Description

SELF-FLOATING SUPER SHALLOW WATER STRUCTURESCROSS REFERENCE TO RELATED APPLICATIONS[1] This application claims the benefit of Provisional U.S. Patent Application Number US 63 / 605,000, filed on December 1, 2023, which is incorporated by reference herein by reference in its entirety.FIELD OF THE INVENTION[2] The present invention relates to advancements in offshore structural technology, specifically focusing on a new generation of self-floating offshore structures. The Super Shallow Water Structures (SSS) of the present invention are designed and manufactured for installation in shallow water areas, typically ranging from 3.5 meters to 50 meters in depth.BACKGROUND[3] Traditional offshore installations involve complex and costly processes, requiring the transportation of individual components such as the jacket and deck on separate material barges, followed by offshore lifting using specialized Derrick Barges or heavy lift vessels. Jackets are temporarily stabilized on mudmats until driven or drill & grouted piles are installed. This traditional method also involves extensive use of high-cost equipment, such as Derrick Barges (DB) or Dynamic Positioning vessels (DP2), which are essential for heavy lifting and positioning at the installation site. The limited availability of such vessels, coupled with their extremely high daily rates, makes this method increasingly expensive and less viable, particularly in a busy offshore market.[4] In contrast, the Super Shallow Water Structure (SSS) of the present invention eliminates the need for heavy lifting vessels by integrating the entire structure into a single self-floating unit. The steel foundation of the Super Shallow Water Structure (SSS) is designed and manufactured to function as a built-in material barge or a double pontoon vessel, capable of floating with the complete assembly — jacket, deck, and topsides — intact. The stability of the Super Shallow Water Structure (SSS) during transportation is carefully engineered to meet transportation criteria, and buoyancy tanks (3) or retractable sections may be incorporated to ensure stability before towing.[5] The structure is fabricated with a modular approach. In cases where fabrication yard or dry dock capabilities allow, the Super Shallow Water Structure (SSS) of the present invention is constructed as a single integrated module. Alternatively, the Super Shallow Water Structure (SSS) can be fabricated in three separate modules, which are assembled either in a dry dock or at a quay side, allowing for accelerated schedules. Some compartments of the structure are partially or fully filled with grout prior to sailing to minimize the time spent offshore at the target site.[6] Upon arrival at the offshore location, the Super Shallow Water Structure (SSS) of the present invention is lowered into position by filling select compartments with water, a process that is carefully controlled to ensure that the structure sinks gradually to the seabed without exceeding a load of 10 to 20 tonnes. A crane with minimal lifting capacity (< 50 tonnes), positioned on any available vessel type, is used to secure the lowering process. After the Super Shallow Water Structure (SSS) reaches its final, leveled position, the crane is dismantled, and hoses are connected by divers to complete the filling of the remaining compartments, thereby finalizing the installation process.[7] In certain scenarios, additional topsides modules may be lifted and installed on the deck (4) of the Super Shallow Water Structure (SSS), with each module weighing less than 100 tonnes. This method avoids the need for a heavy lift vessel by utilizing the Super Shallow Water Structure's inherent stability during installation.[8] One of the key advantages of the Super Shallow Water Structure (SSS) of the present invention is its significant reduction in installation time and cost. Unlike conventional offshore structures, which can require several weeks for jacket, piling, and deck installation, the entire installation process of the Super Shallow Water Structure (SSS) of the present invention can be completed within 24 hours once at the target site. Furthermore, the Super Shallow Water Structure (SSS) of the present invention provides the additional benefit of being re-float, making it possible to relocate and re-install the structure at different locations, further enhancing its versatility and cost-effectiveness.[9] Overall, the Super Shallow Water Structure (SSS) represents a breakthrough in offshore structure design and installation, offering a simpler, faster, and more cost-effective solution compared to traditional methods, particularly for shallow water applications.SUMMARY

[0061] The present invention relates to Super Shallow Water Structures (SSS), a novel generation of offshore structures designed and manufactured for shallow water areas, typically between 3.5 meters and 50 meters in depth. These self-floating structures are capable of being towed from a fabrication yard or dry dock to an offshore location and lowered into place without the need for offshore lifting operations, heavy-lift vessels, or barges. The current invention provides an efficient, cost-effective, and rapid method for installing offshore structures with reduced complexity and fewer requirements for specialized equipment.

