This application claims the priority of Norwegian Patent Application No. 20161699, filed on October 27, 2016, the contents of which are incorporated herein by reference for all purposes.

Significant problems exist for floating offshore structures located in waters affected by extreme sea conditions, such as by storm surges. It is well known that storm surges occur mainly in shallow water near land, for example, related to tropical cyclones, where the water level near the coast may temporarily increase by as much as 8 to 9 meters. This will impose a huge upward force on the Gravity Based Structure (GBS), which has a liquid reservoir with a large waterline surface area at sea level and is located near the coast. The additional fixed ballast volume used to offset this temporary uplift force will require a significant increase in the volume and weight of the gravity structure to ensure that the bottom pressure is always positive and that the gravity structure floats in, dives and Additional buoyancy during installation on the sea floor. This increase in volume will again increase the lifting force, which in turn requires additional ballast volume for both seawater ballast and fixed ballast. This indicates a negative design effect spiral, which will make gravity structural solutions very expensive.

It is also known that for use in soft and loose seabed soils, such as can be found in river deltas, gravity structural solutions may not be feasible or would be very expensive in the best case. For this reason, gravity structures can be equipped with a suction skirt, but the dimensions and vertical height of such a skirt solution can represent an overly expensive foundation solution, which has so far enabled storage Floating storage body becomes the only viable solution in areas with such soil conditions.

To reduce the problems associated with the dynamics of the buoy during loading operations, it has been proposed to install large rectangular or square steel or concrete structures on the sea floor for use as artificial seaports, where continuous steel or concrete walls are expected Protects against incoming waves. The typical depth of the proposed waters is 8 to 30 meters. This type of large building structure is expected to be constructed away from the residential area and at the same time liquefied natural gas (LNG) vessels are used as breakwaters during loading and unloading operations.

Wave problems can be reduced by moving ships to the leeward side of the harbour building structure, but calculations and watershed experiments have shown that if people want to obtain significant occlusion effects when waves hit from a particularly unfavorable angle during a period of time The harbour building structure that forms a continuous barrier must be constructed to be very large. This is due to the well-known effect that the waves will be diffracted around both sides of this building structure, and the focal point where the diffracted waves meet will appear some distance behind the leeward side. At this focal point, the height of the waves may actually be higher than the coming waves.

Large harbour building structures placed on the bottom of the ocean that are intended to act as wave shelters will therefore be very expensive. Different forms have been proposed for this type of LNG harbour site constructed of concrete and used to shield ships from waves. One proposed shape is, for example, a building structure constructed as a U-shape and an LNG ship is loaded / unloaded inside the building structure. This will significantly reduce power, but the harbour location will be even more expensive than a rectangular-shaped harbour location.

GB 1369915 describes a harbour site comprising several units that are floating or sinking and are otherwise constructed to be placed on the sea floor. Each unit includes a load-bearing base structure and removable wave-breaking elements that can be moved when needed.

US 3,958,426 describes a harbour site comprising several units which are placed separately on the sea floor so as to form at least one straight mooring position. The unit is provided with a bumper and a wave damping device.

WO 2006/041312 discloses a seaport facility for storing, loading, and unloading hydrocarbons such as liquefied natural gas at sea. The entire contents of this patent are incorporated herein by reference. The harbour consists of three units made of steel or concrete placed on the sea floor. The units are placed in rows in a lateral relationship. The harbour is configured to dampen waves and the ship is expected to be on the leeward mooring side.

WO 2013/002648 discloses a harbour facility for storing, loading and unloading hydrocarbon products at sea, which includes several units placed on the seabed with each other to form the harbour facility. The units are independently placed at a given distance in a lateral direction and have a front surface, the ship is expected to moor along the front surface, the unit forms a passage for some parts of the wave and is structured to counter incoming waves Part of it is damped while allowing waves and other parts of the current to pass through the harbor facility.

US 2005/139595 describes a facility for storing and loading liquefied natural gas, which consists of a sea floor structure resting on the sea floor, the sea floor structure having a base slat resting on the sea floor, and three upwardly extending walls. The seabed structure has an opening, so that the floating module can be transported to a position inside the seabed structure and pressurized to rest on a base slat.

