Lined clamp for hoses and control lines

Abstract

A clamp with liner and mounting base are provided for the attachment of control lines to a subsea riser. The clamp comprises an upper clamp half and a lower clamp half. Each clamp half is hingedly connected along a hinge edge of each clamp half to the other clamp half and latchably connected along a latch edge of each clamp half to the other clamp half by latch structure carried by each clamp half. The latch structure carried by the upper clamp half comprises a pair of parallel ears protruding transversely away from the latch edge of the upper clamp half and defining a pair of aligned boreholes, a pivot pin having a transverse borehole carried by the aligned boreholes through the ears, a bolt carried in the transverse borehole through the pivot pin, and a toggle bar having a threaded transverse borehole therethrough threadably mounted on the bolt. The latch structure carried by the lower clamp half comprises a pair of parallel ears protruding transversely from the latch edge of the lower clamp half and defining a pair of saddles facing away from the upper clamp half and contoured for close receipt of the toggle bar. Each clamp half has an inner surface defining a laterally bounded depression for receiving and locating a liner element having a portion shaped to fit the depression.
