Description
Foreliggende oppfinnelse vedrører en fremgangsmåte for behandling av utsiden av skips-skrog. The present invention relates to a method for treating the outside of a ship's hull.
Foreliggende oppfinnelse vedrører en fremgangsmåte for behandling av utsiden av skips-skrog for å redusere brennstoff-forbruket under fart, og det særegne ved fremgangsmåten i henhold til oppfinnelsen er at utsiden av skips-skroget behandles i en del av lengden mellom perpendikulærer gjennom stevnene tilsvarende ti til tredve prosent for å redusere overflateruheten og deretter belegges den behandlede overflate på nytt. The present invention relates to a method for treating the outside of a ship's hull in order to reduce fuel consumption during travel, and the distinctive feature of the method according to the invention is that the outside of the ship's hull is treated in part of the length between perpendiculars through the bows corresponding to ten to thirty percent to reduce the surface roughness and then the treated surface is coated again.
Når et skip har vært i fart i noen år er utsiden av skroget rustet og også forurenset av marine organismer slik at hastigheten av skipet reduseres og drivstoff-forbruket øker. When a ship has been in motion for a few years, the outside of the hull is rusted and also contaminated by marine organisms so that the speed of the ship is reduced and fuel consumption increases.
Vanligvis blir et skip i en slik tilstand reparert ved delvis å fjerne rust og de forurensende organismer ved hjelp av flekkvis sandblåsing og fornyet belegging med en anti-korroderende og anti-gromaling på det flekkvis sandblåste område. Usually, a ship in such a condition is repaired by partially removing the rust and the polluting organisms by spot sandblasting and recoating the spot sandblasted area with an anti-corrosive and anti-fouling paint.
På bakgrunn av den meget høye pris på derivstoffolje ogAgainst the background of the very high price of derivative oil and
på bakgrunn av det forhold at den flekkvise sandblåsings-reparasjon har noen virkning, men resulterer i høyt drivstoff-forbruk under fart etter reparasjonen, har det vært vanlig at skipet settes i tørrdokk etter å ha vært i drift i en gitt periode og deretter blir hele den neddykkede utside av skroget sandblåst for å fjerne rust og marine organismer og deretter belegges hele den behandlede flate med anti-gromaling, men andre ord at skipet utsettes for systemet med full sandblåsing og belegging med anti-gromaling. on the basis of the fact that the patchy sandblasting repair has some effect, but results in high fuel consumption during speed after the repair, it has been common for the ship to be put into dry dock after having been in operation for a given period and then the whole the submerged exterior of the hull is sandblasted to remove rust and marine organisms and then the entire treated surface is coated with anti-fouling paint, but in other words the ship is subjected to the system of full sandblasting and coating with anti-fouling paint.
I dette tilfelle kan drivstoff-forbruket reduseres, menIn this case, fuel consumption can be reduced, but
da et stort areal av utsiden av skroget behandles er denne reparasjon dyr. as a large area of the outside of the hull is treated, this repair is expensive.
Den foreliggende oppfinnelse tilveiebringer en fremgangsmåte for behandling av utsiden av skips-skrog for skip som er i fart og som tillater drivstoff-besparelser ekvivalente med besparelsene i tilfellet av behandling av hele overflaten og som likevel er forholdsvis grei og billig. The present invention provides a method for treating the outside of ship's hull for ships in motion which allows fuel savings equivalent to the savings in the case of treating the entire surface and which is nevertheless relatively simple and inexpensive.
Utsiden av skroget kan behandles ved hjelp av f.eks. kontinuerlig eller avbrudt blåsing med sand, våt sand eller grus for å redusere overflateruheten. The outside of the hull can be treated using e.g. continuous or intermittent blasting with sand, wet sand or gravel to reduce surface roughness.
Sandblåsemetoden foretrekkes for å oppnå en glatt blåst overflate i løpet av en forholdsvis kort tidsperiode. The sandblasting method is preferred to achieve a smooth blasted surface within a relatively short period of time.
Som grunningsmaling for den fornyede belegging anvendes klorert gummi, tjærevinyl, tjæreepoksy etc, men systemer med tjærevinyl og tjæreepoksy foretrekkes. Chlorinated rubber, tar vinyl, tar epoxy etc. are used as primers for the renewed coating, but systems with tar vinyl and tar epoxy are preferred.
Med hensyn til anti-gro-topplaget kan klorerte vinyl-malinger og organiske polymer-malinger påføres, men selvpolerende anti-gromalinger foretrekkes. With regard to the anti-fouling top layer, chlorinated vinyl paints and organic polymer paints can be applied, but self-polishing anti-fouling paints are preferred.
Et eksempel på anti-gromaling av selvpolerende type er tributyl-tinn(meta)akryl-copolymer-maling. An example of self-polishing type antifouling paint is tributyl tin (meta)acrylic copolymer paint.
Det er nevnt at et redusert areal av utsiden av skroget behandles og belegges på nytt. Til tross for det reduserte behandlingsareal er det mulig å oppnå vesentlige drivstoff-besparelser og dette muliggjøres også av en kort reparasjonsperiode i dokken samtidig som man oppnår fordelen fra økning i fartstiden med en stor nedsettelse av reparasjonsomkostningene i sammenligning med det fullstendige behandlings-beleggings-system. It is mentioned that a reduced area of the outside of the hull is treated and recoated. Despite the reduced treatment area, it is possible to achieve significant fuel savings and this is also made possible by a short repair period in the dock while at the same time achieving the benefit from an increase in sailing time with a large reduction in repair costs compared to the complete treatment-coating system .

Skip somvist i den etterfølgende tabell 1 ble satt i fart for en viss tidsperiode og deretter ble deler av utsiden av skips-skrogene vist i tabell 1 behandlet ved hjelp av sandblåsing og anti-gromaling som vist i tabell 1 ble påført de sandblåste overflatearealer. Ships as shown in the following table 1 were put into motion for a certain period of time and then parts of the outside of the ship's hulls shown in table 1 were treated by means of sandblasting and anti-fouling paint as shown in table 1 was applied to the sandblasted surface areas.
Den gjennomsnittlige overflateruhet av de behandlede skrog-overflater før og etter behandling var som anført i tabellen. The average surface roughness of the treated hull surfaces before and after treatment was as stated in the table.
De behandlede og malte skip ble så satt i fart i perioder vist i tabell 1. Verdier for kl/sjømil før overflatebehandling, kl/sjømil etter overflatebehandling og prosentvis reduksjon av kl/sjømil for disse skip ble oppnådd. Resultatene er vist i tabell 1. The treated and painted ships were then put into motion for periods shown in table 1. Values for hours/nautical mile before surface treatment, hours/nautical mile after surface treatment and percentage reduction of hours/nautical mile for these ships were obtained. The results are shown in table 1.