FR 2894646 describes a gravity-type structure that is placed on the sea floor due to its own weight and is provided with a skirt that protrudes downward and opens, said skirt being pressed into the sea floor. The gravity structure has a U-shaped form, has a vertical wall extending upward from an underwater bottom slat, and is provided with a buoyancy chamber serving as a weight block to provide a required weight. An embodiment of the gravity structure may also be provided with a pile extending downward through the vertical wall and into the supporting soil, said pile terminating at the top of the wall above sea level.

However, these harbor facilities for storage can be large, complex and expensive. Building these harbour facilities can take a long time and has limited variations with respect to mobility and other applications. Due to the dependence on the deep skirt to achieve the foundation, problems can also be encountered during installation, especially in shallow waters with muddy or soft seabeds. In addition, the density, composition, compactness, and morphology of seabed soils can vary significantly from one seabed location to another. For example, the soil in the estuary will often be dominated by soft argillaceous soil with a yogurt texture, while other seabed areas may be affected by or overlap with hard sandstone, limestone, or ancient volcanic rocks. This will have a direct impact on the load-bearing capacity of the seabed soil and therefore the possibility of finding a predictable and reliable foundation solution for the seabed structure that will rest on the seabed.

Therefore, there is a need for a cost-effective, versatile, and flexible harbor facility system that can be installed in shallow water and suitable for installation in areas of the sea floor with poor load carrying capacity. In addition, there is a need for an offshore facility that can be standardized as much as possible for manufacturing and cost reasons and can be easily deployed offshore or near coastal locations with any type of seabed soil.

There is also a need for a method for ensuring that such harbour facilities are properly and adequately piled, thereby avoiding relative movement between the facility and the sea floor during the piling operation.

The principle used according to the present invention is to use a pile-type base structure in which the weight of a floatable body that is docked in and supported by the base structure is by a structure that terminates above the sea level, Loaded and / or fastened piles pass almost directly down into the sea floor. In addition, another principle used is the use of gravity and / or ballast to securely anchor or anchor the buoy to the docking bay. The buoyant body or the floating body can be almost completely subjected to buoyancy by leaving a gap filled with water at least between the bottom of the floating body and the corresponding upper surface of the base structure. If necessary, the floating body can be anchored to the mooring area (or base structure) in combination with the mooring force. In this regard, the base structure may rest on the sea floor with at least a portion of its foot print, or the base structure may be positioned some distance above the sea floor soil, ie, without actually touching the sea floor soil. In either case, All loads, weights and forces are borne by the piles and transferred to the sea floor by the piles.

The object of the present invention is to provide a foundation and support system and a mounting method for a base structure that directly transfers loads, forces and bending moments from a floating structure (or floating body) that is parked to the seabed soil In the deeper layer without causing the support or the berth to fail or become unstable due to environmental forces or other related forces acting on the base structure.

Another object of the present invention is to provide a shallow water seabed transfer station that is flexible, cost-effective and easy to establish in most types of seabed soil conditions.

Another object of the present invention is to provide a near-shore storage system, which can also be located in extremely soft and muddy soils that can be found in river deltas and unconsolidated seabed areas when needed, and in these areas, Gravity-type structures cannot be installed or the installation of gravity-type structures will be too expensive, and if not done with too complicated work, the floating body may be removed again after the task is completed. .

An additional object of the present invention is that it can be endowed with a structural ability to withstand large uplift buoyancy during an extreme storm surge without its load bearing structure being subject to any significant volume changes.

In addition, the object of the present invention is to directly guarantee the safe transmission and / or distribution of large vertical loads and forces from the floating body to the base structure and the safe transmission and / or distribution from the base structure to the pile and the safe transmission and / or distribution from the pile to In the sea floor, the large vertical load and force are caused by the storage of a large volume of liquid in the floating body and / or the load and force caused by sea conditions and weather.

In addition, the object of the present invention is to provide a seabed transfer station including a seabed substructure and a modular buoyant body, the seabed base structure and the modular buoyant body are specially designed as Adapt to each other and simplify the berthing and berthing of buoyant bodies in a time- and cost-effective manner.

In addition, the object of the present invention is to achieve quick, safe and releasable installation and parking of the floating body using topside equipment.

Another object of the present invention is to avoid local failure of one or more piles due to local excessive load impact caused by the assembled base structure and floating structure, the applied loads and forces are balanced out and also distributed to adjacent piles.

