Abstract

The invention discloses a test method for an active heave compensation crane and belongs to the technical field of hoisting. According to the test method, a motion reference unit is installed on a six-degree-of-freedom test platform, the six-degree-of-freedom test platform is controlled to simulate wave motion, so that a test is conducted on the active heave compensation crane, and whether an active heave compensation function of the active heave compensation crane meets the requirement is judged. The motion reference unit is small in size and weight, so that installation is simple. Meanwhilethe small-size six-degree-of-freedom test platform can also be selected for the test, and test cost is lowered.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a test method for active heave compensation cranes. Background technique [0002] When carrying out deep-sea hoisting operations, a crane is usually installed on the floating platform. The crane is equipped with a winch and a steel wire rope. The winch is connected to the heavy object on the seabed through the wire rope, and the lifting of the heavy object is controlled by the positive and negative rotation of the winch. rise and fall. The floating platform is located on the sea surface, affected by the ocean wind and waves, the crane will move with the floating platform in six degrees of freedom of heave, roll, pitch, sway, surge and yaw, which may cause the suspended objects Collision with the seabed affects the hoisting operation. [0003] In order to prevent the suspended object from colliding with the seabed, cranes with active heave compensation function are often used f...
