Marine transportation-technological systems safety and development

Abstract

The article deals with marine hydraulic structures design and operation, considering the influence of various superstructures and reloading equipment. The analysis of seismic resistance of the hydraulic structures erected in the seismic regions of Ukraine has shown that the actual seismic loads on the structures significantly exceed the design loads being determined by regulatory documents prior to 2006. In the era of globalization, transformation of cargo flows, changes in their structure, the issue of ports planning development, implying port capacities balanced development, namely: sea zone port zone, and land zone development, becomes particularly important. The design of hydrotechnical structures should be carried considering the transshipment complexes at the quay with proper scientific support.

The methodical peculiarities of the investigation of portal crane rolled steels degradation

“…The most common type of transshipment machines in seaports are portal cranes and transshipment cranes, due to which the main part of loading and unloading operations is carried out. Their safe long-term operation is an important scientific and technical problem [1,2]. Mechanical structures operate in the mode of multi-cycle loading, which is the main factor in significant degradation of the initial mechanical properties, and hence the high risk of crane destruction [3].…”
