Problems solved by technology

The problem is: Due to the increasing construction of marine engineering products, the demand for lifting devices and locking devices is also increasing
Affected by various factors such as the supplier's production capacity and product quality, during the construction of the existing berth, after the main body of the platform is completed, the lifting device and locking device may be in a state that has not arrived or has not been installed or has not been debugged. In the case of some problems caused by the state or equipment, the smooth launch of the platform under construction cannot be guaranteed, which invisibly occupies the resources of the berth and increases the construction period of the platform
These effects increase the cost of marine engineering products

Embodiment Construction

[0021] The invention discloses a method for sealing the spud legs and spud boots when the platform is launched into the water. The method mainly adopts locking tooling and connecting channel steel to respectively seal the spud legs and spud boots; a special device is used to seal the spud legs After the legs and spud shoes are jacked up, a method of sealing the legs and the spud shoes when the platform is launched has been researched and designed.

[0022] The specific sealing structure is as Figure 1~3 As shown, it includes four steel plates 1 that mesh with the rack plates of the pile legs and have straight outer contours, two fastening plates 4 with upper and lower inner walls that are in the same arc as the outer skin of the leg chord tube, and the fastening plates 4 are spaced apart and radiate The main force plate 2 arranged in a shape; between the adjacent main force plates 2, and between the main force plate 2 adjacent to the steel plate 1 and the steel plate, an arc-...

Abstract

The invention discloses a pile leg and pile shoe sealing method used when a self-elevating drilling platform enters the water. According to traditional domestic and international methods, when a platform for slipway construction enters the water, pile legs and pile shoes need to be elevated in place and locked after a lifting device and a locking device of the platform are well installed and debugged. According to the method, certain devices, namely a locking tool and a connecting steel channel are adopted for pile leg and pile shoe sealing. The locking tool is composed of three parts, namely a base side sealing pier, an inner side sealing pier and a high-strength bolt. The locking tool is in the shape of a boot and seals racks of pile legs inside the boot tightly. The locking tool is obtained through steel plate welding. In installation, the locking tool is welded to other structures of the platform to lock the pile legs inside through bolts. Pile shoes are sealed though the steel channel and a main ship body of the platform. The tool is simple in structure, safe and reliable. Practical application proves that the method is remarkable in effect.

Description

technical field [0001] The invention relates to the technical field of marine engineering, and more specifically relates to the improvement of sealing when a jack-up drilling platform is launched. Background technique [0002] With the increasing demand for international offshore engineering products, the number of platform construction is increasing, while the supply of lifting devices and locking devices is in a relatively slow growth period, which affects the construction, launching and commissioning of platforms to a certain extent. construction period. Specifically, under the existing technical method, after the construction of the marine engineering product is completed on the berth, the lifting device and the locking device must be installed and debugged, the spud can and the spud legs must be lifted to a certain height, and then launched into the water after being locked. The problem is: due to the increasing construction of marine engineering products, the demand f...
