PLATFORMSFORANKRING TIL EN FLYDENDE PLATFORM MED TRAEKFORSPAENDTE FORTOEJNINGSELEMENTER.

摘要

An anchoring structure (30) for a tension leg platform (10) provides for a well template (40) which is elevated above the anchor templates (32) at a level which aqualizes the lengths of the mooring elements (26) and the well risers (36). The well and anchor templates are constructed in a unitary structure (30) to facilitate installation and ensure proper spacing of the templates (32, 40) with respect to each other. In preferred embodiments of the invention, subsea storage is provided as well as curved conductors which facilitate angular deviation of the wellbores away from the template and J-tubes for the pull-in of subsea flowlines.
