  • Arcuate control line encapsulation
    Patent number: 8430167
    Abstract: Control lines on the outer surface of a tubular disposed within a drilling riser casing may be encapsulated to facilitate formation of a seal in an annular space defined by an inner surface of the drilling riser casing and an outer surface of the tubular. More specifically, an encapsulation body may be configured to at least partially encase control lines. The encapsulation body may include a first surface and a second surface. The first surface may have an arcuate shape that corresponds to the outer surface of the tubular to facilitate formation of a seal between the first surface of the encapsulation body and the outer surface of the tubular when the first surface of the encapsulation body abuts the outer surface of the tubular. The second surface may be shaped to provide a geometrically continuous periphery about the tubular and the encapsulation body when the first surface of the encapsulation body abuts the outer surface of the tubular.
