Given the maturity of the gas turbine user industry, and the quality of the original equipment manufactured, the field experience of these machines has been broadly very good. Nonetheless, there can be difficulties in managing availability and reliability, and the costs of unscheduled shut downs can be extremely large. Advanced gas turbine performance management offers opportunities in improving availability, reliability and productivity, driving down life cycle costs as well as adding to safety and compliance. This paper describes in detail the development of an engine fault diagnostics tool by the authors. The authors focus on structure, functionality as well as possible benefits of its use. The first part describes the structure and various methodologies adopted in the development of the system and the second part of the work describes the system and its salient features. The primary goal at this point of time was to test the utility, functionality and robustness of the presented tool, interesting and relevant results are obtained. Due to space limitations we restrict ourselves to discussing the system and not go into the details of actual simulation runs.

In view of the increasing demands from stakeholders (patients, management, insurance companies, media, etc.) to ensure the quality of health care and the implementation of the program of state guarantees in the current difficult conditions of increasing importance is the efficient and performance management of medical organisation (MO). As part of these requirements has been widely discussed question of the necessity of building a system of quality management MO. Practical experience shows that building a systematic approach to quality management depends primarily on the availability of managerial competencies for managers and heads of departments MO, as well as their level of motivation, or resistance to organizational change. One of the tested and proved to be a reliable tool in the management of the quality of medical practice is a process approach. With this management tool, it is possible to present the activities of MO as a chain of interrelated processes. It defines the criteria for the quality of the product, the necessary resource and regulatory support, introduces the institute of internal and external customer, which ultimately has a positive effect on the performance indicators and efficiency MO.

A study was made of 526 advanced coal-fired locomotive concepts of which 182 used gas turbine engines. This paper summarizes the results of the gas turbine portion of the study. Fifteen forms of coal including coal derived liquids, 15 different combustors, and five types of gas turbine engines were investigated. The principal means of comparing the different engines is by their life-cycle costs. The reason for this approach is that the greatest attraction of coal-fired locomotives is their low operating costs relative to that of Diesel-electric locomotives now in use. Many of the coal-fired locomotives have half the life-cycle costs of comparable Diesel-electrics. Although the analysis was made for conditions in the United States, the results are applicable to other countries.

The Rolls-Royce Allison (RRA) 501-K34 serves as the prime mover for the Ship Service Gas Turbine Generator sets (SSGTGs) of the U.S. Navy’s DDG-51 Class ships. Navy experience with the 501-K34 began in 1988 with the testing of the first prototype. Experience to date includes over 700,000 fired hours on a growing fleet of engines. This paper explores that operating experience and discusses future plans to improve the engine’s operational availability while lowering life cycle costs.

Steam Plant

Heavy-duty industrial gas turbines are suggested as an alternative propulsion plant to consider for ships, particularly ships of large displacement that are not volume limited. This paper examines the use of such a plant in a naval auxiliary, the Fast Combat Support Ship (AOE-1, Sacramento Class). The cycle discussed is of the combined gas turbine and steam cycle. The inlet to the compressor is supercharged and then intercooled, allowing the gas turbine to perform at significantly higher than rated power levels. Two controllable-pitch propellers at 50,000 shp each are used to drive the ship. Exhaust from the turbine is used to generate steam in an unfired waste-heat boiler. Reliability, maintainability, life-cycle costs and manning are addressed for comparison with the presently installed steam plant.

The Difference

In the increasingly competitive global marketplace the users of industrial products face the challenge of predicting accurate life-cycle costs of their equipment and machinery. The deregulation of many industries resulted in inability of operating companies to pass over to the customer the increased costs of their products, which may have been caused by inaccurate predictions of the equipment operating costs. This evolution in the 1980’s have emphasized the need for accurate predictions of the equipment operating costs and have meant the difference between profit and loss. This paper presents the concept of equipment Durability to be used in the process of evaluation the equipment life cycle cost and subsequent equipment selection. It is also the first part or primer to the paper which describes the Durability Surveillance Program on the Advanced Gas Turbines sponsored by EPRI titled “Durability Surveillance Program on the Advanced Gas Turbine GE Frame 7 F” (1).

Gas Turbine Generator Sets (GTGs) provide electrical power for the U.S. Navy’s DDG-51 Class ships. These GTGs, packaged by Rolls Royce and powered by the Rolls Royce 501-K34, have been the subject of substantial, well-documented improvement efforts. This paper discusses the processes used to evaluate reliability and identify problematic components. It describes corrective actions that have been made to date and lays out a plan for the future. It goes on to discuss the impact that each improvement has made to GTG reliability and life cycle costs while attempting to project future impact.

Required Quality

In construction production, the safety of constructing buildings and structures is achieved by ensuring the required quality as a result of systematic construction control based on the implementation of a complex of technical, economic and organizational measures at all stages of the object's life cycle. The article deals with the actual problem of improving the quality of construction products-buildings and structures in conjunction with the activities of construction control bodies. The article presents the advanced foreign and domestic experience of ensuring the quality control at the construction sites, providing for the prevention of the underlying causes of defects and increasing the interest of the contractors directly. On the basis of the analysis of the current situation with quality control at the construction market, ways to improve its efficiency by developing a unified system of technological implementation of relevant requirements for the quality of construction products, determining the rational number and business load of construction control engineers, as well as the active activities of self-regulatory organizations in this area are offered.
