FPSO

Guide to FPSO Topside Process Modules Fabrication

February 25, 2020 Welcome

Offshore sub-sea oil & gas wells are highly productive in the modern Oil and Gas industry. According to the U.S. Energy Information Administration, offshore oil & gas production has accounted for about 30% of global crude oil production over the past decade.

Semi-submersible platforms, fixed platforms, spar platforms, tension leg platforms, and FPSOs are used extensively to harness the offshore oil & gas.

What Does FPSO Mean in Oil and Gas?

FPSOs are used most extensively for deepwater offshore oil & gas production.  FPSO stands for Floating Production, Storage, and Offloading. The term can refer to converted VLCCs (Very Large Crude Carriers), or purpose-built vessels.  Depending on world economic conditions, VLCC conversions may present a more economical and time-saving solution.  See below for a typical FSSO with 180,000 Barrel per Day processing capacity.

Purpose of a Floating Production Storage and Offloading Unit

Floating production, storage, and offloading vessels house oil and gas processing equipment and storage. These process systems are used in the separation, storage and offloading of oil and gas to shuttle tankers or transportation pipelines that take the product onshore.

Shell was the first company to build what is today recognized as an FPSO. In 1977, the company converted an oil tanker to help with oil production and storage.

Before FPSOs were common, only shallow-water oil and gas extraction was possible. Floating storage and offloading tankers (FSOs) were used to store and transport oil and gas to land for further processing. The Production part of an FPSO is what makes these units so valuable to the O&G Industry. Process skid manufacturers engineer, design, and build FPSO equipment used for separating oil, water, and gas that help streamline the production process.

FPSO Safety

Several of the nitrogen generation and purge gas process systems onboard an FPSO help improve the safety conditions on board. By using an inert gas like nitrogen to blanket and purge potentially hazardous chemicals, explosive conditions are mitigated.

IFS Provides FPSO Topside Process Systems

FPSO topside process systems and fabrication

Integrated Flow Solutions provides process packages, mechanical packages, and Utility Packages for floating production, storage, and offloading units. Our team engineers and manufactures modular, skid-mounted, “ready-to-plug-in” equipment packages for operating under the most extreme conditions.

Look at the following process, mechanical and utility solutions available from IFS.

Process Packages

These packaged systems are at the core of what FPSOs do for the Oil and Gas Industry. Process simulation is key to selecting the most effective equipment. Our oil and gas process engineering and design services leverage the HYSYS software for conceptual design, optimization, and performance modeling of proposed solutions to meet your requirements.

Heating Equipment

Heating oil and gas is often performed to promote separation and improve the transfer of higher viscosity products. IFS offers the following heating solutions:

  • Electric Well Stream Heater Package
  • Electric Glycol Reboiler Heater
  • Heating Medium Package
  • Crude Oil Heating Systems

For example, our industrial hot oil heater, HTHO-100 is designed to store and transfer heat medium fluids used to heat your O&G process systems. The heat transfer fluids within are kept in an elevated insulated storage vessel that contributes to FPSO safety measures.

Gas Conditioning

Fuel gas conditioning is used on floating production, storage, and offloading vessels to protect your power generation and process equipment from solids, liquid slugs, and aerosols. These impurities could easily cause downtime on your vessels, making it critical to condition your fuel.  IFS offers the following Gas Conditioning solutions:

  • Fuel Gas Conditioning Package
  • Buffer Gas Conditioning Package
  • Seal Gas Conditioning Package
  • Gas Dehydration System
  • Sulfur Removal System
  • Carbon Dioxide Removal System
  • Gas BTU Reduction Systems
  • H2S Removal System

The IFS fuel conditioning system is one example of a modular process solution that can help provide dry, clean fuel to help extend your equipment life.

Nitrogen Generation

Nitrogen gas provides a fixed dew point for buffer gases, purging for export line commissioning, and reduces oxygen concentrations in high ambient temperature environments.  IFS provides the following Nitrogen Generation solutions:

  • Nitrogen Generation Package
  • Separation Gas Generating Packages
  • Purge Gas Generation Packages

The IFS skid nitrogen generator is an example of a cost-effective process solution that can help improve the safety of your FPSO.

Fuel Oil Conditioning

Diesel is commonly used to power diesel engines used for utility applications like cranes, firewater pumps, emergency generators, etc.  IFS offers the following Fuel Oil Conditioning solutions:

  • Crude Conditioning Systems
  • Diesel Conditioning Systems
  • Diesel Filtration Systems
  • Diesel Forwarding Systems

Mechanical Packages

FPSOs utilize Mechanical Packages for many functions offshore.

Oil & Gas Pumps

FPSOs utilize centrifugal & positive displacement pump packages for crude oil shipping, water injection, pigging pipelines, methanol injection, firewater, just to name a few.  IFS offers pumping package solutions for many offshore applications:

  • Wet Oil Pump Package
  • Dry Oil Pump Package
  • Pigging Pump Package
  • Equalizing Pump Package
  • Sump Tank
  • Sump Pump Package
  • Seawater Injection Pump Package
  • Seawater Injection Booster Pump Package

The crude oil pipeline pumps from IFS are packaged with the suction/discharge piping, valving, instrumentation, and controls needed to pressurize and transfer crude oil from storage to pipelines or shuttle tankers.

Injection

FPSOs utilize reliable dosing of specialty chemicals for corrosion control, foaming reduction, hydration, separation, etc.   IFS offers Chemical Injection solutions for:

  • Subsea Methanol Injection Package
  • Process Chemical Injection Package

The methanol injection package from IFS includes two metering/dosing pumps, along with the piping and instrumentation needed to support your chemical injections.

Utility Packages

  • Hot Water Washdown Clean in Place (CIP) Package
  • Hydraulic Power Unit
