Bir geminin HFO yak\u0131t al\u0131m\u0131nda en pahal\u0131 hata, yaln\u0131zca ton fiyat\u0131na bakarak verilen karard\u0131r. Yanl\u0131\u015f viskozite, uyumsuz iki parti yak\u0131t\u0131n ayn\u0131 tanka bas\u0131lmas\u0131 veya eksik teslimat dok\u00fcmantasyonu; sefer program\u0131n\u0131, makine g\u00fcvenilirli\u011fini ve MARPOL uyumunu ayn\u0131 anda riske sokabilir. HFO yak\u0131t tedariki bu nedenle bir emtia sat\u0131n al\u0131m\u0131 de\u011fil, yak\u0131t spesifikasyonu, tank y\u00f6netimi, teslimat lojisti\u011fi ve kan\u0131tlanabilir kalite kontrol\u00fcnden olu\u015fan operasyonel bir s\u00fcre\u00e7tir.<\/p>\n

HFO yak\u0131t nedir ve hangi operasyonlara uygundur?<\/h2>\n

HFO, Heavy Fuel Oil tan\u0131m\u0131n\u0131n k\u0131saltmas\u0131d\u0131r ve genellikle rafinasyonun rezid\u00fcel bile\u015fenlerinden olu\u015fan a\u011f\u0131r deniz yak\u0131tlar\u0131n\u0131 ifade eder. Y\u00fcksek enerji yo\u011funlu\u011fu ve uygun birim maliyeti, onu \u00f6zellikle uygun makine altyap\u0131s\u0131na sahip ticari gemilerde \u00f6nemli bir se\u00e7enek h\u00e2line getirir. Ancak HFO’nun kullan\u0131m de\u011feri, yak\u0131t\u0131n fiyat\u0131ndan \u00e7ok geminin yak\u0131t sistemi, separat\u00f6r kapasitesi, \u0131s\u0131tma d\u00fczeni ve emisyon kontrol ekipman\u0131yla belirlenir.<\/p>\n

HFO, MGO veya LSMGO gibi distilat yak\u0131tlardan daha y\u00fcksek viskoziteye sahiptir. Bu nedenle depolama, transfer ve enjeksiyon \u00f6ncesinde kontroll\u00fc \u0131s\u0131tma gerektirir. Yak\u0131t\u0131n bunker manifoldundan al\u0131nmas\u0131 ile ana makineye ula\u015fmas\u0131 aras\u0131ndaki her a\u015fama – settling tank, service tank, separat\u00f6r ve \u0131s\u0131t\u0131c\u0131lar – hedef viskoziteyi koruyacak \u015fekilde de\u011ferlendirilmelidir. \u00d6zellikle uzun s\u00fcre d\u00fc\u015f\u00fck y\u00fckte \u00e7al\u0131\u015fan veya s\u0131k liman manevras\u0131 yapan gemilerde bu gereksinimler daha kritik h\u00e2le gelir.<\/p>\n

HFO ile VLSFO ayn\u0131 kavram de\u011fildir. VLSFO, k\u00fck\u00fcrt i\u00e7eri\u011fi bak\u0131m\u0131ndan k\u00fcresel MARPOL s\u0131n\u0131r\u0131na g\u00f6re form\u00fcle edilmi\u015f \u00e7ok d\u00fc\u015f\u00fck k\u00fck\u00fcrtl\u00fc yak\u0131t s\u0131n\u0131f\u0131n\u0131 ifade eder. HFO ise daha geni\u015f bir rezid\u00fcel yak\u0131t tan\u0131m\u0131d\u0131r. Bir talepte yaln\u0131zca HFO yazmak, \u00e7o\u011fu zaman yeterli teknik y\u00f6nlendirme sa\u011flamaz. Talepte hedef viskozite, maksimum k\u00fck\u00fcrt, ISO 8217 kalite s\u0131n\u0131f\u0131, beklenen t\u00fcketim ve teslim al\u0131nacak liman a\u00e7\u0131k\u00e7a belirtilmelidir.<\/p>\n

K\u00fck\u00fcrt s\u0131n\u0131r\u0131 karar\u0131n merkezindedir<\/h3>\n

MARPOL Ek VI kapsam\u0131nda uygulanacak k\u00fck\u00fcrt limiti, yak\u0131t se\u00e7iminin ilk kontrol noktas\u0131d\u0131r. Akdeniz Emisyon Kontrol Alan\u0131’nda 1 May\u0131s 2025 itibar\u0131yla ge\u00e7erli y\u00fczde 0,10 k\u00fck\u00fcrt limiti, Ege ve Akdeniz seferi yapan gemiler i\u00e7in planlamay\u0131 do\u011frudan etkiler. Gemide e\u015fde\u011fer emisyon azalt\u0131m y\u00f6ntemi olarak scrubber bulunmuyorsa, kullan\u0131lacak yak\u0131t\u0131n bu s\u0131n\u0131r\u0131 sa\u011flamas\u0131 gerekir.<\/p>\n

