TECHNICAL FIELD

The present embodiments generally relate to floating production installations for the storage, storage and offloading of oil (FPSO) and hull structures and discharge systems for a floating installation for drilling, production, storage and shipping (FDPSO).

BACKGROUND

The prior art related to the present invention provides the following reference information regarding the development of marine energy systems, for example, for deep-sea oil and / or gas production. Between subsea wells and a central platform, long field pipelines, power cables and control hoses are often required. Extended lengths are associated with energy losses, pressure drop and production difficulties. Design costs for deepwater applications are high, and costs often increase due to the fact that they are located abroad.

Other difficulties associated with deep-sea offshore operations are due to the movements of the floating installation, which affect personnel and efficiency, especially when they are related to the fluid dynamics in tanks. The main traffic-related problem associated with offshore petrochemical work arises in large horizontal installations, in which the fluid level fluctuates and provides erroneous signals to the fluid level instruments, causing a violation of technology and a general inefficiency of operation.

The main elements that can be modified to improve the motion characteristics of a moored floating installation are the draft, the area of the waterline and the rate of change of its draft, the location of the center of gravity (CG), the metacentric height around which the roll with small amplitude and pitch movement occurs, the frontal area and the form affected by winds, currents and waves, the response of a system of pipes and cables in contact with the seabed acting as mooring elements, and hydrodynamic pa ametry added mass and damping. The latter values can be determined by complex solutions of the equations of potential flows, integrated according to detailed features and protruding parts of floating installations, and then simultaneously solved for potential sources of forces. It is only important to note here that adding features that allow “tuning” the added mass and / or damping for a particular state requires that some features can be modified in combination, or more preferably independently, to provide the desired properties. Optimization can be greatly simplified if the installation has vertical axial symmetry, as in the present invention, which reduces 6 degrees of freedom of movement to 4, (i.e., pendulum motion = roll = pitch, swing = longitudinal = lateral motion = rotational movement and wavelike = vertical movement). It can be further simplified if the hydrodynamic features of the structure can be separated to linearize the process and facilitate the search for the ideal solution.

In the prior art for marine floating structures provide improved hydrodynamic characteristics and the possibility of mooring at increased depths, providing through this platform satellite in deep water, which leads to a shorter field pipeline, cables and umbilicals from the bottom of the earthenware to the platform complex. Previous designs contain a retractable central assembly, which contains features for hydrodynamic improvement and provides for the integrated use of vertical separators in an amount and size that allows for individual continuous monitoring of well production and long retention times.

The main feature of industry installations is a retractable central hub inside the hull, which during operation can be raised or lowered, ensuring passage to shallow water. A retractable central assembly provides pitch damping, a large volumetric space to provide optional ballast, storage, vertical pressure tanks or storage, or a centrally located mine to deploy diving video operations or video operations of a remote-controlled device (ROV) without the need for additional security courts.

Improving the hydrodynamic movement of installations is provided by: the basic configuration of the body; extended fences and edges in the base of the body; (lowered on the site) the central unit with the extension of the retractable central section with the base and installed in the middle of the hydrodynamic fences and ribs, a mass of separators under the deck of the hull, which lowers the center of gravity; and attaching steel chain risers, cables, umbilicals and anchor delays near the center of gravity at the base of the hull. These features improve the stability of the installation and provide increased added mass and damping, which improves the overall response of the system under environmental stress.

Installations of the prior art may have shells that are hexagonal in shape. A floating plant for extraction, storage and shipment may have an octagonal hull. The prior art floating installations for extraction, storage and shipment have a polygonal configuration of the outer side walls with sharp corners to cut the ice strips, resist and break the ice, and move the ice pressure ridges away from the installation. The prior art also provides a drilling and production platform consisting of a semi-submersible platform body having a cylinder shape having a flat bottom and a circular cross section. Previous installations have a circumferential round neck or recess in the lower part of the cylinder, and the design provides a reduction in roll and pitch movement. Since floating installations for extraction, storage, and shipment may be associated with mining risers and usually have to be stable, even in stormy conditions, there remains a need to improve the design of the installation case.

Additionally, there is a need to improve the shipment of a product to a ship or tanker from a floating installation for extraction, storage and shipment, followed by transportation of the product from a floating installation for the extraction, storage and shipment to a surface facility.

As part of an unloading system, an anchor-type mooring buoy (CALM) is usually secured near a floating installation for production, storage and shipment. As an example of a buoy suitable for use with an unloading system, a buoy is attached to the seabed in order to ensure a minimum distance from a nearby floating installation for extraction, storage and shipment. In this example, a pair of cables attach the buoy to the floating plant for mining, storage and shipment, and from the floating plant for mining, storage and shipping to the buoy passes the discharge hose. The tanker is temporarily moored to the buoy, and from the tanker to the buoy they pull the hose for receiving along the hoses connected to the buoy of a product from the floating installation for production, storage and shipment. If bad weather conditions occur during unloading, such as a storm with significant wind speed, problems may arise due to the movement of the tanker caused by wind and current forces affecting the tanker. Therefore, there is also a need to improve the unloading system, usually used when moving a product stored in a floating installation for production, storage and shipment to a tanker.

There is a need for a floating installation that allows the kinetic energy of a floating craft to be absorbed by providing a plurality of dynamic moving tender mechanisms in a tunnel formed in a floating installation.

