There are different types of FPSOs, each with their own unique characteristics and capabilities. Some of the most common types of FPSOs include:
Types of FPSO
Converted FPSO: These are existing tankers that are converted into FPSOs. They are typically smaller than purpose-built FPSOs, and may have limited storage capacity.
Newbuild FPSO: These are purpose-built vessels that are designed specifically for use as FPSOs. They can be customized to meet specific project requirements, and are typically larger than converted FPSOs.
Turret-Moored FPSO: These FPSOs are moored to the seabed using a turret system, which allows the vessel to rotate around a fixed point. This can help to reduce stress on the mooring lines, and improve the vessel’s ability to withstand harsh weather conditions.
Spread-Moored FPSO: These FPSOs are moored to the seabed using a series of anchors and chains. They are typically used in shallow water locations, and may have a lower storage capacity than turret-moored FPSOs.
Floating LNG FPSO: These FPSOs are designed for the production and storage of liquefied natural gas (LNG). They are similar in design to conventional FPSOs, but are optimized for the specific requirements of LNG production.
Hybrid FPSO: These FPSOs combine elements of different types of vessels, such as a tanker and a drilling rig. They are designed to be highly versatile, and can be used for a range of offshore operations.
Each type of FPSO has its own advantages and disadvantages, and the choice of which type to use will depend on a range of factors, including the characteristics of the offshore field, the production requirements, and the environmental conditions in the area.
