Abstract:
Stress reducing system and associated method for reducing stresses at a desired position in an offshore production or drilling system, the offshore production or drilling system comprising: a seabed structure, a floating structure and a riser ( 24 ) extending there between, the riser being tensioned, the riser ( 24 ) comprising at least a first part ( 45 ) and a second part ( 46 ), which second part ( 46 ) is connected to the first part ( 45 ) via a flexible connection ( 20 ) allowing an axial, angular and/or rotational movement between the first and second parts ( 45, 46 ), said stress reducing system comprises:—a first sensor ( 41 ) for real-time monitoring of stresses at the desired position, positioned at or close to the desired position ( 20 ),—an actuating system ( 42 ) arranged at the flexible connection ( 20,  the actuating system ( 42 ) being connected to said first and second parts ( 45, 46 ), and wherein the actuating system ( 45, 46 ) is configured to apply a force to the first or second part ( 45, 46 ) when the first and second parts ( 45, 46 ) are moved out of a neutral position,—a control system ( 40 ) adapted to receive monitoring data from the first sensor ( 41 ), wherein the control system ( 40 ) is connected to the actuating system ( 42 ) and is able of providing instruction signals to the actuating system ( 42 ), wherein the control system ( 40 ), based on said monitoring data from the first sensor ( 41 ), is able to calculate a real-time set of data for control of the applied force of the actuating system ( 42 ) and instructing the actuating system ( 42 ) to act accordingly, such as to reduce the stress at said desired position.

Claim (Index 2):
The system according to  claim 1 , wherein the stress results in bending moments at said desired position, wherein the flexible connection is a flexible joint allowing angular displacement of the first part relative to the second part, wherein the first sensor is configured to provide real-time monitoring of bending moments at the desired position, wherein the actuating system is configured to apply the force is in the same direction as the movement of the first part relative to the second part out of neutral position, and wherein the control system is configured to calculate the real-time set of data for control of the applied force of the actuating system in order to provide a reduced bending moment at said desired position.
