YOUR BEST CHOICE FOR EXHAUST GAS CLEANING SYSTEM
Α system that cover all your needs
Clean Marine solution is proven to connect all of the ship’s exhaust streams, including the boilers, to one single scrubber unit, without encountering an increase in back pressure to the engines and boilers. That’s why Clean Marine EGCS is a unique Allstream system: all exhaust sources (boilers included) are served by one common EGC unit without any additional back pressure. This makes it a cost-efficient option for vessels with multiple exhaust sources, as the oe EGCS unit simultaneously serve several combustion units.
Main product features
Main engines, aux. engines and boilers are all served by one single scrubbing unit without any backpressure.
This is achieved by two fans and a unique gas recirculation device.
- Two fans with capacity in excess of exhaust production prevents pressure to build up.
- An open nozzle ring allows gas to pass between raw gas and clean gas side.
- The combined effect of fans and nozzle ring ensure that pressure in manifold is +/- 0
- Pressure detector in manifold activate bypass if exceeding preset values
Exceptional Open Loop system that enables vessels to transit from high to low alkalinity and salinity water without loss of SOx cleaning efficiency
The system can be designed to run in zero-discharge mode (closed loop) to cater for potential restrictions in certain ports and areas. The holding tank will store the process water and is dimensioned for the ship’s required ﬂexibility.
Tamper-free analyzer is continuously monitoring the SO2/CO2 ratio and compliance is logged together with GPS position of the vessel.
5.Trapping Sox & particles
The patented wet Advanced Vortex Chamber” is combined
with two powerful fans to achieve outstanding trapping efficiency for Sulphur (SOx) as well as soot and ash particles (PM-Particulate Matter).
NO BACK PRESSURE TO THE ENGINES AND BOILERS
Moreover, recognizing that the IMO sulphur requirement reflects a demand to minimize human exposure to harmful Particulate Matter (PM), a unique PM trapping feature surpassing the present sulphur requirement has been incorporated into the scrubber.
Easy Το Install : Back Pack Solution
The basic idea
Install an all stream semi hybrid EGCS at minimum off-hire and interference with existing ship structure.
The concept is designed to fit any cargo ships with a separate engine casing and funnel structure. The EGC unit will be preinstalled in a “back pack” structure ready to be lifted onboard at installation site. The all stream feature is provided by installing a common exhaust collector box fabricated in black steel and designed according to the existing structure and up stream exhaust lines. The fans being part of the EGC unit then eliminate any back pressure issues. The system will have a boosting feature allowing NaOH to be injected in open loop mode allowing the vessel to trade into any water while also meeting the strictest pH requirements (US VGP). Later conversion to closed loop operation is easily done by allocating holding tank space to the ready system design.
The concept is applicable for existing ships as a EGCS retrofit solution. But it is also a convenient basis for amendment of new building designs as there little interference with existing machinery.
Time to meet the Emission Control Regulations
The International Maritime Organization (IMO) Annex VI Sulphur regulation called for a 0.1% Sulphur limit in Emission Control Areas (ECA) from 2015 and a worldwide 0.5% limit will be introduced in 2020.
Current ECA include the Baltic Sea, North Sea, English Channel, US and Canadian coasts and inland waters, as well as parts of the Caribbean Sea, while Mediterranean area is proposed to be also included in the list. However, a worldwide limit of 0.5% will be implemented by 2020.
Shipping Companies have only three options to meet the upcoming regulations:
1.Use the more expensive distillate fuel with 0.1/0.5% sulfur content
2. Convert to new fuel types (e.g. LNG), option which is risky and costly.
3. Continue operation on the heavy fuel oil HFO) and install an EGCS, to remove 98% of the sulfur from the exhaust gas.
What we recommend
Since the most existing vessels are powered by heavy fuel oil, scrubber technology has proven to be the most effective and commercially viable solution.
The installation of an exhaust gas cleaning system is the most cost effective solution to meet the IMO Sulphur regulations, and most vessels trading more than 50% inside ECA will see a payback time of only 1-3 years if investing in a Clean Marine EGCS.
For vessels with higher fuel consumption the payback time is naturally much less, and the same happens if the fuel spread increases when demand outweighs supply of MGO in the ECA’s from 2020.
How to Select a Scrubber
Comparing various abatement technologies, there are several options available in the market.
