Kuva "Amasezerano Mpuzamahanga y’amazi yo mu nyanja Ballast" yatangira gukurikizwa muri Nzeri 2017, ba nyir'ubwato barahamagarira isosiyete ikora ibijyanye n’amato yo muri Finilande n’ubwubatsi bwo mu nyanja gukora isuzuma ryigenga rya gahunda yo guhindura amazi ya ballast. Mu mezi ashize, imikono yongewe mu masezerano mpuzamahanga yo mu 2004 agenga kugenzura no gucunga amato ya Ballast Amazi n’ibimera. Ibi ntibishobora guhisha ko ibyo byahagaritswe n’umuryango mpuzamahanga w’amazi (IMO) kuva yashingwa. Ibihugu 52 byasinyanye amasezerano na IMO byarenze 30 byasabwaga, ariko bingana na 35.1441% bya tonnage yisi yose, birenze gato 35% byateganijwe kugirango itangire gukurikizwa amezi 12 nyuma yo kubyemeza. Birasa nkaho "inyandiko" yemewe n'amategeko iri hafi, ariko biracyari umurimo woroshye. Icyakora, mu 2016, nyir'ubwato yasize iki kibazo wenyine, kubera ko yizeraga adashidikanya ko imikorere myiza ya BWMS y’amato yari ikeneye byihutirwa ibisubizo bya tekiniki. Foreship, isosiyete ikora ibijyanye n’ubwubatsi n’isosiyete ikora ubujyanama mu nyanja, iherutse gutanga ibyifuzo birambuye kubyerekeye retrofit, kandi ubushakashatsi bushoboka bukubiyemo ubwato bumwe. Sosiete yo gutondekanya isuzuma ibisubizo bitandukanye bya tekiniki hamwe nikoranabuhanga risa ritangwa nabaguzi batandukanye kubwoko butandukanye n'imyaka yubwato, kandi bagasuzuma imirimo rusange yo kwishyiriraho, aho yashyizwe, hamwe nigihe gito kandi gihoraho. Olli Somerkallio wahoze ayobora ishami ry’imashini, yasobanuye ko nubwo guhitamo hagati ya sisitemu bizayoborwa rwose n’ibiciro, ntibyoroshye kubigereranya. Somerkallio ati: "Twibanze ku bijyanye na tekiniki yo kwishyiriraho, bivuze ko hakenewe ibikoresho, amazi n'amashanyarazi." "Kugira ngo ubone ibisubizo bifatika, ukeneye ubuhanga mu bijyanye n’ubwubatsi bw’amato, ubwubatsi bwo mu nyanja, n’imyitwarire y’ubwato." Igipimo cy’amazi y’amazi y’umudugudu asabwa kuba munsi ya 500m3 / h, bigatuma ba nyir'ubwato bahitamo ikoranabuhanga rya BWMS rishingiye kuri UV, rituma amoko atera “adashoboka” aho kuyica. Ariko, nkuko byavuzwe cyane, Ingabo z’Amerika zirinda inkombe ntizigeze zemeza ibipimo by’ibizamini bya UV. Byongeye kandi, ibikoresho bya UV ntibishoboka kubipimo binini bitemba bisabwa na sisitemu nkuru y’amazi ya ballast ku mato manini atwara imizigo (nka tankeri ya peteroli hamwe n’abatwara ibicuruzwa byinshi). Hano, amashanyarazi (EC) yabaye igisubizo cyatoranijwe. EC itanga imiti yica udukoko twa chlorine inyuza amazi mu buryo butaziguye mu mazi kugirango itere reaction hamwe na chloride ya sodium. Chlorine yubusa yakozwe yica bagiteri nizindi mikorobe mu bigega bya ballast. Mu cyiciro cyo gukuraho, ibipimo bya chlorine birapimwa kandi bitagira aho bibogamiye. Ba nyir'ubwite bagomba kumenya ko imiyoboro yinyongera isabwa na BWMS, ibikoresho bifitanye isano na valve, hamwe na BWMS ubwayo nisoko yo gutakaza igitutu. Somerkallio yerekana ko pompe ya ballast igomba kuba ifite umuvuduko uhagije wo kubikemura. Yavuze ko ejo hazaza hasesengura isesengura ry’igitutu igice cy’inyigo yacyo kuko rimwe na rimwe biba ngombwa kuzamura moteri cyangwa moteri. Yavuze ati: "Mu bihe bibi cyane, pompe yose irashobora gusimburwa." Somerkallio yavuze ko hagomba no kwitabwaho bidasanzwe kuri tankeri, kubera ko amazi ya ballast akorerwa ku muheto no mu cyuma icyarimwe. Ibigega bya ballast kuruhande rwinyuma byuzuye bitatu bya kane byuzuye bityo rero ni ingenzi kumugezi utambutse. Hano, pompe nyamukuru ya ballast iherereye mucyumba cya pompe yamavuta yimizigo (ahantu hashobora guteza akaga), ntabwo rero ishobora gukoreshwa mu kuvoma amazi mumatara yinyuma ahantu hizewe. Pompe yinyuma ntishobora guhuzwa na BWMS nkuru. Ikigega gisanzwe cya peteroli yo hagati irashobora gusaba urujya n'uruza rwa sisitemu ya ballast kuba 2000 m3 / h, kandi igabanijwemo ibyambu hamwe na tanki ya ballast. Ibi birashobora gukemurwa na BWMS ebyiri zifite ubushobozi bwa 1000m3 / h, cyangwa muguhuza pompe zombi na BWMS imwe ya sisitemu imwe yo gutunganya. Umuntu ku giti cye akeneye amazi ya ballast azakemurwa na pompe ya serivise rusange ihujwe na BWMS ntoya ifite umuvuduko wa 250-300m3 / h (urugero). Ubushakashatsi bwa Foreship bushoboka bwa vuba bwasuzumye muburyo burambuye ibisubizo bibiri bya EC bitangwa nabanywanyi bahanganye: imwe ifata EC mubicuruzwa byingenzi; kurundi ruhande, EC iboneka kumugezi kandi "ibintu bya chimique" byinjijwe muri tank ya Ballast. Somerkallio yavuze ko, mubyukuri, sisitemu nyamukuru yoroshye, yoroshye, kandi ntoya kuruta sisitemu yo gutembera, kandi ikoresha amashanyarazi hafi 25%. Icyakora, yongeyeho ko ibiranga bijyanye no kwishyiriraho, imikorere n'umutekano bishobora kwemeza kubogama kubogamye. "Nk'urugero, nk'uko uwabikoze abivuga, kubera igishushanyo mbonera cya electrode n'ibikoresho, sisitemu nyamukuru ya EC irashobora gukorera ku munyu muke cyane, ariko ntishobora gukorera mu mazi ya zeru hafi ya zero nk'ikiyaga kinini cy'umunyu. Ibyo bibujijwe ntibikwiriye kunyura mu nzira. sisitemu niba umunyu uri munsi ya 15 PSU, amazi yo mu nyanja yabitswe arashobora gukoreshwa. " Ugereranije na sisitemu nyamukuru, sisitemu yo gutembera irashobora kandi gukorera mumazi akonje. Na none kandi, ingano ya sisitemu yo ku ruhande irashobora kuba inshuro ebyiri iyo sisitemu nyamukuru, kandi uburemere bwiyongereyeho 60%, ariko Somerkallio yerekanye ko ari ngombwa kubaza aho BWMS yiyongereye ifata umwanya. Yasobanuye ko kugenda kwimbere muri sisitemu nyamukuru bisaba inzu nini yinyongera kubice bibiri bya EC hamwe na filteri ebyiri, mugihe igisubizo gito cyo gutembera kumurongo kizana inyungu nyinshi kubice bya EC nibindi bikoresho bifasha. Umwanya wubwisanzure. Kubijyanye n'umwanya wo hasi, ibisubizo nyamukuru birashobora gusaba bibiri bya gatatu byahantu hasabwa kubisubizo bitemba kuruhande, ariko niba sisitemu imwe yo gutembera kuruhande ikora pompe ebyiri, itandukaniro ni ntangere. Mu buryo busa nabwo, umubare wimiyoboro isabwa kugirango EC itandukane isabwa na sisitemu yo kuruhande ikubye kabiri iyimikorere ya sisitemu. Nyamara, inyinshi mu miyoboro yinyongera ni ntoya muri diameter (DN20, DN40). Somerkallio yavuze ko nubwo yongeyeho ibitekerezo rusange bijyanye no gushyiramo tanker, izi mpinduka zemeje ko hagenzurwa neza ibikenewe ku mato ku giti cye. Ntakibazo cyakenewe kuri sisitemu nkuru, ikigega cyinyuma gikeneye gahunda itandukanye. Urashobora gutekereza gushiraho sisitemu ya UV cyangwa EC itandukanye kuruhande, ariko urashobora kandi gukoresha igisubizo cya EC mubwato bwose, kuburyo ushobora kwemeza ko intera ndende ya pompe yitaruye hagati ya sisitemu nkuru na sisitemu yinyuma. Mugihe cyanyuma, "imiti" ikorerwa ahantu hizewe izagabanywa ukundi kuri sisitemu yo kubika impanuka. Somerkallio yerekanye ko ubwoko bwose bwa sisitemu ya EC itanga hydrogène nkibicuruzwa biva mu mahanga, yongeraho ko ubwo buryo bwo guhitamo impande zombi bizana ingaruka nyinshi: mu gihe umwuka uhumeka nabi, ushobora kuvanwa mu kigega cya chlorine binyuze mu guhumeka ku gahato. Hydrogen yikubye BWMS. Icya gatatu, abakoresha bashira imbere kubungabunga bagomba gutekereza ko nubwo sisitemu nyamukuru isanzwe itagoranye, bivuze ibice bike, BWMS ebyiri zitandukanye zishobora gukenerwa: muri rusange, umubare wibigize uzaba mwinshi. Byongeye kandi, Foreship yavuze ko sisitemu nyamukuru isuzuma muri rusange ikunze kwangirika mugihe kirenze seriveri nyamukuru. Ibinyuranye, sisitemu zombi zisaba gusimburwa buri gihe, ariko nyuma yamasaha 2500, pompe zo kumpande na blowers zikeneye kwitabwaho. Nubwo imirimo myinshi ishobora gukorwa n'abakozi, Somerkallio yavuze ko isuzuma ryuzuye ryo kubungabunga muri kariya gace rigikomeje. Igihe nyir'ubwato yahuye n'ukuri kw'ikoranabuhanga ryo guhindura, yavuze ko ubushakashatsi burambuye bwakozwe na Foreship bwerekanye ko inyungu zose muri BWMS zishobora kuba zikomeye cyane mu bahari.
