Abstract

En konstruksjon (200) for undervarmsinstallasjon har oppdrift fordelt i det vesentiige langs sin lengde for å flytetiansportere konstruksjonen i horisontal orientering til et installasjonspunkt. Når konstruksjonen blir stilt på høykant holder den fordelte oppdriften konstruksjonen i en i det vesentiige vertikal orientering og operasjonstilstand, uten behov for ytterhgere, ikke-fordelt oppdrift (for eksempel uten at vesentlig sttekk er tilveiebragt av en toppbøye eUer et overflatefartøy (100)). Konstruksjonen kan innbefatte en fleksibel eller stiv stigerørsledning for hydrokarboner. Oppdriftsmoduler kan så bh festet med meUomrom mellom dem, for eksempel for å oppnå en konstruksjon lignende en SLOR, eller eOR, men uten en toppbøye. Oppdriftsmodulene kan altemativt være fri til å gli langsgående langsmed konstruksjonen for å bibringe deres oppdriftskraft gjermom hverandre til toppen av konstruksjonen.A structure (200) for sub-heating installation has buoyancy distributed substantially along its length to move the structure in horizontal orientation to an installation point. When the structure is set upright, the distributed buoyancy keeps the structure in a substantially vertical orientation and operating state, without the need for additional, non-distributed buoyancy (for example, without substantial thrust provided by a top bend or a surface vessel (100)). The structure may include a flexible or rigid risers for hydrocarbons. Buoyancy modules can then be bra fitted with a space between them, for example to achieve a structure similar to an SLOR, or eOR, but without a top bend. The buoyancy modules may alternatively be free to slide longitudinally along the structure to impart their buoyancy power to each other to the top of the structure.
