Abstract
Collisions of small ships are one of main dangers for the
offshore wind turbines. Using inflatable structures
surrounding the tower on the water level is a possibility
of effective protection. Modelling of such structures is
based on interaction between solid wall and fluid
enclosed inside. Inflatable structures can be adapted to
various impact schemes by adjusting initial pressure and
controlling release of compressed air by opening
piezo-valves. Simulations of ship collision with 2D model
of wind turbine tower protected by pneumatic structure
are presented in the report. Numerical analysis is
performed using ABAQUS/Standard and ABAQUS/Explicit.
Performed feasibility study proves that inflatable
structures can protect wind turbine tower and ship
against serious damages.
