Fax signature service annex

so guys welcome back and today we are going to start with nx6 so multiple ns6 is for the regulation for the prevention of air pollution from ships and all marble and axis they have a ratification process and it after that it entered into force on 19th may 2005 its latest so what are the gases which are responsible for air pollution and related to markov nx6 oxides of nitrogen nox sulfur sulfur oxide stocks carbon dioxide co2 carbon monoxide co hydrocarbons their gas suit and some particulates the concentration of different exhaust gases is variable according to engine type engine settings and fuel types so as per that engine rpm and all and type of engine we will see different requirements so as per ammo these are the sega areas or special areas of nx6 for san knox so there are different areas so we have first the seca areas which are sulfur emission control areas baltic sea and north sea english sea and then european waters northwest european waters and then you have californian waters california sources there is a special regulation and circular regarding that and there are different fuel specifications also for that area because of many whales and other aquatic organisms so because these californian waters are very sensitive waters they have decided that within the 20 34 nautical miles of californian baseline they will control the emissions from engines and alternative power sources they will work on and all the greenhouse gases they will apply very stringent limitations now let's see about the application through a markup nx6 applies to all ships and there is a certificate also eia ppp emission control that we will see so certification requirements are depending on the size of vessel but control is applied for all the ships then ships of 400 grt and above international engage in international watches they need to have if from the ratified countries or flying the flag of ratified countries they need to have a iapp certificate international air pollution prevention certificate as well nx6 and this iap certificate will be issued of like all harmonized system of survey by flag state and class on behalf of flagstaff and validity will be five years and annual verification will be there now there is one more certificate required as per nx6 eia ppp eiapp that is indian international air pollution prevention certificate that is required for different types of engine as described later on that regarding to the nox emission so nox emission is dependent on your indian rpm and design and sox emission is dependent on your fuel emissions so for fuel emissions and all we have iapp certificate and for nox we have eiapp certificate and nx6 require that every ship of four energy rt and above and even for use for fixed and floating drilling objects they are subject to the initial and other harmonized system of service periodical surveys and five yearly in renewal surveys then minimum of one intermediate survey during the period of validity so same rv system of surveys applicable and in the case of shifts of less than 400 grt the administration has different requirements so these are your main regulations in nx6 of marpol which we have which are concerning to us first is regulation 12 that is emissions from ozone depleting substances like you have from refrigerant plants ac and some firefighting equipment then regulation 13 is talking about your knocks and emissions so nox emissions from diesel engines that we will see then regulation 14 is talking about sulfur oxides emissions from ships sox emissions regulation 15 is volatile organic compounds emission from cargo tanks of all tankers that is talking about vapor emission control system that we were saying is also required by nx6 regulation 15. then regulation 16 is emissions from shipboard incinerators which are causing some emissions from incinerations then regulation 18 is fuel oil capacity your bunker oil samples and all that mark4 and x6 and there is a technical code for macbool and x6 which has some requirements as per the following about your ozone depleting substances from refrigerant plants and fire fighting equipment so the first requirement is that any all ozone depleting substances are prohibited on ship from 2005 and if you find some substance which is emitting any ozone depleting substances then you have to remove them to reception facilities as fast as soon as possible then from first january 2020 no installation is permitted on chip which contains hcfc hydrofluorochlorocarbons which are oxygen depleting substances for example refrigerants in ac different on 22 these are ozone depleting substances and they are banned then on board ship we have to maintain a record book which contains a list of ozone depleting substances and like use of freon and other these things are banned and its list has to be maintained if there are any like helon is not approved or prohibited to use in fire extinguishing system so these rules and regulations should always be complied so next is regulation 13 about nox emissions from diesel engines so first we will see that to which ships these nox emissions apply so it applies to diesel engines first is if your engine has more than 130 kilowatt hours power then and it is constructed after first january 2000 then or if it is more than 130 kilowatt power and it is gone under major conversion after first january 2000 either it is installed after january 2000 or it undergoes any major conversion after january 2000 then you need to comply with no extermination regulations and also if your engine is more than 5000 kilowatt power and displacement uh per cylinder or at or above 90 liters which is installed on a ship after january uh 1990 or and prior to january 2000 so these are the application requirements then which ships it does not apply to so it does not