Offshore oil platform based ocean vertical section automatic observation system and method

Abstract

The invention belongs to the field of marine observation, in particular to an offshore oil platform based ocean vertical section automatic observation system and method, two winches are installed on abottom layer platform, a fixed pulley group is welded on the lower surface of a top layer platform, a load-bearing communication cable is led out from the winch A, bypasses the fixed pulley group andthen goes into the ocean, the load-bearing communication cable returns to the other winch after passing by a movable pulley group on an anchoring weight, a locating steel cable is hung from the fixedpulley group on the top layer platform, the bottom end of the locating steel cable is connected to the anchoring weight, an observation device is adhered on the load-bearing communication cable and moves up and down along with the load-bearing communication cable, data are acquired in the moving process, the two winches are controlled by a central control device in the moving process. A battery is changed and the data are downloaded when the equipment is regularly maintained; the full section of the ocean is observed through the single observation device, and the system has the characteristics of stable and reliable operation, low energy consumption and the like.

Description

technical field [0001] The invention belongs to the field of ocean observation, in particular to an ocean vertical profile automatic observation system and method based on an offshore oil platform. Background technique [0002] The 21st century is the century of the ocean, and at the same time, the ocean is also a hot spot for energy extraction. For example, my country's Nansha sea area is rich in oil reserves and has good prospects and conditions for oil and gas development. In order to exploit oil at sea and ensure the safety of offshore oil platforms, it is necessary to have a full understanding of the marine environment that has a major role and influence on offshore engineering facilities. Actual observations show that the major effects and influences on marine engineering facilities in the ocean are mainly ocean internal waves and currents. Internal wave is one of the disastrous marine environments. The internal wave flow in the ocean can generate huge horizontal thr...

Problems solved by technology

[0003] At present, the monitoring of the changes in the marine hydrological environment around the oil platform is multi-sampling. Submersible markers are deployed around the platform, or equipment is manually hoisted on the oil platform for observation. Stereoscopic observation, manual lifting of equipment is time-consuming and laborious
