Description

Technical Field

[0001] The present application relates to the technical field of crude oil transportation, and in particular to a supporting structure of a crude oil transportation pipeline and an oil tanker. Background Art

[0002] When oil tankers transport crude oil, the viscosity of the crude oil in the pipeline will change with the temperature. The higher the temperature, the lower the viscosity of the crude oil. In the process of transporting crude oil, if the temperature of the crude oil in the pipeline is too low, the viscosity of the crude oil will become very large, resulting in reduced fluidity of the crude oil in the pipeline, making it difficult or even impossible for the crude oil to flow. Therefore, when transporting crude oil, the crude oil must be heated to a certain degree to ensure that the crude oil can flow smoothly in the pipeline.

[0003] However, when the heated crude oil flows through the pipeline, the pipeline will undergo thermal expansion or thermal contraction, which may cause the pipeline to shift or cause thermal stress in the tee, elbow and other parts, causing the weld to be strained. For this reason, the relevant technology considers using a bracket fixed on the hull to support the pipeline used to transport crude oil, and the bracket is used to withstand the horizontal thrust generated by the thermal expansion or thermal contraction of the pipeline. However, the above method will cause the pipeline and the bracket to be subjected to thermal stress, which may cause the pipeline and the bracket to be strained. Utility Model Content

[0032] When oil tankers transport crude oil, the viscosity of the crude oil in the pipeline will change with the temperature. The higher the temperature, the lower the viscosity of the crude oil. In the process of transporting crude oil, if the temperature of the crude oil in the pipeline is too low, the viscosity of the crude oil will become very large, resulting in reduced fluidity of the crude oil in the pipeline, making it difficult or even impossible for the crude oil to flow. Therefore, when transporting crude oil, the crude oil must be heated to a certain degree to ensure that the crude oil can flow smoothly in the pipeline.

[0033] However, when the heated crude oil flows through the pipeline, the pipeline will undergo thermal expansion or thermal contraction. In severe cases, the pipeline may be displaced or thermal stress may be generated in the tee, elbow and other parts, causing the weld to be damaged. For this reason, the related art considers using a bracket fixed to the hull to support the pipeline used to transport crude oil, and the bracket is used to withstand the horizontal thrust generated by the thermal expansion or thermal contraction of the pipeline. However, the above method will cause the pipeline and the bracket to be subjected to thermal stress, which may cause the pipeline and the bracket to be damaged. For this reason, it is urgent to optimize the traditional bracket to solve the above technical problems. The support structure of the crude oil transportation pipeline optimized by this application will be described in detail below in conjunction with the accompanying drawings.

[0034] Reference Figures 1 to 6 , a supporting structure for a crude oil transportation pipeline according to an embodiment of the present application, used for an oil tanker, includes a bracket and a guide rail structure.

[0036] When the support structure of the crude oil transportation pipeline in the embodiment of the present application is in use, the pipeline a for transporting crude oil is supported by the bracket. When the pipeline a expands or contracts due to heat, the bracket can slide relative to the guide rail structure along the length direction of the pipeline a as the pipeline a deforms, thereby helping to reduce the thermal stress on the pipeline a and the bracket, and further helping to reduce the risk of the pipeline a and the bracket being strained.

By providing the thermal insulation pad 700, it is helpful to prevent the heat of the crude oil in the pipeline a from being transferred to the hull of the oil tanker during the transportation of crude oil, which is helpful to reduce the heat loss of the crude oil to ensure the fluidity of the crude oil in the pipeline a. At the same time, it is helpful to protect the hull of the oil tanker. In addition, it is also helpful to prevent the crew on the oil tanker from being scalded.