apply to engines which are used for emergency like lifeboat engine or your emergency generator and also which are solely used for like exploration or seismic surveys or explore exploitation or offshore platforms sea of seabed minerals resources and all these places this knox technical code is not applicable because in they are used for emergency only then let's see the requirements for your nox emissions so it is a three-tier approach which is dependent on different constructions of ship in different years so if your ship is constructed between 2000 to january 2011 and depending on the rpm of your ship if your ship's rpm is less than 130 then you can emit 17 gram per kilowatt of your nox depending on the kilowatt size of the ship of the engine and if your rpm is between 130 and 2000 then 45 into and to the power minus 0.2 this much grams per kilowatt hour of nox you can emit and if it is more than 2000 rpm then you can emit 9.8 grams per kilowatt hour of your engine then next is tier 2 if your ship is constructed between january 11 or after january 11 then uh your emissions if again depending on the rpm if the rpm is less than 130 then you can you have to reduce your nox emissions to 14.4 grams per kilowatt hour and if it is between 130 to 2000 then 44 into n to the power minus 0.23 so you can see it's slowly slowly reducing then 7.7 grams per kilowatt hour if your rpm is more than 2000 now tier 3 is if your ship is constructed after first january 2006 then you have additional limitations especially in your emission control areas so if your ship is operating in nox emission control areas the allowable emissions are if the rpm is less than 130 you can see it's going from 14.4 to 3.4 grams per kilowatt hour so this is the most reduction uh vast drastic reduction and for this many ships were not equipped so they had to install some scrubbers or this exhaust gas cleaning system recirculation system so many things to get nox emission in control so three um for ships constructed after january 2016 and rpms less than 130 3.4 grams per kilowatt hour because most of the ships are merchandise rpm is less than 130 then if it is between 130 to 2000 9.0 into n to the power minus 0.2 grams per kilowatt hour and if it is more than 2002 grams per kilowatt so here also you can see from [Music] 44 it's directly coming to nine so quite a drastic change is there then then we need to also know what are the factors which are affecting the amount of nitrogen oxides which are coming out of your engine so your fuel injection timing will uh control the amount of nitrogen oxides nox coming out of the system injection system components your nozzle or injectors the fuel pumps and your software which is controlling your engine and fuel injections or the hardwares that is your fuel injection control then your camshaft components inlet and exhaust cam then wall timings how much timing the exhaust falls are closing and opening combustion chambers inside your cylinders piston cylinder head and cylinder liners how are they what is the compression ratio how much the connecting rod piston rod and shim gaskets they are getting moving and timings and all and how much is the friction then turbocharger what type it is and build what type of air cooler is there or three heaters there your auxiliary blower design then what are the water injection knox reducing equipment you are using then emulsified fuel what is your fuel water emulsion ratio nox reducing equipment for exhaust gas recirculation are you using exhaust gas recirculation or not because obviously exhaust gas recirculation will reduce your nox equipment nox emissions and there is a two types of either you have exhaust gas recirculation or you have selective catalytic reduction where some elements are added in the exhaust system that we will see and you need to have a nox technical file which has to be maintained on the ship for any engine so actual technical file of any engine may include less components and or parameters other than the list above depending on the particular engine and the specific so you should need to have a specific knox technical file so we already saw what are the various things which are affecting our knox emission and same things mostly we have to control to control our nox emissions so for all old ships we have us we can introduce new injectors fuel injectors which are controlling nox emissions then retarding the injection timing of the fuel then temperature control of your charging air exhaust gas recirculation as we saw or our selective catalytic reduction then fuel water emerging or water injection system we can use then humid air motor technique where we are adding some wet steam to the engine these are for mostly existing engines then for new engines of course they have to be pre-certified that they will emit so much of less knocks as for the regulations we need to have a technox technical file for clarification of the engines and their groups and the final certification and as for regulation 13 uh requirements are fully defined by nox technical codes there is a special nox technical port which is an attachment to the markboard because there are a lot of special clarifications and requirements for the engines to reduce nox emissions and there are recommended readings for each type and rpm of design of the engines multiply different groups and the certification of engine as per the manufacturer should be checked before installing them and all the settings and the ship should have of course eiapp and iapp then psc also have to do inspections like your verification and compliance and all these measures they have to check as per the nox technical file and nox technical code then we have regulation 14 which is talking about your stocks emissions from ships same it came with this nx6 2005 and there it's