What material type is the strength member typically made from?

The strength member in diving systems, also known as the umbilical, is typically made from synthetic line. This material is chosen because it offers excellent tensile strength, flexibility, and resistance to environmental factors such as water and UV light. Synthetic lines, such as nylon or polyester, can absorb shock better than natural fibers or other materials, which is crucial in underwater applications where movements and loads can vary significantly.

Additionally, synthetic lines can be manufactured in various diameters and constructions, allowing for customization based on the specific requirements of the dive operation. The lightweight and durable nature of these materials enhances the overall efficiency and safety of surface-supplied diving systems, making them a preferred choice in the industry.
