The technological process of ship engine overhaul begins with dismantling, while the obligatory operation is flaw detection of parts. The flaw detection at this stage involves certain difficulties due to the fact that the entire repair process takes place directly onboard the ship. It is possible to simplify the task of assessing the technical condition of a particular part, if one can assess the performance of this part before dismantling, saving both material assets and time. However, in vessel design, the equipment developers do not pay due attention to ensuring its controllability. The article describes capabilities of ultrasonic flaw detection that can be realized in ship conditions during the first stage of the ship engine overhaul technological process. The ultrasonic technique for estimation of a crank-shaft metal damage through scavenging ports of the ship engine is discussed; as well as an option to address the issue of repair or replacement of tap bolts according to their actual technical condition.The described capabilities are due to the uniqueness of ultrasonic flaw detection: the internal space of almost all structural materials can be “observed” by waves of a mechanical nature. Elastic waves, probing the metal, react to all the processes occurring in it, they perform the functions of a universal sensor that delivers information about the controlled environment. They allow to recognize an early stage of defect accumulation – micro damage formation, which is quite natural, since the parameters of elastic waves depend on the density, moduli of elasticity, size and geometry of structural inhomogeneities and other characteristics of the test medium.

Abstract During operation, aircraft (AC) are subject to use, maintenance, repair and disposal. Each of those processes requires adequate quality. This study presents requirements related to quality management with which an AC maintenance and repair sub-system ought to comply. Documents containing requirements pertaining to both management and technical aspects have been analysed. Applicable standards and regulations affecting the AC repair process quality assurance have been presented. A description of standards observance of which is required to ensure effective operation of modern AC maintenance and repair subsystems significantly affecting maintenance of the AC required airworthiness has been included. Complexity of the decision-taking process pertaining to AC maintenance and repair within the airworthiness maintenance sub-system has been presented

Near Future

Relatively low cost, easy to use, failure prediction technologies have empowered the maintenance department and have helped to change its position within plant organizational structures. Organizations that have embraced these new technologies and maintenance philosophies have helped to transform maintenance from a cost center into a strategically important department that has a material effect on profitability and competitiveness. As might be predicted, the rapid adoption of these failure prediction technologies is reducing the number of machines that are failing and having to be repaired. With fewer machines requiring repair, equipment repair shops are having to change to adapt to this new reality. In the near future fewer repair shops will exist and the ones that remain will be characterized as being high tech organizations with engineering, redesign and advanced repair process capabilities. These “repair shops of the future” will focus their energies on redesigning and then repairing chronically troublesome machines that have had the tendency to fail on a re-occurring basis. This paper will discuss these developments and show how they are reducing, and in some cases eliminating, the catastrophic failure of industrial plant machinery.

Concrete patch repair is becoming an important facet of the civil construction industry when considering the large quantity of exposed concrete surfaces requiring maintenance and rehabilitation during its design life cycle. Patch repairs are more often than not done with a specialized polymer-modified mortar which requires adequate quality control and quality assurance during application and curing to ensure long-term success. Unfortunately, there have been many patch repair projects where there has been poor performance of the patch repairs resulting in debonding, cracking and discolouration. In this paper, poor or inadequate quality control during the patch repair process is investigated as one of the possible reasons for poor performance and premature failure . It is postulated that because of the lack of adequate knowledge and understanding of the repair material and the repair process by the various stakeholders (applicator, supplier, consultant and client), deficiencies in the quality control and quality assurance before, during and after the repair project often exists. In many patch repair projects, the responsibility for the successful completion of the patch repair work and the assessment of long term performance of patch repairs is not fully embraced by all of the parties involved.This postulation has led to the research, by using questionnaires designed specifically for the four different stakeholder categories of the concrete repair industry. The results indicate that there is very little discussion amongst the stakeholders regarding quality control and acceptance criteria when performing concrete patch repairs, neither for the identification of patch repair failure directly after the completion of the patch repair, nor for long term performance of the patch repairs.

Introduction. Currently, there are no widely available technologies and equipment available at service stations and repair facilities to accurately assess the technical condition of Common Rail battery fuel supply system injectors. The methods implemented in practice mainly give a generalized assessment of the nozzle performance without identifying a specific defect, which entails an unjustified replacement of still working parts of electrically controlled injectors. The purpose of this article is to familiarize a wide range of specialists with a new non-slip test method for injectors with electronic control based on the evaluation of their fuel supply characteristics, which allows identifying specific malfunctions of the nozzle during the procedure of diagnostic without disassembling. Materials and Methods. The study is based on a systematic analysis of the factory methods for testing injectors, a review of modern scientific publications, the use of computer simulation in specialized programs, and experimental testing of the obtained results. Results. A method for testing and evaluating the technical condition of diesel injectors based on the fuel supply characteristics has been developed and tested that can significantly increase the information content of the diagnostic and reduce the overall labor intensity of repairing electronically controlled injectors by 24%. Discussion and Conclusion. The authors have developed and tested a measurement module and a test procedure for diesel injectors with the ability to assess the technical condition of their parts, which allows identifying and eliminating specific malfunctions of injectors without disassembling them and avoid unjustified replacement of serviceable elements during repair. The results of the study have been implemented in the Bosch Diesel Service fuel equipment repair center of Bashdiesel LLC.
