PATenergy – Offshore Hydraulic Energy Recovery Concept 

PATenergy® – Offshore Energy Recovery
Innovative Pump-as-Turbine retrofit for offshore platforms and vessels. Reduce fuel costs, CO₂ emissions, and OPEX with quick ROI.

Energy recovery from offshore pump systems using Pump-as-Turbine technology.

Energy Recovery Concept

Energy Efficiency Solutions

Optimize existing energy systems to reduce fuel consumption and CO₂ emissions, achieving measurable cost savings with quick ROI.

Innovation & Retrofit (PATenergy®

Convert pumps into turbines with our PATenergy® retrofit. Integrated with VFDs, control systems, and optional battery storage for maximum efficiency.

Energy Recovery Concept

Hydraulic energy in many offshore pump systems is currently dissipated through throttling valves, pressure reduction or gravity discharge.

PATenergy focuses on recovering part of this energy using Pump-as-Turbine technology.

Offshore Applications

Typical offshore applications include deepwell pumps, ballast systems, cooling water circuits and other pump systems where hydraulic energy is currently lost.

PATenergy aims to convert these energy losses into useful electrical power.

Energy recovered from pump systems could support hybrid vessel architectures and battery systems used on modern offshore vessels.

The Problem

 

 

  • Offshore platforms face increasing energy and cost challenges:

 

  • 🌀 Pumps run 24/7 💧
    Offshore pumps consume hundreds of kilowatts continuously, day and night.

 

  • ⛽ Diesel dependency 🛢️
    High fuel costs and complex logistics drive up OPEX.

 

  • 📈 Rising fuel prices
    Global market volatility makes operating expenses unpredictable.

 

  • ☁️CO₂ emissions 🌫️
    Each platform emits thousands of tonnes of CO₂ annually.

 

  • 📜IMO & ESG regulations ✅
    Strict rules require measurable energy efficiency and emission reductions.
