ARE YOU READY FOR 2020?

WE ARE


ALTERNATIVES TO REDUCING NOX AND SOX


CHANGE TO MGO

Run full time on Marine Gas Oil

(MGO).

Convenient

Small investment

High operating cost

Future availability?

CONVERT TO LNG

Convert engines to run on gas

(LNG).

A solution which also reduces

NOx and particulates

Investment cost

LNG availability

USE Exhaust Gas Cleaning

Install an exhaust gas

cleaning system (scrubber).

Works with high S HFO

Lowest total lifecycle cost

Use everywhere

Easy operation

ROI depends on fuel oil price

difference between low S fuel oil

and high S HFO (scrubber)

FUEL SWITCH

Switch to low sulphur fuel in

SECA.

Flexible

Small investment

High operating cost in SECA

Fuel change over procedures

Lube oil TBN management

Fuel availability?

Short term solution

WÄRTSILÄ SCRUBBERS AND THE ENVIRONMENT

6

• Efficient scrubbing technology, removing both SOx and particulate matter

• Scrubbing changes SOx back into sulphates, which occur naturally in seawater

• Our tests show that we often get far below the set equivalent of 3,5%S down to 0,1%S.

Thus removing even more sulphur oxides than required by the rules.

• Better for the environment than MGO, as it saves energy (refinery) and removes some

black carbon (PM ≤ 2.5 µm)

• Water treatment units installed on all installations – even in Open loop

• Water treatment will ensure compliance even at tricky conditions e.g. start-up.

• Water treatment will ensure that harmful heavy metals (from the engine soot) will not

be released into the environment

Clean air

Clean ocean

Clean conscience


• Early experience on board Zaandam indicated that advanced open loop scrubbing water treatment was necessary, when problems with sheening arose.

• Problems with open loop water discharge will most often arise during start-up of the system, when a plume of particles will be going through the pipes. Without correct water treatment this will be discharged into the ocean and possibly lead to rule breaking.

• Wärtsilä is committed to following both current and future legislation, as well as providing the best and most environmentally sound technology for our customers.

SOLUTION FOR YOU

Open loop scrubber – sea water operations • Slightly higher power demand than CLS

• Does not need caustic soda

Applications: main alternative for ocean-going ships

Closed loop scrubber – 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 continued closed loop operation

Hybrid scrubbers – open loop / closed loop operations• Flexible system

• More complex system

Applications: ships requiring full flexibility of operations

WÄRTSILÄ SCRUBBER SYSTEMS

Two types of scrubber units: V-SOx and I-SOx. A full

portfolio to fit any vessel..
