    Evaluation of the Performance Characteristics of a Gas Turbine
    (Lambert Academic Publishing, 2017-04-25) Emughiphel Nelson Igoma
    This work focuses on using pertinent performance parameters to evaluate the performance characteristics of the Trans-Amadi gas turbine power station Phase II. The investigation took thirteen (13) months (January 2012 to January 2013) during which direct measurements were made and operational Logsheets like turbine logsheets, plant – auxiliaries’ logsheets and generator logsheets were studied. The gas turbine (GT) that was under investigation was GT-2: MS5001 Nuovopignone with designed installed capacity of 25.0 Meggawatts (MW).The result of the study shows that a 10C rise of the ambient temperature or compressor inlet temperature is responsible for the following: 0 – 0.12% decrease in the power output, 0 – 0.12% increase in the power differential, 0 – 1.17% decrease in the thermal efficiency, 0 –27.18% decrease in the heat rate and 0 –3.57% increase in the specific fuel consumption. The thermal efficiency decreases as the heat rate increases. The average of the performance parameters like thermal efficiency (24.19%), work ratio (0.855), thermal discharge index (3.13), net plant heat rate (14.90MJ/KW) and net work ratio (0.30) were computed as indicated and they proved in comparison with their respective design values(26.6% 0.4-0.8,3.42, 10-20MJ/KW and 0.25) significant correspondence.

    ASSESSMENT OF THE CAUSES OF SHIP GENERATED MARINE POLLUTION IN NIGERIA COASTAL WATERWAY
    (INTERNATIONAL JOURNAL OF MARITIME AND INTERDISCIPLINARY RESEARCH (IJMIR), 2021-03-26) Emughiphel Nelson Igoma
    The assessment of the causes of ship generated marine pollution in Nigeria coastal waterways has been studied utilizing a dependable questionnaire data - based approach. These questions were distributed to some key industry personnel who have cognition about marine pollution doubled with those who are working in the maritime related industries. After the survey- like questions distributions and collections, tabulation of the hypothetical response were used for the appraisal of the results. In each of the tabulation, seven questions were raised and sixty respondents were required to complete it. The respondent employment details coupled with some vital personal bio data were also required. And the percentage of each of the respondents was collated and tabulated. The result obtained from dependable Excel Software Program analysis shows that the issue discussed is true. Therefore, the need for proper implementation of the IMO laws enacted at the respective conventions for various classes of marine pollutions is needed.

    Evaluation of the Influence of Ambient Temperature on the Performance of the Trans-Amadi Gas Turbine Plant
    (Journal of Power and Energy Engineering, 2016-11-24) Emughiphel Nelson Igoma
    This paper examines the effects of ambient temperature on the Trans-Amadi gas turbine power station Phase II. The investigation took thirteen (13) months (January 2012 to January 2013) during which plant data were monitored and operational Logsheets like turbine logsheets, plant—auxiliaries’ logsheets and generator logsheets were studied. The gas turbine (GT) that was under investigation was GT-2: MS5001 Nuovopignone with designed installed capacity of 25.0 Megawatts (MW). The result of the study shows that a 1˚C rise of the ambient temperature is responsible for the following: 0% - 0.12% decrease in the power output, 0% - 0.12% increase in the pow er differential, 0% - 1.17% decrease in the thermal efficiency, 0% - 27.18% increase in the heat rate and 0% - 3.57% increase in the specific fuel consumption. An ambient temperature of 30˚C is found to yield minimal fuel consumption.

    Performance Improvement of Water Supply from Kurutie Community Distribution Station to Nigeria Maritime University, Okerenkoko, Kurutie - Takeoff Campus
    (International Journal Of Engineering Research And Development, 2025-03-31) Otuaro Ebierin Akpoebidimiyen and Igoma, Emughiphel Nelson
    The performance improvement of water supply from Kurutie community distribution station to Nigeria maritime university, Okerenkoko, Kurutie - takeoff campus has been done. The study area is the Kurutie Community in the Gbaramatu Kingdom in the Warri South West Local Government Area of Delta State, Nigeria. The assessed population is less than 5000 in 2024. The techniques adopted for the performance improvement are condition evaluation like inspection of the constituents of the distribution system, such as pumping stations, reservoirs, transmission and treatment plants and valves and the EPANET was used for the design of the layout of the distribution network; pressure – volume assessment, customer feedback together with performance ratings. The SPEM was used to evaluate the onsite, physical together with visual inspection of the constituents in the distribution system and the pump station physical condition and performance rating; physical condition and performance assessment of the industrial filters; physical condition and performance rating of the pipes; physical condition and performance rating of the valves; physical condition and performance assessment of the reservoirs and pressure-volume and supply duration assessment respectively. Finally, the consumers’ feedback shows that water distribution is not enough, and it is epileptic, and a proposed design of a water distribution system has been done utilizing EPANET. It is recommended that routine maintenance for the distribution of the system should be corrective and preventative and not breakdown maintenance and the SPEM advises that much staff should be employed in the distribution system for efficient operation.

    Comparative Analysis of Different Boreholes Water Qualities in Kurutie and Kunukunuma Communities
    (2025-03-31) Otuaro Ebierin Akpoebidimiyen and Igoma, Emughiphel Nelson
    The comparative analyses of different boreholes water qualities in Kurutie and Kunukunuma communities have been done. The two boreholes' water was bottled in two separate bottles of 100cl cans and labelled Sample A and Sample B, and they were preserved in a cool place before it was transported to the laboratory for physical, chemical and biological analysis. The laboratory experiments carried out are pH, BOD5, TDS, DO, Nitrate, Turbidity and Hardness respectively. The results of the experiment show that the borehole water of Kurutie has pH – 8.2, DO – 3.6mg/L, BOD5 – 2.3mg/L, Conductivity - 417 µS/cm, TDS – 208mg/L, Nitrate – 0.4mg/L, Turbidity – 3.0NTU and water hardness of 202.3mg/L . While that of the Kunukunuma borehole water contains pH – 7.1, DO The water of borehole has become not appropriate for household utilization as a result of contaminants that makes it not proper for different usages (Agbaire & Oyibo, 2009). The purpose of assessing the quality of water is to avert health perils linked to the usage of water directly or indirectly, and the standard, together with the regulations for water quality, arises as a result of the necessity for the protection of human beings' health (Udom et al., 2002; Minh et al., 2011). – 3.0mg/L, BOD5 – 1.9mg/L, Conductivity - 341 µS/cm, TDS – 171mg/L, Nitrate – 24mg/L, Turbidity – 13NTU and water hardness of 122mg/L respectively. The results were compared to the WHO standard, and they are in agreement except for the water hardness of Kurutie borehole water, which is about 2.3mg/L higher. It was recommended that water treatment should be done on Kurutie water to reduce the water hardness because other studies have also proved these results to be true.