Still another object of the present invention is to provide a parking system based on a pile system, in which an applied load and force caused by an environmental force acting on an assembled structure or a load and force imposed on a base structure by a floating structure are provided.

According to an embodiment, a method for mooring a floating body in a harbor facility is provided. The method may include: a pile-type base structure provided with two side walls protruding upward through the sea level, the two side walls terminating above the sea level; and a laterally configured bottom structure rigidly interconnecting the side walls . The two side walls may be two opposite side walls facing each other.

In other words, the base structure may be configured to be supported by the sea floor with several piles. For example, the pile may terminate at the top surface of the side wall above sea level.

Further, the floating body is configured to be rigidly but releasably supported by at least some portions of the side wall. The floating body is floated to a position between the side walls, and at the same time that the floating body is almost completely subjected to buoyancy by leaving a gap filled with water at least between the bottom of the floating body and the corresponding upper surface of the base structure. The floating body is rigidly fixed to the vertical side wall of the base structure, thereby preventing relative vertical movement between the floating body and the base structure.

As an option, the floating body can be rigidly fixed to the base structure by disposing several tensioning devices between the floating body and the upper part (or upper or top part or top) of the side wall, said tensioning The device is rigidly fixed at one end to a strong point on the floating body and the opposite end is rigidly fixed to the upper end of the side wall.

For example, the tension rod applies additional force, which is combined with gravity and ballast to increase the fixing capacity to bear the variation of the vertical load.

According to the invention, the surface on the floating body can be placed on the surface of the side wall on the upper end surface (or the top surface) in close association with the upper end of the pile, and the pile supports the base structure on the sea floor and vertically downward Extends through the side walls and into the sea floor.

Above (or above) the top (or top surface or portion) of the sidewall. The top surface of the side wall may be provided with a correspondingly configured complementary strong support point configured to carry at least a part of the weight of the floating body.

The solid support points on the side walls may preferably be formed by the top ends of the piles serving as the foundation structure, so that the weight can be transferred from the supported floating body directly to the sea floor through the piles. The top end of a pile may refer to the end region (or end portion) of the pile, for example, the pile may terminate at the top surface of the side wall in the end region (or end portion). It should be understood and understood that the pile need not necessarily terminate at the top surface of the side wall. In other words, the pile can terminate at any position along the pile sleeve.

A part of the weight of the buoyant body can be preferably compensated by buoyancy, and in the case of an increase in seawater level, ballast water can be added and / or the increase of the lifting force is borne by the tensioning device.

A damping device may be provided on the top surface of the side wall, the damping device is configured to act as a shock absorber during mating of the floating body to the base structure, thereby ensuring that the load and force are controlled The ground is transferred to the base structure and it may also be possible to ensure that the loads and forces are distributed in a way that prevents part of the base structure and / or adjacent piles from being overloaded.

According to another embodiment of the present invention, a jack can be configured between the corresponding solid support point on the top of the side wall and the corresponding solid support point on the floating body, so that the floating body can be lifted to Optimum weight and / or buoyancy balance is achieved between the two structures and between the mated structure on one side and the pile-seabed interface on the other.

The tensioning device may be rigidly fixed distally to a solid support point on the floating body and the opposite end rigidly fixed to a solid support point at the upper end of the side wall. More specifically, the tension in the tensioning device can be adjusted to ensure sufficient support and fixing force, one end of each said tensioning device is fixed to a solid support point on the top surface of the side wall and the other end is fixed to the floating body .

The present invention also relates to a harbor facility for mooring a buoy as described above, wherein the vertical side walls are configured to carry the weight of the buoy in a rigid but releasable fixed state, and because at least the bottom of the buoy and the There is a gap filled with water between the corresponding upper surfaces of the base structure, which still makes the floating structure more or less buoyant, and by means of several tensioning devices arranged between the floating body and the bottom of the side wall, it will prevent Relative vertical movement occurs between the floating body and the base structure.

According to an embodiment, the solid support points on the floating body may be disposed on a vertical surface protruding outward from the side of the floating body, and the solid support points on the floating body may be disposed / located on the side wall of the base structure. Above the top, the top surface of the side wall is provided with a correspondingly configured complementary strong support point configured to carry at least a part of the weight of the floating body.

