Samenvatting

This document has been prepared to advise vessel owners and charterers about the fuel sulphur reduction options and implications regarding to the introduction of 0.10% m/m sulphur distillate in the ECA's from 1 January 2015. There are also general sections to provide information on legislation and information about the several systems.
IMO MARPOL Annex VI provides the legislative framework for fuel sulphur reductions and the associated timing. The relevant parts of this legislation are in the document and the implications of the changes are analysed.
During this research the specific precautions which CFL can take to protect our environment from air pollution caused by the use of sulphur containing fuel oils will be the central matter. Because of the tightening-up of the sulphur regulations and the expansion of the ECA's, the company CFL likes to determine if the installation of a scrubber is a possible and a dignified alternative. The determination will be done during this research out of a technical and financial approach. This leads us to the research question of this paper:
"Is it possible and economical to install a scrubber onboard of the vessel type 'Sole 10.000' to comply with the SOx regulations whilst using HFO?"
The well found answer to this question follows after discussing and analyzing the technical and economic considerations. Retrofitting the complete scrubber installation into the vessels original body is not possible. Even after a conversion of the exhaust gas casing to fit the scrubbing tower, there is still not enough place available to install the auxiliary equipment of the exhaust gas cleaning system. From a technical point of view it is not feasible to install the scrubber installation onboard of a Sole 10.000.
The payback period of the scrubber is primarily sensitive to the price spread between HFO and MGO and not less sensitive to CAPEX and the absolute HFO price. 100% and 50% ECA operation give a payback period of respectively four and seven years, assuming an HFO-MGO spread of 176 USD/ton.
For the vessel type Sole 10.000 with 5% (maximum 10% (CFL)) ECA operation nowadays, the payback periods will be very long, and the most favorable for CFL from an economical point of view will be to switch to MGO when operating in an ECA. With an ECA operation of more than 90% and depending on the remaining commercial lifetime of the vessel, it is recommended to CFL to search for a similar alternative as the scrubber installation but which has an applicable footprint and a more attractive economical profile.
As the scope of this research is limited to scrubber installations, there is no detailed information provided for operation on LNG or other gaseous fuels.
