Drop device for fundamental hydro-elastic research
General information
The standard design practice for the prediction of the response of marine structures due to wave loads neglects the interaction between the structural vibrations and the hydrodynamic force. In addition this standard design practice neglects the influence of the dynamic properties of the marine structure in the coupling between the motions (both rigid body and structural vibrations) of the structure and the hydrodynamic force.
The hydro-elastic design practice on the other hand intends to incorporate this complex chain of cause and effect of the hydrodynamic force on, the motions of and the dynamic properties of the marine structure in the prediction of the response. The correctness of this analysis method and the prospective of refined and conclusive advice capabilities drive MARIN to invest in this design practice in cooperation with our clients.

MARIN uses its experience for the development of hydro-elastic analysis tools (numerical and experimental) and hydro-elastic expertise in order to answer the present and future challenges of our clients. MARIN studies the following issues in cooperation with our clients:
- Model experiments for investigation of the global response (whipping & springing) by application of segmented models
- Dynamic response of membrane containments systems to sloshing impact in partially filled LNG tanks
- Fundamental research toward the importance and the effect of a hydro-elastic analysis in order to know when it is worthily and justified to come up with the effort of performing hydro-elastic analysis
