Analyses for dolphin design after Blum and using the p-y method with GGU-DOLPHIN (33min)

This webinar will demonstrate the GGU-DOLPHIN program’s ability to analyse and design dolphins. Both the Blum’s method and the p-y-method can be applied. The Recommendations of the Committee for Waterfront Structures “EAU” presents both methods as equivalent and possible ways to design dolphins. Depending on the application, dolphin piles are exposed to different actions. Breasting dolphins must be capable to accept the actions exerted by the mooring process. Design is performed by specifying the ship's...

GGU-DOLPHIN analysis and design of dolphin piles (62min)

Welcome to the introduction to the programm GGU-DOLPHIN.

GGU-DOLPHIN allows the analysis and design of dolphin piles which are loaded horizontally in most cases. After a short introduction you will see the menues of the hole program and some examples. 

We have made this short training course available to you free of charge.
