Marinfloc Delivers Combined Systems For Major Methanol Fuel Container Vessels Project In South Korea

Marinfloc has initiated 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).

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 utilized by the Marinfloc’s treatment unit is effective in terms of both treatment efficiency and cost, regardless of the type of fuel utilized. 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.

Competitive both in Capex and 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 welcomed reduction in Operating Expenditures as maintenance, spare parts and training are needed only for one unit.

The system is based on Marinfloc’s well-known flocculation technology with thousands of references worldwide. The WhiteBox® is included as standard to segregate the waste streams, eliminates cross-contamination, and record all activities. Moreover, the WhiteBox® fulfils the EXXON requirements and is Marinfloc’s recommendation for all vessels calling the US.
