Turret mooring system of FPSO. A mooring turret is installed at the centre of the ship, where all anchoring lines terminate and around which the ship is free to. Thirty years ago, SBM Offshore pioneered the turret concept to moor vessel- based FPSOs. Since then we’ve installed nearly 50 turrets around the world. Floating Production Storage and Offloading vessels, or FPSOs, are offshore from the seafloor to the vessel’s turret and then to the FPSO on the water’s surface.

Sometimes it can be found in the middle. After processing, an FPSO stores oil or gas before offloading periodically to shuttle tankers or transmitting processed petroleum via pipelines. The turret sinks beneath the waves and can be reconnected later. This Azurite FDPSO incorporates deepwater drilling equipment that will help to develop the field and can be removed and reused after all the Azurite production cpso have been drilled.

Floating Production Storage and Offloading vessels, or FPSOs, are offshore production facilities that house both processing equipment and storage for produced hydrocarbons. The turretsmooring lines and risers can be designed turre be: How Does Well Control Work?

Turret mooring system of FPSO

Depending on the type of vessel its operations location internal or external turret may be used. Permanently moored, FPSOs are viable development solutions for a number of different offshore field situations.

For more information and data about oil and gas and petrochemical projects go to Project Smart Explorer. Leave a Reply Click here to cancel reply. Usually tied to multiple subsea wells, FPSOs gather hydrocarbons from subsea production wells through a series of in-field pipelines.


Wild Well Control Backed by a heritage of more than 40 years of well control experience, the Wild Well University Well Tureet Training Program delivers action-oriented curricula designed to challenge students in both individual and team performance scenarios.

Gurret basic design of most FPSOs encompasses a ship-shaped vessel, with processing equipment, or topsides, aboard the vessel’s deck and hydrocarbon storage below in the double hull. Moored in place by various mooring systems, FPSOs are effective development solutions for both deepwater and ultra-deepwater fields. More How it Works Articles.

NACE International With programs developed, peer reviewed, and taught by industry experts, NACE provides corrosion control training and certification to help students launch a career, broaden their expertise, and provide greater industry recognition and credibility.

It comprises a steal box located at the bow or stern of the vesselwhich provides a foundation for the bearing and truret.

Turret mooring system of FPSO

Also, FPSOs are an optimal choice for development when there are no existing pipelines or infrastructure to transfer production to shore. For harsher environments like the North Seathe turret is generally located internally. A swivel provides product and utility connections between the tanker facilities and the seabed. An advantage of the internal turret in comparison to the external turret is that mooring forces can be transferred more easily into the hull.

The internal turret is located in the front end of a vessel. Loading oil from the stern of the FPSO to the bow of the shuttle tanker is known as tandem turrer. This provides a more operational uptime and less risk of tanker collision compared with spread-moored FPSO s.


Turre Does Gas Injection Work? Hydrocarbons are then transferred to the vessel’s double-hull for storage. It also up lift the oil and gas and associated water and condensates production risers as well as it supports piping for water or gas injection when used. If fpxo turret is attached to the floating unit, the turret is part of the mooring system and called Turret Mooring system. Crude oil that is stored onboard is frequently transferred to shuttle tankers or ocean barges going ashore, via a loading hose.

Besides this incident, FPSOs have spilled less than approximately barrels of oil combined. Because FPSOs can be disconnected from their moorings, these offshore production vessels are optimal for areas that experience adverse weather conditions, such as cyclones and hurricanes.

About Us About us. The external turret is mostly set-up above the waterline, but sometimes also under.

In relatively calm waters, such as in West Africaturrets can be located externally to the ship structure, hanging off the bow of the FPSO. Being positioned outside of the hull the external turret can bear less risers and production equipment than internal turret.
