Description

Technical Field

[0001] This utility model relates to the field of marine equipment technology, and in particular to a hydraulic sliding oil receiving tank for crude oil tankers. Background Technology

[0002] The global shipping industry is facing the dual challenges of an urgent need for green and low-carbon transformation and the need to upgrade its aging fleet. Suezmax crude oil tankers, with their moderate cargo capacity and main dimensions, can flexibly adapt to most ports worldwide and pass through the Suez Canal fully loaded, significantly shortening voyages and reducing transportation costs, demonstrating excellent economic performance on major crude oil routes from the Middle East and West Africa to Europe and the United States. However, with tankers over 20 years old accounting for 17% of the global fleet, the aging problem of the Suezmax fleet is particularly prominent. Older vessels generally suffer from low energy efficiency, excessive carbon emissions, and insufficient levels of intelligent technology, making it difficult to meet the EEDIPhase III energy efficiency standards and carbon intensity index (CII) requirements proposed by the International Maritime Organization (IMO). At the same time, increasingly stringent environmental regulations (such as the EU carbon tax and ship exhaust emission limits) and increased scrapping volumes have led to a structural capacity gap, resulting in a growing market demand for a new generation of energy-efficient and environmentally friendly Suezmax crude oil tankers.

[0003] Meanwhile, during the unloading of crude oil tankers at port roll-on / roll-off terminals, the long, flexible, and viscous nature of the loading and unloading hoses makes it difficult to completely clean them after the oil transfer is completed. This leads to residual oil leaking onto the outside of the ship's hull during disconnection and recovery, ultimately flowing into the ocean and causing environmental pollution. This problem not only exacerbates marine ecological risks but also contradicts the trend of green development in the shipping industry, urgently requiring a collaborative solution through ship design innovation and unloading process optimization.

The drive assembly 3 drives the sliding platform 1 to extend beyond the ship's side and retract back onto the ship's deck. The oil receiving flange 5 is positioned above the oil receiving tank 4, guiding oil leaking from the loading / unloading hose into the oil receiving tank 4. In this application, the drive assembly 3 drives the sliding platform 1 to slide along the slide rail component 2, enabling the sliding platform 1 to extend beyond the ship's side and retract back onto the ship's deck. When the sliding platform 1 extends beyond the ship's side, the oil receiving tank 4 on it can collect leaking oil. When the loading / unloading hose is disconnected, oil leaking from the hose connector can flow into the oil receiving tank 4, preventing oil from flowing into the sea and causing environmental pollution. Connecting the hose connector of the loading / unloading hose to the oil receiving flange 5 allows residual oil in the loading / unloading hose to be guided into the oil receiving tank 4 via the oil receiving flange 5, enabling oil recovery and improving economic efficiency. This application can prevent oil leakage during the disconnection and retraction of loading and unloading hoses. After the operation is completed, the sliding platform 1 is retracted back to the ship deck by the drive component 3, making the follow-up processing of offshore oil loading and unloading operations simpler and more convenient.

[0027] Preferably, a return oil hose 6 is connected to the bottom of the oil receiving tank 4, with one end of the return oil hose 6 connected to the oil receiving tank 4 and the other end connected to the oil recovery chamber. The return oil hose 6 allows for the recovery and reuse of leaked oil from the oil receiving tank 4, responding to the concept of green environmental protection and increasing economic benefits.

[0028] Preferably, the sliding platform 1 includes: a base plate 11, a railing 12 surrounding the base plate 11, and a handrail gangway 13 provided on the base plate 11. The handrail gangway 13 allows access to the base plate 11, and the railing 12 is used to prevent falls.

[0029] Preferably, the oil receiving trough 4 is mounted on the base plate 11, and the sliding platform 1 further includes a grille 14, which is mounted above the base plate 11. The grille 14 is positioned away from or above the oil receiving trough 4. In this embodiment, the grille 14 is located above the oil receiving trough 4, allowing leaked oil to enter the oil receiving trough 4 through the grille 14.

[0030] Specifically, the oil receiving flange 5 is installed above the base plate 11 via a bracket 51. The oil receiving flange 5 corresponds to the oil receiving groove 4, so that when the hose connector of the loading and unloading hose is connected to or disconnected from the oil receiving flange 5, the leaked oil can flow into the oil receiving groove 4. A guide pipe 52 is connected below the oil receiving flange 5, and the lower end of the guide pipe 52 is located in the oil receiving groove 4 for convenient oil collection.

[0031] Preferably, it also includes several fixed bases 7 fixed on the ship deck, and the slide rail component 2 is disposed on the fixed base 7. The fixed base 7 is used for the installation and support of the slide rail component 2.

[0032] Specifically, the fixed base 7 is welded from steel plates and installed on the ship deck to bear the load of the sliding platform 1 and the pushing load of the slide rail component 2.

[0033] Preferably, the slide rail component 2 includes a guide rail 21 and a sliding support block 22 that slides along the guide rail 21. The guide rail 21 is mounted on several fixed bases 7, and the sliding support block 22 is fixedly connected to the sliding platform 1. The slide rail component 2 is used to support the sliding platform 1 and prevent it from drooping.

[0034] Preferably, the drive assembly 3 includes a hydraulic control station 31, hydraulic lines 32, and a hydraulic cylinder 33. One end of the hydraulic cylinder 33 is connected to the ship's deck, and the other end is connected to the sliding platform 1. The hydraulic control station 31 is used to control the input or output of the working medium to the hydraulic cylinder 33 through the hydraulic lines 32, thereby controlling the extension and retraction of the hydraulic cylinder 33.

[0035] Preferably, the hydraulic cylinder 33 is located below the sliding platform 1 to reduce the space occupied; the cylinder body of the hydraulic cylinder 33 is hinged to the ship's deck on the chord side, and the piston rod is hinged to the bottom of the sliding platform 1. The extension and retraction of the hydraulic cylinder 33 pushes the sliding platform 1 to retract.

[0036] The working principle of the device in this application is as follows:

[0037] After the oil loading and unloading operation is completed, the hydraulic control station 31 is activated to control the hydraulic cylinder 33 to retract, causing the sliding platform 1 to extend outward to the working position. The operator then climbs onto the sliding platform 1 to connect the loading / unloading hose connector to the oil receiving flange 5. At this time, oil will leak into the oil receiving tank 4. The hydraulic cylinder 33 is then pushed outward, causing the sliding platform 1 to return to its initial position. The leaked oil in the oil receiving tank 4 is then discharged into the storage tank through the return oil hose 6.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
