Abstract

Fremgangsmåter og apparater for marinrørleggingsoperasjoner er beskre- vet, i hvilken røret som skal legges ut blir matet fra en oppbevaringsspole (18), over en bøyningssko (20) montert på en tårnstruktur (12) plassert over en underdekksåpning (14) gjennom en utret- tingsenhet (22) som er opphengt fra tårnstrukturen (12) og inn i vannet via underdekksåpningen (14). Rørledningen blir rettet ut ved at den mates stykke- vis fra spolen, og blir klemt mens ut- rettingsanordningen trekkes oppover langs en lengde av rørledningen som strekker seg mellom bøyningsskoen og underdekksåpningen. Systemet som beskre- vet egner seg for bruk i et boreskip som kan midlertidig omformes for rørleg- gingsformål.Methods and apparatus for marine plumbing operations are described in which the pipe to be laid is fed from a storage coil (18), over a bending shoe (20) mounted on a tower structure (12) positioned above a lower deck opening (14) through an upright suspension unit (22) which is suspended from the tower structure (12) and into the water via the lower deck opening (14). The pipeline is straightened by feeding it piece by piece from the coil, and is squeezed while the straightening device is pulled upward along a length of the pipeline extending between the bend shoe and the lower deck opening. The system described is suitable for use in a drilling vessel that can be temporarily transformed for plumbing purposes.
