Selecting the Right Subsea Pump for Your Application

Operator or manufacturer’s reports and published papers are reviewed and a criterion is developed for subsea pump selection.

Subsea gas compression and pumping technologies have been identified as a solution for accessing gas reservoirs that may be otherwise inaccessible or economically unfeasible to drill. Subsea stations offer a fast-track development solution with flexible, multiphase deployment and other inherent advantages. Pumping stations require a significant amount of process equipment improvements and integration solutions; however, the complete paper focuses on the rotating machinery, process pumps specifically.

Introduction

Subsea development is a relatively recent concept associated with comparatively underresearched and unqualified technologies. The technological improvements necessary are characterized by requirements for severe service, multiphase handling, excellent reliability, and minimal, low-maintenance solutions.

Operating Conditions for Subsea Pumps

Depending on the application for which the subsea pump is being used, fluid can be either a produced fluid, produced water, or raw seawater.
