Abstract

Method for estimating section forces including bending moments on a subsea component, the subsea component being connected to a riser and a well, wherein the method comprises the steps of; -measuring the section forces and/or deformations in a lower section (A) and a first upper section (B) at the lower part of the riser by the use of at least two independent measuring devices, -measuring the inclination and acceleration of the subsea component using a set of sensors placed in a location of the subsea component (section E), -calculating the section forces for any section (Z) of the subsea component by the use of a processing device adapted for receiving data from said measuring devices and performing calculations, the calculations involving: -an assessment of dynamic equilibrium for the subsea component and the part of the riser below the lower section (A)including load terms - considering the magnitude and directionality of section forces in the section (A), and - gravitational and inertia forces for the subsea component based on said measurements.
