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 13):
The system according to  claim 1 , further comprising:\n a second flexible connection which is either (a) positioned between the first part and the second part and is configured to allow the first and second parts to be angularly displaced relative to each other, or (b) positioned between the second part and a third part of the riser and is configured to allow the second and third parts to be angularly displaced relative to each; wherein the first sensor is configured to provide real-time monitoring of bending moments at the desired position; a second actuating system which is arranged at the second flexible connection, the second actuating system being connected to said second and third parts and being configured to apply a force to at least one of the second and third parts when the second and third parts are moved out of a neutral position relative to each other; wherein the second actuating system is configured to apply the force in the same direction as the movement of the second part relative to the third part out of neutral position; wherein the control system is adapted to receive monitoring data from the first sensor, the control system being connected to the second actuating system and being configured to provide instruction signals to the second actuating system; wherein the control system is configured to calculate, based on said monitoring data from the first sensor, a real-time set of data for control of the applied force of the second actuating system to provide a reduced bending moment at said desired position and instruct the second actuating system to act accordingly.
