What are the major assemblies of the KM37 portable surface supplied diving system?

The major assemblies of the KM-37 portable surface supplied diving system include the helmet, umbilical, harness, and emergency gas supply (EGS). The helmet is essential for providing the diver with protection, communication capabilities, and access to breathing gas. The umbilical serves as the lifeline connecting the diver to the surface power source, supplying air or other breathing gas, delivering communications, and providing vital safety features.

The harness is designed to support the diver and allow for ease of mobility and secure attachment of the diving system components. The emergency gas supply (EGS) is a critical safety feature that provides an additional source of breathing gas in case of an emergency, enhancing the diver's safety during operations. Together, these assemblies form a comprehensive system that allows for effective and safe underwater operations, highlighting the importance of each component in ensuring successful dives.
