Ballast water Management Systems [Page 2] Scrubbers & Selective Catalytic Reduction System(SCR) [Page 7] Dual Fuel Engines with LNG [Page 11] 01 BALLAST WATER MANAGEMENT SYSTEM Ballast Water Treatment - A Background Ballast water is taken from one ecological zone and discharged into another by the trading vessels across the globe potentially causing invasion on local aquatic organism, natural resources and harming the biodiversity. Maritime community has acknowledged the gravity of the detrimental impacts that this may have on the local biodiversity, economy or even the human health of communities in the surrounding areas. Impending IMO regulations require BWT plants to be installed on most of the existing vessels around the world. Cybermarine's systematic retrofit approach ensures the selection of the most suitable technology that can be integrated into the existing systems and structures and installed in a cost effective way. The different technologies for treating the ballast water are: ► Solid Liquid Separation o Mechanical Filtration o Hydrocyclone o Chemical enchantment (Coagulation / Flocculation) ► Chemical Disinfection o Chlorination o Electro-chlorination o Ozonation ► Physical Disinfection o Ultraviolet Irradiation (UV) o De-oxygenation o Cavitation For most efficient solution the system shall comprises of two stages of treatment with solid liquid separation method being followed by either of disinfection methods. There are several technical, operational, geological and cost considerations to be taken into account while choosing the right BWM solution. 02 BALLAST WATER MANAGEMENT SYSTEM 6 1: STRAINER 2: BALLAST PUMP 3: FILTER 4: CHLORINATING UNIT 5: NEUTRALIZATION UNIT 6: CONTROL MONITORING SYSTEM 7: TOTAL RESIDUAL OXIDANT ANALYSER Ballast Water Management System using Chlorinating Unit 1: STRAINER 2: BALLAST PUMP 3: FILTER 4: ULTRAVIOLET IRRADIATION Ballast Water Management System using Ultraviolet Irradiation 1: STRAINER 2: BALLAST PUMP 3: HYDROCYCLONE 4: WATER TREATMENT TANK 5: EDUCTOR 6: AIR COMPRESSOR 7: AIR DRYER 8: AIR RECEIVER TANK 9: OZONE GENERATOR Ballast Water Management System using Ozone Generator 03 BALLAST WATER MANAGEMENT SYSTEM What Cybermarine Offers: We offer a complete gamut of Design and Engineering solution right from Conception till Installation.

The IMO ship pollution rules set limits for sulfur oxide and nitrogen oxide emissions from ship exhausts. Every ship is unique and requires a comprehensive evaluation when selecting and planning for the optimal solution for the reduction of SOx with Scrubbers and NOx with Selective Catalytic Reduction (SCR) plants. The new regulations mean that the limit value for sulphur in the Baltic Sea, the North Sea and the English Channel (so-called sulphur control areas or Sulphur Emission Control Areas [SECA]) has been lowered to 0.1% of weight in 2015 and globally to 0.5% of weight in 2020 or, depending on fuel supply, at the latest by 2025. To comply with the regulation, shipping operators should use lower sulphur fuels or install technical 'abatement' equipment, such as scrubbers, which achieve equivalent results. An argument in favour of Liquefied Natural Gas (LNG) as fuel, compared to Heavy Fuel Oil (HFO) is that it will reduce Carbon Dioxide (CO2) emissions by up to 30% and bring nitrogen oxide (NOx) emissions to 20% of current levels, which will satisfy the upcoming Tier III emission requirements without further actions. Maximum Sulphur content of marine bunker fuel based on Annex VI of MARPOL. Note:SECA stands for Sulphur Emission control area. NOx Emmission limit schedule according to IMO 07 SCRUBBER AND SCR SYSTEM Technologies Available SCRUBBER SYSTEM By installing exhaust gas scrubbers, vessels will be able to bring down sulphur content in exhaust emissions thereby enabling use of fuel currently in usage for marine vessels. Different types of Scrubber systems are: ► Open Loop Systems Seawater alkalinity is used to neutralize the Sulphur in the exhaust and the benefit of the seawater scrubber is its simplicity; no fresh water or additional chemicals are needed for operation. 1: SEA WATER COOLING PUMP 2: SCRUBBER 3: WATER TREATMENT UNIT 4: SLUDGE TANK ► Closed Loop Systems When the salinity of the water is too low to allow for effective cleaning capability of the open loop system, closed loop system using fresh water with the addition of a caustic soda (NaOH) solution is used to neutralize the Sulphur. 1: SEA WATER COOLING PUMP 2: HEAT EXCHANGER 3: SCRUBBER 4: NaOH UNIT 5: CIRCULATING PUMP 6: PROCESS TANK 7: WATER TREATMENT UNIT 8: SLUDGE TANK 9: HOLDING TANK 08 SCRUBBER AND SCR SYSTEM ► Hybrid Systems The third alternative for wet scrubbers is a hybrid with an open loop seawater system and a closed loop freshwater system with the addition of chemicals. 1: SEA WATER COOLING PUMP 2: HEAT EXCHANGER 3: SCRUBBER 4: NaOH UNIT 5: CIRCULATING PUMP 6: PROCESS TANK 7: WATER TREATMENT UNIT 8: SLUDGE TANK 9: HOLDING TANK 1.

