This application claims the priority right of the Norwegian patent application No. 20161699 filed on October 27, 2016, and the content of the Norwegian patent application is fully incorporated herein for reference for all purposes.

There are major problems for floating offshore structures located in waters affected by extreme sea conditions, for example, due to storm surges. It is well known that storm surges mainly appear in shallow water near land, for example, related to tropical cyclones, where the water level near the coast may temporarily increase as much as 8 to 9 meters. This will be an important part of the gravity structure (Gravity Based Structure (GBS) imposes a huge lifting force, the gravity structure has a liquid reservoir with a large waterplane area at sea level and is located near the coast. The additional fixed ballast volume used to offset this temporary upward force will require a significant increase in the volume and weight of the gravity structure to always ensure that the bottom pressure is positive and to ensure that the gravity structure floats in, enters, and dives. There is additional buoyancy during installation on the seabed. This increase in volume will once again increase the lifting force, which in turn requires additional ballast volume for both seawater ballast and fixed ballast. This represents a negative design effect spiral, which will make the gravity structural solution very expensive.

It is also known that for use in soft and loose seabed soils (such as those found in river deltas), gravity-based structural solutions may not be feasible or in the best case will be very expensive. For this reason, the gravity structure can be equipped with a suction skirt, but the mere size and vertical height of this skirt solution can represent an overly expensive basic solution, which has made storage so far Floating storage body has become the only feasible solution in areas with such soil conditions.

In order to reduce the problems associated with the dynamics of the floating body during the loading operation, it has been proposed to install large rectangular or square steel or concrete structures on the seabed for use as an artificial harbour, where continuous steel or concrete walls are expected Form protection against incoming waves. The typical depth of the proposed waters is 8 to 30 meters. This type of large-scale building structure is expected to be built away from residential areas and is also used as a defense for liquefied natural gas (LNG) ships during loading and unloading operations. Jetty.

The wave problem can be reduced by moving the ship to the leeward side of the harbour structure, but calculations and watershed experiments have shown that if people want to obtain a significant shielding effect when the waves arrive from a particularly unfavorable angle during a period of time , The harbour building structure that forms a continuous barrier must be constructed very large. This is due to the well-known effect that the waves will be diffracted around the two sides of the structure, and the focal point where the diffracted waves meet will appear at a certain distance behind the leeward side. At this focal point, the height of the wave may actually be higher than the incoming wave.

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

GB 1369915 describes a harbour site including several units that are floating or sinking and are additionally constructed to be placed on the seabed. Each unit includes a load-bearing base structure and a movable wave breaking element that can be moved when needed.

US 3,958,426 describes a harbour site comprising several units which are placed separately on the seabed so as to form at least one straight berthing position. The unit is provided with an anti-collision device 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 content of this patent is incorporated herein for reference. The harbor consists of three units constructed of steel or concrete placed on the seabed. The cells are placed in a row in a lateral relationship. The harbour is constructed to dampen waves and the ship is expected to be on the leeward side of the mooring.

WO 2013/002648 discloses a harbor facility for storing, loading and unloading hydrocarbon products at sea, which includes several units placed on the seabed to form a harbor facility. The units are placed independently at a given distance in the lateral direction and have a front surface along which the ship is expected to moor. The units form passages for certain parts of the waves and are configured to pair the incoming waves Part of it is damped while allowing other parts of waves and currents to pass through the harbor facilities.

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

FR 2894646 describes a gravity structure that rests on the seabed due to its own weight and is provided with a downwardly protruding and open skirt, which is pressed down into the seabed. The gravity structure has a U-shaped form with a vertical wall extending upward from the underwater bottom slat, and is provided with a buoyancy chamber used as a weight to provide the required weight. An embodiment of the gravity structure can also be provided with a vertical wall extending downward and into Supports piles in the soil that terminate at the top of the wall above sea level.

