Wärtsilä Marine Scrubber Portfolio

Open loop scrubber – sea water operations

• Uses seawater i.e. no freshwater needs

• Slightly higher power demand than FWS

• Does not need caustic soda

• Applications: main alternative for ocean-going ships

Closed loop scrubber – fresh water/closed loop operations

• Independent on seawater alkalinity

• Zero effluent discharge an option

• Low power demand

• Needs caustic soda as a reagent

• Applications: seas with extremely low alkalinity and for operators looking for continuous closed loop operation

Hybrid scrubbers – open loop / closed loop operations

• Flexible system

• More complex system

• Applications: ships requiring full flexibility of operations

Inline vs conventional scrubber

Inline scrubber Conventional scrubber

Wash water amount 55 m3/MWh 45 m3/MWh

Max fuel S% content in open loop 2,5% 3,5%

PM removal No Up to 85%

Benefits inline scrubber:

• Smaller footprint and operational flexibility• The main stream configuration provides good redundancy• No by-pass and simple installation

Reference inline scrubber• First installation: Color Line Super Speed 2 in operation • Similar installations for 3 other Color Line vessels• 11 Inline scrubbers (hybrid) ordered for cruise vessels • 4 Inline scrubbers (closed loop) ordered for two RoRo vessel

Sulphur oxides SOx in sea water (scrubbing process) forms sulphuric acid – low pH

Sea water alkalinityneutralizes the pH – rest “product” from scrubbing is sulphate

Sulphate is a natural substance in sea water - approximate amount: 2 700 mg/l

Water treatment and sludge

To be disposed of ashore

Estimated amount:Closed loop: 1,0 kg/MWh Open loop: 0,05 kg/MWh

The amount depends on silt content in water and engine running profile

All Wärtsilä scrubber systems have water treatment included as a default. The goal is to always follow current and future legislation, guaranteeing

compliance for our customer.

Based upon our investigations we needed to find an EGC system with scrubbers that could be fitted into the existing engine casing ColorLine

ColorLine SuperSpeed II:

• Operates 100% within SECA

• 4 x 9,45MW Wärtsilä

• Space limitations in funnel

• Wärtsilä Inline Scrubber installation