The solid support points on the side walls can be formed by the tops of the piles that serve as the foundation for the base structure, thereby enabling weight to be transferred from the supported floating body directly to the sea floor through the piles.

A jack can be arranged between the solid support points on the top of the side wall and below the bottom of the solid support points protruding laterally outward from the floating body to adjust the tension in the tensioning device.

In addition, the tensioning device may be provided with a device for adjusting tension to ensure sufficient support and fixing force.

The solid support points on the top surface of the side wall correspond to or are closely associated with the upper ends of the piles supporting the base structure and extending through the side wall and into the sea floor.

The wall structure may form an integral part of the base structure, thereby forming a seabed base structure unit, and the wall structure may be provided with a ballast member. At least some portions of the wall structure extend above the water surface.

According to the present invention, there is provided a shallow water base structure, for example for storing and loading or unloading hydrocarbons (such as liquefied natural gas, oil or gas), comprising a floating seabed base structure intended to be supported by a seabed, said seabed The base structure preferably includes a base structure provided with a wall structure extending upward, the wall structure is arranged along at least a part of the periphery of the base structure, and the base structure is preferably also provided with an opening in the wall structure. So that the buoyant body can be parked, moored and supported by the basic structure of the sea floor. The base structure is provided with a solid support point configured to receive a corresponding solid support point on the buoyant body, and preferably also provided with a pre-installed vertical pile end to connect the base structure to a permanent pile driving operation to the sea floor. At least a separate solid support point for the base structure is temporarily supported during this period.

A solid support point can be placed on top of the side wall above sea level.

The solid support points can be located at different locations along the outside of the side wall. In still other embodiments, the solid support points can be configured at any position on the base structure, so that the solid support points are configured to receive the corresponding solid support points on the floating body, and are preferably configured to be aligned with the pre-installed vertical piles. The ends are connected to at least temporarily support the base structure during the piling operation of permanently piling the base structure to the sea floor.

It should be understood that the solid support points on the floating body may be configured at a position that enables deployment / location above the solid support points of the base structure.

According to an embodiment, the wall structure may form an integral part of the base structure, and the solid support point forms an integral part of the wall structure.

Alternatively, the solid support points may be positioned below the sea level on the side walls or the bottom surface of the base structure. Where a solid support point is positioned on the bottom surface, the pile may form a permanent part of the pile system.

The base structure is supported to the seabed with piles using several permanent piles driven into the seabed, and the tops of the piles are rigidly fixed to the base structure along the height of the side walls.

The seabed base structure includes a base structure provided with a buoyancy device and an upwardly extending wall structure also provided with a buoyancy device. The wall structure is configured along at least a portion of the periphery of the base structure and includes at least one opening in the wall structure for introducing a floatable storage module. The buoyant module is removably disposed on the top of the base structure within the wall structure, thereby collectively forming an offshore unit supported by the sea floor at least by piles.

According to a preferred embodiment of the present invention, the wall structure of the base forms an integral part of the base structure, thereby forming a seawater-based structural unit. In addition, a cantilever, beam or slab placed at the top of the side wall forms an integral part of the wall structure and is designed and sized to withstand all temporary loads that occur during the piling process, Forces and moments. For this purpose, cantilever beams, beams or slats may be provided with strong support points to work with piles installed for temporary use.

It should be understood that the floating body base may be provided with a ballast tank and a pumping system to use water to adjust the weight and buoyancy as well as the vertical forces and loads acting on the system during operation.

The wall structure of the seabed base structure terminates above sea level. As shown in the diagram, some of the advantages of having a portion of the seabed base structure above the water are: a) The water plane helps reduce the instability of stability during the installation of the seabed base structure Certainty. b) The part of the sea floor structure will help and simplify the floating access and installation of the storage module. c) The piling machine can be placed on the base structure above the horizontal plane, which reduces the cost and time, and then becomes unaffected by sea conditions during the piling process. d) The fact that the base structure of the sea floor is above the horizontal plane will indicate an increased resistance to collisions with ships. e) In some cases, some equipment (for example, a cargo loading arm) may be installed on the seabed base structure and therefore at a distance from the buoy.

