\n\t\t\t\t\t\t\u00cen perioade precum cea de acum, de criz\u0103 profund\u0103 a carburan\u0163ilor la nivel global, cu pre\u0163uri care au crescut enorm \u015fi chiar cu disponibilitate limitat\u0103, orice economie de carburant devine mult mai valoroas\u0103. Iar atunci c\u00e2nd totul are loc la scara imens\u0103 a unei nave de croazier\u0103, cu rol de feribot nocturn, precum Baltic Queen, micile \u00eembun\u0103t\u0103\u0163iri tehnice pot da economii majore de carburan\u0163i. De cur\u00e2nd, nava estonian\u0103 Batic Queen a trecut printr-un proces de modernizare \u00een \u015fantierele norvegienilor de la Kongsberg, iar modific\u0103rile discrete aplicate ei au dus la economisirea a c\u00e2te 4,5 tone de diesel la fiecare traversare a M\u0103rii Baltice.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tNava Baltic Queen opereaz\u0103 pe ruta dintre Tallinn, \u00een Estonia, \u015fi Stockholm, \u00een Suedia, f\u0103c\u00e2nd un popas \u015fi pe una din insulele Aland. Travers\u0103rile au loc nocturn, tocmai de asta nava e configurat\u0103 astfel \u00eenc\u00e2t s\u0103 ofere condi\u0163ii confortabile la bord, care se dep\u0103rteaz\u0103 de la nivelul unui feribot obi\u015fnuit \u015fi ajung p\u00e2n\u0103 la confortul unei nave de croazier\u0103, sau chiar un hotel bine cotat.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tNava m\u0103soar\u0103 212 metri lungime \u015fi poate transporta 2.800 pasageri la bord, iar viteza ei de croazier\u0103 e de 17-18 noduri, adic\u0103 \u00eentre 31,5 \u015fi 33,3 km\/h. Distan\u0163a total\u0103 a rutei e de aproximativ 380 km sau 205 mile nautice, iar traversarea realist\u0103, cu tot cu stopul de pe insul\u0103 \u015fi manevr\u0103rile din port, dureaz\u0103 16-18 ore, \u00een func\u0163ie de condi\u0163iile meteo. Iar la bord pot urca at\u00e2t pasageri pe jos, c\u00e2t \u015fi cei care c\u0103l\u0103toresc cu ma\u015finile.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tAcest regim de c\u0103l\u0103torie \u00eensemna c\u0103 nava are doar c\u00e2teva ore de pauz\u0103, pentru cur\u0103\u0163enie \u015fi preg\u0103tire pentru ruta de \u00eentoarcere, oper\u00e2nd \u00eentr-un program cotidian foarte intens.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tNava e echipat\u0103 cu patru motoare diesel principale Wartsila 16V32, a c\u00e2te 16 cilindri fiecare, cu turbosuflant\u0103, \u00een 4 timpi. Ele pot opera cu motorin\u0103 standard sau cu diesel marin, iar dac\u0103 ar include toate 4 motoare \u00een ac\u0163iune, nava poate atinge \u015fi 24,5 noduri \u00een condi\u0163ii bune. \u00cens\u0103 \u00een via\u0163a real\u0103 conteaz\u0103 \u015fi eficien\u0163a, a\u015fa c\u0103 nava opera preponderent cu 3 motoare conectate, 2 motoare doar c\u00e2nd marea era lini\u015ftit\u0103 \u015fi se apropia de \u0163\u0103rm, iar 4 motoare doar c\u00e2nd erau condi\u0163ii meteo neprielnice. Partea curioas\u0103 e c\u0103 nava are un sistem diesel mecanic de transferare a puterii de la motoarele diesel c\u0103tre cele dou\u0103 elice care o propulseaz\u0103, nu unul diesel electric. Puterea combinat\u0103 a motoarelor era de 32 MW, sau pu\u0163in peste 43.500 CP.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tEi bine, estonienii le-au \u00eencredin\u0163a nava norvegienilor, pentru ca ace\u015ftia s\u0103 o studieze \u00een detaliu \u015fi s\u0103 conceap\u0103 \u00eembun\u0103t\u0103\u0163iri pentru ea. Ei au concluzionat c\u0103 elicele sunt cel mai esen\u0163ial element care trebuie \u00eenlocuit. Norvegienii au decis s\u0103 monteze noi elice, cu geometrie mai eficient\u0103. De fapt, s-au montat doar elice propriu-zise, \u00eentreg mecanicul de propulsie a lor r\u0103m\u00e2n\u00e2nd identic.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tAtunci c\u00e2nd nava a fost construit\u0103, la mijlocul anilor 2000, elicele originale au fost construite de Rolls-Royce Marine \u015fi ele aveau deja un mecanism cu unghi variabil al palelor. \u00centre timp, Rolls-Royce Marine a devenit parte din Kongsberg Maritime, a\u015fa c\u0103 acum norvegienii au perfec\u0163ionat propria elaborare printr-o geometrie mai bun\u0103, cu mai pu\u0163in rezisten\u0163\u0103 hidrodinamic\u0103 \u015fi o transpunere mai bun\u0103 a puterii \u00een ap\u0103.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tEi bine, aceast\u0103 modificare discret\u0103 a navei, cu noi elice cu pale u\u015for diferite ca form\u0103 a adus 4,5 tone de economie de carburant la fiecare traversare a M\u0103rii Baltice, datorate faptului c\u0103 acum nava poate opera cu dou\u0103 motoare conectate \u015fi men\u0163ine aceea\u015fi vitez\u0103 de croazier\u0103. Iar cele 4,5 tone de diesel \u00eenseamn\u0103 un consum cu 13% mai mici, or nava consuma anterior circa 35 tone de diesel pentru o traversare, iar acum consum\u0103 30,5 tone.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tNava face 7 travers\u0103ri \u00een fiecare s\u0103pt\u0103m\u00e2n\u0103, 365 travers\u0103ri pe an. Iar aceast\u0103 economie \u00eenseamn\u0103 31,5 tone economisite pe s\u0103pt\u0103m\u00e2n\u0103 \u015fi 1.642,5 tone de diesel economisit \u00eentr-un an. Transformat \u00een litri, dac\u0103 ne referim la dieselul marin \u015fi densitatea lui, asta \u00eenseamn\u0103 1.952.750 litri de diesel economisi\u0163i anual! \u00cen condi\u0163iile actuale de criz\u0103, c\u00e2nd tona de diesel marin cost\u0103 pu\u0163in peste 1.000 dolari, asta \u00eenseamn\u0103 o economie de 1.650.000 dolari anual.\n\t\t\t\t\t<\/p>\n

\n\t\t\t\t\t\tEfectul advers al noilor elice a fost reducerea nivelului zgomotului cu 8 dB, care se simte mai silen\u0163ios la bordul navei, dar \u015fi pentru viet\u0103\u0163ile maritime. Dar, desigur, marele beneficiu de aici e reducerea semnificativ\u0103 \u00een consum \u015fi emisii CO2 generate. Se pare c\u0103 uneori \u015fi modific\u0103rile discrete, dar f\u0103cute cu pricepere, pot da impact imens, deci.\n\t\t\t\t\t<\/p>\n