Scrubbers able to comply only with the 0.5%S global cap, single scrubbers, multi-stream scrubbers offered only for Open loop or Closed loop operation.
The challenge is to select the system that really fulfills your needs.
If you wish unrestricted vessel’s operation and full trading flexibility, Clean Marine EGCS is the scrubber you should select for your fleet.
For continuous operation and easy switch between global (0.5%S) and ECA areas (0.1%S) compliance modes, Clean Marine’s Scrubber system is the only system that guarantees time and money saving to the maximum.
Clean Marine’s unique all-stream exhaust gas cleaning system is fully compliant with global (IMO), USCG, regional and local regulations regarding emissions to both air and sea.
Clean Marine EGCS is the best solution to rely on while it ensures global trade without any loss of efficiency and avoiding the costly change-over to MGO.
Clean Marine EGCS system works equally well in open (liquid one time through) and closed (liquid recirculation) modes, while seawater and alkali is used to boost cleaning efficiency and neutralize the acid created in the sulfur trapping process.
The EGCS operates perfect both in port and open sea, at any type of water, including low alkaline and saline water. When choosing the Clean Marine hybrid solution your system operates seamlessly in open/closed loop in all waters and ports without loss of efficiency or time consumption, within the IMO regulations for emissions to air and sea.
If the vessel trades in areas/ports where discharge of wash water is prohibited, the closed loop function will ensure zero discharge to sea as the water is stored in a holding tank. From the holding tank the water is cleaned and may be discharged to sea as soon as the vessel leaves the prohibited area. Given local regulatory variations and uncertainty, the hybrid solution is a safe choice for owners who want full trading flexibility.
Outstanding Open Loop system that enables vessels to transit from high to low alkalinity and salinity water without loss of SOx cleaning efficiency.
In Open Loop the system will ensure the vessel meets the 0,1% sulfur limit also in brackish water, rivers and estuaries. The alkali is automatically dosed and used to regulate the sulfur trapping efficiency when surrounding seawater does not have the sufficient buffering capacity.
The quality of discharged washwater exceeds IMO regulations and meets the much stricter US EPA requirement of a pH of no less than 6 at the ship’s overboard discharge.
The system is specifically developed for seamless and easy operation in all ports and waters; sea, fresh or brackish, with an automatic alkali dosing system which is boosting cleaning efficiency and neutralizing the acid created in the sulfur trapping process.
CM’s EGCS system is a semi-hybrid system in the sense that it incorporates features to boost the cleaning efficiency with alkali like NaOH also in open loop mode.
The features are unique for CM system in the sense that precipitation and scaling risk otherwise associated with mixing sea water with high content of metals with alkaline is taken care of.
Hybrid Features in Open Loop Mode
In addition Clean Marine fullfill requirements of US EPA/VGS pH 6 at discharge point within 3 Nm from US coast without dilution of wash water or running in closed loop mode.

FAQ: Exhaust Gas Cleaning Systems
Why Clean Marine all stream technology is so important?
The fact that Clean Marine EGCS is able to incorporate all exhaust sources into 1 unit makes it possible to avoid different fuel types on board all vessels. 1 fuel world wide.
How Clean Marine EGCS enables vessels to trade in all kinds of water?
Clean Marine EGCS will in open loop utilize NaOh when the alkalinity in the surrounding sea water is to low neutralize the Sulphur in the exhaust.
Why Boilers are so important?
Boilers are an important factor for many vessel types. Both because some vessels has a high fuel consumption for boilers and because it is an advantage to be able to burn the same fuel type for the boilers as for the other machinery.
What are the differences of 0.5 and 0.1 Scrubber?
Clean Marine EGCS do not differentiate between 0,5 and 0,1 scrubbers. Clean Marine EGCS will stop dosing NaOh when reaching 0,5% limit zones.
How Clean Marine EGCS contributes to the maximization of return of investment?
As Clean Marine EGCS is designed to be able to run all exhaust sources in all types of sea water there will be 100% use of high Sulphur HFO in all ship operations. This means that vessels will never need to burn costlier compliant fuel at any time.
Does the system complies with USCG regulations?
As Clean Marine EGCS has a pH of 6 at the vessels discharge point it will comply with VGP that states that dilution of over board discharge water is not allowed to bring pH up to required levels. There is not any need to dilute with so-called reaction water or other means to comply.