Scrubber bulunan bir gemide daha y\u00fcksek k\u00fck\u00fcrtl\u00fc rezid\u00fcel yak\u0131t kullan\u0131m\u0131 teknik olarak de\u011ferlendirilebilir; fakat bu karar otomatik bir maliyet avantaj\u0131 anlam\u0131na gelmez. A\u00e7\u0131k \u00e7evrim, kapal\u0131 \u00e7evrim veya hibrit sistemin liman ve b\u00f6lgesel de\u015farj kurallar\u0131yla uyumu; y\u0131kama suyu kapasitesi, bak\u0131m durumu ve operasyon b\u00f6lgesi birlikte incelenmelidir. Yak\u0131t se\u00e7imi, sadece tanktaki \u00fcr\u00fcn\u00fcn fiyat\u0131na de\u011fil, geminin toplam uyum maliyetine g\u00f6re yap\u0131lmal\u0131d\u0131r.<\/p>\n

Tedarikten \u00f6nce teknik kontrol listesi de\u011fil, teknik karar gerekir<\/h2>\n

HFO al\u0131m\u0131ndan \u00f6nce kaptan, ba\u015fm\u00fchendis, gemi i\u015fletmecisi veya acente aras\u0131ndaki bilgi ak\u0131\u015f\u0131 net olmal\u0131d\u0131r. Yak\u0131t\u0131n hangi tanka al\u0131naca\u011f\u0131, tankta kalan \u00fcr\u00fcn\u00fcn miktar\u0131 ve \u00f6zelli\u011fi, son al\u0131nan partinin laboratuvar sonucu ile sonraki limana ETA bilgisi ayn\u0131 de\u011ferlendirme i\u00e7inde yer almal\u0131d\u0131r. Bu veriler olmadan verilen bir RFQ, tedarik\u00e7iden do\u011fru teklif al\u0131nsa bile teslimat s\u0131ras\u0131nda sorun yaratabilir.<\/p>\n

\u00d6ncelikle yak\u0131t\u0131n gemi \u00fcreticisi ve makine i\u015fletme limitleriyle uyumlu viskozitede olup olmad\u0131\u011f\u0131 kontrol edilmelidir. Ard\u0131ndan yo\u011funluk, parlama noktas\u0131, su i\u00e7eri\u011fi, toplam sediment, al\u00fcminyum ve silikon bile\u015fenleri gibi parametreler ele al\u0131nmal\u0131d\u0131r. Katalitik ince par\u00e7ac\u0131klar olarak bilinen al\u00fcminyum ve silikon, etkin separat\u00f6r ayar\u0131 yap\u0131lmad\u0131\u011f\u0131nda yak\u0131t pompalar\u0131, enjekt\u00f6rler ve silindir g\u00f6mlekleri \u00fczerinde a\u015f\u0131nma riskini art\u0131rabilir.<\/p>\n

Yak\u0131t\u0131n stabilitesi ve mevcut stokla uyumlulu\u011fu da ayn\u0131 derecede \u00f6nemlidir. \u0130ki ISO 8217 uyumlu parti, birbirleriyle kar\u0131\u015ft\u0131r\u0131ld\u0131\u011f\u0131nda her zaman sorunsuz davranmayabilir. Uyumsuzluk; \u00e7\u00f6kelti olu\u015fumu, filtre y\u00fck\u00fcn\u00fcn artmas\u0131 ve separat\u00f6r performans\u0131n\u0131n d\u00fc\u015fmesiyle kendini g\u00f6sterebilir. Tankta kalan \u00fcr\u00fcn\u00fcn niteli\u011fi belirsizse, m\u00fcmk\u00fcn oldu\u011fu \u00f6l\u00e7\u00fcde segregasyon yap\u0131lmal\u0131 ve numune \u00fczerinden uyumluluk de\u011ferlendirmesi istenmelidir.<\/p>\n