However, these harbor facilities for storage can be large, complex, and expensive. It will take a long time to construct these seaport facilities, and they have limited variations in terms of mobility applications and other applications. Due to the reliance on deep skirts to achieve the foundation, it can also suffer problems during installation, especially in shallow waters with muddy or soft seabeds. In addition, the density, composition, compactness, and morphology of seabed soil can be significantly different from one seabed location to another. For example, the soil in the estuary will often be dominated by soft muddy soil with a yogurt texture, while other seabed areas can 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 on 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, multi-functional and flexible harbour facility system that can be installed in shallow water and is suitable for installation in areas where the seabed has poor load carrying capacity. In addition, there is a need for an offshore facility that can be standardized as much as possible for production and cost reasons and can be easily deployed in offshore or near coastal locations with any type of seabed soil.

People also need a method to ensure that such harbor facilities are properly and adequately piled, so as to avoid relative movement between the facilities and the seabed during the piling operation.

The principle used in accordance with the present invention is to use a pile-type base structure, in which the weight of the floatable body that is moored into the base structure and supported by the base structure is determined by the structure that terminates above the sea level and above the sea level. The loaded and/or fastened piles are almost directly passed down to the seabed. In addition, another principle used is to use gravity and/or ballast to safely moor or anchor the floating body to a docking bay. The floating 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 moored to the mooring area (or base structure) in combination with the mooring force. In this regard, the base structure may rest on the seabed with at least part of its foot print, or the base structure may be positioned at a certain distance above the seabed soil, that is, not actually contacting the seabed soil, in either case, All loads, weights and forces are borne by the piles and transmitted to the seabed by the piles.

The objective of the present invention is to provide a foundation and support system and an installation method for a base structure that directly transfers the load, force and bending moment from the floating structure (or floating body) berthed to the seabed soil In the deeper layer, the support or the parking foundation will not fail or become unstable due to environmental forces or other related forces acting on the base structure.

Another objective of the present invention is to provide a multipurpose shallow water seabed terminal with berthed floating storage bodies and a method for establishing a fixed state between the floating body and the base structure .

Another object of the present invention is to provide a seabed transfer station, which is designed to transfer the large weight of liquid stored in the berthed body (ie, the berthed floatable body) and/or act on the seabed to transfer Significantly large vertical loads caused by the force and load on the station are transmitted to the seabed soil, and no relative movement between the floating body and the supporting structure and between the seabed and the transfer station is not allowed .

Another object of the present invention is to provide a shallow seabed transfer station that is flexible in use, 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 loose seabed areas when needed, and in these areas, It is impossible to install the gravity structure or the installation of the gravity structure will be too expensive, and if too complicated work is not performed, the floating body may be removed again after the task is completed.

The additional objective of the present invention is that it can be endowed with the structural ability to withstand large upward buoyancy during extreme storm surges without any significant volume change of its load bearing structure.

In addition, the object of the present invention is to directly ensure the safe transfer and/or distribution of large vertical loads and forces from the floating body to the base structure and from the base structure to the piles and from the piles to the piles. In the seabed, the large vertical load and force are generated by storing a large volume of liquid in the floating body and/or due to the load and force generated by sea conditions and weather.

In addition, the object of the present invention is to provide a seabed base structure (seabed substructure) and modular floatable seabed transfer station, the seabed base structure and the modular floatable body are specially designed to adapt to each other and will be floatable in a time and cost-effective manner The parking and parking of the body is simplified.

In addition, the objective of the present invention is to achieve fast, safe and releasable installation and parking of floating bodies using topside equipment.

Another objective 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 load and force are balanced and distributed to adjacent piles.

Another object of the present invention is to provide a mooring system based on a pile material system, in which the load and force caused by the environmental force acting on the assembled structure or the load and force imposed on the base structure by the floating structure The interfaces between the floating structure and the base structure and between the base structure and the pile system are distributed in a controlled manner, thereby avoiding excessive stress and strain in the corresponding interface and avoiding the interface between the pile and the surrounding seabed soil A ground fault has occurred.

Another object of the present invention is to provide a load in which the position of the floating structure relative to the base structure can be vertically aligned and/or the vertical position of the floating structure can be adjusted locally to ensure that the acting load and force are balanced by the system and/or Solutions for force distribution.

Another object of the present invention is to provide a load and force transmission system in which a balanced load and force distribution is established to ensure that the load and force are transmitted to the pile through the base structure in a manner that avoids excessive local stress and strain overload.