HOLDING TANK Closed Loop Scrubber System 09 SCRUBBER AND SCR SYSTEM SELECTIVE CATALYTIC REDUCTION SYSTEM (SCR) The main technique used is Selective Catalytic Reduction (SCR), which converts harmful nitrogen oxides into harmless nitrogen and water with the aid of a catalyst (ammonia or urea). A NOx reduction level of above 90% can be achieved. The systems are still quite bulky and there is room for development. Due to temperature requirements, the catalytic reactor occupies space in the engine casing close to the engine and in addition a urea tank and a feed system are required. Other techniques such as fuel/water emulsions and Humid Air Motor (HAM) also exist, but are not that common in the marine industry. 1: AIR COMPRESSOR 2: NOx REACTOR 3: DOSING UNIT 4: UREA TANK 5: UREA SUPPLY PUMP What Cybermarine Offers: Integration Design and Engineering We will help you in identifying and developing the right method of integrating the system in the existing vessel with minimum compromise on layout ergonomics. We will then engineer the entire solution by developing the retrofit design and layouts, detail engineering drawings, including structural modification plans and generating the bill of material as per relevant Class Standards. We will also provide technical support during the installation at the Shipyard. 10 DUAL FUEL ENGINES WITH LNG Background - LNG Retrofits We are here to help you to retrofit your existing Diesel/HFO fuel propulsion engines and/or Generator sets with LNG powered engines or Dual Fuel Engines. This will not only cut the pollution levels in exhaust gas emissions, but will also reduce your fuel spendings. Various studies show a significant reduction in the NOX, SOX, GHG on converting from contemporary HFO engines to dual fuel engines. The table below from IACS publication illustrates the point: NOx emission SOx emission Green House Gases 80-90 % reduction Zero emission 20-25% reduction The overall retrofits include: 1. Dual Fuel Engine The dual fuel engines of suitable capacity can be selected from a host of makes such B&W, Watrsalia, Rolls Royce to power the vessel by replacing the existing engines. 2. LNG Storage Tanks These are IMO Type-C cryogenic tanks of suitable volume to cater to the needs of the voyage requirements and to the availability bunkering facility. 3. LNG Vaporizer and Heater These units are installed with the LNG Tanks so as to vaporise and condition the LNG fuel to meet the temeperature/pressure delivery requirements of the engine. Moreover it is also helpful in maintaining the pressure in the tanks. 4. Gas Valve Unit (GVU) This system includes an array of manifolds and valves intended distribute the conditioned LNG fuel to the individual engines. 5. Gas Combustion Unit (GCU) This is an optional system provided to enable the vessel to take care of the boil off gas produced in the tank in the due course of it's storage. 11 DUAL FUEL ENGINES WITH LNG The schematic representation of the aforesaid system is shown in the figure: 1: LNG TYPE-’C’ FUEL TANK 2: LNG VEPORIZER 3: GAS HEATER & COOLER 4: GAS VALVE UNIT (GVU) 5: DUAL FUEL ENGINE 6: DUAL FUEL BOILER / GAS COMBUSTION UNIT (GCU) 7: LNG MANIFOLD 8: HEAVY FUEL OIL DAY TANK The given modification reduces the SOx, NOx emission to such an extent that it negates the requirement for the installation of separate scrubber, SCR, EGR systems.
