SUBSEA CONTROL POD DEPLOYMENT AND RETRIEVAL SYSTEMS AND METHODS

摘要

A method for replacing a first control pod of a BOP stack includes (a) lowering a control pod exchange device subsea. In addition, the method includes (b) coupling the control pod exchange device to the BOP stack. Further, the method includes (c) transferring the first control pod from the BOP stack to the control pod exchange device after (b). Still further, the method includes (d) lifting the control pod exchange device to the surface after (c).