Another object of the present invention is to provide a seabed transfer station or seaport or harbour facility with a ship shelter which can advantageously be more cost-effective than using relatively expensive wave breaking structures.

The object of the present invention is achieved by a seabed transfer station and a method for establishing such a seabed transfer station as further defined in the independent claim. The embodiments, alternatives, and variants of the present invention are defined by the attached claims.

According to an embodiment, a method for mooring a floating body in a harbor facility is provided. The harbor facility 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 arranged bottom structure that rigidly interconnects the side walls even. The two side walls may be two opposite side walls facing each other.

In other words, the base structure can be configured to be supported by the seabed by several piles. For example, the pile may terminate at the top surface of the sidewall above sea level. In the context of various embodiments, a floating body may refer to a floating structure or floater or floating module.

The top surface of the bottom structure is configured at a depth that enables the floating body to float into between the two side walls. Furthermore, the floating body is configured to be rigidly but releasably supported by at least some parts of the side walls. The floating body is floated to the position between the side walls, and the floating body is almost completely exposed 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 Fix the floating body rigidly to the vertical side wall of the base structure to prevent the floating body and the base structure Relative vertical movement occurs between.

As an option, the floating body can be rigidly fixed to the base structure by arranging several tensioning devices between the floating body and the upper part (or upper end or top part or top end) of the side wall. 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 exerts an additional force, which is combined with gravity and ballast to increase the fixing capacity to bear the vertical load variation.

According to the present invention, the surface on the floating body can be placed on the surface of the side wall on the upper end surface (or top surface) in close association with the upper end of the pile, which supports the base structure on the seabed and vertically downwards Extend through the side wall and into the seabed.

The floating body can be provided with a solid support point on a part protruding outward from the side of the floating body, and when the floating body can float into between the two side walls, the solid support point of the floating body can be positioned on the base structure Above (or above) the top (or top surface or top portion) of the side wall. The top surface of the side wall may be provided with a correspondingly configured complementary solid support point configured to carry at least a part of the weight of the floating body.

The solid support point on the side wall can preferably be formed by the top of the pile that serves as the foundation for the base structure, so that the weight can be transferred from the supported floating body directly to the seabed through the pile. The top of the pile can refer to the end area (or end part) of the pile, for example, the pile may It terminates 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 end at any position along the pile sleeve.

A part of the weight of the floating body can be better compensated by buoyancy, and when the seawater level increases, ballast water can be added and/or the increase in the lifting force can be borne by the tensioning device.

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

According to another embodiment of the present invention, jacks can be arranged between the corresponding solid support points on the top of the side walls and the corresponding solid support points on the floating body, so that the floating body can be lifted to The best 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 side.

The tensioning device may be rigidly fixed at the distal end to a strong support point on the floating body and the opposite end is rigidly fixed to a strong 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 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 seaport for berthing floating bodies as described above A facility in which the vertical side walls are configured to carry the weight of the floating body through a rigid but releasable fixed state, and at least there is a gap filled with water between the bottom of the floating body and the corresponding upper surface of the base structure. The floating structure can be more or less (or at least partly) affected by buoyancy, and with several tensioning devices arranged between the floating body and the bottom of the side wall, relative vertical movement between the floating body and the base structure will be prevented .

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

The solid support point on the side wall can be formed by the top of the pile that serves as the foundation for the base structure, so that the weight can be transferred from the supported floating body directly to the seabed through the pile.

Jacking devices can be arranged between the solid support points on the top of the side walls 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 can be provided with a device for adjusting tension to ensure sufficient support and fixing force.

The strong support point on the top surface of the side wall corresponds to or is closely associated with the upper end of the pile that supports the base structure and extends through the side wall and into the seabed.

The wall structure can form an integral part of the base structure and then form the seabed base layer The structural unit, and the wall structure may be provided with a pressurized load member. At least some parts of the wall structure extend above the water surface.

