INTERNAL TREE CAP AND ITC RUNNING TOOL |
摘要 |
<p>Internal tree cap (201) (ITC) adapted to be installed in the bore of a subsea well unit (301) or to an internal tubular element (303) of the same, comprising a locking element (209) for releasably locking the internal tree cap (201) to said subsea well unit (301) or internal tubular element (303). The ITC further comprises a fluid channel (215) extending through a fluid barrier between the lower and upper part of the internal tree cap (201), which fluid channel (215) is blocked by a burst element (217) adapted to break and open for fluid flow through the fluid channel (215) when exposed to a predetermined pressure difference over the burst element (217). The invention also relates to an ITC running tool (101) and a locking mechanism (117) for supporting the ITC in the tool.</p> |
