摘要 |
Various implementations include a system for introducing upwardly a flexible member into a tubular fixed structure with a sleeve surrounding the flexible member in the region where the flexible member attaches to the tubular fixed structure. The system allows for the flexible member to be drawn upwardly into a bore of the tubular fixed structure. In one implementation, a plurality of locking dogs are attached to and are radially moveable with respect to the sleeve between an inner locking position in which they engage with the flexible member, and an outer release position in which they are disengaged from the flexible member. In addition, a latch ring is disposed on a substantially cylindrical surface so that it may be deflected axially along said surface on contact between the sleeve and tubular fixed structure to permit release of the locking dogs. |
