Beschreibung
Zusammenfassung:	An offshore system comprising: a dynamic submarine power cable (11), a bend stiffener (9) having a lower end (9b) and a top end (9a), the bend stiffener (9) having a central channel (9c) extending from the lower end (9b) to the top end (9a), the central channel (9c) receiving the dynamic submarine power cable (11) with a radial spacing between an inner surface of the central channel (9c) and an outer surface of the dynamic submarine power cable (11) along the length of the dynamic submarine power cable (11) arranged in the bend stiffener (9), the radial spacing forming a longitudinal water channel between the bend stiffener (9) and the dynamic submarine power cable (11), and an offshore structure tube (7) connected to the bend stiffener (9), wherein the offshore structure tube (7) has an inner tube channel (7a) in fluid communication with the longitudinal water channel, and wherein the offshore structure tube (7) has a through-opening (7b) extending from the inner tube channel (7a) through a wall (7c) of the offshore structure tube (7) to enable water (13) flowing from the lower end (9b) through the bend stiffener (9) to exit the offshore structure tube (7) via the through-opening (7b) to provide water cooling of the dynamic submarine power cable (11) in the bend stiffener (9), or wherein the bend stiffener has a radial through-opening (9d) arranged within ¼, 1/5 or 1/10 of a total axial length of the bend stiffener, defined by a distance between the lower end (9b) and the top end (9a), from the top end (9a) to enable water (13) flowing from the lower end (9b) through the bend stiffener to exit the bend stiffener (9') via the radial through-opening to provide water cooling of the dynamic submarine power cable (11) in the bend stiffener.
