Abstract

Fremgangsmåte for tauing av undervanns rørledninger ved hjelp av fremre taubåter (R) for trekking og bakre taubåter for mottrekking, kjennetegnet ved at den utføres ved bruk av et sett av utstyr (A) forbundet med selve rørledningen (C), og som hovedsakelig omfatter flottører (G), av hvilke i det minste en del har variabel oppdrift eller delvis variabel oppdrift, og som når de er anbragt i en forutbestemt stilling og med forutbestemte intervaller bevirker en gradert oppdrift for rørledningen i forhold til avstanden (@ fra sjøbunnen (F), for oppnåelse av en "festoon"-utformning av rørledningen, dvs. med opphengte seksjoner av rørledning, tilsvarende flottørene, vekselvist med liggende seksjoner.
