Features and benefits
how it works
An example of use :
The Break Away Sub is mounted inline a control line of a typical Fail-Safe Closed valve. The Break Away Sub is hung off on the subsea structure with a wire. During drift off the hose will take up a straight-line position from the wire hang-off point to the vessel. At a certain tension, the Break Away Sub will separate without introducing loads to the valve.
