1. A system comprising:
- a structure;
from 1 to 10 dynamic tension sensors, adapted to monitor a dynamic tension level of at least a first set of points along a length of the structure; and
a controller adapted to calculate a dynamic bending stress or strain level at a second set of points along the length of the structure as a function of time, wherein the second set of points do not comprise dynamic tension sensors;
wherein the structure comprises one or more strakes and/or fairings adapted to lower the vortex induced vibration value of the structure.

Abstract
There is disclosed a system comprising a structure, from 1 to 10 dynamic tension sensors, adapted to monitor a dynamic tension level of at least one point along a length of the structure, and a controller adapted to calculate a dynamic bending stress or strain level at a plurality of points along the length of the structure as a function of time. In some embodiments, the system also includes a vessel connected to the structure, wherein the vessel is floating in a body of water.

14. A method of calculating a dynamic tension level at a plurality of points along a length of a structure, the method comprising:
-
providing a structure; attaching from 1 to 10 dynamic tension sensors to the structure; monitoring a dynamic tension level of at least a first set of points along a length of the structure with the sensors; transmitting the dynamic tension level of the first set of points to a controller; and calculating a dynamic bending stress or strain level at a second set of points along the length of the structure as a function of time with the controller, wherein the second set of points do not comprise dynamic tension sensors; wherein the structure comprises one or more strakes and/or fairings adapted to lower the vortex induced vibration value of the structure.
