On-board Energy systems in vessels have to use fuel efficiently to maintain ship speed at lowest possible costs. This paper describes how to use ship operational data to improve and maintain efficiency of the vessel’s power production with respect to the condition and performance of equipment. The paper describes an overview of an automated Technical Operations Performance (TOP) Monitoring service. TOP monitors the performance of marine main and auxiliary diesel engines by use of the information collected onboard vessels at regular intervals. Performance data are stored in xml-reports sent as email attachments from ship to shore. This communication is reliable and cost efficient for merchant ships that are on-line only for shorter periods. Load, ISO and environmental corrections make results valid for benchmarking and trending. The service aggregates the hierarchical information obtained from different sources by transferring measurement readings into unified indicators, the Technical Condition Index (TCI) [1]. Experts manually check the automatically generated performance reports and add additional guidance on options to improve power production and machinery conditions analyzing the available data with respect to different targets, such as low engine degradation and high fuel efficiency. The performance reports then influence business processes indicating possible causes for loss of performance in equipment and possible erroneous instrumentation, and the need for maintenance actions. The obtained TCI values show the performance of individual units, or for a fleet/class of equipment and vessels.

Steam Production

The concept of solar steam production for injection in a gas turbine combustion chamber is studied for both nominal and part load engine operation. First, a 5MW single shaft engine is considered which is then retrofitted for solar steam injection using either a tower receiver or a parabolic troughs scheme. Next, solar thermal power is used to augment steam production of an already steam injected single shaft engine without any modification of the existing HRSG by placing the solar receiver/evaporator in parallel with the conventional one. For the case examined in this paper, solar steam injection results to an increase of annual power production (∼15%) and annual fuel efficiency (∼6%) compared to the fuel-only engine. It is also shown that the tower receiver scheme has a more stable behavior throughout the year compared to the troughs scheme that has better performance at summer than at winter. In the case of doubling the steam-to-air ratio of an already steam injected gas turbine through the use of a solar evaporator, annual power production and fuel efficiency increase by 5% and 2% respectively.

Development and practical implementation of the enterprise industrial safety management system considering the new requirements of the legislation on creation of the state system for monitoring, remote control, technical certification, and diagnostics of technical devices at hazardous production facilities supervised by Rostechnadzor is discussed in the article. To perform automated collection, recording, generalization, systematization, and evaluation of the information on the parameters that characterize safety of the enterprise hazardous equipment as a whole and each technical device, a block diagram of the enterprise automated industrial safety management system is proposed. The basics are suggested for creating the automated system containing a database that includes all the technical documentation, certificates and expert opinions, repair documentation and accompanying documents (orders, instructions, audit conclusions, etc.) for the efficiency of tracking the technical condition in real time considering changes in all the controlled parameters of the enterprise technological complexes. It is noted in the article that the assessment of the technical condition and life of single and unique technical devices that make up the bulk of equipment in hazardous production should be carried out already at the manufacturing stage by combining technical control with technical diagnostics, and their results should be included in the technical passport of the device. The need in this information for the operators is invaluable, especially after working out the manufacturer’s designated period of safe operation and for evaluating the actual technical condition and comparing it with its original, which was documented during fabrication. Data on the initial state allows to qualitatively assess the degradation processes that are developing during operation and consider them when evaluating the life of a technical device and conduct a qualitative audit of the industrial safety management system.

Relevance of the work. The operational efficiency and technical condition of mining vehicles to a large extent depend on the service life and performance characteristics of tires. The most important technological process that determines the effectiveness of field development is the transportation of rock mass. The share of motor transport costs in the total cost and production by open method at Russian mining enterprises is significant, and reaches 70% as the depth of open pits (cuts) increases. At the same time, the actual productivity of mining trucks is much lower than their technical and technological capabilities, and this difference is up to 2.5 times or more for various brands of vehicles, including imported ones. Today, both consumers and manufacturers of large tires are interested in the most efficient tire production management. Purpose of the work: consideration of the main factors affecting tyre life, as well as datum ranking of these factors to determine the degree of significance of each factor. Methodology of research. The systematic approach was used including datum ranking method, some analytical, computational methods and generalization. Results. The ranking was carried out by three independent groups of experts on a number of proposed factors. The main factors in each group were identified and the degree of agreement between the opinions of the interviewed specialists was evaluated. The general opinion of various expert groups on the significance and ranking of factors affecting the integrity of giant tires is confirmed. Conclusions. Datum ranking and analysis of factors affecting the wear of giant tires of mining dump trucks significantly affect the optimization of machine operation and, with appropriate adjustments, can give a positive economic effect.

Two phenomena are having a profound effect on management and industry in the 21st century. The first one is the increasing rate and depth of competition locally, regionally, and globally, and the consequent increase in focus on achieving competitiveness by companies. The second phenomenon is the increasing appreciation of the importance of employees in assisting the company to gain a competitive advantage over its competitors. Employee Assistance Programmes have been used as part of the business strategy to enhance employee functioning, loyalty, and performance in organisations around the world for a good part of the 20th century. In South Africa this service did not gain much momentum until the 1980. Despite the growth of EAP in South Africa, however, in most cases it still remains on the periphery of real business activities and is often regarded as a "nice to have" rather than as a business imperative. The location of EAP within a company is very important in determining its impact within the organisation. Because of EAPs capacity to impact on both individual employees and the organisation as its primary client, it has potential to make a great impact in organisations' business processes, where these interface with individual output and wellbeing. A service-profit-chain model was introduced as a link between employee satisfaction and company profitability. This article gives an in-depth focus on EAP and the important role it can play in achieving employee satisfaction.

The Supply Chain Improvement (SCO) project is being introduced by KNPC, which recognises the major business advantages of improved hydrocarbon supply chain efficiency. The objectives of this work is to strengthen, optimise, and integrate supply scheduling and processes not just at stage of enterprise, but also throughout the entire KNPC framework. This is expected to lead to an improvement in the company's bottom line and facilitate the management of business operations at the highest level of efficiency, agility and profitability. In ever changing market conditions and globally competitiveness, it is necessary that raw material supply storage and product delivery were carried out at the lowest possible time and efficiency. Otherwise export oriented refinery like KNPC cannot remain in business with profit. KNPC has therefore embarked on ambitious multi-year operational excellence programs aimed at enhancing its operations and business processes that include short / mid-term planning, scheduling, accounting for growth, inventory management, and performance management. The aim is to achieve top-quartile financial results by accessing new value streams, encapsulating business processes of best practice and motivating employees of businesses to work in a collaborative atmosphere within the global and cross-functional business cycle to make smarter, quicker and more competitive choices.
