The article analyses the economic impact of compliance of the Lithuanian fleet with the new requirements of the MARPOL 73/78 Annex VI, which sets a limit for sulphur content in marine fuel to 0.1% in 2015 in Emission Control Area (ECA) and to 0.5% in 2020 globally. The assessment of several most realistic options of complying with the new requirements is presented in the article. Each of these methods is assessed by means of uncovering the economic and practical issues associated with applying their implementation to the Lithuanian fleet. An overview of Lithuanian fleet was carried out to choose the particular vessels for analysis. A group of 10 vessels was selected to compare the benefits and limitations of using low sulphur fuel and scrubbers. The economic impact of using low sulphur fuel or installing the scrubber for each vessel is also assessed in the article.

Abstract. The problematics of installation of sulphur oxides (SO x ) scrubber becomes much relevant for today due to the new Annex VI of MARPOL 73/78 requirements, which sets 0.1% SO x limits by 2015 in Emission Control Area (ECA) and globally to 0.5% in 2020. The research in this field becomes more significant for ship-owners. SO x scrubber is most promising alternative because of lower operating costs and suitability to existing ships. Despite the fact that exhausts gas scrubbing is a common and proven technology on land, the conditions on ships differ significantly and still there are not enough practical knowledge of installation of mentioned equipment. In addition, speaking about existing ships there are some limitation factors of SO x scrubber installation on-board, which will be discussed in the paper. Taking into account the size and mass of the SO x scrubber, it can be assumed that the recalculation of ship stability will be required for most ships. Therefore, the most important task for equipment designers is selection of scrubber system location with the minimum impact on ship stability and identification of necessary changes (deadweight, additional space, etc.) in accordance with ship safety requirements. For this reason, the research was carried-out in order to create the algorithm of ship stability assessment and selection of optimal scrubber location on-board.
The International Maritime Organization (IMO) through Annex VI of Marpol Convention sets 0.1% sulphur oxides (SO x) limits by 2015 in the Emission Control Area (ECA) and globally 0.5% by 2020. These restrictions will bring not only considerable financial problems but also technical challenges for shipowners. In order to comply with the said limits and achieve the best possible economic and technological results it is very important to make a well-founded decision both for existing ships and new ships in the conceptual design phase. According to ship characteristics, the design of a scrubber system will be determined by its operating profile. There is no way to avoid extra ship operation, administration and organisation costs no matter which solution will be chosen. Therefore, the most efficient solution in the context of a particular ship is of paramount importance. The article proposes a concept to be used for SO x scrubber system selection in the conceptual design phase, by analysing technical parameters, relevant to particular ship.
