Abstract
A load limiting break away arrangement for a subsea umbilical includes telescoping inner and outer bodies. The inner body includes multiple cross-bored holes; the outer body has slotted openings on its top and bottom sides. A shearing blade is positioned at one end of a top slot of the outer body. Individual umbilical tubes pass through a bottom slot of the outer body, through individual holes in the inner body and out a top slot of the outer body for attachment to multiple quick connect couplers on an umbilical termination head of an Umbilical Termination Assembly (UTA) and of an Electro-Hydraulic Distribution Module (EHDM). Tension resistant actuation members run between the UTA and EHDM so that when a snag of an umbilical occurs, the inner and outer bodies are pulled apart and the tubes are severed one by one by the blade of the outer body.