related to two things either shocks and the particulate matter which is emitting from your ship's engines and it will be controlled by the sulphur content in the fuel so these are the limits of your fuel which can emit how much what amount of sulphur oxides in different areas there are special areas of nx6 cell prevention control areas so if you are outside surfer emission control areas before january 2012 we could emit 4.5 percent mass by mass of sulphur and from january 2012 to 2020 till now we could emit 3.5 percent this is also a three tier method so every five ten years we are changing and then after january 2020 from this year point five percent mass by mass we can use uh amid sulfur outside sega areas now inside sega areas previously it was 1.5 till 2010 and then from 2010 to 2015 it's one percent and now it's only 0.1 percent mass by mass sulphur you can emit from engine exhaust or type of fuel you have you are using or either you are putting scrubbers nowadays so scrubbers are being installed tanks uh fuel oil tanks are being getting cleaned to change over from vlsfo from low sulphur and diesel oil to vlsfo and uls very very low sulphur oils and ultra large low sulfur oils then these are the seca area sulphur emission control areas the baltic sea north sea north american area northwest europe in your waters and united states caribbean sea and slowly slowly all the nox emission control areas also will be same as your second areas so this is the diagram you can see this is your north sea baltic sea then your northwest european waters mediterranean now since we saw that we have different requirements for sakai areas fuel oil and outside seca areas fuel oil so if you are in special area if you are operating outside special area you will have suppose in 20 20 point five percent by m by m fuel oil so when you are going into second area like north sea you have to change over from point five percent sulfur fuel oil to ultra large that is point one percent fuel oil content of sulphur so then you need to change over the fuel oil and as per your ship design and equipment it will take long time so before you enter into the echo area you have need the changeover should complete and you need to have locked down all the details when and how you started your changeover and enter your entry into a area and your change over completion time similarly when you are coming out of eka area again the changeover can start only when you are outside eka area and all the records have to be maintained in the logbook or if as per flag state requirement or oil record book so what are the different arrangements are provided for shocks control so we are doing following things for controlling the sulphur emissions we have different fuel oils and different tanks with different fuel oils different ports having different oils and changing over might take from 12 to 24 hours and depending on the type of ship then for cylinder oil also we have two qualities of oils then we have need to have a thorough sampling whenever we are doing changeover need to can keep the samples and get in check proper documentation and logging down all the procedures so these are the different designs for handling different fuels with different service and settling tanks then there are some other methods of controlling nox and socks like we have exhaust gas cleaning system or other systems then we have plants reliquation plant for lng and lpg carriers where we are controlling noxian socks by using lng in the fuel alpha lubricator system electronic control engines turbo charger turbo generator plant where high efficiency of air flows for power takeoff and reduces the fuel and emission reduction is there in system integration as we saw human air motor where steam is passed in the red steam is passed in the engine engine intake air operating with water and exhaust gas recirculation 50 reduction of emission then hfo sulfur content of the fuel oil low sulphur fuel oils are used and dual fuel options are there in the ships for saka areas then also as you know many ships are installing scrubbers because some ships are not some engines are not ready to use this very low sulphur fuel oil it's very thin and many pipelines are leaking or the engine is not equipped to use this type of fuel so they are installing scrubber so that the regulations of sulphur cap are complied so this exhaust gas is passed through the scrubber and the as per the requirement is reduced and last is about your volatile organic compound emissions from cargo oil tanks which is a separate chapter in video which we will see separately then today's this videos last main point is that last points will cover separate thing separate video so regulation 18 is about fuel oil quality which is controlled by you should have a bunker delivery note from the supplier then you should have samples and you have to retain the bunker delivery note and the samples for three years and there are special requirements for bunker samples the size of bottle and everything how the inspection saturn you have to obtain um msds every time from the supplier the latest specifications of the fuel sulfur content and with all the ship's details of name and all date of delivery fuel sulphur content product name intensity and all and declaration that the fuel supply meets the regulation as per marphone then these are the fuel sampling requirements that are same sampling is required as per the guidelines and pdn has to be there then you need to put a proper label where was the sample taken bunkering done size of sample is 400 ml and sample has to be retained for at least one years and port state and all have to do the inspections so guys don't forget to like subscribe and we'll keep continuing with this more uh videos regarding knox technical final other details of nx6 thank you
