East West

The 747-mile East-West Crude Oil Pipeline across Saudi Arabia employs 60 gas turbines for pumping and power generation. Mainline pump drives are three United Technologies Corporation FT4A-9 modular industrial gas turbines at each of 11 pumping stations. Two of the three mainline gas turbines are required for maximum throughput, while the third is an operational spare. High reliability and availability constraints and the remote unmanned station concept underscore the need for a modern maintenance information system. This paper describes an independent multiple-fault diagnostic/prognostic system, employing a patented gas path analysis technique.

Abstract Microgas turbine (MGT) engines in the range of 1–100 kW are playing a key role in distributed generation applications, due to the high reliability and quick load following that favor their integration with intermittent renewable sources. Micro-combined heat and power (CHP) systems based on gas turbine technology are obtaining a higher share in the market and are aiming at reducing the costs and increasing energy conversion efficiency. An effective control of system operating parameters during the whole engine lifetime is essential to maintain desired performance and at the same time guarantee safe operations. Because of the necessity to reduce the costs, fewer sensors are usually available than in standard industrial gas turbines, limiting the choice of control parameters. This aspect is aggravated by engine aging and deterioration phenomena that change operating performance from the expected one. In this situation, a control architecture designed for healthy operations may not be adequate anymore, because the relationship between measured parameters and unmeasured variables (e.g., turbine inlet temperature (TIT) or efficiency) varies depending on the level of engine deterioration. In this work, an adaptive control scheme is proposed to compensate the effects of engine degradation over the lifetime. Component degradation level is monitored by a diagnostic tool that estimates performance variations from the available measurements; then, the information on the gas turbine health condition is used by an observer-based model predictive controller to maintain the machine in a safe range of operation and limit the reduction in system efficiency.

This paper describes the application of gas turbines to crude-oil production in a Venezuelan underwater reservoir. Decreasing pressure caused a gradual slowing down of the natural flow, and Creole Corporation was faced with the problem of either artificial lifting of the crude or curtailment of operations with several years of ample supply remaining untapped. This challenge was met successfully through repressurization of the wells by gas turbines. The design of these turbine facilities, their operation, and some of the problems involved are described. The author summarizes with a review of the performance of the gas turbines at their various locations.

Industrial gas turbines utilize numerous design features that cannot be implemented in jet aircraft turbines for weight reasons, but because of their straight-forward and robust nature trim costs and reduce both maintenance effort and operating risks. Regardless of manufacturer, the following design features, for example, have become the established industry standard: • single-shaft rotor; • 2 bearings at atmospheric pressure; • Journal bearing instead of ball bearings; • steel blading in the compressor. For the key components compressor, turbine, rotor, and combustion chamber of its 3A family (Fig. 1), Siemens has developed and tested additional features that reduce wear further and improve operational reliability. Operating experience gathered to date has shown that these features enable achievements of very high reliability and availability. Some of the measures described also contribute to enhanced output and efficiency.

The paper presents an overview of the system employed to control the mainline gas turbines and crude oil pumps used on the 747 mile East-West Petroline. Various operating modes such as starting, stopping and fuel transfers for normal and emergency operation are discussed. Particular attention is focused on the various fuel systems as well as a review of the major design problem areas and solutions. The results of a system test and the integration of each unit into the overall pipeline control scheme are included for completeness.

And Control

Trans-Arabian Pipe Line Company and the Arabian American Oil Company have installed a group of portable auxiliary pumping units at intermediate locations on the crude-oil pipeline across Arabia to the Mediterranean. The units are powered by 5000-hp General Electric gas turbines burning crude oil for fuel and are controlled by radio from upstream pump stations. Operating experience between 1957 and September 1959 indicates that the design promise of 80 per cent operating factor was conservative. Intensive effort has been applied to overcome mechanical faults, crude-oil combustion problems, and control instability. Major problems are discussed in detail with a description of the methods and facilities used to reduce the effect on operating reliability and maintenance expense. The paper briefly discusses development work now in progress which is expected to smooth out seasonal capacity fluctuations and possibly result in a substantial increase over design rating. Since much of the development work is still in progress, it is the intent of this paper to review the operation of the subject pumping units to date. It is intended that a paper to follow this one at a future date will report in more detail the operating experience as a result of the work now being done.

For more than a decade, aircraft-derivative industrial gas turbines have been used in middle eastern oil fields for providing power to water injection and crude oil pumping installations. The remote desert locations and the hostile environment provide a unique challenge. This paper describes some of the experiences gained in operating aero-derivative gas turbines in the onshore oil fields of Abu Dhabi.

The predominant role of large gas turbines has shifted from peaking-load duty to midrange and base-load electric power generation, especially within combined-cycle plants. Such applications require heavy-duty industrial gas turbines to ensure the same high reliability and availability for continuous service as the associated steam turbines. It is also important that the gas turbines be designed for low maintenance to minimize the necessary outage times and costs for component repair and replacement. The basic design principles and applications of Model V94 gas turbines are discussed with special reference to highly reliable and economic bulk power generation.

This paper presents the most important problems which have to be expected when burning residuals and crudes in industrial gas turbines. Solutions for these problems are always influencing the operating costs of the powerplant. Careful economical studies should, therefore, be conducted before one or another fuel is selected. Finally, operating experiences with 14 BBC gas turbines located in Riyadh (Kingdom of Saudiarabia) burning local Khurais crude oil with turbine inlet temperatures of 650 to 850 C are presented.
