Turbine engine pdf


















It reveals that the diesel and the gas Midship Coefficient, CM 0. Service Speed [knots] It resulting plots of the investigation, these scenarios include: has also been recently contracted for the building of a number Calm weather conditions with a smooth ship hull surface of new frigates for the Royal Australian navy [9], as illustrated IWCs , Rough weather conditions with an assumed hull in a typical layout of its combine cycle configuration in Fig.

In addition to all these scenarios, the seasons of winter, spring and summer were also taken into consideration. Ambient Temperature and Sea State Data The thermodynamic cycle of the investigated marine gas Generally, the gas turbine is designed in such a way that turbine has been based on the configuration of the GE any deviation from the reference sea level international LM which is rated at an ISO power of 25 MW.

The optimal performance of the marine gas whereby at an installed shaft power of 25 MW, the turbine therefore is solely dependent on the local international standard atmospheric ISA conditions were environmental conditions prevailing at any geographical taken to be 15oC and Whenever there is an meteorological and hydrodynamic changes would significantly increase in the compressor inlet air temperature, it imposes a affect other vital engine operating parameters during the corresponding degradation in performance.

Wet compression voyage such as the compressor inlet air mass flow MF , the and water injection along with other techniques of component fuel flow FL , pressure ratio PR , and the engine firing or and machinery configurations are methods currently in place turbine entry temperature TET. A simulated result of The study has further revealed the effect of even SFC of African coast of the Atlantic Ocean and the Mediterranean C. It covers a total distance of nautical other specified parameters that describe the geometry of the miles when transiting at a speed of 22 knots via the Suez investigated vessel, as highlighted in TABLE II [11].

With a Canal for about 11 days of travel time [13]. An alternative displacement of over 1. Three units of the investigated economic benefits. Maritime security concerns around the marine gas turbine were determined to be sufficiently Horn of Africa together with the general insecurity situation adequate for meeting the installed capacity for both propulsion bordering on the Yemeni crisis [15] were observed as a major and the hotel load onboard the vessel.

It is typically designed to overcome a resistance in excess of 2. It is important to note that the installed power onboard the baseline vessel of the investigation takes 42 MW for propulsion, while the balance of 34 MW is dedicated for the hotel load, giving an installed plant power of 76 MW.

The Transit Route Profile Fig. A change became necessary when the by these environmental changes, the investigation was weather became unfavorable, as illustrated in Fig. Around the Mediterranean detected to have remained consistent at its designed speed of however, the minimum ambient temperature ranged between 22 knots throughout the voyage.

However, the encounter with 18 oC and 5 oC, while the compressor inlet air temperatures rough weather brought about by elevated sea states led to ranged between 18 oC and 28 oC on approaching the higher hydrodynamic resistance that resulted in increased destination port. During the summer periods and in contrast to power demand to sustain performance, as illustrated in Fig. The investigation further revealed how hot and cold weather A. Ship Navigation in Calm Weather conditions are geographically opposed to each other between An examination of how the changes in ambient conditions the tropical portion of the voyage and that of the affected the engine firing temperature under ideal weather Mediterranean Sea.

On the contrary during summer, investigated simple cycle marine gas turbine engine. The this same maximum temperature was maintained at a different research observed that the most unstable pattern of variation location in the Mediterranean but with a higher minimum took place during the spring season especially around the value of 1, K throughout the voyage.

Full load operation of tropical locations, but it later assumed a summer pattern the power plant in the spring season kept the TET at a modest towards the end of the voyage.

Other performance parameters maximum of 1, K and a minimum of 1, K. The results such as thermal efficiency, fuel mass flow, air mass flow and show how irregular operating conditions affect the ship power TET were also investigated, but a focus on the brake power plant during operations at full power.

Consequence of Hull Fouling the restriction induced by an increased resistance. It is a ship speed loss and increased travel times. This investigation phenomenon that potentially affects the operational efficiency has further revealed there is a fuel penalty with a higher fuel of the marine gas turbine power plant as it leads to increased consumption and greater emission of greenhouse gases along fuel consumption and the production and release of millions of with other emissions when a gas turbine-powered vessel is tons of greenhouse gases [16].

Peculiar cases of maritime route is recommended for further work. The fluctuations in power between The study may be further a 33 MW and 36 MW. The meteorological and hydrographic With the gas turbine in focus, the study has investigated the consequences of encountering different environmental possibility of undertaking a voyage by way of a cruise ship changes as well as a grossly fouled and poorly maintained carrying over 3, passengers and enjoying the full benefits submerged hull surface have been analyzed to show the fuel of 5-star hotel accommodation on board a passenger ship that consumption penalty resulting from it.

The extreme high is scheduled to last for a little over 10 days. Furthermore, this technology has the potential of easily being exploited to create extra accommodation or public spaces when installed on a cruise ship. Bonet; P. Bonet and P. Talluri, D.
