Swivel flange
Swivel flanges, as shown in Figure 39, are a particular type of connector that offers the advantage of relative rotation between the connector and the vessel to aid installation operations. Quick-disconnect and quick connect-disconnect systems may be used as connectors where emergency release is an operational requirement for dynamic riser applications.
