Marinfloc EGR systems for methanol-fuelled boxships

Swedish wastewater treatment specialist, Marinfloc, is to supply combined exhaust gas recirculation (EGR) bleed-off and bilge water separators for twelve methanol-fuelled container ships under construction for Maersk Line. The 16,200-TEU ships are being built at Hyundai Heavy Industries in South Korea.

The vessels will have MAN B&W engines and Marinfloc CD5.0 EGR systems to treat both bleed-off and bilge water. The EGR process, which reduces NOx to comply with Tier III requirements, generates bleed-off water which, like bilge waste, must be treated to less than 15 parts per million. By combining the two systems, Marinfloc claims that savings can be achieved on capital costs, operating expenses, and maintenance. 

The system comes with the Marinfloc Whitebox® as standard. This contains monitoring and control equipment within a locked cabinet connected to a ship’s global positioning system (GPS). The digital setup monitors and records all relevant discharge data which can then be presented to regulatory authorities, including port state control and the US Coast Guard, as required.
