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

Abstract

The invention belongs to the field of marine observation, and specifically provides a double-winch marine hydrological observation system and method based on an offshore oil platform. Two winches areinstalled on an underlying platform separately, and the lower surface of a top platform is welded with a plurality of fixed pulley blocks; mooring wire ropes enter the sea after being led out from a winch A and passing around the fixed pulley blocks, and the mooring wire ropes are returned to a winch B after passing around a movable pulley block on an anchoring weight; a locating wire rope is hungdown from the fixed pulley blocks below the top platform, and the bottom end of the locating wire rope is connected to the anchoring weight; a hydrological observation device is attached to the mooring wire ropes, and installed in a platform hanging manner; measuring equipment works in a self-contained mode, and is powered by a battery; data is saved automatically; and the battery can be replacedduring periodic maintenance of the equipment, and the data is downloaded. According to the marine hydrological observation system, lifting of the anchoring weight is not required during maintenance of the hydrological observation device, and the marine hydrological observation system has the characteristics that the mooring wire ropes are not kinked, the weight is not spun, and the equipment is easy to maintain.

Description

technical field [0001] The invention belongs to the field of marine observation, in particular to a double winch marine hydrological 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...
