SEAGLOW Eesti demonstratsioonlaev,\u00a0<\/span>PMA-605<\/span><\/i>, on saanud uue kerekatte, mis t\u00f5rjub merem\u00e4\u00e4rdumist ilma biotsiide kasutamata. M\u00f6\u00f6dunud suvel kantud t\u00f6\u00f6tlus on osa projekti tegevustest, mille eesm\u00e4rk on hinnata tavap\u00e4raste m\u00fcrkv\u00e4rvide alternatiive, p\u00f6\u00f6rates erilist t\u00e4helepanu nende m\u00f5jule mereelustikule.<\/span>\u00a0<\/span><\/p>\n

Projekti partneri Clean Ocean Coatings v\u00e4lja t\u00f6\u00f6tatud Ecoating\u00ae kasutab merelise elustiku t\u00f5rjumiseks k\u00f5va ja mittepoorset pinda biotsiidsete ainete eraldamise asemel. Selle kandmine\u00a0<\/span>PMA-605<\/span><\/i>\u00a0aitab SEAGLOW-l hinnata keskkonnas\u00f5bralikkust, vastupidavust ja hooldusn\u00f5udeid igap\u00e4evastes kalap\u00fc\u00fcgitingimustes.<\/span>\u00a0<\/span><\/p>\n

PMA-605 ettevalmistamine katsetuseks<\/span><\/b>\u00a0<\/span><\/p>\n

Argo Mengelile kuuluv,\u00a0<\/span>PMA-605<\/span><\/i>\u00a0on klaaskiudtugevdatud plastist kalap\u00fc\u00fcgilaev, mille pikkus on 11,70 meetrit ja laius 3,10 meetrit. Laev s\u00f5idab kiirusega 6\u20137 s\u00f5lme ning pakub praktilist keskkonda katte sobivuse hindamiseks v\u00e4ikesemahulises kalap\u00fc\u00fcgis.<\/span>\u00a0<\/span><\/p>\n

Laev t\u00f5steti kaldale P\u00e4rnu l\u00e4hedal asuvas Liu Paadi laevatehases (Paadimeistri). Umbes 38 ruutmeetrit veealust kerepinda puhastati ja kaeti.<\/span>\u00a0<\/span><\/p>\n

K\u00f5rgsurvepesu eemaldas esmalt merelise elustiku ja lahtised ladestused.\u00a0KL Soodaprits O\u00dc<\/a>\u00a0seej\u00e4rel liivapritsiti kere, et eemaldada olemasolevad kattekihid. Sellele j\u00e4rgnesid geelkatte kohalikud parandused, lihvimine ja puhastamine, valmistades pinna ette uue kaitses\u00fcsteemi jaoks.<\/span>\u00a0<\/span><\/p>\n

Uue katmiss\u00fcsteemi rakendamine<\/span><\/b>\u00a0<\/span><\/p>\n

\"\"Meeskond alustas viie kihi musta kahekomponentse epoks\u00fckruntv\u00e4rvi VC Tar2 kandmisega, mis on ette n\u00e4htud kere kaitsmiseks vee sissetungi ja osmoosi eest.<\/span>\u00a0<\/span><\/p>\n

Seej\u00e4rel kanti kogenud tehniku poolt spetsiaalse kahekomponentse k\u00f5rgsurve-v\u00e4rvimiss\u00fcsteemi abil peale punane Ecoating\u00ae pealiskiht. V\u00e4rvimisseadmed tarnis WIMA Verfahrenstechnik GmbH, kuna kompressoriseadmed tarnis ja paigaldas Cramo Estonia AS.<\/span>\u00a0<\/span><\/p>\n

Tulevane s\u00fcsteem \u00fchendab kaitsekrundi vastupidava pealiskihiga, mis on ette n\u00e4htud taluma korduvat puhastamist kogu oma kasutusea jooksul.<\/span>\u00a0<\/span><\/p>\n

Teistsugune l\u00e4henemine merebioloogilisele saastumisele<\/span><\/b>\u00a0<\/span><\/p>\n

Tavalised biotsiidseid aineid sisaldavad m\u00fcrkv\u00e4rvid eraldavad toimeaineid, mis takistavad organismide kinnitumist laevakerele. Need ained v\u00f5ivad m\u00f5jutada ka mereelustikku v\u00e4ljaspool organisme, mille t\u00f5rjumiseks need on ette n\u00e4htud.<\/span>\u00a0<\/span><\/p>\n

Ecoating\u00ae l\u00e4heneb asjale teisiti. Selle sile ja k\u00f5va pind on loodud nii, et mereelustikul oleks sinna raskem kinnituda, ilma et see tugineks biotsiidide eraldumisele v\u00f5i kuluvale kattekihile. Kinnitunud elustikku saab eemaldada mehaanilise puhastusega, samas kui piisav veeliikumine piki laevakere v\u00f5ib samuti toetada\u00a0<\/span>heitvesi<\/span><\/i>\u00a0efekt.<\/span>\u00a0<\/span><\/p>\n

Tavap\u00e4rase m\u00fcrkv\u00e4rviga seotud keskkonnasurve v\u00e4hendamine on selle katte katsetamise peamine motiiv SEAGLOW projektis. Seet\u00f5ttu uuritakse projekti hinnangutes mitte ainult seda, kuidas kate t\u00f6\u00f6s olevatel alustel toimib, vaid ka selle koostoimet \u00fcmbritseva merekeskkonnaga.<\/span>\u00a0<\/span><\/p>\n

T\u00f5endite kogumine reaalsetes tingimustes<\/span><\/b>\u00a0<\/span><\/p>\n

Rakendus on\u00a0<\/span>PMA-605<\/span><\/i>\u00a0t\u00e4histab pikema hindamise algust. Seire aitab kindlaks teha, kuidas kate aja jooksul toimib, kui sageli on vaja seda puhastada ja kas see pakub kalalaevaomanikele praktilist alternatiivi. See aitab luua selgema pildi sellest, kuidas v\u00e4ikesemahuline kalap\u00fc\u00fck saab kaitsta oma laevu, v\u00e4hendades samal ajal survet mere\u00f6kos\u00fcsteemidele.<\/span>\u00a0<\/span><\/p>\n
