Experience
Alfa Laval has more than 40 years of experience supplying scrubbers as an integrated part of inert gas systems (IGS) on board ships. During 2008, our experiences from these systems were used to design and test an exhaust gas cleaning system at the MAN Diesel (1 MW engine) test facilities in Denmark.
Installation on large Ro-Ro vessel
The knowledge and experience from these tests were successively used to design an entire PureSOx system on board DFDS’ Ro-Ro vessel “Ficaria Seaways”.
A modular and flexible exhaust gas scrubber design with a high degree of operational flexibility as well as future possibilities for upgrading the equipment has been chosen for the Ro-Ro vessel “Ficaria Seaways”.
Installed after the 21 MW MAN engine, it is by far the world’s largest exhaust gas cleaning system installed on board a ship. The design work has been carried out in close co-operation with the marine engineers from DFDS and MAN Diesel.
A comprehensive test scheme has been performed for a range of operating conditions to secure full compliance with the 2015 Marpol Annex VI legislation. MAN Diesel has participated intensively in the design work to ensure a smoot hand safe interface with the main engine.
Hybrid system
At open sea, PureSOx operates on seawater and in harbours and estuaries the system can operate on freshwater in a closed loop system without generating significant quantities of sludge to be handled at port calls.
PureSOx has been developed with a view on design upgrades for compliance with future legislation.
