STS crane height increase and life extension

To make an existing STS crane future-proof, Antwerp Terminal Services investigated the possibility of an adaption to increase the crane’s height and extend its life. To do this, it first had to be determined whether these adaptions were technically feasible.

Iv assessed the feasibility of the project using a wind tunnel test and a shadow model of the crane. Using the developed FEA model, global strength, fatigue, natural frequencies, stability, and wheel loads were analyzed. Additionally, Iv assisted in drafting the Request for Quote and in the technical evaluation of the quotations.

A wind tunnel test was performed to assess the wind load accurately. Iv made a 3D model as a basis for the scale model for the wind tunnel test and an FEA model of the existing and adapted crane to process the results. The results were analysed, and the wind load was adjusted accordingly so that the corner loads and stability of the crane could be evaluated.

With these analyses, Iv provided the client with reliable advice on the feasibility of increasing the height of the crane, its service life and the necessary adaptions. Iv served as the client’s key support, managing various responsibilities, providing documentation and substantiation, supporting discussions with suppliers and answering their questions.
