Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings:

[0030] see Figure 1-Figure 5 , an embodiment of the method for disposing an abandoned structure of an offshore oil platform and laying out an artificial reef according to the present invention, the abandoned structure of an offshore oil platform includes a decommissioned platform 2 and its ancillary equipment and facilities, and the decommissioned platform 2 is used as an artificial fish reef The central frame of the reef is equipped with unit reefs 3 formed by single reefs, abandoned concrete structures, and scrapped ships on its periphery, forming reef groups 1, and at least two reef groups 1 rebuilt from decommissioned platforms 2 along each The direction of trestle bridges between independent decommissioned platforms constitutes fish reef zone 4.

[0031] The above-mentioned fish reefs include tubular reinforced concrete fish reefs (see Figure 4 ) and...

Abstract

The invention provides a method for distribution of offshore oil platform abandoned structures and laying of artificial reefs. The method is characterized in that each offshore oil platform abandoned structure comprises an abandoned platform and auxiliary equipment and facilities thereof, the abandoned platform is used as a central frame for the artificial reefs, reef units which are disposed around the central frame and composed of single reefs, abandoned concrete structures and discarded ships form a reef group, and at least two reef groups built with the abandoned platforms form a reef belt along trestles between the respective independent platforms. The plurality of small-sized reef belts built with the abandoned platforms form a large-sized reef belt in a centralized oil production area. Each single reef is composed a tubular reinforced concrete reef and cubic-framed reinforced concrete reefs by stacking. By the method, economic cost, environmental cost and energy consumption in treatment of offshore oil platforms are lowered, the fishery enhancement function is given to play more effectively.

Description

technical field [0001] The invention belongs to the technical field of artificial breeding and release of marine products and marine environment ecological restoration, and relates to an artificial fish reef configuration and a method for laying it out, in particular to a method for configuring and laying out artificial fish reefs by using abandoned structures of offshore oil platforms. Background technique [0002] With the continuous increase of people's demand for sea cucumbers, abalone and other seafood, the amount of natural seafood resources has decreased significantly. The existing technology uses the following two methods to improve the contradiction between supply and demand of seafood: one is large-scale artificial breeding, but due to artificial The aquaculture itself is seriously polluted, and the frequent occurrence of diseases caused by high-density aquaculture degrades the quality of aquaculture seafood, and there are food safety problems, which restrict the de...
