Movable offshore self-mounting dry type work environment construction process

Abstract

The invention discloses a movable offshore self-mounting dry type work environment construction process. The movable offshore self-mounting dry type work environment construction process is characterized in that a main box body and an auxiliary float box are connected and fixed, and the main box body and the auxiliary float box which are assembled together are consigned to the construction point through a barge; three points are selected from the main box body and the auxiliary float box which are connected together to form a regular triangle structure, and triangular barge pulling and positioning can be achieved; through a lifting system, a ballast water tank body is lifted, and a cylinder body penetrates into a seabed; a steel pile is driven into a fixed pile guide groove, and the platform whole stability is improved; and during pulling, through a spraying flushing device, absorbing force is reduced, and through buoyancy of the float box, a work cylinder can be automatically pulled out, through the barge, the float box can be dragged to the next construction position, and operation is carried out in sequence until all construction points are finished. Compared with the prior art,the process has the beneficial effects that the construction process is stable and reliable, cost is low, through the construction process, the dry type environment can be provided for seabed work for a worker, and recycling of a whole system is achieved.

Description

technical field [0001] The invention relates to an offshore construction technique, in particular to a mobile offshore self-installation dry-type construction technique. Background technique [0002] A drilling platform is an offshore structure primarily used for drilling wells. Drilling, power, communication, navigation and other equipment installed on the platform, as well as safety and lifesaving and personnel living facilities, are indispensable means for offshore oil and gas exploration and development. [0003] At present, in the process of offshore drilling and production, construction personnel generally need to use offshore platforms to carry out corresponding construction operations, instead of directly reaching the sediment surface of the seabed for operations. Although equipment can also be used to dive to achieve the purpose of seabed construction, but the The difficulty of construction is also usually higher. [0004] Therefore, in view of the above problems,...

Problems solved by technology

[0003] At present, in the process of offshore drilling and production, construction personnel generally need to use offshore platforms to carry out corresponding construction operations, instead of directly reaching the sediment surface of the seabed for operations. Although equipment can also be used to dive to achieve the purpose of seabed construction, but the The difficulty of construction is usually higher

[0004] Therefore, in view of the above problems, it is necessary to propose a mobile offshore self-installation dry working environment construction technology to solve the problem that operators are more difficult to construct on the seabed during the oil extraction process
