The state of metal structures of port handling machines in Ukrainian ports is alarming due to several problems, such as corrosion, mechanical wear, lack of modernizations, limited resources for maintenance and insufficient application of modern control methods. Over time, structures that have been in operation for several decades are subject to significant wear and tear, which reduces their load-bearing capacity and increases the risk of accidents. The humid marine environment contributes to corrosion, while the stresses of transhipment machinery cause material fatigue and cracking. Lack of modernisation and limited funding for maintenance often lead to accidents. Irregular use of modern non-destructive testing methods makes it difficult to detect hidden defects on time. This paper examines the problems and potential solutions regarding the condition of metal structures of port handling machines in Ukrainian ports. Several major problems are identified, such as corrosion, mechanical wear, lack of modernisation and limited maintenance funding. In particular, methods are used to assess the stress-strain state of metal structures of portal cranes, a combination of the analytical finite element method (FEM) and the experimental method of strain measurement. As a result, the integration of FEM and strain gauging has made it possible to obtain accurate data on the condition of structures, which is critical to ensuring their safety and efficiency in operation.
