A diverter for redirecting drilling fluid in oilfield applications includes a support housing and a diverter body disposed therein. A lateral opening defined in the diverter body permits fluid communication between an interior passage of the diverter body and a lateral now outlet defined by the support housing. A pair of flow-line seals disposed radially between the support housing and the diverter body includes a flow-line seal disposed on axially upper and lower sides of the lateral flow outlet. The flow-line seals include a pair of substantially rigid support rings and first and second sealing bodies adhered thereto. The first sealing body is affixed to an inner diameter wall of the first and second support rings and extends to axially upper and lower walls of the support rings. The second sealing body is bonded axially between the support rings.

A cap is lowered onto and secured to a subsea member with an external flange, effecting a seal between the external flange and cap. The cap includes a tubular outer body defining a cavity, and a tubular inner body defining a bore, wherein the lower end of the inner body resides within the cavity. The cap also includes a lower engaging member coupled to the outer body that is radially movable between an inward state and an outward state and configured to alternately engage and disengage at least one of a backside of the external flange. Finally, the cap includes an upper engaging member coupled to the outer body and being radially movable independently of the lower engaging member between an inward state and an outward state and configured to engage and disengage the inner body.

A connector is lowered onto and secured to a subsea member, effecting a seal between subsea member and the connector. The connector includes an outer body defining a cavity, and an inner body defining a bore, wherein the lower end of the inner body resides within the cavity. The connector also includes an engaging member coupled to the outer body and adapted to engage the subsea device, the engaging member radially movable between a disengaged position and an engaged position. The connector includes a seal carried by the inner body and adapted to form a seal between the bore and the subsea device. Finally, the connector includes a pre-loading member coupled to the outer body, operable to urge the inner body and seal against the subsea device to exert a pre-loading force on the seal. A differential pressure between the bore and a subsea environment energizes the seal.

A line termination assembly for a riser string has a ring adapter mounted to a slip joint and a ring body mounted on top of the ring adapter. The ring adapter radially aligns with the ring body, which forms an inner diameter for receiving the slip joint. The ring body also has a discontinuity for radial access to the inner diameter, such that the ring body is circumferentially discontinuous. The discontinuity defines a chord dimension that exceeds the outer diameter of the slip joint, such that the slip joint may move radially through the discontinuity and into the inner diameter during assembly and disassembly of the system. Fluid bearings and tension rings are mounted to the slip joint and are axially spaced apart from the ring adapter and the ring body.
