Problems solved by technology

The design of the riser system in the related art is generally based on industry norms and standards. This kind of riser system may have the disadvantage that the assumed environmental load is different from the actual one.
In addition, due to the limitations of the calculation and analysis model of the riser, the damage of the riser may be uncertain, and there may be deviations between the actual installation of the riser and the analysis model, and it is impossible to accurately reflect the effect on the riser only through the preliminary design. The true load and actual stress of
Although at the beginning of the design of the riser system, the strength of the riser was solved by means of improving the design standard or increasing the safety factor, the damage or failure of the riser still occurred from time to time

Abstract

The invention discloses a deepwater-riser integrated data collecting device and a data storing method thereof. The deepwater-riser integrated data collecting device comprises a data collecting assembly, a motion processor, microcontroller with an FAT file system, a timer, a temporary storage, a storage, an output interface and a power supplying assembly. The data connecting device comprises a three-axis acceleration sensor and a three-axis angular velocity sensor which are used for being matched with the motion characteristics of a deepwater riser; the input end of the motion processor is respectively connected with the three-axis acceleration sensor and the three-axis angular velocity sensor; the microcontroller is connected with the output end of the motion processor; the input end of the temporary storage is connected with the microcontroller, and the output end of the temporary storage is connected with the storage; the storage is connected with the microcontroller through the temporary storage; the output interface is connected with the microcontroller; the power supplying assembly is respectively connected with the microcontroller and the storage. By means of the deepwater-riser integrated data collecting device, working power consumption of the whole device can be reduced, and the working time is shortened.

Description

technical field [0001] The present invention relates to the technical field of offshore petroleum engineering, in particular to an integrated deepwater riser data acquisition device and a data storage method thereof. Background technique [0002] In the field of offshore petroleum engineering, the riser system is the conduit connecting the floating installation on the water surface and the subsea equipment (such as wellhead, PLEM, header) located on the seabed. The design of the standpipe system in the related art is generally based on industry norms and standards. This kind of riser system may have the disadvantage that the assumed environmental load is different from the actual one. In addition, due to the limitations of the calculation and analysis model of the riser, the damage of the riser may be uncertain, and there may be deviations between the actual installation of the riser and the analysis model, and it is impossible to accurately reflect the effect on the riser o...
