Surface-Supplied Diving Equipment

Introduction to Surface Supply

Surface-supplied diving is a specialized form of underwater diving where divers receive breathing gas via an umbilical connected to the surface. This umbilical typically includes a gas supply line, a depth gauge (pneumofathometer), and a communication cable, allowing for continuous support and monitoring from the surface. Unlike traditional SCUBA diving, which relies on self-contained breathing apparatus, surface-supplied diving offers significant advantages, including a larger gas supply and enhanced safety features, making it ideal for professional and commercial applications.

Course Overview

The Surface-Supplied Diving Equipment course is designed to provide participants with foundational knowledge and practical skills in surface-supplied diving techniques. The course includes both theoretical instruction and hands-on training in confined and open-water settings. Participants will learn about various aspects of surface-supplied diving, including:

• Equipment Familiarization: Understanding the components of surface-supplied systems, such as Kirby Morgan helmets and umbilicals.
• Operational Procedures: Learning dive planning, emergency procedures, and safety protocols essential for effective diving operations.
• Practical Skills Development: Engaging in exercises that simulate real-world scenarios divers may encounter during commercial diving tasks.

Minimum Equipment: 

• full-face mask or helmet 
• diver’s umbilical
• bailout system connected to the primary system by a valve operated by the diver 
• full-body safety harness 
• voice communication system between the divers and the surface control point 
• surface-breathing gas panel 
• suitable supply of breathing mixture
