The industrial Trent is the largest aeroderivative gas turbine available, at 50+ MW, and the most efficient gas turbine available to industrial and marine operators, at 42%. Its Dry Low Emissions combustion system embodies the features of the similar combustor on the industrial RB211, which is enjoying very successful service experience. Its design features and derivation from the aero engine are reviewed, together with an assessment of the maintenance aspects of the engine. The current status of the engine validation programme is discussed, covering both component rig testing and progress on the full engine testing being carried out in Montreal, Canada. The applications of the industrial Trent are considered by reviewing the major markets and examining its suitability, both technically and economically, for several existing and emerging sectors. Launched as a power generation machine, the industrial Trent is shown to be well suited to those sectors which have resulted from the growing deregulation of this industry worldwide. In addition it is shown to be attractive for certain applications in the oil and gas industry and, in the marine market, for some large high speed vessel concepts.

The Typhoon is a high thermal efficiency, low component count gas turbine originally launched into service in 1990. The single shaft version, used for power generation (C.H.P.), is rated at 4.1 MW ISO zero loss with a thermal efficiency of 32 per cent. At the date of writing, the Typhoon single shaft machines have accumulated 60,000 hours and 2,500 starts in service with very high levels of reliability. This paper describes the design of the two shaft version of the Typhoon, intended for operation primarily in the Oil and Gas Industry. The paper will concentrate on the “Concurrent Engineering” techniques used during the design process. The two shaft Typhoon will enter into service in 1994.

Emergency Power

In 1964 Kongsberg Våpenfabrikk AS decided to develop a small gas turbine for power generation, primarily for stand-by and emergency power. The engine was called the KG2 and had a unique all radial rotor design which was to become the trade mark for the later Kongsberg designs. The onset of the oil exploration in the Norwegian sector of the North Sea in the 1970’s gave the new business an opportunity to qualify for continuous drive applications and to expand into the international oil- and gas industry. In the following years a larger engine, the KG5, was launched and a third engine program was initiated, but never completed. The gas turbine know-how that was established in Kongsberg in these years was of great significance to the overall Norwegian gas turbine competence environment and was a deciding factor when Dresser-Rand first partnered with and later, in 1987, acquired the business. Under the new ownership the company became able to offer compressor- and power generation packages based on large aero-derivative gas turbines and it was soon recognized as a significant supplier, both nationally and internationally. The present paper provides a review of some of the unique design features of the KG series of engines as well as some of the typical applications. It also describes the transformation of the company from a small industrial gas turbine supplier to the recognized supplier of large, compressor- and power generation packages for the oil and gas industry.

Abstract In the oil and gas industry, manufacturers are continuously engaged in providing machines with improved performance, reliability and availability. First Stage Bucket is one of the most critical gas turbine components, bearing the brunt of very severe operating conditions in terms of high temperature and stresses; aeromechanic behavior is a key characteristic to be checked, to assure the absence of resonances that can lead to damage. Aim of this paper is to introduce a method for aeromechanical verification applied to the new First Stage Bucket for heavy duty MS5002 gas turbine with integrated cover plates. This target is achieved through a significantly cheaper and streamlined test (a rotating test bench facility, formally Wheel Box Test) in place of a full engine test. Scope of Wheel Box Test is the aeromechanical characterization for both Baseline and New bucket, in addition to the validation of the analytical models developed. Wheel Box Test is focused on the acquisition and visualization of dynamic data, simulating different forcing frequencies, and the measurement of natural frequencies, compared with the expected results. Moreover, a Finite Elements Model (FEM) tuning for frequency prediction is performed. Finally, the characterization of different types of dampers in terms of impact on frequencies and damping effect is carried out. Therefore, in line with response assessment and damping levels estimation, the most suitable damper is selected. The proposed approach could be extended for other machine models and for mechanical audits.

Abstract A gas turbine is a reliable type of rotating equipment, utilized in various applications. It is well known in power generation and aviation. In the oil and gas industry, gas turbines are utilized in locations with limited electrical power or a high power driven load requirement, such as offshore or a high-rated power 20MW compressor. Five gas turbines are used as mechanical drive equipment. After a few years of operation, the gas turbines were experiencing high operating temperatures in bearings, turbine compartments, high spread temperature, and the presence of smoke in the exhaust. During a major overhaul of the turbines, oil was found to have accumulated internally in the wrapper casing, along with damage to several internal combustion components. In one case, the exhaust casing experienced severe damage with deformation. This paper presents a case study of a gas turbine failure and its contributors. The paper explains the mitigated solution to overcome the challenges related to the gas turbine operation, maintenance, and machine design.

Abstract The API 20S Standard is designed to play a crucial role in leveraging Additive Manufacturing (AM) to foster innovation in the oil and gas industry. The paper, in association with the standard, will facilitate the understanding of how AM will enable equipment design improvements, faster prototyping, and better inventory management. By way of discussing the progress, challenges, and lessons learned from the standardization process, the paper aims to encourage a safer, broader, and faster adoption of AM technologies in the mainstream oil and gas applications. The paper will summarize the streamlining process, feedback from the API 20S task group, and current status of the standardization efforts. Additionally, upcoming challenges and the potential for the oil and gas industry industries to contribute to the standard will be summarized. The paper will also showcase a novel tiered approach (Additive Manufacturing Specification Levels) to allow the users of the document to match different levels of criticality.

Gas turbine driven centrifugal compressors are a mainstay in the oil and gas industry for upstream and midstream applications. For an increased effort to reduce greenhouse gases, one of the most promising efforts is the increase in operational efficiency. For the applications in the oil and gas industry, the efficiency increase come from increased equipment efficiency, or from increased operational efficiency. This paper is about increasing operational efficiency. The discussion will lead from the operational characteristics of gas turbine driven compressors to the characteristics of the application, and ways in planning and operation to optimize the system.