By providing outwardly protruding beams or slats for the dock area, the ship can be parked at a distance from the vertical wall, thereby enhancing the ability to transfer and moor ships along the dock area.

In addition, this feature of the present invention is also very useful when installed in shallow areas affected by cyclones and storm surges, where water levels can rise up to 8 above normal sea level in extreme conditions over 100 years Meters to 9 meters. In this case, the tension rod arranged between the base structure and the floating body can bear a large part (if not all) of the lifting buoyancy, and the other parts of these extreme temporary lifting forces can be obtained by the storage module Add effective water ballast to offset.

The seabed unit of the seabed transfer station can be designed to be extremely heavy due to the large weight of liquid stored in the storage module (usually up to but not limited to 150,000 metric tons (tonne) load, corresponding to the capacity of large tankers). Large vertical loads are transmitted to the sea floor without any movement at the sea floor transfer station. Part of this capacity can be obtained by increasing the height of the storage module while maintaining the horizontal footprint of the seabed transfer station.

The following description of the exemplary embodiments is made with reference to the drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Instead, the scope of the invention is only defined by the scope of the accompanying patent application. For the sake of brevity, the following embodiments are related to a method for generally mounting the base structure on the sea floor and preferably (but not necessarily) on the inclined sea floor and / or the sea floor with low bearing capacity. Exposition.

Throughout this specification, "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Therefore, the phrases “in one embodiment” or “in an embodiment” appearing in various places throughout this specification do not necessarily refer to the same embodiment.

The key point of the present invention is to achieve fast and safe installation of the storage module by using deck equipment, in which the foundation structure is stably and rigidly supported during the pile driving operation of the permanent pile. With a pre-installed foundation (which is stabilized by at least a pile and aligned in advance to the sea floor), the installation of the storage module can be completed within a few hours.

In addition, the invention provides the possibility of establishing seabed transfer stations on different soil conditions. The density, composition, compactness, and morphology of seabed soils can vary significantly from one seabed location to another. This will have a direct impact on the load bearing capacity of the seabed soil and therefore the possibility of finding a predictable and reliable foundational solution for the seabed structure to be supported by the seabed. According to one embodiment, the base foundation may be in the form of a semi-submersible floating body supported by a pile to the sea floor. In this case, the foundation base structure can be pressurized as a semi-submersible structure and supported by piles to the sea floor through the base structure and possibly through (but not necessarily) the sea floor base structure. In these cases, it is important to be able to efficiently transfer vertical structural forces, which has the following advantages: the main structural beam and the storage module of the base structure have a mirror structure interface. This means that the vertical force from the bulkhead of the storage module is preferably transmitted directly into the main structural beam of the base structure and into the pile structure and to the sea floor. Calculations have shown that the pile-type seabed base structure must be able to tolerate and tolerate a weight of 100,000 to 120,000 tons.

FIG. 1 schematically shows the first stage of the installation procedure, in which two rows of spaced-apart aligned piles 14 are arranged, and the last pile in the row 14 ′ is in the process of being forced into the sea floor 30 by a pile barge 15 The piling barge 15 includes a crane 16 and a pile driving tool 17 suspended from the crane 16. During this stage, the flat-deck barge 15 can be moored by a conventional seabed anchor (not shown in the figure) and a mooring line 18 (two shown in the figure). As shown, the pile 14 terminates at a predefined height above sea level 29.

FIG. 2 schematically illustrates that the base structure 10 is being towed into position between two rows of aligned piles 14 by a towing vessel 19 and a pair of towing ropes 20. The base structure 10 includes two vertically-arranged sidewalls 22 that are rigidly fixed to a bottom structure disposed in the middle, thereby forming a mooring structure having a U shape, which is configured as For parking or mooring the floating body 11. At the top of the vertically extending side walls 22, each side wall 22 is provided with cantilever beams 21, 21 'protruding outward, the cantilever beams 21, 21' extending outward on each side of the base structure 10 from the top of the base structure 10 Extending laterally outwardly along two parallel side walls 22, each cantilever 21, 21 'is configured to rest on top of a corresponding row of piles 14. For this purpose, the cantilever beams 21, 21 'are provided with strong support points 24 (not shown in FIG. 2). The size and structure of the strong support points 24 are suitable for temporarily transferring the weight of the base structure 10 and may also carry at least the base The temporarily occurring loads, forces and bending moments introduced during the installation phase of the structure 10 until the foundation structure is safely supported by the piles to the sea floor 30.