[0062] The Super Shallow Water Structure (SSS) consists of several key components designed and manufactured to work together to facilitate easy transportation, installation, and potential relocation. These components include four essential parts as shown below:

[0063] Part 1: Pontoon Foundation (1)The Pontoon Foundation (1) forms the base of the structure and serves a dual purpose: it functions as both the floating transport vessel and as the gravity-based foundation once submerged. The pontoon foundation (1) is a ship-like steel structure that includes internal compartments which can be filled with grout, alternative materials, or water to control buoyancy and stability to make the Super Shallow Water Structure (SSS) has the below distinctive features:

[0064] 1- Buoyancy and Stability Control:The internal compartments of the pontoon are partially or fully filled with grout, water, oralternative materials. This filling can be done in stages: part of the filling may occur before the structure is towed to the offshore site, while the rest is done on-site either before or after the structure is lowered to the seabed.

[0065] 2- Self-Floating Capability:The Pontoon Foundation (1) enables the entire structure (including the deck and jacket) to be towed as a self-floating unit. Upon reaching the installation site, water is added to selected compartments to gradually lower the structure into its final position on the seabed.

[0066] 3- Gravity-Based FoundationAfter the pontoon is lowered and settled on the seabed, the final filling of grout and / or water converts the pontoon into a gravity-based foundation that securely anchors the structure to the seabed.

[0067] 3- Re-float and Relocation:A key novel feature of this invention is the ability to re-float and relocate the entire structure. This is achieved by reversing the filling process: water-filled compartments can be emptied, and additional buoyancy can be attached if required, allowing the structure to be towed to another location if necessary.

[0068] Fig. 3 shows the structural arrangements for the pontoon foundation (1).

[0069] Part 2: Additional Buoyancy Attachments (Optional):In some cases, buoyancy tanks (3) or retractable buoyant sections are added to the Pontoon Foundation (1) prior to towing the structure to the installation site. These additional buoyancy elements provide extra lift during the transportation phase and can be removed or retracted before or after the structure is lowered onto the seabed. The use of additional buoyancy is optional and is employed depending on specific transportation or stability requirements.

[0070] Part 3: Braced Legs (2):The Braced Legs (2) component is a pile-free jacket structure embedded into the gravitybased pontoon foundation (1). These legs are designed and manufactured to stabilize the structure once it is set on the seabed. The legs are connected at the bottom to the pontoon foundation (1) and at the top to the deck legs, providing structural support and resistance to lateral forces such as waves and wind. The braced legs (2) allow the structure to maintain its position during the entire installation process and throughout its operational life.

[0071] Part 4: Deck (4):The deck (4) is a single or multi-deck structure that serves as the platform for topside equipment, such as wellheads, processing facilities, or accommodation modules. The deck (4) is connected to the braced legs (2) of the jacket structure, providing the necessary support for heavy equipment. Unlike traditional offshore structures, which rely on piles for stability, the deck (4) of the Structure (SSS) is connected to the jacket legs, enabling easier and faster installation.

[0072] Design Concept and Installation Process of the present invention:The design of the Structure (SSS) is optimized for rapid and economical offshore installation in shallow waters. The overall concept focuses on eliminating the need for offshore lifting operations and reducing the costs associated with traditional heavy-lift vessels and barge transportation.

[0073] Fabrication Process

[0074] The steel foundation of the Super Shallow Water Structure (SSS) is specifically designed and fabricated to function as a built-in material barge or double pontoon vessel, allowing it to float with the entire SSS assembly, including the jacket, deck, and topsides. The design of the foundation ensures that the Structure (SSS) remains stable and buoyant throughout the transportation process.

[0075] The stability of the entire SSS assembly is carefully engineered to meet transportation requirements. In certain cases, additional buoyancy tanks (3) or retractable buoyant sections may be attached to the floating foundation before towing to further enhance stability. These additional buoyancy features ensure that the structure maintains optimal balance and safety during transit.

[0076] As shown in Figure 9, the floating foundation's design and the integration of these buoyant components play a crucial role in enabling the seamless transportation of the SSS to the offshore site, ensuring that the structure can be towed efficiently and without the need for sea-fastening of SSS on transportation vessels.

