Description
Technical Field
The invention relates to a shuttle tanker, in particular to a bow loading device of the shuttle tanker.
Background
Shuttle tanker refers to a special tanker designed for transporting oil to and from offshore fields and on land. Because offshore terminal oil transfer requirements are high, most of the ships are provided with complex oil loading and unloading systems, dynamic positioning systems and helicopter platform facilities, and the cost of the ships is far higher than that of oil ships with the same tonnage. In the 80 s of the last century, China has built more 110000 t-grade shuttle tanker exports. Shuttle tankers (Shuttle tankers) are one of the important facilities in offshore oil production systems, and belong to relatively special ships with high added value. The cost is far higher than that of the traditional oil tanker.
When the existing shuttle tanker is used for bow loading and mooring, single-cable mooring is adopted, and the defect of unstable mooring exists.
In addition, the existing shuttle tanker adopts a shaft pin sensor for detecting the stress of the loading mooring rope, and the shaft pin sensor needs to be well assembled and fixed on a fixed shaft or a rotating shaft so as to ensure that a high-precision and high-repeatability measurement result is obtained, the standard shaft pin sensor only defines a force measuring direction, a correct force application angle can ensure to generate a zero output, a plurality of factors can influence the performance of the shaft pin sensor, the firm design of the shaft pin sensor can reduce the influence of bending force to the maximum limit, if the shaft pin sensor is influenced by the bending force during working, the overall precision can be reduced, the overall performance of the shaft pin sensor and a shaft hole can be influenced, the general H7 or G6 matching relation is recommended, but the ideal assembling relation can not be obtained frequently, and the loss can be caused on the repeatability and the non-linear performance, the overall ratio of load pressure and pin sensor is also often a design consideration.
On the existing shuttle tanker, when the stress of the loading mooring rope is detected in the process of retraction, the winding radius of the loading mooring rope on a winding drum is changed in the process of retraction of the loading mooring rope winch, so that the wrap angle of the force measuring pulley is changed therewith, and multiple experiments show that the change of the wrap angle of +/-8 degrees can bring about 1% stress detection error, so that in order to improve the detection precision, the stress detection part on the shuttle tanker needs to be improved, so that the problem of low detection precision is solved.
