Abstract
En 中文
Subsea production systems technologies are being developed steadily to address the technological issues associated with the deep-sea environment, primarily pressure, and temperature. To ensure the reliable operation of electrical/electronic systems for at least 25 years on the seabed, a comprehensive technology qualification program is proposed in this article. In relation to this, technology readiness level of the subsea electrical/electronics assembly is achieved after conducting devised environmental stress tests compliant to the internationally recognized standards, e.g., API, ISO, IEC, and IEEE. The comprehensive tests methods of the qualification program are explained to achieve the technology readiness level 3 of the subsea printed circuit board and subassemblies. Finally, experimental test results of a standalone subsea Ethernet switch and also functional verification with 100 m of electrical flying lead undergoing the prescribed test methods show that the subsea electronics comply with the international standards and is fit for use in the subsea environment.
