Abstract
Official abstract text for this publication.
A subsea system includes an electrically powered control system for controlling the subsea system and a replaceable reserve battery electrically coupled to the control system to provide backup and/or supplemental power to the control system when the reserve battery is activated. The reserve battery is provided in a housing having a first coupling, the subsea system includes a second coupling, and the first and second couplings are detachably connectable to each other and include electrical connections so that the reserve battery is replaceable while the subsea system remains below the sea-surface.
First claim
Opening claim text (preview).
What is claimed is: 1. A subsea system comprising: an electrically powered control system for controlling the subsea system; a reserve battery electrically coupled to the control system to power the control system when the reserve battery is activated, the reserve battery remaining inert until activated; a container that houses the reserve battery, the container having a first coupling; and a second coupling, the first and second couplings being detachably connectable to eac…
