Offshore System Comprising a Dynamic Submarine Power Cable - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240014643 titled 'Offshore System Comprising a Dynamic Submarine Power Cable
Simplified Explanation
The abstract describes an offshore system that includes a dynamic submarine power cable, a bend stiffener, and an offshore structure tube. The bend stiffener has a central channel that receives the dynamic submarine power cable with a radial spacing between the inner surface of the central channel and the outer surface of the cable. This radial spacing creates a longitudinal water channel between the bend stiffener and the cable. The offshore structure tube is connected to the bend stiffener and has an inner tube channel in fluid communication with the longitudinal water channel.
- The bend stiffener provides support and protection to the dynamic submarine power cable.
- The radial spacing between the bend stiffener and the cable allows for the flow of water, enabling water cooling of the cable.
- The offshore structure tube is connected to the bend stiffener and provides additional support and protection.
- The inner tube channel of the offshore structure tube allows for the flow of water, further enhancing the water cooling of the cable.
Potential applications of this technology:
- Offshore renewable energy systems, such as offshore wind farms, where dynamic submarine power cables are used to transmit electricity from the turbines to the shore.
- Subsea oil and gas installations, where dynamic submarine power cables are used to power various equipment and systems.
Problems solved by this technology:
- Overheating of dynamic submarine power cables due to the continuous flow of electrical current.
- Damage to the power cables caused by bending and external forces.
- Ensuring efficient and reliable power transmission in offshore environments.
Benefits of this technology:
- Improved cooling of dynamic submarine power cables, leading to increased efficiency and lifespan.
- Enhanced protection and support for the power cables, reducing the risk of damage.
- Increased reliability and performance of offshore power transmission systems.
Original Abstract Submitted
an offshore system including: a dynamic submarine power cable, a bend stiffener having a lower end and a top end, the bend stiffener having a central channel extending from the lower end to the top end, the central channel receiving the dynamic submarine power cable with a radial spacing between an inner surface of the central channel and an outer surface of the dynamic submarine power cable along the length of the dynamic submarine power cable arranged in the bend stiffener, the radial spacing forming a longitudinal water channel between the bend stiffener and the dynamic submarine power cable, and an offshore structure tube connected to the bend stiffener, wherein the offshore structure tube has an inner tube channel in fluid communication with the longitudinal water channel, and wherein a) the offshore structure tube has a through-opening extending from the inner tube channel through a wall of the offshore structure tube to enable water flowing from the lower end through the bend stiffener to exit the offshore structure tube via the through-opening to provide water cooling of the dynamic submarine power cable in the bend stiffener, or b) the bend stiffener has a radial through-opening arranged within � of a total axial length of the bend stiffener, defined by a distance between the lower end and the top end, from the top end to enable water flowing from the lower end through the bend stiffener to exit the bend stiffener via the radial through-opening to provide water cooling of the dynamic submarine power cable in the bend stiffener.
