Abstract
This study presents an analysis of floating cranes and the design of one such crane. During the analysis phase, various types of floating cranes and their structural designs were examined. Based on this analysis, the necessary calculations were performed to select a suitable crane and pontoon.
The study also investigates how different steel grades (S235 and S355) influence the selection of structural components. The emphasis is on ensuring the pontoon's structural integrity, assuming that the calculated plate thicknesses and profile dimensions will be implemented. Two software tools were utilised for the analysis: Mars Inland and Ansys. Furthermore, calculations adhered to the standards of Bureau Veritas, the French classification society, particularly Rule Note No. 217.
