Straipsnyje autoriai analizuoja vandens gėlinimo mechanizmų, eksploatuojamų laive, tobulinimo galimybes atsižvelgiant į šių įrengimų sąveiką su jūros ekosistemomis ir nurūgštinimui naudojamų medžiagų galimą neigiamą poveikį šių ekosistemų veiklai bei siekiant sumažinti gėlinimo mechanizmų laive eksploatacinius kaštus. Atlikus eksperimentą, autoriai siūlo įdiegti modernų vandens laive nugėlinimo mechanizmą, nenaudojantį cheminių medžiagų, tačiau veikiantį ultragarsiniu dažniu taip padidinant finansinių išteklių naudojimo efektyvumą, sumažinant jūros ekosistemų taršą rūgštiniais chemikalais bei sumažinant grėsmę įgulos narių sveikatai.
Freshwater on board is needed to support vital functions of the crew and to ensure supply of freshwater used in ship maintenance processes, but in order to increase the sustainability and environmental friendliness of shipping, it is important to analyse the possibilities of modernization productivity of the engineering solutions that companies are providing. The object of research: the modernization of water desalination mechanisms on board. The aim of the research: to investigate the possibilities of modernization of water desalination mechanisms on board by reducing negative long-term impact on the environment. To achieve the research goal, three objectives are described: to analyse the principles of operation of the desalination mechanism operated on board and to investigate a possible case of modernization of fresh water generator. The research methodology is based on the analysis of scientific and technological literature and international maritime law documents, also on the engineering observation including the modelling method for the possible engineering solution application. The results of the study found out that existing desalination plates are subject to the formation of deposits, the removal of which uses acidic chemicals that pose a risk to marine ecosystems due to the contact with water and increase the cost of operating crew time. The possibilities of modernizing desalination engineering facilities by introducing a new generation of facilities based on certain principles can solve the problems and increase the sustainability of vessel processes.
