Abstract
Disclosed is a pipe-in-pipe apparatus comprising an inner pipe disposed within an outer pipe wherein the inner pipe is an engineered pipe or umbilical. The outer pipe will shield the inner pipe. As a result, the design of the inner pipe only needs to address the functions required for the engineered pipe-in-pipe apparatus. The end fittings of the system are designed for enabling maximum operation and intervention flexibility. The engineered pipe-in-pipe apparatus will allow longer sections of the inner pipe to be used which will reduce the amount of field fabrication and streamline the installation process. The apparatus may be used for both new piping systems as well as the updating or retrofitting of an existing onshore or offshore piping system.