According to the present invention, there is provided a shallow-water base structure for storing and loading or unloading hydrocarbons (such as liquefied natural gas, oil or gas), which includes a floatable seabed base structure expected to be supported by the seabed. The base structure preferably includes a base structure provided with an upwardly extending wall structure, the wall structure is arranged along at least a part of the periphery of the base structure, and the base structure preferably also has an opening in the wall structure, So that the floatable body can be parked, moored and supported by the base structure of the seabed. The base structure is provided with a solid support point configured to receive a corresponding solid support point on the floating body, and is preferably also provided for connecting with the end of a pre-installed vertical pile for permanent piling of the base structure to the seabed. During this period, at least temporarily support the sole solid support point of the base structure.

The solid support point can be arranged on the top of the side wall above sea level.

The solid support points can be located at different positions along the outside of the side wall. In still other embodiments, the solid support point can be configured at any position on the base structure, so that the solid support point is configured to receive the corresponding solid support point on the floating body and is preferably configured to be in line with the pre-installed vertical pile The ends are connected to at least temporarily support the base structure during piling operations to permanently pile the base structure to the seabed.

It should be understood that the solid support point on the floating body may be arranged at a position that enables it to be arranged/positioned above the solid support point of the base structure.

According to the embodiment, the wall structure can form an integral part of the base structure, and is strong The solid support points form an integral part of the wall structure.

As another option, a solid support point may be located on the sidewall or bottom surface of the base structure below sea level. In situations where a strong support point is positioned on the bottom surface, the pile may form a permanent part of the pile material system.

The base structure is supported by piles to the seabed using several permanent piles driven into the seabed, and the top of the pile is rigidly fixed to the base structure along the height of the side wall.

The seabed base layer 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 arranged along at least a part 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 detachably arranged on the top of the base structure in the wall structure to form an offshore unit supported by the seabed 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 base structure unit. In addition, the cantilever, beam or slab disposed at the top of the side wall forms an integral part of the wall structure, and its design and size are suitable for withstanding all temporary loads that occur during the piling process, Force and moment. For this purpose, cantilever beams, beams or slats can be provided with strong support points to function together with piles installed for temporary use.

It should be understood that the base of the floating body 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 force and load acting on the system during operation.

The wall structure of the seabed base structure ends above sea level. As shown in the diagram, some of the advantages of having a part of the seabed base structure above the water are:

a) The water plane helps reduce the uncertainty regarding stability during the installation of the seabed base structure.

b) The said part of the seabed structure will facilitate and simplify the floating entry and installation of the storage module.

c) The piling machine can be placed on the base structure above the horizontal plane, which reduces cost and time, and thus becomes unaffected by sea conditions during piling.

d) The base structure of the seabed is located above the water level, which means that it increases the defense against ship collision.

e) In some cases, some equipment (for example, cargo loading arms) may be installed on the seabed base structure and therefore installed at a certain distance from the floating body.

By providing beams or slats protruding outwards for the dock area, ships can be berthed at a certain distance from the vertical wall, thereby enhancing the ability to move and berth 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. In these areas, the water level can rise up to 8% above normal sea level in extreme conditions over 100 years. Meters to 9 meters. In this case, the tension rods arranged between the base structure and the floating body can bear a large part (if not all) of the lifting buoyancy force, and the other parts of the extreme temporary lifting force can be applied to 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 heavy weight of the liquid stored in the storage module (usually up to but not limited to 150,000 tonne (tonne) load, corresponding to the capacity of a large tanker). The large vertical load is transmitted to the seabed without any movement of the seabed transfer station. A certain part of this capacity can be obtained by increasing the height of the storage module while maintaining the horizontal occupation area of the seabed transfer station.

The following description of exemplary embodiments is made with reference to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements. The following detailed description does not limit the invention. Rather, the scope of the present invention is only defined by the scope of the attached patent application. For the sake of brevity, the following embodiment is about a method for installing the base structure in general The method of installing on the seabed and preferably (but not necessarily) on the inclined seabed and/or the seabed with low bearing capacity will be discussed.

The “one embodiment” or “an embodiment” mentioned throughout this specification means that a specific feature, structure or characteristic described in conjunction 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 quick and safe installation of the storage module using deck equipment, wherein the base structure is stably and rigidly supported during the piling operation of the permanent pile. With the pre-installed base foundation (which is stabilized at least by piles and aligned to the seabed in advance), the installation of the storage module can be completed within a few hours.

