Marinfloc has started delivery of their combined EGR bleed-off and Bilge water separators for a major South Korean newbuilding project. To date, three of a total of twelve shipments for the 16,200 TEU methanol-powered vessels have been sent.
ABS, Lloyds, DNV and MAN Energy Solutions have approved Marinfloc’s innovative solution, which also complies with MEPC.107(49) and MEPC.307(73).
According to Marinfloc, all 12 vessels will be using a MAN B&W 8G95ME-C10.5-LGIM-EGRTC for methanol fuel and will be equipped with a Marinfloc CD5.0 EGR system to treat both the EGR bleed-off water and the bilge water.
The flocculation technology utilised by the Marinfloc’s treatment unit is effective in terms of both treatment efficiency and cost, regardless of the type of fuel utilised. The delivery is the first for methanol-fueled vessels but several units have been delivered to date with the first vessel in operation since early 2022.
As Marinfloc says, competitive both in Capital Expenditures (Capex) and Operating Expenditures (Opex) for EGR bleed-off and Bilge treatment Exhaust Gas Recirculation (EGR) is used to reduce NOx as per the Tier III requirements when used with compliant fuel. The EGR process will generate leed-off water that must be treated to <15 ppm, which is also the requirement for bilge water.
By combining the two treatment systems, the Capital Expenditures are significantly reduced – without any negative impact on performance. Additionally, there is also a reduction in Operating Expenditures as maintenance, spare parts and training are needed only for one unit.
The WhiteBox® is included as standard to segregate the waste streams, eliminate cross-contamination, and record all activities. Moreover, the WhiteBox® fulfills the EXXON requirements and is Marinfloc’s recommendation for all vessels calling the United States.
