Abstract
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 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.
