Systems and methods are described for monitoring displacement on structural elements of subsea systems such as on components of a subsea pipeline network used to transport production fluid from a subsurface wellhead to surface facilities. The described techniques sense changes in displacement using a sensing blade, for example made of crystalline material such as sapphire, that is anchored to the structural element such that it is approximately perpendicular to the direction of sensed displacement. Displacement is sensed as bending of the sensing blade using one or more instruments fabricated on the blade. Robustness of design is in part provided by additional flexible non-sensing blades mounted in parallel to the sensing blade.

A system and method for monitoring bending curvature of a flexible pipe structure, including at least one conduit configured to conform to a profile of a bend stiffener of a flexible pipe structure, and the at least one conduit including one or more sensors, wherein each sensor is configured for measuring a bending curvature of the bend stiffener.

A pipeline alignment termination device comprises a connecting piece () connected at its first end to a pipeline (). The connecting piece is supported on a skid base () by an articulated support (). Adjustable constraints (, L) operable by ROV, permit the second end () to be accurately aligned by transverse and rotational adjustments with the end of a spoolpiece (). After alignment and connection, constraints on the rotation and transverse movement are removed, leaving the connecting piece supported but free to move with up to five degrees of freedom.
