FPSO stands for Floating Production Storage and Offloading Oil Tanker. The onboard equipment can receive crude oil and natural gas extracted from subsea oil wells or drilling platforms, and achieve their separation, storage, and export.

However, precisely because FPSO combines the advantages of both offshore vessels and oil and gas plants, the measurement tasks in its production must also face various challenges:

With the help of VEGA's level and pressure measurement technology, a FPSO floating storage and unloading oil tanker that has been retrofitted in China has successfully found solutions to these problems.

On FPSO ships, one of the main test media is oil, including crude oil to be processed and various hydrocarbon products. VEGA iscargo oil tankprovideOverall measurement plan, includingRadar level gauge, high-level alarm tuning fork switch, and pressure transmitter.

Measurement of liquid level, limit and pressure in cargo oil tanks

Although hydrocarbon products have different properties and low dielectric constants, VEGA radar level gauges can still rely onWide dynamic rangeAccurate measurement directly to the bottom of the tankThe sturdy and durable high-level switch detection is reliable, and can be used as a redundant measurement to add another safety guarantee to the cargo oil tank. Meanwhile, the pressure transmitter utilizes corrosion-resistant materialsCERTEC ® Ceramic measuring componentsIt can accurately monitor the gas phase pressure of cargo oil tanks.

The same ceramic measuring element has also been applied in another measurement field, which isMeasurement of liquid level in ballast tanksThe liquid level gauge here must be submerged underwater for many years,Corrosive saltwater environmentandWater hammer effectStrict requirements have been put forward for instruments.

In addition, ceramic measuring elements have high overload resistance,Capable of withstanding impact pressureEnsure long-term measurement stability. The instrument is also equipped with a display and operation module PLICCCOM, allowing operators to directly read measurement values on site.

Wastewater treatment is an important production process on FPSO ships. All kinds of sewage generated on board need to be treated before being discharged into seawater or reused as reinjection water.

Even when facing large tanks up to 30 meters, this level gauge is effortless, with a customized measuring cable that can reach up to 75 meters in length. In addition, harsh installation conditions are not a problem for this flexible instrument, as its measurement is not affected by narrow openings or internal components of the tank.

For many measurement points on FPSO ships, accurate measurement values are not everything customers need, and simple debugging and maintenance methods are particularly important in offshore operations.

VEGA providesmaintenance-freeEquipped with level and pressure instrumentsBluetooth communicationFunction, allowing users to easily debug. The instrument panel can be operated wirelessly from a distance of up to 50 meters using a mobile phone, tablet, or computer.

In addition, VEGA's radar and pressure instruments can also be installed on ball valves to achieveDismantling with materialsNo need to empty the storage tank.

In the renovation or construction of FPSO projects, whether in oil and gas production, ballast systems, or wastewater treatment, VEGA's level and pressure measurement technology can meet the needs of various measurement applications, helping FPSO floating storage and unloading oil tankers achieve long-term reliable operation.
