Diver's umbilical
Diver's umbilical is a critical component of the diving equipment used by commercial divers. It is a combined physical link and lifeline that connects the diver to the surface control point, typically a diving support vessel or a diving bell. The umbilical serves multiple functions, including the supply of breathing gas, communications, power for tools, and a guide to the diver's location.
Components[edit | edit source]
The diver's umbilical is made up of several components, each serving a specific function:
- Breathing gas supply hose: This hose carries the breathing gas from the surface to the diver. The gas can be air, nitrox, heliox, or trimix, depending on the depth and nature of the dive.
- Communications cable: This cable allows for two-way communication between the diver and the surface. It can carry both voice and data signals.
- Pneumo hose: This hose is used to measure the diver's depth by applying a known pressure at the surface and measuring the pressure at the diver's end.
- Strength member: This is a load-bearing component that provides physical strength to the umbilical. It is designed to withstand the forces exerted on the umbilical during the dive.
Function[edit | edit source]
The diver's umbilical is a critical part of the surface-supplied diving system. It provides the diver with a continuous supply of breathing gas, allows for communication with the surface, and serves as a guide rope for the diver. The umbilical is typically managed by a dive team member on the surface, who ensures that it is not entangled or damaged during the dive.
Safety Considerations[edit | edit source]
The safety of the diver's umbilical is paramount in commercial diving operations. Regular inspections and maintenance are required to ensure its integrity. Any damage or wear can lead to a failure of the umbilical, which can be life-threatening for the diver. Therefore, strict diving safety protocols are followed in the use and handling of the diver's umbilical.
