OMAE2017-62643 New Combined CFD and Model Testing Technique for Identification of Wave Impact Loads on a Semisubmersible

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1505407

A procedure is presented describing how to estimate realistic loads using combined numerical and model test data. Measured platform motions are imposed on the structure during the CFD analysis. The combination of the wave matching procedure with the imposed measured platform motion gives a very good...

Impact Loads From Drop Test of a Circular Section With 42 Force Transducers

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1282870

Results from previous model test campaigns of various large-volume platforms indicate that wave impact loads on vertical platform columns can become high in extreme sea states. Moreover, column slamming is a highly non-linear and complex problem and reliable estimation of Ultimate Limit State (ULS) ...

Second-order random wave kinematics and resulting loads on a bottom-fixed slender monopile

http://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1074202

The importance of including second-order nonlinear random wave kinematics in the numerical prediction of drag-induced shear forces and moments, at various levels on a bottom-fixed slender monopile in 40m water depth, is investigated. A vertical circular cylinder of diameter 0.5m is considered, repre...