The base structure 10 is provided with a system (not shown) for ballasting, and is preferably made of steel, however, other materials such as concrete may be used. It should be understood that the base structure 10 according to the present invention may also be provided with auxiliary devices and systems, such as a loading system, a crane, a winch, etc., which are permanently or temporarily disposed on the top of the base structure 10. When the buoy or buoyancy module 11 arrives at the location, it is transferred in a floating state between the two side walls 22 extending upward. During this mating operation, the floating body 11 is adjusted through an opening 23 located at one end of the base structure 10 and between two parallel and upwardly extending side wall structures 22. The floating body 11 is guided in such a manner that the solid support points on the floating body 11 are vertically aligned with corresponding solid support points disposed on the top surface of the side wall 22. Such a strong support point located on the top surfaces of the two vertical walls 22 corresponds to the top end of the pile 25 substantially terminating at the top surfaces of the vertical walls 22. Next, the floating module is pressurized so that it is stably rested on the upper end of the vertical wall 22 of the base structure 10. At locations where seawater levels have changed significantly (or at challenging locations), compensation may need to be made (for example, by using ballast water or effective ballast). However, at locations where changes in seawater level are not significant, compensation may not be required by, for example, using ballast water, and the floating module can still stably rest on the upper end of the vertical wall 22 of the base structure 10. In either case, it should be understood that there should be a gap between the upper surface of the interconnect structure (the base structure) and the bottom surface of the floating body 11. In other words, the upper surface of the interconnect structure and the bottom surface of the floating body 11 are not in direct contact with each other.

FIG. 3 schematically and perspectively illustrates an embodiment of a base structure 10 that is mounted on top of and supported by a group of intermediate piles 14. As shown, the temporary pile 14 is aligned with a strong support point 24 protruding laterally outward from the upper and outer portions of the side wall 22. The base structure 10 includes two vertically arranged walls 22 interconnected at the lower end by three horizontally arranged box beams 25 which are rigidly fixed to the side wall 22. In addition, as shown, the base structure 10 is expected to be supported by the piles to the sea floor 30 by two rows of piles 13. For this purpose, the vertical wall 22 is provided with two rows of casings 27 which serve as guide members so that the casing 27 in the vertical wall 22 can be passed above the sea level 29 And piling is performed into the seabed soil. According to the installation phase shown in Figure 3, the permanent piling process has not yet started. As further shown, if necessary, the box beam 26 may also be provided with a sleeve 27 to achieve proper fixing of the base structure to the sea floor 30.

Fig. 4 shows schematically and three-dimensionally the transfer stage of the piling operation, in which the working barge 15 'is moored beside the outside of the vertical wall structure 22. On the deck of the flat deck barge 15 ', pile materials 31 to be used for piling are stored. In addition, the hydraulic hammer 32 is indicated. Across the two vertical side walls 22, at one end of the base structure, a temporarily installed platform 33 is arranged to store further pile materials 31 'to be used for piling.

FIG. 5 schematically and perspectively shows a view of the base structure during the transfer phase of the piling operation of the permanent pile 25 on the elevated platform 34. Each end of the elevated platform 34 runs on rails (not shown) arranged along each of the side walls 22, thereby enabling the elevated platform to operate along the length of the base structure 10. A crawler crane 35 is disposed on the elevated platform 34. The crawler crane 35 is configured to move back and forth on the elevated platform 34 to collect the pile 25 from the pile raw materials 31, 31 'and pass the pile 25 through the hydraulic hammer 32. Installed through sleeve 27. As shown in the figure, the hydraulic hammer 32 and the permanent pile 25 are suspended from the hooks of the crawler crane 35, and the pile 25 is in the process of being piled through the corresponding sleeve 27 penetrating the side wall 22.

In addition, rail-type welding stations (not shown) can also be used for welding work related to the fixation of the complete pile structure, said rail-type welding stations being located on each of the top sides of the side walls 22 On a pair of rails (not shown).

The base structure 10 may also be provided with an anti-collision system (not shown in the figure) and a mooring and winch system (not shown in the figure), so that the ship is moored along at least one side of the base structure 22.
