ABSTRACT:
Apparatus for performing drilling operations and for servicing an underwater well from a surface installation comprises a main string that is removable from the top of the wellhead in a way that is totally independent of auxiliary hoses which are hoses suspended from the surface installation independently of the main string and at a distance from it, from separate elements making possible the continuous advance of the hoses. The length of the hoses is adjusted in service so that they form, in the water, a plurality of catenaries supported by the surface installation and connected to the top of the wellhead with interposition of curvature-limiting elements.
