The Research of Subsea Electronic Module for Subsea BOP

In the deepwater semi-submersible platform, the multiplexed electro-hydraulic (MUX) control system is typically used in the deepwater subsea blowout preventer (BOP) stack. In this paper the system architecture and the subsea electronic module (SEM) spatial layout for the MUX control system are presented, and the SEM housing is designed and the finite element model of the housing is built by using ANSYS software. The analysis results show the designed SEM housing can work well under 30MPa external hydrostatic pressure.
