Abstract
The utility model discloses a workover rig slide roof beam flexible connection structure between marine fixed platform, the slide roof beam of two platform butt joints department adopt three web box roof beams be equipped with swing joint section collet bottom the abutting end of three web box roof beams be equipped with slide roof beam swing joint section on the swing joint section collet, slide roof beam swing joint section and two three web box roof beams pass through the bolt and connect respectively. The utility model discloses can make the butt joint of two platform slide roof beams once successful, can avoid marine secondary transformation construction to can effectively solve and transmit each other and cause the problem of destruction with two platform differences projected life to the structure that links to each other because of nonconformity, load appear subsiding in two platforms in the use, reduce the totality investment of engineering project, and help fixed platform's safety in production.
Description
Technical field
The utility model relates to the syndeton between fixed offshore platform, particularly relates to two fixed offshore platforms and shares workover rig, the movable connection structure of two platform slipway beam joints.
Background technology
In recent years, rely on the newly-built two leg external platform hangings of built fixed offshore platform and realize drilling and repairing machine share way be widely applied at Bohai Offshore, effectively can reduce the engineering construction investment of oil gas field.The large space platforms such as along with the continuous intensification be familiar with oil reservoir, plug-in two leg platforms often can not meet the needs of production dilatation, newly-built four legs (and above leg) become the active demand of field produces.In order to Control Engineering investment, the drilling and repairing machine of existing platform is effectively utilized, need workover rig slipway beam syndeton between research independent platform.In the past, when newly-built platform is in place and built platform uncontrollable exist left and right, height dislocation, offshore construction need be carried out transform two platform slipway beam dependency structures, connect, two platform workover rig slide rails be adjusted, to meet the needs of workover rig slippage between two platforms simultaneously.In the Long-Time Service process of newly-built offshore platform and built offshore platform, the pile foundation sedimentation of two platforms is different, load transmits impact mutually, the Platform Designing life-span is different, also the workover rig slippage affected between two platforms and platform is kept the safety in production.
Summary of the invention
The utility model provides workover rig slipway beam movable connection structure between a kind of fixed offshore platform for solving in known technology the technical problem that exists, this structure can make two platform slipway beam docking once successes, marine secondary rebuilding construction can be avoided, and can effectively solve because two platforms in use occur that sedimentation is inconsistent, load is transmitted and the two Platform Designing life-span different problems damaged connected structure mutually.
The technical scheme that the utility model is taked for the technical problem existed in solution known technology is: workover rig slipway beam movable connection structure between a kind of fixed offshore platform, the slipway beam of two platform joints adopts three web box beam, be provided with bottom the butt end of described three web box beam and be flexibly connected section collet, described flexible connection section collet is provided with slipway beam and is flexibly connected section, described slipway beam is flexibly connected section and is connected respectively by bolt with two described three web box beam.
Described flexible connection section collet is provided with leveling backing plate.
The advantage that the utility model has and good effect are: adopt three web box beam as fixed platform workover rig slipway beam at two platform joints, for workover rig slide rail reserves adjustable range so that slide rail docking; The slipway beam making suitability is at sea flexibly connected section, for completing the docking of two platform slipway beams, can avoid the secondary rebuilding construction of platform upper chunk, workover rig slide rail, and can guarantee that the workover rig slippage of two platforms is shared.Two independently adopt movable connection structure between offshore platform, can also effectively solve because the sedimentation in Long-Time Service process of two ocean platforms is inconsistent, load is transmitted and the platform different problem damaged connected structure projected life mutually.In sum, the utility model can be installed according to the misalignment of two platform upper chunks and be flexibly connected section collet and slipway beam flexible connection section, make the workover rig slipway beam docking once success of two platforms, reduce the overall investment of object of construction production, and contribute to the safety in production of fixed offshore platform.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of three web box beam of the present utility model and workover rig slide rail fixed thereon.
In figure: 1, three web box beam; 2, section collet is flexibly connected; 3, slipway beam is flexibly connected section; 4, workover rig slide rail.
Detailed description of the invention
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 and Fig. 2, workover rig slipway beam movable connection structure between a kind of fixed offshore platform, the slipway beam of two platform joints adopts three web box beam 1, be provided with bottom the butt end of described three web box beam 1 and be flexibly connected section collet 2, described flexible connection section collet 2 is provided with slipway beam and is flexibly connected section 3, described slipway beam is flexibly connected section 3 and is connected respectively by bolt with two described three web box beam 1.
Adopt three web box beam 1 as fixed platform workover rig slipway beam at two platform joints, can adjust the horizontal level of the workover rig slide rail 4 be located thereon; Be flexibly connected section collet 2 and can carry out Attention problems according to the dislocation of two platform vertical direction, to guarantee that two supporting surfaces being flexibly connected section collet 2 are in same level; Slipway beam is flexibly connected section 3 and at sea makes according to the misalignment of two platforms, with bolts with three web box beam 1 of two platforms.When workover rig does not carry out the slippage operation between two platforms, remove the connection that slipway beam is flexibly connected section 3 and a platform, keep slipway beam to be flexibly connected the connection of section 3 and another platform, can avoid that two platform sedimentations are inconsistent, load is mutually transmitted and damaged connected structure.After the situation that two platform sedimentations are inconsistent occurs, leveling backing plate can be increased on the flexible connection section collet 2 that position is lower, to ensure that two supporting surfaces being flexibly connected section collet 2 are in same level.
Although be described preferred embodiment of the present utility model by reference to the accompanying drawings above; but the utility model is not limited to above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; do not departing under the ambit that the utility model aim and claim protect, can also make a lot of form, these all belong within protection domain of the present utility model.
