Abstract
This article presents the results of topology optimization of various non-rotating floating crane solutions. Based on the analysis of classical floating crane solutions, the main types of such cranes have been identified, for which optimization calculation models have been substantiated, which allow us to identify the most rational floating crane solutions. Based on the same modeling principles, models have been prepared and topology optimization of floating cranes located on two separate pontoons has been carried out. The floating crane solution on two pontoons, unlike classical designs, allows for more efficient use of the capabilities of pontoons used in floating cranes. The optimization models proposed in the article also allow for practical recommendations to be prepared on methods for reinforcing pontoon structures of floating cranes.
期刊介绍:
This journal aims to provide a medium for presentation and discussion of the latest developments in research, design, fabrication and in-service experience relating to marine structures, i.e., all structures of steel, concrete, light alloy or composite construction having an interface with the sea, including ships, fixed and mobile offshore platforms, submarine and submersibles, pipelines, subsea systems for shallow and deep ocean operations and coastal structures such as piers.