In addition, the present invention provides the possibility of establishing seabed transfer stations on different soil conditions. The density, composition, compactness, and morphology of seabed soil 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 on the possibility of finding a predictable and reliable basic solution for the seabed structure that will 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 piles to the seabed. In this case, the base structure can be pressurized as a semi-submersible structure and supported by piles to the seabed by the base structure and possibly (but not necessarily) the wall structure of the seabed base structure. In these cases, it is important to be able to efficiently transmit the vertical structural force, which has the following Advantages: The main structural beam of the base structure and the storage module have a mirrored structure interface. This means that the vertical force from the bulkhead of the storage module is preferably directly transferred to the main structural beam of the base structure and the pile structure and to the seabed. Calculations have shown that the piled seabed base structure must be able to tolerate and endure weights ranging from 100,000 to 120,000 tons.

Figure 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 row 14' is in the process of being forced into the seabed 30 by the piling barge 15 The piling barge 15 has 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 traditional seabed anchor (not shown in the figure) and mooring rope 18 (two in the figure). As shown, the pile 14 terminates at a predefined height above sea level 29.

FIG. 2 schematically shows that the base structure 10 is being towed by a towing vessel 19 and a pair of towing ropes 20 to a position between two rows of aligned piles 14. The base structure 10 includes two vertically arranged side walls 22, which are rigidly fixed to the bottom structure arranged in the middle, thereby forming a U-shaped mooring structure, which is configured as Used for berthing or mooring floating bodies 11. At the top of the vertically extending side walls 22, each side wall 22 is provided with a cantilever beam 21, 21' protruding outward, and the cantilever beams 21, 21' extend outward on each side of the base structure 10 from the top of the base structure 10 Extending laterally outwards completely along two parallel side walls 22, each cantilever beam 21, 21' is configured to rest on top of a corresponding row of piles 14. For this For this purpose, the cantilever beams 21, 21' are provided with solid support points 24 (not shown in Figure 2).

In addition, the floating body 11 is also provided with an overhanging section 50 extending laterally outward from the main body of the floating body 11 above the sea level 29, and the overhanging section 50 is configured to rest on each side of the base structure 10 The top surface of the vertical wall 22 is on and supported by the top surface of the vertical wall 22. In order to ensure the controlled transmission of loads and forces and to fix the floating body 11 to the base structure in a firm and safe manner, the bracket 51 is fixed to the interface surface on the overhanging section 50 on the floating body 11, and the The corresponding complementary bracket 52 is fixed to the supporting surface at the top of the wall 22. The two sets of brackets 51, 52 are bolted or fixed or welded together. It should be understood that the overhanging section 50 may be a section extending along the entire length of the side of the floating body or may be used as a separate overhanging unit along the floating body. Each side of the floating body 11 is placed separately in a spaced relationship. As shown in the figure, there is a certain interval between the inner surface of the side wall 22 of the base structure 10 and the side wall of the floating body 11.

Fig. 17 schematically shows a side view of the fixed state disclosed in Fig. 16, which shows details of the position of the floating body relative to the pile material and relative to the top surface of the base structure. As shown in the figure, there is also a space between the upper surface of the beam 26 and the lower bottom surface of the floating body, so that the ballast can be pumped out of the floating body 11 or pumped into the floating body 11. Changing the buoyancy of the floating body, the floating body is still fixed to the base structure by the bracket connectors 51 and 52.

As shown in FIG. 17, the pile 25 that is piled from above the sea level 29 ends below the sea level 29, thereby enabling simple and effective piling operations and reducing weight and cost. The pile casing can be closed at the top by a plate structure, and the bracket connectors 51, 52 can be positioned between two adjacent pile casings or on the top of the pile casing.

According to the disclosed embodiment, one or two columns of piles are exposed. However, it should be understood that the number of columns can be more than two.

In the disclosed embodiment, the pile is shown vertically oriented. However, it should be understood that one or more of the piles may be inclined downward and laterally outward relative to the base structure.

According to the illustrated embodiment, the pile terminates at the upper end surface of the side wall 22. However, it should be understood that the piles may terminate inside the side wall 22 at a lower level than the upper surface, thereby saving the length of the piles used.
