills include the use of underwater tools, underwater welding and cutting, and underwater construction. Divers must also be able to navigate underwater, using techniques such as underwater navigation and archaeological surveying.

Training and Certification

Training in surface-supplied diving skills is provided by a number of organizations, including commercial diving schools and military diving units. Certification is typically required for employment as a surface-supplied diver, and is regulated by organizations such as the Professional Association of Diving Instructors (PADI) and the Diving Certification Board of Canada (DCBC).
