RISER GANTRY CRANE

The prime function of the riser gantry crane is to move the riser from its storage position and place it on the catwalk machine and vice versa.

Each crane comes with an integrated hydraulic power unit and either a control cabin or wireless remote radio control.

There are two main types of riser gantry crane

1. Fixed main hoists for dedicated riser handling and travelling auxiliary hoists for general use. Picture reference sedcocrane 03
2. Travelling main hoists for handling all tubulars using interchangeable heads. Picture reference RGC First Up 1

Typical Technical Data

RISER SKATE

The riser skate takes the riser, delivered by the riser gantry crane, and presents it at the well centre. The riser is supported by fixed forward supports and a travelling aft support trolley with a pivoting bucket. The skate is driven by rack and pinion to engage the riser lifting tool. As the riser is lifted away, the aft support trolley travels along the skate to support the aft end. The process is reversed when laying the riser down.
