Abstract: A subsea umbilical system can be provided for connecting a topside structure at a proximal end of the system to subsea equipment at a distal end of the system. The system can include an umbilical configured to allow one or more cables for powering or communicating with subsea equipment to be passed through at least a portion of the umbilical. The system can further include reinforcing elements radially surrounding a portion of the umbilical. The system can further include a breakout box disposed along the umbilical and configured to be positioned between the reinforcing element and the subsea equipment. The breakout box can include a breakout opening configured to allow one or more breakout cables to exit the umbilical and run along the outside of the reinforcing elements to the topside structure. Related methods of making and using such systems are also described.
