Abstract
A connector assembly that selectively connects to a wellhead housing having a clamp type hub. The connector assembly utilizes a selectively energized clamp type connector and an internal replaceable seal assembly; the connector has clamp segments that selectively engage and secure against the clamp hub of the wellhead housing. As the connector assembly engages the wellhead housing, the internal replaceable seal member engages with the wellhead hub (and typically a seal ring thereof) to form a fluid pressure seal.
