摘要
A reentry system for a subsea apparatus or station including a normally retracted guide post, which is extendable above the well apparatus for connection to a single guide line. A frame structure lowered along the single guide line includes a gimbal mounted guide funnel assembly which provides self-adjustment of the funnel assembly during a non-axial approach into axial alignment with the guide post means. The guide posts means and funnel assembly are provided with orientation and positioning means for the frame structure so that well equipment carried by the frame structure is positioned in alignment with its cooperable part on the well apparatus. A retractable, extendable guide post which is non-rotatable and which is recoverable for maintenance and service. A method of making such a reentry to a subsea well apparatus.
