Arranging and recovering system for marine operation

Abstract

The invention provides an arranging and recovering system for marine operation. The system comprises a traction assembly and a wave compensation device. The traction assembly comprises a winch, a winch rotating shaft arranged in the winch, and a winch drive part connected with the winch rotating shaft in a driving manner. The winch rotating shaft is installed on the winch in a rotating manner. Thewave compensation device comprises a controller, a detecting assembly used for detecting the relative rotating angle of the winch and the winch rotating shaft, a transmission gear used for transferring drive torque of the winch rotating shaft to the winch, and a compensation gear used for adjusting the relative rotating angle of the winch and the winch rotating shaft. The controller generates a control instruction to the compensation gear according to the detection signal of the detecting assembly, thus output torque of the compensation gear is adjusted, and the transmission gear and the compensation gear are arranged in the winch, and are in engaged transmission with the winch. The system has the advantages of being convenient to operate, good in wave compensation effect, small in occupied space, and high in safety and reliablity.

Description

technical field [0001] The invention relates to the field of offshore operations, in particular to a deployment and recovery system for offshore operations. Background technique [0002] The ocean area occupies 70% of the total area of ​​the earth, which contains rich fishery, oil and gas and mineral resources. In order to effectively develop seabed resources, the scope of human operations has gradually extended to different sea areas, and underwater robots and underwater platforms with various operating functions and performances have been developed one after another. [0003] The deployment and recovery system for offshore operations can realize the deployment and recovery of underwater operation equipment, and it is widely used in the field of offshore operations. The deployment and recovery system is installed on the working mother ship. Usually, the winch drive directly drives the winch and the shaft to rotate together or directly drives the winch to rotate, and realiz...

Problems solved by technology

However, due to the large moment of inertia of the winch, the required capacity of the winch driving parts is large. Therefore, the delay of the corresponding compensation control system is large, resulting in a complex control system (need to add a large number of sensors, hull attitude calculation, prediction, etc.), and the wave compensation effect At the same time, if the design of the wave compensation control algorithm is unreasonable, it will not only fail to achieve the effect of wave compensation, but will even aggravate the damage of the wave to the deployed recovery system.