There is an additional need for a floating installation, which provides wave damping and the destruction of waves inside a tunnel formed in a floating installation.

There is a need for a floating installation, which provides frictional forces in the hull of the floating means in the tunnel.

The present embodiments meet these needs.

The lower conic section 12e may be described here as having the shape of an inverted cone or as having an inverted conical shape, unlike the upper conic section 12c, which may be described here as having a regular conical shape.

In this embodiment, the floating installation 10 for production, storage and shipment is shown floating, so that the surface of the water can cross the upper cylindrical part 12b when it is loaded and / or filled with ballast. In this embodiment, the upper conical section 12c may have a substantially greater vertical height than the lower conical section 12e, and the upper cylindrical part 12b may have a slightly larger vertical height than the lower cylindrical section 12f.

In this embodiment, in order to reduce the heave and otherwise stabilize the floating installation 10 for production, storage and shipment, at least one edge 84 may be attached to the lower and outer part of the hull.

In this embodiment, a low center of gravity 87 is depicted which provides inherent stability to the floating installation 10 for production, storage and shipment.

For mooring a floating installation 10, at least one anchor cable 16a and 16f is shown for the extraction, storage and shipment.

A shaft 92 is shown formed in the center of the housing 9d and extending through the bottom surface 12g.

Figure 9 shows a cross-section of a floating installation for extraction, storage and shipment with a hull 9d.

The housing 9d may have at least one edge. In this embodiment, a plurality of ribs 84a, 84b, 84c and 84d are shown. When using multiple edges 84a, 84b, 84c, and 84d, multiple edges can be separated from each other by a plurality of gaps 86a, 86b, 86c, and 86d. Between the plurality of ribs 84a, 84b, 84c and 84d, a plurality of gaps 86a, 86b, 86c and 86d can be spaced, which can provide a place that holds at least one chain-mounted mining riser, for example, a mining riser and anchor cable outside of the housing 9d without contact with at least one edge 84a, 84b, 84c, and 84d. In embodiments, the ribs may be radial ribs.

In the plurality of gaps 86a, 86b, 86c and 86d, at least one anchor cable 16a, 16b, 16c and 16d may be adopted, respectively. At least one anchor cable attaches a floating rig for drilling, mining, storing and shipping and / or a floating rig 10 for mining, storing and shipping to the seabed. A variety of gaps 86a, 86b, 86c, and 86d can receive chain mining risers that can deliver natural resources, such as crude oil, natural gas and / or leached minerals, from the land below the seabed to the reservoir inside the floating installation 10 for production, storage and shipment.

The shaft 92 is also depicted with a hole 91 to the bottom surface.

Figure 10 shows at least one edge 84a and 84b to reduce heave.

Each section of at least one edge 84a and 84b may have a rectangular triangle shape in a vertical cross section, where a 90 degree angle may be located next to the lowest outer side wall of the bottom cylindrical section 12f of any body shown here as body 9d, so that the lower edge 85 of the triangular shape of at least one rib 84a and 84b is in the same plane with the lower surface 12g of the body 9d.

The triangular hypotenuse 82 extends from the distal end 88 of the lower edge 85 of the triangular form upwards and inwards to attach to the outer side wall of the lower cylindrical section 12f at a point only slightly higher than the lowermost edge of the outer side wall of the lower cylindrical section 12f. Some experiments may be required to determine the optimal effective size of at least one edge 84a and 84b. As one example, the starting point may be the lower edge 85, extending radially outward for a distance that may be about half the vertical height of the lower cylindrical section 12f, and hypotenuse 82 is attached to the lower cylindrical section 12f, for example, about a quarter of the vertical height of the lower cylindrical section 12f from the bottom surface 12g of the housing, or a combination thereof.

The orientation of each edge of a triangular shape can be changed to 45 degrees and fixed to the body and be suitable for use.

After the floating installation for production, storage and shipment can be anchored, and its installation can be completed in some other way, it can be used for drilling exploration or production wells, provided the drilling rig is installed, and it can be used for production and storage stock or products.

At least one ballast tank 96 is depicted for loading and unloading ballast from a floating unit 10 for production, storage and shipment, as well as a mine 92.

Figure 11 provides a perspective detailed image of a floating installation 10 for production, storage and shipment with details of at least one attached rib 84, transitional from one of the above configurations of the hull.

A plurality of gaps 86a and 86b are shown, separating at least one edge 84.

It should be noted that this hull design with a submerged hull section having at least one edge and a heavier or larger lower cylindrical section can create a hull that provides improved hydrodynamic efficiency due to linear and quadratic damping, namely suppression of outgoing waves and friction of viscous origin when this part of the body is immersed.

In an embodiment, the installation may have an ellipsoidal plan view, the dynamic response of the hull may be independent of the direction of the waves (without taking into account any asymmetry of the mooring system, risers and underwater protruding parts), minimizing thereby the wave-induced spreading forces. When the installation has a conical hull, the hull can be structurally efficient, providing a high payload and storage volume per ton of steel compared to traditional marine structures with a ship shape.

In embodiments, the housing may have ellipsoidal walls that may be ellipsoidal in radial cross-section, but this shape can be approximated by using a large number of flat metal plates, rather than plates bent to the desired curvature. The polygonal shape of the body in the plan can be applied according to alternative embodiments.
