Definition(s)
Global Analysis
Analysis of the complete riser string from the sea floor (wellhead) to top including tensioner joint.
NOTE Bending moments and effective tension distributions along the riser string due to functional loads, vessel motions and environmental loads are determined by global analysis.

Global Analysis
Determination of a consistent set of internal forces and moments, or stresses, in a structure that are in equilibrium with a defined set of actions on the entire structure. NOTE 1 When a global analysis is of a transient situation (e.g. earthquake), the inertial response is part of the equilibrium. NOTE 2 Adapted from ISO 19902:2007, definition 3.23.
