ABSTRACT:
A system is disclosed for retrieving a tubular element extending into a subsea well provided with a wellhead, the tubular element being provided with a hanger suspending the tubular element at the wellhead, the hanger having a larger outer diameter than the tubular element. The system comprises a conduit assembly having a passage providing fluid communication between the wellhead and an offshore platform located above the well, the conduit assembly having at least an upper part of internal diameter allowing the tubular element to pass therethrough. The system further includes disconnection means for disconnecting the hanger from the tubular element, and retrieval means for retrieving the tubular element through the conduit assembly to the offshore platform.
