From purifiers fuel is sent to service tank. A fuel oil service tank is a tank which contains only the required quality of fuel ready for use. Usually, as per SOLAS requirement, two fuel oil service tanks, for each type of fuel used onboard, are to be provided. Each tank should have a capacity for at least 8 hours operation, at sea, at maximum continuous rating of the propulsion plant and electrical generating plant. #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BxYZPyJA-Q7/?utm_source=ig_tumblr_share&igshid=m826dnfvu6ib

The arrangement and capacity of the treatment plant need to be suitable for ensuring availability of fuel oil for the maximum continuous rating of the propulsion and electrical generating plant. Normally there are two or more treatment equipments which will ensure that failure of one system will not render the other equipment inoperative. #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BxYWifJgz0f/?utm_source=ig_tumblr_share&igshid=21mrzf52oar8

After settling, the fuel is transferred into FO service tank via FO purifiers. These machines are using centrifugal force in order to separate fuel from solid residues and water. This can be achieved by lowering viscosity through heating. In the pictures can be seen another example of high carbon residues content in fuel. #dgtphotos #chiefengineerlog #chief_engineer_log #seafarerslife💯⚓️🚢 #seafarerlife #marineengineer #marineengineering #geodantel #vessels#ships#ocean#water#sea#purifiers#fuel#bunker#bunkering#pumps#mechanicalengineering https://www.instagram.com/p/BxLoyamAdNm/?utm_source=ig_tumblr_share&igshid=26zalw5ri5x9

Main Engine exhaust valve found in satisfactory condition after nearly 36000 hrs of service. As previously explained, ash, vanadium and sodium content should be, preferable, low in order to extend the lifetime of exhaust valves and turbochargers components. #chief_engineer_log #dgtphotos #marineengineer #marineengineering#mainengines#fuels#soot#seafarerlife#seafarer#seaman#seamen#seamenlife#water#ocean#sea#coolmariners#vessels#ships#maintenance#mechanics#mechanicalengineering#enginepower

Few days back we open a unit due piston ring breakage. Unit has around 10000 hrs service. The root cause found to be poor quality fuel with high carbon residue and asphaltenes content. Although HFO purifiers run on low feed rates and temperature close to 98 degC, over time these residues form deposits during combustion and thus favors the fouling of piston rings grooves. The piston rings were very slowly moving in their grooves and the broken one found completely stuck in its groove. #chief _engineer_log#dgtphotos#marineengineer#marineengineering #seafarerlife#seafarer#seaman#seamen#seaman’slife#ayeliens#ocean#sea#water#vessels#ships#mainengines#piston#fuels#sludge#maintenance https://www.instagram.com/p/Bw12DltFfmo/?utm_source=ig_tumblr_share&igshid=1owjaismao6r4

Where a power driven pump is necessary for transferring fuel oil, a stand by pump is to be provided and connected ready for use. The standby pump may be a manual pump or another suitable power driven pump. Usually, DO transfer pump is interconnected with HFO transfer pump and both can serve the same purpose in case needed. #dgtphotos#chief_engineer_log#marineengineer#marineengineering#seafarerlife#seaman’slife#ocean#sea#water#fuel#vessels#ships#bunker#pumps #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwmxnPBBinS/?utm_source=ig_tumblr_share&igshid=1bg1r8p3q1mse

HFO or DO transfer pump is of a volumetric type and is used to transfer the fuel between FO storage tanks and settling tank. #dgtphotos#chief_engineer_log#marineengineer#marineengineering#seafarerlife#coolmariners#sea#ocean#water#fuel#bunker#pumps#seaman’slife #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/Bwmwv7Uh3as/?utm_source=ig_tumblr_share&igshid=136yz9yerdqfl

Sludge pumps are volumetric type pump capable of taking suction from an oil residue tank and delivered to another oil residue tank or shore facility. #dgtphotos#coolmariners#seafarerlife#seamanlife#chief_engineer_log#ocean#sea#water#seaman’slife#seafarers#marineengineer#marineengineering #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/Bwkq3kwBI9R/?utm_source=ig_tumblr_share&igshid=g0nrpyzwkwu2

Oil residue tanks are the tanks which hold sludge directly from which sludge may be disposed through the standard discharge connection or any other approved means of disposal. #chief_engineer_log#dgtphotos#marineengineer#marineengineering#marineengineers#seafarerlife#seamanlife⚓️#seaman’slife#ocean#sea#water#sludgedisposal#fuels#bunkering#vessels#ships#portoperations https://www.instagram.com/p/BwcEuEHl_fr/?utm_source=ig_tumblr_share&igshid=1dfgpc8qzhqc2

Sludge means the residual waste oil products such as those resulted from the purification of fuel or lubricating oils from main or auxiliary machinery or separated waste oil from bilge water separators, oil filtering equipment or oil collected in drip trays and waste hydraulic and lubricating oils. #chief_engineer_log#dgtphotos#marineengineer#marineengineering#seafarerlife#seafarer#seamanlife⚓️#seaman’slife#ocean#sea#fuels#bunkering#sludge#shorefacility#cleanwaters https://www.instagram.com/p/Bwb3jDxguGW/?utm_source=ig_tumblr_share&igshid=h3to8thcuwax

