What is the minimum strength that must be maintained by the strength member when the umbilical is tensioned?

The minimum strength that must be maintained by the strength member of an umbilical when it is tensioned is 4400 pounds. This specification ensures that the umbilical can withstand the forces experienced during diving operations, including the weight of the equipment and any dynamic loads that may occur while the diver is submerged. Maintaining this minimum strength is critical for diver safety, as it helps prevent the failure of the umbilical, which could lead to hazardous situations. The design criteria for such diving systems incorporate safety factors to account for these tensions, ensuring that even under maximum operating conditions, the umbilical will remain intact and functional. This standard allows for both safety and reliability in underwater operations.
