Abstract
Abstract Apparatus for conveying hydraulic fluid under pressure past a telescoping slip joint type subsea bumper sub including three conduit support collars with the first support collar and the second support collar rigidly mounted to a first section of the bumper sub and with the third support collar rigidly mounted to a complementary second section of the bumper sub. A rigid conduit is mounted in fluid conveying relation to the third support collar and mounted in reciprocating relation with the second support collar. A flexible conduit is mounted to the first support collar in fluid conveying relation and connected to the rigid conduit in fluid conveying relation. The flexible conduit means is formed and shaped to continually exhibit a coil configuration disposed about the bumper sub between the first collar and the second collar.
