  • Marinfloc delivers combined systems for methanol fuel container vessel projects in South Korea.
  • The EGR process will generate lead-off water that must be treated to <15 ppm, which is also the requirement for bilge water.
  • The WhiteBox is included as standard to segregate the waste streams, eliminate cross-contamination and record all activities. 

Marinfloc has begun delivering its combined EGR bleed-off and bilge water separators for a South Korean new building project, reported by Riviera.

Methanol-powered vehicle

To date, three of the 12 shipments for the 16,200-TEU methanol-powered vessels have been sent. 

ABS, LR, DNV and MAN Energy Solutions have approved Marinfloc’s solution, which also complies with MEPC.107(49) and MEPC.307(73).

All 12 vessels will use 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.

Marinfloc’s treatment

Marinfloc said in a statement, “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 company said the delivery is the first for methanol-fuelled vessels, but several units have been delivered to date with the first vessel in operation since early 2022.

It added, “Competitive both in capex and opex, the 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.”

EGR process

The EGR process will generate lead-off water that must be treated to <15 ppm, which is also the requirement for bilge water.

Marinfloc continued, “By combining the two treatment systems, capex is significantly reduced – without any negative impact on performance. 

Additionally, there is also a welcomed reduction in opex as maintenance, spare parts and training are needed only for one unit.”

The system is based on Marinfloc’s flocculation technology with thousands of references worldwide. 

The WhiteBox is included as standard to segregate the waste streams, eliminate cross-contamination and record all activities. 

The WhiteBox fulfills the EXXON requirements and is Marinfloc’s recommendation for all vessels calling at the US.
