METHOD TO DEVELOP FLUID HYDROCARBON FIELD IN SHALLOW FREEZING WATER AREA AND TRAVELING PLATFORM Russian patent published in 2008 - IPC E02B17/00 

FIELD: hydraulic construction, particularly to construct offshore oil, gas and gas condensate production platforms arranged in northern river mouths and in shallow freezing sea shelf.

SUBSTANCE: method involves arranging at least one traveling platform in point of well cluster drilling. Traveling platform has cut made in bottom plate of support block. Head module with composite manifold is provided with additional bottom plate and is arranged in lower part of support block so that it may be separated and moved within said bottom plate cut. Technological modules are also arranged in lower part of support block so that at least one module may be separated from support block and slide inside it. After traveling platform installation in drilling site head module with composite manifold on supplementary bottom plate is installed on bottom within the cut of bottom support plate, wherein drilling module is arranged over head module with composite manifold location inside support block at height of not less than sea level. Interior of detachable vessel included in technological module is communicated with each well head interior through hydraulic line provided with valves.

EFFECT: increased speed of deposit putting into operation due to provision of all-the-year-round deposit drilling and platform operation.
