A personnel entry and exit system for shallow-depth seabed dry oil production equipment

Abstract

The invention relates to a system for entering and exiting a cabin of a shallow-depth seabed dry oil recovery device. The external structural components of the cabin are vertically suspended on the water surface support components, and power is supplied through the water surface support components. The internal installation of the external structural components of the cabin is used to perform drainage. , mechanical components for water injection, air supply and emergency operation, life support components for providing breathing oxygen, and electronic control components for providing cabin lighting, equipment power supply and signal collection and processing; also includes dry cabin hatch components , when the external structure assembly of the cabin body and the hatch assembly of the dry cabin are docked, the external structure assembly of the cabin body and the hatch assembly of the dry cabin communicate internally to form a vertical passage for personnel to pass through. The present invention can be used for dry-type normal-pressure entry and exit of personnel for maintenance of shallow-depth underwater oil production dry-type tanks, and has no harm to personnel health; the present invention has good economical efficiency and low maintenance cost; the present invention is easy to transport and can be shared by multiple oil wells cover; the present invention has no influence on waterways and military areas, and has a wide range of applications.

Description

technical field [0001] The invention relates to the technical field of personnel entering and exiting cabins of oil production devices, in particular to a system for personnel entering and exiting cabins of shallow-depth seabed dry oil production equipment. Background technique [0002] With the deepening of the development of oilfields in the Bohai Bay, some marginal small oilfields are located in the restricted areas of the Bohai Sea (military areas, waterway areas, etc.), and construction of engineering facilities is not allowed on the sea. Although the conventional wet subsea production system is technically expected to solve the problem of oilfield development in restricted areas, its complex equipment, high technical threshold, and high investment cost have greatly hindered large-scale application and will greatly reduce the economics of oilfield development. efficiency, and most of its equipment is imported from abroad, which cannot meet the requirements of the manage...

Problems solved by technology

Although the conventional wet subsea production system is technically expected to solve the problem of oilfield development in restricted areas, its complex equipment, high technical threshold, and high investment cost have greatly hindered large-scale application and will greatly reduce the economics of oilfield development. efficiency, and most of its equipment is imported from abroad, which cannot meet the requirements of the management of our country's military areas. In the later maintenance, personnel are also required to operate under pressure, which brings great harm to the physical and mental health of personnel.

[0003] The current attempt includes the use of raising the riser. Before entering the dry cabin, the construction ship will install the riser in place, and the maintenance personnel will enter the cabin through the riser. This way of raising the riser requires the cooperation of a large construction ship. And the preparation time is long, which affects the passage of the channel, and the rising riser is greatly affected by the water flow, and the flange structure on the dry tank connected to the bottom of the riser is relatively complicated. This method is inefficient and requires a lot of work. Operability is not strong
