Presentation & History
STRUDL-X is a general Finite Element software with specific extensions for the Offshore Oil & Gas and Wind domains, including Environmental Actions, Code Checking and Fatigue Analysis.
STRUDL-X is developed and maintained at STRUSIM since 2004 by a team of Senior Structural Engineers, involved in numerous R&D projects, to meet the needs of the industry.
STRUDL-X is the successor of NSO (New Strudl Offshore) derived from BV-STRUDL, developed by Bureau Veritas / C. Briwand from the IBM version of STRUDL, derived itself from the original Massachusetts Institute of Technology (MIT)’s STRUDL-II program initiated in the 70’s.
