Abstract:
A bore selection device for use with a dual bore subsea system is disclosed. The bore selector (18) can be remotely actuated to provide selection between a production bore (12) and an annulus bore (16) without a rotating mechanism or flapper valve. Embodiments of the invention are disclosed. In one embodiment a pair of rams (20) having a ram head (20a, 20b) defining parts of a guide funnel (30a, 30b) are hydraulically actuatable so that when the rams are actuated and closed the guide funnel (30) is formed which couples a part of the production bore (126) to the annulus bore (16a).
