Patentkrav
1. Fremgangsmåte ved installasjon av en offshore transformatorsammenstilling (10) med et effektområde over 10 eller sågar 20 MVA og/eller en masse på mer enn 50 metriske tonn, på en offshore hovedstruktur (101) som strekker seg vertikalt fra en avstand under havoverflaten (103) til en avstand over havoverflaten, og som omfatter en transformator-landingsseksjon (105) ved en avstand under havoverflaten,
hvorved offshore transformatorsammenstillingen (10) omfatter en innkapsling (13) og en transformator (11) inne i innkapslingen, primærkabler (19a) er koblet til en primærside av transformatoren og sekundærkabler (19b) er koblet til en sekundærside av transformatoren, primær- og sekundærkablene (19a, 19b) strekker seg ut av innkapslingen gjennom en innkapslingsåpning (17), hvorved offshore transformatorsammenstillingen (10) ytterligere omfatter en kanal (15) som er anordnet med en tett forbindelse til innkapslingsåpningen (17), hvorved primær- og sekundærkablene strekker seg fra transformatoren (11) og oppover gjennom kanalen (15), og i det minste til en utgangsport (27a, 27b) ved en vertikal avstand over transformatoren, hvorved fremgangsmåten omfatter de følgende trinn:
a) å transportere offshore transformatorsammenstillingen (10) med en flytende transportanordning (200), slik som et fartøy eller lekter, til lokasjonen til offshore hovedstrukturen til havs, hvorved offshore transformatorsammenstillingen (10) er anordnet ved et første vertikalt nivå under nevnte transport;
b) etter trinn a), å lande offshore transformatorsammenstillingen (10) på transformator-landingsseksjonen (105), og slik senke offshore transformatorsammenstillingen (10) til et andre vertikalt nivå som er lavere enn det første vertikale nivået;
c) etter trinn a), å koble tørrkoblingskonnektorer (23a, 23b) til offshore transformatorsammenstillingen (10) med tørrkoblingskonnektorer til offshore hovedstrukturen (101) i en posisjon over havoverflaten (103),
karakterisert ved at trinn a) omfatter å transportere offshore transformatorsammenstillingen (10) med transformatoren (11) i en posisjon under havoverflaten (103) og med den øvre delen av kanalen (15) i en posisjon over havoverflaten.
