The purpose of this thesis is to examine the methods of reducing sulfur oxide (Sox) emissions in
shipping through exhaust gas cleaning systems but mainly with wet scrubbers. The various types
of exhaust gas scrubber systems for reducing sulfur dioxide (Sox) emissions in marine combustion
engines are analyzed with emphasis in open loop seawater scrubbers. The advantages,
disadvantages and technical and environmental limitations governing the operation of each system
are presented. In addition, a comparison and evaluation report is made for each EGCS system, and
which one best fit each type of ship. An economic evaluation has also been made for the EGCS
systems, indicating the investment cost (CAPEX) and the time required for the amortization of the
system, which naturally varies depending on the prevailing fuel prices in shipping industry and
how often the system is used by the ship. In addition to the theoretical part of the research, the
work also includes a practical approach required for the maintenance of open-loop sulfur oxide
(Sox) scrubbers based on practical data and observations from real operating conditions on board
the ship.
