Description
Technical Field
The invention relates to a remote intelligent anchoring and positioning safety evaluation system for a floating platform, and belongs to the technical field of ocean engineering and system development.
Background
Maritime work equipment can be generally divided into: floating operation platform and fixed operation platform. The floating operation platform is in a floating state during operation, the displacement of the platform is limited by the anchoring and positioning system (mainly comprising a winch, an anchor chain, an anchor cable and a seabed anchor) to keep the position, and the anchoring and positioning system is recovered after the operation is finished and goes to the next operation site, so that the floating operation platform has good maneuverability and can adapt to different geology, water depth and environmental conditions. Therefore, the method is widely applied to the offshore operation fields of wind power installation, operation and maintenance, hoisting, offshore installation and dismantling, oil gas and mineral resource exploitation and the like.
At present, when a floating type operation platform works on site, the arrangement of an anchoring and positioning system is mainly based on the design capability of the anchoring and positioning system, the number of broken anchors, the positions and angles of anchor points and the like are determined by site operators according to engineering experience and site environment, and accurate and effective calculation basis is lacked. The calculation report of the anchoring and positioning system provided by a design unit during ship delivery only gives a few typical working conditions, is difficult to adapt to anchoring and positioning operation in a multi-operation site, multi-water-depth and multi-seabed soil environment, and cannot be used as an operation basis for field operators.
The reasons for this are mainly that the floating platform anchoring and positioning safety assessment analysis based on frequency domain/time domain analysis is a complex system analysis process, the model is complex, the calculated amount is large, the man-machine interaction process is many (single working condition analysis needs to be completed by analysts with abundant experience in about 8 hours), and a set of complete and efficient special assessment tool is not available. Meanwhile, the ship end does not carry a large number of calculation models, install a large number of calculation analysis software and master the conditions of related analysis technologies, and when the field workers encounter difficulty in actual operation, the technical support of designers is difficult to obtain. Therefore, the field operator cannot perform safety evaluation analysis on the floating platform anchoring and positioning system according to the actual operating water depth, environmental conditions, seabed soil quality, hull weight gravity center state, an operating target and the like.
