Study of vessel impacts on jacket-type structures

Use of advanced calculation techniques known as Numerical Nonlinear Finite Element Analysis (NLDEA).

Collisions between wind turbines and ships are a real possibility.

A research project has been carried out to study the possible consequences of ship impacts on jacket-type offshore foundations for wind turbines.

Nowadays, the number of wind turbines installed offshore is growing more and more due to the stable and constant wind flow and the avoidance of problems related to onshore wind farms, such as noise pollution or visual impact. Collisions between wind turbines and ships are a real possibility.

To date, these collisions have received limited attention in the offshore wind industry. However, collisions can result in significant damage and even global collapse of structures.

The analysis was performed using advanced calculation techniques known as Numerical Nonlinear Finite Element Analysis (NLDEA). All calculations were carried out in accordance with DNVGL-OS-A101, DNVGL-OS-C101, DNVGL-ST-0126 and DNVGL-ST-4037.
