I. Overview of umbilical cable
Umbilical cables, as the name suggests, are inspired by a baby’s umbilical cord, which connects the mother to the fetus and provides the fetus with the nutrients and oxygen it needs for life. In the field of engineering and technology, umbilical cables play a similar role by connecting equipment underwater or in special environments with external systems, providing these equipment with power, signaling, and possibly fluid (e.g., hydraulic power, chemicals, osv.) transport functions.
2.the field of application umbilical cable
1）Marine engineering
In offshore engineering, umbilical cable is a key component connecting underwater equipment such as floating production systems (e.g. FPSO), submersibles, ROVs (underwater robots), etc. with the upper platform or vessel. It can not only provide stable power supply for these underwater equipments, but also realize high-speed data communication and necessary fluid transmission, which is an indispensable infrastructure for activities such as marine oil and gas exploration, development, production, and marine scientific research.
2）Aerospace technology
In the field of spaceflight, umbilical cable also plays an important role. It may be used to connect a spacecraft to a ground station or other spacecraft to ensure power supply, signaling, and possibly fluid (e.g., fuel, coolant, osv.) management during mission execution. Although umbilical cables in aerospace differ from those in ocean engineering in terms of design and application, their roles in ensuring smooth mission execution are the same.
3）the structure of the composition
The structure of umbilical cables is complex and varied, depending on their application environment and required functions. Generally speaking, it contains the following main parts:
Cable unit
The cable unit is the part of the umbilical cable used to transmit power. It is usually made of highly conductive metal wires (e.g., copper, aluminum, osv.) and wrapped with insulation and sheathing layers to protect the internal metal wires from the external environment.
Optical fiber unit
Fiber optic cable unit is used to transmit optical signals to achieve high-speed, high-capacity data communications. It usually consists of optical fibers, reinforcing elements and sheaths, of which optical fibers, as a transmission medium, have the advantages of high bandwidth and low loss.
Fluid piping
In some applications, umbilical cables also need to contain fluid ducts to transmit fluids such as hydraulic power and chemicals. These pipes are usually made of corrosion-resistant, high-strength materials to ensure stable operation in harsh environments.
Sheathing and reinforcement
In order to protect the internal cables, fiber optic cables and fluid ducts from the external environment, umbilical cables are usually wrapped with sheathing and reinforcement layers on the outside. The sheath is usually made of polymer materials with excellent corrosion and abrasion resistance, while the reinforcement layer is usually made of high-strength materials such as steel wire or Kevlar to enhance the tensile and compression resistance of the umbilical cable.
3. Application of umbilical cables in the ocean
