Downhole Equipment Suspension and Power System Background

Abstract

A subsea production system for a subsea well including a tubing hanger to suspend production tubing extending into the subsea well. Downhole equipment is locatable inside the production tubing in the subsea well. The system includes an adaptor spool including an internal bore. A suspension apparatus is supportable above the tubing hanger and within the internal bore of the adaptor spool. A power penetrator is laterally coupleable to the suspension apparatus. A suspension line is extendable from the suspension apparatus to suspend the downhole equipment. A communication line is extendable from the suspension apparatus to provide power to the downhole equipment.
