| Abstract [eng] |
The dissertation investigates the issues of problematics of air pollution re-duction from ship propulsion. The main objects of research include technolo-gies of SOx emission reduction. The primary purpose of this dissertation is to create the basis of evaluotion of technological feasibility and economic effi-ciency of SOx emission reduction technology introduction and present the evaluation in the form of software. The scope of the software is the particular ship comparative analysis on pre-design phase, in order to select the optimal tehcnology to comply with MARPOL 73/78 Annex VI requirements. The dissertation approaches a few major tasks such as: the comparison of technologies of SOx reduction by demonstrating it’s introduction efficiency; the development of methodology basis of scrubber technology rational instal-lation onboard (the economic and technological aspects); performance evalu-ation of scrubber’s technology in order to ensure Lithuanian fleet compliance with the MARPOL 73/78 Annex VI requirements; studiesof experimental and mathematical modeling of scrubber introduction onboard. The dissertation consist introduction, 4 chapters, conclusions, referen-ces, the author’s publications on the dissertation topic and annexes. The introduction reveals the investigated problem and importance of the thesis. Chapter 1 revises problematics of air pollution from ship propulsion. It pro-vides: characteristics of ship exhausts emission; the development of regulatory of air pollution from ships; the analysis of technologies of air pollution reduction from ships. The chapter ends with conclusions and revised dissertation tasks. Chapter 2 presents methodological basis of the evaluation of SOx scrubber installation efficiency. Chapter 3 presents the methodological framework of realization prin-ciples of software and describes the mathematical modeling of adaptation of the methodology of Lithuanian fleet assessment. Chapter 4 presents results of the experimental research of scrubber system in operating mode. 11 articles focusing on the subject of the discussed dissertation are pub-lished: two article – in the Thomson ISI register, one article – in the journal quo-ted by Inspec data base, three articles – in conference material and scientific pa-pers in Thomson ISI data base, one article – in the scientific customize works, three articles – in material reviewed during international conferences and one article during an international seminar. 8 presentations on the subject have been given in conferences and seminars at national and international level. |
