A deck drop system

Abstract

The invention relates to a deck water drainage system. The deck water drainage system comprises a deck body and water drainage subsystems symmetrically arranged on the deck body. Each water drainage subsystem comprises a plurality of water drainage holes formed in the upper end of the deck body, a plurality of branch pipes connected with the water drainage holes, a header pipe connected with the ends of the sides, far away from the water drainage holes, of the multiple branch pipes, a three-way valve control system arranged at the end of the header pipe and a pair of waste oily water bins. The deck water drainage system has the advantages that the three-way valve control system is added to the deck water drainage system based on the prior art and used for carrying out sampling analysis on the oil concentration in media, if it is detected that the oil content in the media is qualified, the media are directly discharged into seawater, and if not, the media are discharged into the waste oily water bins; and according to the deck water drainage system, the designed hold capacity of the waste oily water bins can be reduced, space and cost are reduced, the handling capacity of an oil-water separator does not need to be increased, and the equipment purchasing cost is reduced.

Description

technical field [0001] The invention relates to a deck falling into water system, which belongs to the technical field of large-scale offshore equipment control. Background technique [0002] Because the drilling platform is far away from the land and the cost is high, the space layout is extremely valuable; however, due to the particularity of the drilling platform, the code has many requirements for the design of the drilling platform. In order to meet these requirements, the drilling platform needs to list some space separately for placement equipment or other measures to meet the specification requirements, so how to balance the space setting and make full use of the space of the drilling platform on the basis of meeting the specification requirements is particularly important. [0003] However, the main deck of the drilling platform is equipped with pumps, generators and other equipment, and may also be equipped with drilling equipment in the later stage. During the ope...

[0004] The traditional treatment method is to collect all the leakage branch pipes to the main pipe, and the main pipe is connected to the slop oil water tank, and then the oil water separator is used to treat the slop oil water, and the treated water is discharged. If this design is followed, the drilling platform must be equipped with a Large-capacity slop oil and water tanks also need to increase the treatment displacement of the original water separator, which increases the space of the drilling platform and increases the manufacturing cost of the equipment. Deck water fall system, after searching, no technical solution identical or similar to the present invention was found
