The Seahorse Dual Bore Selector system is used for subsea interventions, allowing a monobore riser to be used for a dual bore intervention. The system utilizes a dynamic funnel which can be shifted into one of two positions. In this way the operator can selectively have access to either the production bore or the annulus bore. The primary means of shifting the funnel is with a hydraulic control function. The backup means is through an industry standard linear override mechanism. If required, a third bore location can be accommodated.