[0077] The steel foundation of the Super Shallow Water Structure (SSS) is designed to function similarly to a vessel, albeit on a considerably smaller scale. The internal structure consists of multiple compartments formed by longitudinal and transverse bulkheads, which are essential for ensuring structure integrity during transportation and installation, moreover enablingselected filling of various compartments. As described in Figure 5, the top plate (not shown for clarity) features nozzles equipped with manual valves, which allow for controlled filling of the compartments with water and grout, based on the specific requirements of each installation.

[0078] To optimize installation time and minimize offshore operations, it is recommended to pre-fill some or all of the compartments with grout prior to sailing, provided that the stability of the structure permits. This partial or full grout filling before reaching the offshore site helps reduce the time spent on-site and enhances the efficiency of the lowering process.

[0079] Regarding fabrication, the Structure (SSS) can be constructed as a single integrated module if the capabilities of the fabrication yard or dry dock allow. In cases where accelerated schedules are required, the Structure (SSS) can also be fabricated as three separate modules. These modules are fabricated in series or parallel, depending on the project timeline, and are then assembled either in the dry dock or in the water at the quay side. During fabrication, certain compartments may be pre-filled with grout or other alternative material to further streamline the towing and installation process. As illustrated in Figure 6, this modular approach allows for greater flexibility and efficiency in the construction and installation of the Structure (SSS), ensuring that it is ready for deployment with minimal delays.

[0080] Installation Process1) Towing to Site:Upon completion of fabrication, the Structure (SSS) is towed to the installation site using tugboats or other suitable vessels. During transportation, the structure remains selffloating due to the pontoon foundation's buoyancy.In Figure 7, the inventor shows the structure of the present invention during towing its designation location.2) Lowering to Seabed:Upon arrival at the site, hoses are connected to selected compartments of the pontoon foundation (1), and water is pumped into the compartments in a defined sequence. This controlled filling causes the structure to sink gently to the seabed, with the load not exceeding 10-20 tons. A crane with a minimal lifting capacity (less than 50 tons) can beused to assist in the lowering process, ensuring smooth and controlled positioning of the structure.In Figure 8, the inventor shows the structure of the present invention when it is lowered onto seabed in location.3) Final Positioning and Securing:Once the structure has been lowered and leveled on the seabed, the crane is dismantled, and hoses are connected by divers to complete the filling of the pontoon compartments with water and / or grout. Upon completion of the filling process, the hoses are retracted, and the structure is securely anchored in place as a gravity-based foundation.4) Topside Installation (Optional)In some cases, additional topsides modules may be installed on the deck (4), maintaining the lift load of each additional module below 100 tonnes.. These modules are lifted and installed using cranes or other lifting equipment available on-site, eliminating the need for large, expensive heavy-lift vessels.According to the above description of the present invention, the Super Shallow Water Structure of the present invention provides several key advantages over conventional offshore installations:

[0081] No Need for Heavy Lift Vessels: The Structure (SSS) does not require heavy-lift vessels or complicated lifting operations, reducing both installation costs and the time required for offshore operations.

[0082] Reduced Installation Time: Once on-site, the installation of the Structure (SSS) can typically be completed in under 24 hours, compared to the several weeks required for traditional jacket and piling installations followed by deck installation.

[0083] Cost Savings: The use of a self-floating system and the avoidance of heavy-lift vessels and barges result in substantial cost savings for offshore installations.

[0084] Flexibility in Relocation: The Structure (SSS) can be re-floated, relocated, and reinstalled at a different site, offering operational flexibility and reducing the need for new structures in some cases.

[0085] Multi-Purpose Application: While the Structure (SSS) is primarily intended for oil and gas applications (such as wellhead towers, flare towers, and processing facilities), it can alsobe adapted for other offshore industries requiring cost-effective and rapid installation in shallow waters.

[0086] ConclusionThe Super Shallow Water Structure (SSS) represents a significant advancement in offshore structure design and installation. By combining self-floating capabilities with a gravity-based foundation and eliminating the need for heavy-lift vessels, the Structure (SSS) provides a cost-effective, efficient, and flexible solution for shallow- water offshore projects.
