MENU CONTACT TECHNOLOGY Futureproof Hybrid EGCS in one single unit The patented Clean Marine EGCS is specifically designed to meet the needs of the maritime industry and offers proven Allstream exhaust gas handling. All exhaust sources on board can be served by one common EGCS unit, enabling a fast return on investment. In Open Loop the system will ensure the vessel meets the 0,1% Sulphur limit also in brackish water, rivers and estuaries. The alkali is automatically dosed and used to regulate the Sulphur trapping efficiency when surrounding seawater does not have the sufficient buffering capacity. Our EGCS is a seamless hybrid system which enables both open and closed loop modes of operation. The Clean Marine solution is proven to connect all of the ship’s exhaust streams, including the boilers, to one single EGC unit without encountering an increase in back pressure to the combustion units. This is achieved by a unique gas re-circulation mechanism as well as two powerful fans. 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 Sulphur trapping process. Compliant with tomorrow’s regulations The Clean Marine EGCS is an optimal solution for the marine environment and represents a futureproof system for the ship owner, adhering to regulatory variety in all waters. Our system has the ability to combine natural and added alkalinity in open loop operation. This means it will provide high cleaning efficiency while maintaining a pH>6 at the outlet, making the effluent compliant with all IMO and regional/local regulations. 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 our product. Seamless hybrid system When choosing the Clean Marine hybrid-solution the system operates seamlessly in open/closed loop in all waters and ports without loss of efficiency and well within the IMO regulations for emissions to air and sea. If the vessel trades in areas/ports where discharge of washwater 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. Tom Alexander Markussen Tendering Manager +47 98 01 03 64 tam@cleanmarine.no Futureproof and flexible open loop system Clean Marine offers a more flexible Open Loop system than the competitors as it enables vessels to transit from high to low alkalinity and salinity water without loss of SOx cleaning efficiency. The close to neutral pH of the effluent water makes the Clean Marine EGCS a futureproof solution given local regulatory variations and uncertainty. In Open Loop the system will ensure the vessel meets the 0,1% Sulphur limit also in brackish water, rivers and estuaries. The alkali is automatically dosed and used to regulate the Sulphur trapping efficiency when surrounding seawater does not have the sufficient buffering capacity. Great margins The use of alkali as a neutralizing agent enables the Clean Marine EGCS to meet the current pH limit for washwater discharges with good margin. 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 close to neutral pH in effluent water also means it is less corrosive to the hull and piping, thus providing a longer life time of the system and less maintenance cost. Clean Design Clean Marine also offers the only open loop EGCS which complies with the most stringent Environmental Class notation offered by DNV GL: “Clean Design”. In order to qualify for the “Clean Design” notation the pH must be no less than 6 at the overboard discharge, with the exception that during maneuvering and transit, the maximum difference between inlet and outlet of 2.0 pH units is allowed. Major charterers are already requiring “Clean Design” notation for long charters of new-buildings. Given the increasing focus on environmental shipping, we expect this notation to become a competitive advantage for shipowners. The 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-efficent option for vessels with many exhaust sources, as the one EGCS unit simultaneously serve several combustion units.
