Document Type and Number:
WIPO Patent Application WO/2012/076520
Kind Code:
A3
Abstract:
Riser top connector (11) connecting a jumper hub (23) to a riser hub (25). The riser hub (25) is in a riser tower assembly (7) which is provided with a first suspension part (19). The jumper end hub (23) is attached to a jumper termination structure (13) comprising a second suspension part (21). The jumper termination structure (13) is adapted to be landed on the riser tower assembly (7). The second suspension part pivots with respect to the first about a pivot axis (29). The suspension parts comprise a pivot cradle (19) and pivot shaft (21). When landed the jumper hub faces the riser hub with a distance, so that the jumper end hub and the riser hub can be joined to a coupling position by pivoting the jumper termination structure (13) with respect to the riser tower assembly (7), about the pivot axis (29).
