Sliding subsea electronics module chassis

Abstract

A subsea electronics module (SEM) is disclosed. The SEM includes a first axis and a second axis, the first axis being longer than the second axis. Electronic modules are mounted on at least one movable platform which is aligned to move in a direction of the first axis of the SEM. External electrical outlets are mounted on a body and along the first axis of the SEM. The external electrical outletsprovide electronic coupling between the electronic modules and components of a lower marine riser package (LMRP).

Problems solved by technology

However, maintenance and repair of such SEMs requires heavy equipment to completely remove the SEM from the LMRP prior to removing the electronics module for any work to be performed

Furthermore, since the SEM is configured as a vertically mounted cylinder, the removal process is time-consuming, error-prone, dangerous, and can result in damage to the electronics module in the process
