DESCRIPTION:Sub-sea structures form a critical part of the national infras
 tructure for energy extraction\, transportation of fluids and for communic
 ations\, amongst others. Examples of sub-sea structures are gas pipelines\
 , cables for exporting electricity from offshore wind farms\, submarine te
 lecommunication lines\, and risers for lifting oil and gas from sub-sea we
 lls to surface platforms. These sub-sea structures must operate in the ext
 reme conditions of the seas and oceans.\n\nAnalysis is a critical part of 
 sub-sea engineering. Structural analysis in sub-sea engineering has to ove
 rcome the challenges of limitations on computing power\, data uncertainty\
 , and the behaviour of structures in the marine environment. The consequen
 ces of failure can be catastrophic in the case of oil and gas infrastructu
 re.\n\nChallenges for analysis include the geometric non-linear behaviour 
 of flexible structures under dynamic loads\, structure-seabed interaction\
 , and calculating the hydrodynamic loading on structures. Increasing compu
 ting power and experience with existing structures is helping engineers to
  perform analysis that was unfeasible until recently. Improvements in anal
 ysis techniques are leading to increased optimisation and reduced risk in 
 the design\, construction and operation in sub-sea engineering.\n\n
