Abstract
A system and process for detecting the place of leakage from umbilical hoses. This system includes an internal device (PIG) which is inserted in the hose of the umbilical cable which is leaking and external detecting equipment which is intended to identify the position of the PIG device which is already inside the umbilical. The device which is inserted in the umbilical and which is known as a PIG, is made of metal and the external detecting equipment comprises two parts: one formed by a ring which surrounds the umbilical, having a sensor system and another part which has the electronics, capable of identifying the presence of the PIG and, with this, modifying the signal, so that it can be identified. The system is presented as a process for detecting the exact place of leakage from umbilical hoses and the technology tested is easy to operate and the inspection is carried out at a good speed and continuously, without creating waste.