Teslimat y\u00f6ntemi yak\u0131t\u0131n kendisi kadar \u00f6nemlidir<\/h3>\n

Barge-to-ship teslimat\u0131, \u00f6zellikle b\u00fcy\u00fck miktarl\u0131 HFO ikmallerinde yayg\u0131n ve verimli bir y\u00f6ntemdir. Ancak bar\u00e7 operasyonu i\u00e7in minimum miktar<\/a>, r\u0131ht\u0131m veya demir sahas\u0131 uygunlu\u011fu, hava ko\u015fullar\u0131, g\u00fcvenli yana\u015fma ve vardiya plan\u0131 teyit edilmelidir. T\u00fcrkiye’deki bir\u00e7ok operasyon i\u00e7in 100 MT ve \u00fczeri talepler bar\u00e7 planlamas\u0131na daha uygun olabilir; kesin uygunluk liman, terminal ve teslimat penceresine ba\u011fl\u0131d\u0131r.<\/p>\n

Marina r\u0131ht\u0131mlar\u0131nda road tanker teslimat\u0131, daha d\u00fc\u015f\u00fck hacimli operasyonlar i\u00e7in pratik olabilir. Bununla birlikte HFO’nun \u0131s\u0131tma ve transfer gereksinimleri nedeniyle tanker ekipman\u0131, hortum g\u00fczerg\u00e2h\u0131, manifold eri\u015fimi ve geminin kabul d\u00fczeni \u00f6nceden kontrol edilmelidir. Road tanker teslimatlar\u0131nda 2.000 litre ve \u00fczeri minimum miktarlar s\u0131k g\u00f6r\u00fcl\u00fcr. Shore-to-ship pipeline ise ba\u011flant\u0131n\u0131n mevcut oldu\u011fu tesislerde h\u0131z ve kontrol avantaj\u0131 sa\u011flar; fakat r\u0131ht\u0131m tahsisi ile terminal prosed\u00fcrleri teslimat takvimini belirler.<\/p>\n

Teslimat y\u00f6ntemi se\u00e7ilirken ETA koordinasyonu kritik bir maliyet kalemidir. Geminin erken veya ge\u00e7 gelmesi, bar\u00e7\u0131n beklemesine, r\u0131ht\u0131m plan\u0131n\u0131n de\u011fi\u015fmesine ya da tedarikin sonraki operasyon penceresine kaymas\u0131na neden olabilir. Talep a\u015famas\u0131nda ETA, ETD, berth bilgisi, manifold \u00e7ap\u0131, talep edilen miktar, yak\u0131t derecesi ve ileti\u015fim sorumlusu birlikte payla\u015f\u0131lmal\u0131d\u0131r.<\/p>\n

ISO 8217 ve MARPOL belgeleri teslimat\u0131n ayr\u0131lmaz par\u00e7as\u0131d\u0131r<\/h2>\n

ISO 8217, deniz yak\u0131tlar\u0131n\u0131n \u00f6zelliklerini s\u0131n\u0131fland\u0131rmak ve kalite beklentisini tan\u0131mlamak i\u00e7in kullan\u0131lan temel standartt\u0131r. Standart, yak\u0131t\u0131n her operasyon ko\u015fulunda kusursuz olaca\u011f\u0131n\u0131 garanti etmez; ancak sipari\u015f spesifikasyonu, analiz de\u011ferlendirmesi ve olas\u0131 uyu\u015fmazl\u0131k y\u00f6netimi i\u00e7in ortak teknik dil sa\u011flar. Bu nedenle teklif \u00fczerindeki \u00fcr\u00fcn ad\u0131 yerine, teklifin hangi ISO 8217<\/a> s\u0131n\u0131f\u0131na dayand\u0131\u011f\u0131 sorgulanmal\u0131d\u0131r.<\/p>\n

Teslimat s\u0131ras\u0131nda temsil\u00ee numune alma prosed\u00fcr\u00fc<\/a> dikkatle uygulanmal\u0131d\u0131r. S\u00fcrekli damlatmal\u0131 numune alma d\u00fczeni, teslimat boyunca yak\u0131t ak\u0131\u015f\u0131n\u0131 temsil eden numuneye ula\u015fmak i\u00e7in tercih edilen y\u00f6ntemdir. Numunelerin uygun \u015fekilde m\u00fch\u00fcrlenmesi, etiketlenmesi ve taraflarca kay\u0131t alt\u0131na al\u0131nmas\u0131; sonradan ortaya \u00e7\u0131kabilecek kalite iddialar\u0131nda temel delil niteli\u011findedir.<\/p>\n

