Offshore system comprising a dynamic submarine power cable

A method of cooling a dynamic submarine power cable of an offshore system having 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 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 wherein the bend stiffener has a radial through-opening arranged within ¼ 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,

• the method comprising:
• providing the bend stiffener such that the lower end is submerged in seawater, causing seawater to enter the longitudinal water channel,
• wherein the longitudinal water channel extends from the top end to the lower end of the bend stiffener along the entire length of the dynamic submarine power cable arranged in the bend stiffener,
• wherein at an interface between the bend stiffener and the dynamic submarine power cable where the dynamic submarine power cable enters the lower end of the bend stiffener, the outer surface of the dynamic submarine power cable and an outer surface of the bend stiffener form outermost surfaces of the offshore system.
