DG and DG-2 mandrel connector system
Mandrel connectors resemble collet connectors, but generate the sealing preload with serrated locking dogs instead of collet sleeves. Our range of mandrel products for flowline connections includes the DG and DG-2 connectors
DG connector. I s a proven design based on integral hydraulics, with operation through an ROV panel and with the seal fixed to the connector.
DG-2 connector. Is a design evolution of the DG model and accommodates subsea seal replacement. The DG-2 connector can be operated through integral hydraulics and in non-integral mode using an ROV-carried stroking mechanism.
