Abstract

The invention provides a movable pushing device for sliding launch of a large jacket. The movable pushing device is provided with a plurality of hydraulic jacks; the plurality of hydraulic jacks are respectively arranged on a plurality of slide rails; the front part and the rear part of each hydraulic jack are respectively provided with a fixing unit; and a pushing slide block is arranged in front of each fixing unit of the front part of each hydraulic jack. The pushing device can be flexibly and conveniently operated and can provide balance pushing forces; small space is occupied during construction, and the acting force can be accurately controlled, so that the occurrences of accidents is reduced and time and cost for installing offshore large modules are reduced; and on the premise of guaranteeing safety and reliability, the construction of an offshore oil platform and the construction progress of a project are accelerated and the project quality is improved.

Description

technical field

[0001] The invention relates to a jacking device, in particular to a mobile jacking device for slipping and launching a large jacket, belonging to the field of offshore oil engineering. Background technique

[0002] In offshore oil development projects, various platforms such as oil production platforms, living platforms, and central processing platforms need to be built offshore. The platform generally mainly includes: offshore engineering blocks, underwater support structures—jackets, single points, and other offshore engineering structures. These marine engineering structures are generally prefabricated on land first, and then transported to sea for installation.

[0003] The installation of large jackets is a very complicated project. In the process of shipping large jackets, it is necessary to provide the jacking force for the sliding and launching of large jackets weighing tens of thousands of tons to control the large jackets. The rack slides into th...