Fuel for the emergency diesel generator is stored in the MGO tank located in the emergency generator room and must always hold sufficient fuel, as per SOLAS requirement, for a minimum 18 hours continuous operation of the engine at full load. #dgtphotos#chief_engineer_log#seafarer#seafarerlife#seamanlife⚓️#marineengineering#marineengineer#seaman’slife#vessels#ships#fuels#bunkering#emergencygenerator#sea#ocean #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwXt-l9hypF/?utm_source=ig_tumblr_share&igshid=18zh248gsa07

Quick closing valves or drop valves are spring loaded type which are used on FO and LO tanks and lines to quickly isolate them in case of an emergency. They are remotely activated, usually from Fire Control Station and they can be pneumatically or hydraulically operates. For smaller tanks, like for Emergency Generator fuel tank, they can be wire connected and operated from outside generator room. After being remotely tripped, the valves must be reset locally, usually by fully closing the valves and then re-opening them. #dgtphotos#chief_engineer_log#seamanlife⚓️#seafarer#marineengineer#marineengineering#vessels#sea#ocean#ships#fuel#bunkering#vesselsystems#seafarerlife #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwXdnldgCYj/?utm_source=ig_tumblr_share&igshid=1qegmy14az88a

Residual bunker is containing, naturally, high values of H2S (hydrogen sulphide). The level of gas increases with heating and agitation during transfer. Atmosphere monitoring of the bunker tanks should be carried out, after bunkering, for up to 72 hours if the presence of H2S is detected using gas monitoring instruments. The maximum permissible value after 24 hrs period following bunkering is 200 ppm. If the content is higher than this, the tank must be vented under controlled conditions. H2S is an enzyme inhibitor of which effect is to temporarily stop the transport of oxygen between body cells. The gas is heavier than the air, highly explosive,invisible and has a smell of rotten egg . The gas will kill the sense of smell in 15 minutes when the concentration is above 100 ppm. Above 500 ppm unconsciousness will quickly set in with respiratory paralysis. It is lethal in a concentration over 1000 ppm. #dgtphotos#chiefengineerlog#marineengineer#seafarer#chemicalelements#marineengineering#seamanlife#sea#ocean#vesses#ships#seafarer#seafarerlife#bunker#fueloils#seamanlife⚓️ #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwWWlJTAOjf/?utm_source=ig_tumblr_share&igshid=1r3hbbtvjp7ws

The tanks are equipped with temperature sensor with alarm (to monitor tank temperature), vent pipe (to eliminate air during bunkering operation and gases when tanks are heated up), level indicator with high level alarm, an overflow line (to release the fuel excedent în case of an overflow), a quick closing valve (to be activated în case of emergency), heating coils to heat up the fuel în order to be transferred and a suction valve. Fuel oil settling and service tanks are equipped with self closing valve for water and settled residues elimination. #dgtphotos#chiefengineerlog#marineengineering#marineengineer#seaman'slife#ocean#sea #vessel#ships #bunker#seaman#seafarer#humansatsea#bunker #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwVHua3hq2C/?utm_source=ig_tumblr_share&igshid=13y436ijb87dr

Bunker tanks are special vessel compartments designed for fuel storage. They can accomodate different fuel grades and can be double bottom tanks or deep tanks. In normal operations the bunker tanks are never filled more than 90 % but some local port regulations require that this is reduced further. They are designed în such a way that a leak from from tank or its connections does not endanger the ship, persons on board or the environment #dgtphotos#chiefengineerlog#seaman'slife#ocean#sea#vessel#ships#bunker#humansatsea#Marineengineering#marineengineer #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwU9xy2hkNr/?utm_source=ig_tumblr_share&igshid=1w96zjblf7ixn

Residual fuels have a high content of heavy aromatic hydrocarbons. These have a high inertia to self ignition and burning. Fuel burning quality can be analyzed through few calculated indicators. CCAI (Calculated Carbon Aromaticity Index) is calculated with the help of cinematic viscosity and density. The higher the value means the higher of aromatic hydrocarbons content which leads to a poor combustion. CII (Calculated Ignition Index) is calculated through same methods as CCAI, but its value is closer to cetanic number and increases with the increment of self ignition sensibility. It’s well known that for a CCAI bigger than 840-860, the combustion is inadequate (Shell recommends a maximum value of 880). Generally, poor combustion quality is specific to low viscosity associated with high density. #dgtphotos#chiefengineerlog#chemicalelements#seafarer#seaman#vessel#ships#marineengineer#marineengineering#ocean#sea#humansatsea#bunkering#fueloil #dgtphotos#chiefengineerlog#marineengineering#sea#ocean#vessel#seaman#engineering#seafarer#marineengines #marineengineer #water #watercraft #bunker#bunkerbarge#coolmariners #marineengineers #marineengineerlife #lifeofamarineengineer #lifeofmarineengineer https://www.instagram.com/p/BwQL8vqFcrT/?utm_source=ig_tumblr_share&igshid=120yboe8a1d78
