Offshore engineering ship-borne platform surveying equipment retracting and releasing device and retracting and releasing method

Abstract

The invention discloses an offshore engineering ship-borne platform surveying equipment retracting and releasing device and a retracting and releasing method. The device comprises a door hanging module, a bracket module and a swing frame, and the door hanging module is integrally erected on a cantilever side of a ship-borne platform, and swings between the inside and the outside of a ship board; the bracket module is connected to the platform, perpendicular to the outside of the platform and rotatable relative to the platform by at least 90 degrees; the swing frame is disposed on the door hanging module. Through the overall swing of the door hanging module and the flipping of the bracket module, surveying equipment suspended on the ship-borne platform enters the water and exits, which is not restricted by the size of wind and waves, and effectively solves the problems existing in the prior art. The device has compact overall structure and small occupied platform space, the hanging process is not affected by sea wave conditions, and the device can be used for retracting and releasing of the surveying equipment for the offshore engineering ship-borne platform.

Description

technical field [0001] The invention relates to offshore engineering survey equipment technology, in particular to the hoisting technology for geotechnical engineering ship-borne platform survey equipment. Background technique [0002] Offshore geotechnical engineering survey mainly adopts drilling sampling or in-situ testing, and marine exploration equipment is required, such as seabed static penetration sounding machine, intelligent drilling parameter instrument, marine drilling rig, submarine cone / drilling integrated machine, etc. These equipments are usually transported to the working site by means of workboats, anchored and positioned, and then hoisted to the seabed by the retractable mechanism to start the survey. After the operation is completed, it will be recovered by the retracting mechanism to the ship-borne platform, and the transition will be carried out. This process will be repeated until the survey of the entire sea area is completed. Existing offshore engin...

Problems solved by technology

However, this system requires a large platform space and a sufficiently high gantry. It needs to be equipped with auxiliary equipment such as buffer damping, azimuth adjustment, and wave compensation. It should have a low drilling tower (hanger) height and strong portability for offshore engineering ship-borne platform surveys. , convenient installation, low construction cost, etc.
