PROGRAMS FOR ALLSTRUCTURAL PROJECTSA UNIQUELY DEVELOPED SOFTWARE THAT MEETSSTRICT DEMANDS FOR DOCUMENTATION ANDVERIFICATIONThe Ramboll Oshore StructuralAnalysis Programs - ROSAP -havebeen developed over the past30+years to meet the ever increasingdemands for structural design,optimisation and lifetime extensionof oshore structures.The program development has beendrivenin close cooperationwithRamboll's structural expertsand ateam of analysts anddesigners. A further invaluable bondtoleading oiland gas operators inthe Danish oshore sector hassecured a focused eort to providehigh standards and oering theright analysis tools to the market.Theoperators have been activelyinvolvedin providing specialistknowledge supported bybackground studies anddocumentation.The ongoing development of theprograms is based on detailedinsight in currentmarketdemandsandclientneeds. This strongposition makes ROSAP a unique,user-friendly and up-to-datedesigntool that can be tailored forany structural project.

Tools for design, re-assessmentand lifetime extension

ROSAPprovide indispensable toolsfor new design, modication workand lifetime extension assessmentsof onshore and oshore steelstructures.The programs provide a completepackage for static and dynamicanalyses of spatial framestructures,covering all phases fromtransport and liftingto in-service.Loads, such as hydrodynamic, wind,constant force and accelerations,are intuitively dened andprocessed according to recognisedtheories and standards.

Tailor-madeprograms forstructural design needs

The primary programs in ROSAPare:

ROSA RONJA STRECH TUBJOI RHSJOI JOANA FATIMA

ROSA is the main nite elementprogram for static and dynamicanalysis and can in combinationwith FATIMA be used for spectralortransient analysis.

The advanced program RONJAsupplements ROSA by addingfacilities for non-linear analysis ofstructures with large displacementsand non-linear elasto-plasticmaterial behavior. RONJA iscommonly used for determinationof global failure of structures takingforce redistribution into account inrelation to e.g.ship impactassessments or post damageanalyses.The STRECH program is anessential postprocessor developedfor stress and stability check ofbeam members.The program supports a number ofcodes such as: API AISC NORSOK ISO EC3 DS449TUBJOI, RHSJOIand JOANA arepostprocessors aimed at accurateand automated verication ofcommonly used joint connections.TUBJOI is dedicated to tubular jointconnections typically used in jacketstructures.RHSJOI is tailored fortypical RHS prole connections.JOANA is developed for stress

check of typical joints applied intopside structures. The programsupports, among others, vericationof ring stieners, gusset plateconnections and other standardconnection details. The jointverications made with TUBJOI,RHSJOI and JOANAfollow thesame codes as the STRECHprogram.FATIMA is used for fatigue analysisof members and joints.

Comprehensive applicationperformance

All programs have been used foranalysis of the vast majority ofjackets, topsides, oshore bridgesand risers within the Danish sectorof the North Sea. In addition, severalstudies have been carried out in theMiddle East, UK, US and Norway.ROSAP have also been used fordesign and documentation of morethan 1,200 individual foundationdesigns for wind turbines for 21oshore wind farms around theworld.