Bunker Delivery Receipt veya BDR, MARPOL kapsam\u0131nda teslimat\u0131n k\u00fck\u00fcrt bilgisi ve di\u011fer zorunlu ayr\u0131nt\u0131lar\u0131 a\u00e7\u0131s\u0131ndan kritik belgesidir. BDR \u00fczerindeki gemi ad\u0131, IMO numaras\u0131, teslimat yeri, tarih, miktar, yo\u011funluk, k\u00fck\u00fcrt beyan\u0131 ve tedarik\u00e7i bilgileri teslim tamamlanmadan \u00f6nce kontrol edilmelidir. Miktar fark\u0131, s\u0131cakl\u0131k kaynakl\u0131 hacim de\u011fi\u015fimi veya belge ile sipari\u015f aras\u0131ndaki spesifikasyon fark\u0131 varsa, bu durum teslimat notlar\u0131na a\u00e7\u0131k bi\u00e7imde i\u015flenmelidir.<\/p>\n

Platts-indexli fiyat\u0131 do\u011fru okumak<\/h2>\n

\u015eeffaf bir HFO teklifi, referans fiyat\u0131 ve bu referansa uygulanan fark\u0131 ayr\u0131 de\u011ferlendirmeyi m\u00fcmk\u00fcn k\u0131lar. Platts-indexli fiyatland\u0131rmada toplam bedel genellikle ilgili \u00fcr\u00fcn endeksi, fiyat ge\u00e7erlilik penceresi ve operasyonel farklardan olu\u015fur. Liman, hacim, bar\u00e7 veya tanker mobilizasyonu, teslimat zaman\u0131, \u00f6deme ko\u015fulu ve tedarik zinciri maliyetleri bu fark\u0131 etkileyebilir.<\/p>\n

Bu nedenle iki teklif aras\u0131ndaki fiyat fark\u0131n\u0131 de\u011ferlendirirken ayn\u0131 endeksin, ayn\u0131 fiyat g\u00fcn\u00fcn\u00fcn, ayn\u0131 k\u00fck\u00fcrt spesifikasyonunun ve ayn\u0131 teslimat kapsam\u0131n\u0131n kullan\u0131ld\u0131\u011f\u0131ndan emin olunmal\u0131d\u0131r. Daha d\u00fc\u015f\u00fck g\u00f6r\u00fcnen teklif; bekleme, mobilizasyon, analiz, teslimat saatleri veya ilave hizmetler bak\u0131m\u0131ndan farkl\u0131 bir kapsam ta\u015f\u0131yabilir. Kar\u015f\u0131la\u015ft\u0131r\u0131labilir fiyat, e\u015fde\u011fer \u00fcr\u00fcn ve e\u015fde\u011fer teslimat ko\u015fullar\u0131 \u00fczerinden yap\u0131lan fiyatt\u0131r.<\/p>\n

Dijital RFQ s\u00fcreci burada operasyonel avantaj sa\u011flar. Birden fazla gemiyi y\u00f6neten ekipler, her geminin yak\u0131t ge\u00e7mi\u015fini, tank kapasitesini, tercih edilen \u00fcr\u00fcn s\u0131n\u0131f\u0131n\u0131 ve yakla\u015fan liman \u00e7a\u011fr\u0131lar\u0131n\u0131 d\u00fczenli kay\u0131t alt\u0131nda tutabilir. Marinefill gibi dijital i\u015f ak\u0131\u015flar\u0131, teklif, tedarik\u00e7i ileti\u015fimi, teslimat teyidi ve dok\u00fcmantasyonu ayn\u0131 operasyon kayd\u0131nda birle\u015ftirerek telefon ve mesaj trafi\u011finden do\u011fan bilgi kayb\u0131n\u0131 azalt\u0131r.<\/p>\n

Kabul sonras\u0131 ilk saatler belirleyicidir<\/h2>\n

Yak\u0131t manifolddan ge\u00e7ip BDR imzaland\u0131\u011f\u0131nda operasyon bitmi\u015f say\u0131lmaz. Al\u0131nan miktar tank sounding verileriyle kar\u015f\u0131la\u015ft\u0131r\u0131lmal\u0131, numuneler g\u00fcvenli \u015fekilde saklanmal\u0131 ve yak\u0131t\u0131n settling tank ile separat\u00f6r ge\u00e7i\u015f plan\u0131 haz\u0131rlanmal\u0131d\u0131r. \u00d6zellikle yeni bir tedarik partisinde, filtre diferansiyel bas\u0131n\u00e7lar\u0131, separat\u00f6r \u00e7\u0131k\u0131\u015f\u0131 ve ana makine performans\u0131 ilk kullan\u0131m d\u00f6neminde yak\u0131ndan izlenmelidir.<\/p>\n

HFO yak\u0131tla g\u00fcvenli ve ekonomik i\u015fletme, do\u011fru \u00fcr\u00fcn\u00fc bulmaktan daha fazlas\u0131n\u0131 gerektirir.
