Latching assembly for riser pipe spacers

摘要

Means are provided for latching a Vertically Moored Platform riser spacer to the riser pipes which connect a floating platform to a subsea anchor. This includes a spring loaded latch pin recessed in a hole in the riser donut housing which surrounds the riser and which is released by pulling a spring loaded latch release pin to let the latch pin move outwardly to a latched position where it is held in this position by a spring loaded shear pin. To disengage the latch pin, a hydraulic ram or other means can be used to shear the retaining pins and remove the latch pin.
