Claims (8)
1. Anodekonstruktion omfattende en ramme med to eller flere anoder og som er indrettet til at blive anvendt i forbindelse med en offshore-installation, rørledninger eller andet udstyr, til fjernforbindelse med offshore-installationen via kabelforbindelse imellem anodekonstruktion og offshoreinstallation, hvor i det mindste én anode er monteret i en fast position i rammen for anodekonstruktionen og hvor i det mindste én anode er monteret til at være bevægelig fra en transportposition til en indsætningsposition, hvor rammen omfatter en hoveddel og i det mindste én bevægelig del monteret på hoveddelen og indrettet til at være vipbar eller forskydelig i forhold til hoveddelen, hvor én eller flere anoder er monteret i en fast position på hoveddelen og én eller flere anoder er monteret på den bevægelige del, hvor hoveddelen har en bundrammedel og en toprammedel og yderligere i det mindste to anodemontagesøjler imellem bundrammedelen og toprammedelen, og hvor de faste anoder er monterede på anodemontagesøjlerne.
2. Anodekonstruktion ifølge krav 1, hvor i det mindste én anode er et aflangt element med en akse, som strækker sig igennem anoden, og hvor aksen for vipning af den vipbare rammedel er i det væsentlige parallel med aksen for anoden.
3. Anodekonstruktion ifølge krav 1 eller 2, hvor den i det mindste ene anode er et aflangt element med en akse, som strækker sig igennem anoden, og hvor aksen for vipning af den vipbare rammedel er i det væsentlige vinkelret på aksen for anoden.
4. Anodekonstruktion ifølge ethvert af de foregående krav, hvor anodesøjlerne er monterede imellem bundrammedelen og toprammedelen imellem hjørnesøjler ved modstående ender af rammekonstruktionen.
5. Anodekonstruktion ifølge ethvert af de foregående krav, hvor anodesøjlerne er hjørnesøjler imellem bundrammedelen og toprammedelen.
6. Anodekonstruktion ifølge ethvert af de foregående krav, hvor antallet af anoder monterede i faste positioner er i det mindste to, og hvor antallet af anoder monterede til at være bevægelige, er i det mindste to.
7. Anodearrangement omfattende i det mindste to anodekonstruktioner ifølge ethvert af de foregående krav, hvor de i det mindste to anodekonstruktioner er indbyrdes forbundet, eksempelvis ved svejsning, boltning eller beslagsforbindelse eller en kombination af disse.
8. Fremgangsmåde til indsætning af en udskiftningsanodekonstruktion til en offshoreinstallation, hvilken fremgangsmåde omfatter: a. tilvejebringelse af en anodekonstruktion med anodekonfiguration som angivet i ethvert af de foregående krav; b. transport af anodekonstruktionen med de bevægelige anoder i disses transportposition; c. bevægelse af de bevægelige anoder til indsætningspositionen for anodekonstruktionen; d. anbringelse af anodekonstruktionen på dennes indsætningsposition i tilstødning til offshore-konstruktionen; e. forbindelse af anoderne i anodekonstruktionen med de relevante dele af offshore-konstruktionen via elektriske forbindelser.
