Description

Technical Field

[0001] This utility model relates to the field of oil extraction technology, specifically to the deck layout structure of an offshore oil extraction platform. Background Technology

[0002] Offshore oil exploration platforms include jacket platforms, a common type of fixed platform. It mainly consists of a jacket and a superdeck structure. The jacket is a spatial frame structure welded from numerous steel pipes and fixed to the seabed by piling. The pile legs typically extend tens of meters into the seabed, providing stable support for the platform, while the superdeck structure supports various oil exploration and production equipment.

[0003] The existing deck layout of oil production platforms still has the following problems when in use: the deck space layout of some platforms is not compact and reasonable enough, resulting in excessively large or small distances between equipment and facilities, which affects the space utilization rate and the convenience of personnel operation. For example, some small platforms have narrow passages between areas due to a lack of overall planning when arranging wellhead equipment, production processing equipment and storage facilities, which is not conducive to equipment maintenance and personnel passage.
