One of the large breakthroughs in the O&G industry is the complete electrification of the completion. In this regard, a whole new group of equipment has been developed for implementing electric completion. One of the most critical is the subsea interface (SI), with the role of providing the subsea valves with the necessary power and the communication layer to the topside instrumentation and control. In order to evaluate the reliability of the SI, a complete test protocol must be designed, encompassing mechanical, thermal, electronic and electrical testing, since the equipment involves different mechanical support parts, power electronics and communication devices. In this work, the elaboration of a test protocol for the SI is executed according to the most recommended guidelines, academic research and reliability considerations.
