Abstract

Oljeplattformkonstruksjon (10) for brønnarbeider på dypt vann til havs og omfattende et plattformunderstell (12), et overflatetårn (28) og et plattform- dekk (32) som bæres av understellet (12) og strekker seg opp over vannflaten (30). Videre omfatter et støtteelement (26) øverst på understellet (12) og innrettet for opptak av en oppjekkplatt- form (34) for brønnarbeider. Konstruk- sjonen (10) har fortrinnsvis totrinns pælestyrerør (20) ved bunnen slik at man etter fjerning av et sekundærtrinn i styrerøret beholder et primærtrinn for ny installasjon, hvorved gjenbruk av konstruksjonen lettes. Den fjernbare montering av en oppjekkplattform (34) på en gjenbrukbare konstruksjon (10) øker fleksibiliteten med hensyn til feltut- vinning i dype havområder.Oil platform construction (10) for deep water offshore wells comprising a platform chassis (12), a surface tower (28) and a platform deck (32) supported by the chassis (12) and extending over the water surface (30). Furthermore, a support member (26) comprises at the top of the chassis (12) and arranged for receiving an jacking platform (34) for well work. The structure (10) preferably has two-stage pile guide tubes (20) at the bottom, so that after removing a secondary step in the guide tube, a primary stage is retained for new installation, thereby facilitating reuse of the structure. The removable mounting of an jacking platform (34) on a reusable structure (10) increases the flexibility of field recovery in deep sea areas.
