Multiple point mooring anchor and paddle joint cooperative positioning system and method of ship ocean engineering

Abstract

The invention provides a multiple point mooring anchor and paddle joint cooperative positioning system and method of ship ocean engineering. The multiple point mooring anchor and paddle joint cooperative positioning system comprises an upper computer, a mooring winch control system and an electric propulsion control system; the mooring winch control system comprises four sets of windlass systems which are connected together through a first field bus to constitute an annular network; the electric propulsion control system comprises four sets of electric propulsion systems which are connected together through a second field bus to constitute an annular network; and the first field bus and the second field bus are connected together to achieve isochronous and synchronous control over the mooring winch control system and the electric propulsion control system. The multiple point mooring anchor and paddle joint cooperative positioning system and method have the advantages that through multiple point mooring anchor-paddle joint cooperative positioning, the advantages of stability, high efficiency, energy saving and low cost are brought to maritime work positioning items, the resource utilization rate of propulsion equipment is high, the capacity of mooring equipment is further decreased, and important practical significance and promotional value for improving competitiveness of the positioning items such as offshore drilling and oil production are achieved.

Description

technical field [0001] The invention belongs to the technical field of ships and marine engineering, and in particular relates to a system and method for multi-point mooring, anchor and propeller joint cooperative positioning in ship and marine engineering. Background technique [0002] The working mode of the floating offshore platform / engineering ship is mostly to work in a certain sea area for long-term positioning, and can be moored in a small area. The positioning technology and method are very critical. Multi-point mooring is one of the positioning modes of floating offshore platforms / engineering vessels. Its application scenarios include: the length and width of floating bodies are close, or the directionality of environmental forces is relatively single, or floating offshore drilling platforms require fixed-point positioning, or in In narrow sea areas, river courses, etc., floating bodies that are not allowed to rotate 360° in marine engineering construction operatio...

Problems solved by technology

However, DP dynamic positioning is the most complex power and control system, and it is mostly used in high value-added projects; the cost of offshore oil exploitation is much higher than that of land oil exploitation. Therefore, the joint positioning method combining mooring and DP dynamic positioning, Development is still limited due to issues such as high cost and high energy consumption
