Novel Procedures for Sustainable Design in Structural Rehabilitation on Oversized Metal Structures

Abstract

This article includes several studies and advanced research carried out on the subject of large KANGUR-type port cranes, subjected to regular or interventional maintenance work; besides the beneficial effects for which they were intended, some undesirable effects were detected in terms of affecting safety in exploitation. The purpose of this paper is to identify the risk factors and to offer sustainable solutions for increasing operational safety and service life for the respective equipment, as well as for other similar fields of activity, including oversized structures. Following the theoretical studies and the experimental research carried out in situ that confirmed the validity of the theoretical models used, the article in conclusion provides specific and sustainable solutions as well as new methods of assessment, which combine the positive elements of the usual solutions, but in parallel, allow the elimination of the negative side effects that may occur in time. Hence, the article’s novelties also consist of a new approach to achieve structural interventions, resulting in the increase in the service life, and in parallel with that, the safety in operation of the respective equipment.

“…Selecting technological equipments that will lead to the achievement of highperformance technical and economic indicators becomes the essential issue that decides both the technological processing variant and the typology of technological equipment. A first research direction in the field was focused on the operating behavior of equipment and their reliability [1,2,3,4]. Obviously, the productivity of the equipment was also an important aspect taken into account [5,6,7].…”
