Technical Field
[0001] This invention relates to the field of marine engineering technology, specifically to an efficient oil tanker transshipment system and method based on single-point mooring. Background Technology
[0002] In maritime oil transportation and transshipment, single-point mooring systems (SPMs) are widely used as crucial offshore facilities for oil tanker berthing and cargo transfer operations. However, traditional SPMs suffer from numerous problems in practical applications, limiting their operational efficiency and safety. Firstly, in multi-vessel collaborative operations, traditional SPMs are inefficient, struggling to achieve efficient coordination between vessels, leading to prolonged operation times and significant resource waste. Secondly, precise control of safety distances is difficult, increasing the risk of collisions during mooring and transshipment, posing substantial safety hazards. Furthermore, tank sloshing remains a persistent problem for traditional SPMs. Under the influence of wind and waves, the liquid in the tanks sloshes violently, damaging the hull structure and potentially causing leaks. Simultaneously, poor mooring stability allows vessels to easily shift due to environmental factors while moored, affecting the accuracy of transshipment operations. Finally, traditional SPMs lack sufficient resistance to wind and waves. In severe sea conditions, vessels struggle to maintain stability, hindering transshipment operations and severely limiting the efficiency and safety of maritime oil transportation and transshipment. To address the aforementioned issues, there is an urgent need for a new single-point mooring system and method that can improve the efficiency of multi-vehicle coordination, precisely control safe distances, effectively suppress tank sloshing, enhance mooring stability, and improve resistance to wind and waves, in order to meet the needs of modern maritime oil transportation and transshipment.

This indicates the weighting coefficient for the safety impact of oil tanker spacing. , and Calculations using the Analytic Hierarchy Process (AHP) show that the weight of the influence of ship motion is 0.3-0.4 when the wave level is <5, and increases to 0.5-0.6 when the wave level is >5. denoted as the minimum safe distance (m) between the i-th monitoring point and surrounding oil tankers, and n represents the number of monitoring points.
[0035] The advantage is that it allows for the calculation of the optimal mooring point location. This serves as the basis for the mooring point optimization configuration module, and automatic anchoring positioning correction is performed to reduce the amplitude of hull movement, thereby reducing the risk of collision and capsizing, and thus improving the stability and safety of mooring.
[0036] The wind and wave resistance enhancement module includes an anchor chain strength enhancement unit, an active tension adjustment unit, and a dynamic ballast balance unit; The anchor chain strength enhancement unit replaces traditional steel with UHMWPE fiber (ultra-high molecular weight polyethylene fiber, with a molecular weight ≥ 3 million). UHMWPE fiber anchor chains are 40% lighter than traditional steel anchor chains, have a 25% higher breaking strength, and extend their seawater corrosion resistance to 15 years. This lightweight design of the anchor chain enhances its fatigue resistance and corrosion resistance. The active tension adjustment unit receives dynamic data on the force of the mooring cable through a real-time dynamic monitoring module, and automatically controls the tension adjustment device to dynamically adjust the pretension of the mooring cable, thereby enhancing the stability and wave resistance of the mooring system. The dynamic ballast balance unit acquires real-time dynamic data of the ship's attitude and environmental parameters through a real-time dynamic monitoring module, automatically adjusts the water distribution in the oil tanker's ballast tanks, and performs hull balance control to enhance the stability of the oil tanker in wind and waves. This invention employs a pontoon-type single-point mooring system. This system utilizes specially designed high-strength anchoring pontoons (made of marine engineering-grade composite materials, impact-resistant and seawater corrosion-resistant), integrated with quick-connect interfaces for mooring cables, and reinforced with anchor chain strength units. This constructs a flexible mooring system of "pontoon-lightweight anchor chain-hull." When encountering wind and waves, the pontoons can absorb surge energy through their own vertical and horizontal flexible buffering. Combined with an active tension adjustment unit, the mooring tension is dynamically adjusted to further reduce the hull's sway amplitude. Simultaneously, a dynamic ballast balancing unit adjusts the ballast in conjunction, allowing for a better fit between the pontoons and the hull's attitude. This triple synergy enhances the ship's resistance to wind and waves.
[0037] The advantages are: by establishing an anchor chain strength enhancement unit, an active tension adjustment unit, and a dynamic ballast balance unit, the anchor chain strength enhancement unit uses recyclable UHMWPE fiber anchor chains to reduce material loss; the dynamic ballast balance unit optimizes the ballast water regulation frequency through intelligent algorithms, reducing pump energy consumption (saving 15%-20% energy compared to traditional regulation methods), and has an oil spill warning function. It monitors the hull sealing in real time through liquid tank pressure sensors, and closes the transfer valves in case of abnormalities, which meets the environmental requirements of the IMO (International Maritime Organization). It uses high-strength materials, monitors and adjusts tension in real time, and automatically controls the hull balance to enhance anchor chain performance, mooring system stability, and oil tanker stability, thereby effectively coping with complex or extreme sea conditions. Finally, the system solves the problem of insufficient wind and wave resistance of the mooring system.
[0038] The multi-ship collaborative transshipment module is based on the collaborative carrying capacity of multiple oil tankers. Intelligent scheduling of work queues is performed, berthing order is allocated according to tonnage priority, and dynamic safety distance between oil tankers is considered. It conducts collision warnings and path planning, and adjusts the distance between ships in real time to above the safety threshold; In the multi-vehicle collaborative transshipment module, the intelligent arrangement of the work queue adopts an improved genetic algorithm, and the objective functions include minimizing the operation time and maximizing the safe distance. The tank sloshing suppression module is designed to suppress the sloshing energy in the tanker's liquid tanks. Active anti-sway control is implemented, driving the adjustable mass block inside the tank to move in the opposite direction to counteract the swaying kinetic energy. The adjustable mass block of the liquid tank sway suppression module has a response frequency of 0.5-5Hz and a sway energy suppression rate of ≥70% (under the condition of an effective wave height of 3m). Among them, the active anti-sway control adjusts the stroke of the mass block in real time according to the liquid level in the liquid tank. When the liquid level is <50%, the stroke is amplified by 1.2 times. The mooring point optimization configuration module is based on the optimal mooring point location. Automatic anchoring and positioning correction is performed. The anchor chain length is finely adjusted through the winch system to ensure that the deviation between the ship's position and the calculated value is less than 0.5°, and the accuracy of automatic anchoring and positioning correction is ≤0.5m. The yaw angle of the ship is controlled within ±2°.
[0039] The advantages are: through the joint collaboration of the multi-vehicle collaborative transshipment module, the liquid tank sloshing suppression module and the mooring point optimization configuration module, a series of operations are carried out, including operation queue arrangement, collision warning, path planning, active roll reduction and anchoring positioning correction, thereby achieving the goals of efficient and safe multi-vehicle transshipment, reducing the impact of liquid tank sloshing and optimizing mooring position. Finally, the system solves the problems of low operation efficiency and high safety risk.
