Active heave compensation simulation method and apparatus based on marine floating crane operation requirement

Abstract

The invention provides an active heave compensation simulation method and apparatus based on a marine floating crane operation requirement, and belongs to the field of marine engineering. The active heave compensation simulation method based on the marine floating crane operation requirement comprises following steps: S1, wave generation; S2, detection of heaving motion, rolling motion and pitching motion; S3, equipment input; S4, control of a thread by a server; and S5, driving of the thread. The active heave compensation simulation apparatus comprises a base, a motion platform is arranged on the base, a manipulator is arranged on the motion platform, the motion platform comprises an upper platform, a first motor, a second motor and a third motor, output shafts of the first motor, the second motor and the third motor are respectively hinged to a first support, a second support and a third support, and the first support, the second support and the third support are respectively provided with a first universal joint, a second universal joint and a third universal joint. According to the method and apparatus, the severe marine environment can be simulated, the method and apparatus can be used for testing different control methods and trainings, and the risk degree of the practical marine floating crane operation requirement is reduced.

Description

technical field [0001] The invention belongs to the field of ocean engineering, and relates to an active wave compensation simulation device and method, in particular to an active wave compensation simulation method and device based on the requirements of offshore floating crane operations. Background technique [0002] In recent decades, the marine industry has been seen as a growing point of interest in the development of new technologies and related marine equipment to meet the continuously growing needs of the marine industry. At present, the operation of offshore equipment is highly uncertain, which will lead to accidents. In such a challenging operating environment, offshore floating cranes will play an important role in transportation and hoisting operations. [0003] In the rough sea environment, there will be many problems in the operation of offshore floating cranes, such as swaying, precise positioning, collision avoidance and operation safety. In most cases, the...

Problems solved by technology

Such controls, which rely solely on the operator's extensive experience and high level of skill, will be difficult to manage when efficiency and safety are considered

In particular, when a large wave occurs in an extreme marine environment, such unreliable control will not be possible manually

At the same time, a lot of money is invested in training operators, which will generate a lot of waste, because it cannot be trained in a really harsh environment, and it is very difficult to test new control methods in a real environment
