Abstract
The utility model relates to an integrated drainage device. The integrated drainage device is characterized in that the device comprises a horizontal drainage pipe arranged on the bottom surface of the ship stern part on a platform and two vertical drainage pipes which are close to the horizontal drainage pipe and are positioned on the inner sides of the two upright posts of the platform, the top parts of the two vertical drainage pipes have a shape of a tunnel, and bottom parts of the two vertical drainage pipes are arranged underwater; and the pipes for draining water out of the side of a ship in the systems of the platform are connected with the near horizontal drainage pipe or the vertical drainage pipe in the welding way. The integrated drainage device not only beautifies the overall appearance of the platform and meets various drainage requirements, but also ensures the structural strength and the water tightness of the platform. Meanwhile, the device is helpful for drainage monitoring so as to protect ocean environment.
Description
Technical field
The utility model relates to a kind of freeing arrangement, particularly about a kind of be the integrated freeing arrangement of " marine oil 981 " deep water semi-submersible drilling platform design-calculated.
Background technology
In half latent drilling platform design, a lot of systems all need the fluid of its generation is discharged outboard, as central cooling water system, ballast pumping system, bilge piping system, main frame cooling water system, ash water system and Heisui River system etc.In traditional design, normally row's side of a ship external pipeline of each system is directly drawn by the drain gutter of offering on the ship hull plate nearby.Because each system residing position difference on drilling platform, therefore this traditional design can cause some drain gutter to be held on upper hull, and some drain gutter is opened on column.Because the upper hull of semi-submersible drilling unit all is the relative zone of concentrating of stress with column, if perforate too much will certainly influence the structural strength of whole hull, also can influence the watertight integrity of hull.In addition, discharge the paint of the direct erosion hull of fluid meeting of outboard, thereby influence the life-span of hull.Simultaneously, if a lot of fluid is arranged from upper hull or column, not only influence the overall image of drilling platform, and influence the workman in the operation of drilling platform bottom.
At present, what " marine oil 981 " deep water semi-submersible drilling platform during China National Offshore Oil Corporation is designing and building faced is comparatively severe sea condition environment of China South Sea, local wind speed reaches 54 meter per seconds sometimes, can reach 56.9 meter per seconds when extreme, 13.7 meters of Yi Bogaoda are arranged, flow velocity reaches 2.2 meters, and therefore traditional design can not be satisfied the structural strength and the watertight integrity of hull, needing to demand urgently a kind of later-model freeing arrangement to solve the problems referred to above.
Summary of the invention
At the problems referred to above, the purpose of this utility model provides a kind of integrated freeing arrangement that need not to offer drain gutter on the hull of semi-submersible drilling unit.
For achieving the above object, the utility model is taked following technical scheme: a kind of integrated freeing arrangement, it is characterized in that: it comprises the horizontal drain pipe and the two vertical drain hoses that close on described horizontal drain pipe and be positioned at platform two column inboards that are arranged on platform upper hull stern bottom surface, the top of two described vertical drain hoses is infundibulate, and the bottom of two described vertical drain hoses causes underwater; Row's side of a ship external pipeline on the platform in each system connects described horizontal drain pipe or vertical drain hose nearby by the mode of welding.
The utility model is owing to take above technical scheme, it has the following advantages: the utility model connects level or vertical drain hose with the row's side of a ship external pipeline in each system nearby by the mode of welding, thereby need not on the hull of semi-submersible drilling unit, to offer drain gutter, flat-bed overall image both attractive in appearance, satisfy various emission requests, guaranteed flat-bed structural strength and water tightness again.Help monitoring simultaneously, protected marine environment discharging.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As shown in Figure 1, the utility model comprises the horizontal drain pipe 2 and the two vertical drain hoses 4 that close on horizontal drain pipe 2 and be positioned at platform two columns 3 inboards that are arranged on semi-submersible drilling unit upper hull 1 stern bottom surface, the top of two vertical drain hoses 4 is infundibulate, to catch the water that flows out by horizontal drain pipe 2 two ends, the bottom of two vertical drain hoses 4 causes underwater, just water can be entered marine.Then the row's side of a ship external pipeline in each system on the platform is connected horizontal drain pipe 2 or vertical drain hose 4 nearby by the mode of welding.Can't see discharge port from the outside like this, flat-bed overall image both attractive in appearance has satisfied various emission requests, has guaranteed flat-bed structural strength and water tightness again.Help monitoring simultaneously, protected marine environment discharging.
The utility model only describes with the foregoing description; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model; all improvement and equivalents of individual component being carried out according to the utility model principle all should not got rid of outside protection domain of the present utility model.
