COMPLEX FOR DEVELOPMENT OF SUB-SEA DEPOSITS OF MINERALS Russian patent published in 2009 - IPC B63B35/44 E21B43/01 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to engineering equipment for development from wells of such natural resources of World Ocean as oil and gas as well as other minerals form gravel sub-sea deposits. The complex for development of sub-sea deposits of minerals consists of an assembly frame either on a mother ship in the open sea, on an island or on shore; the frame is designed for fabrication, test and launching pressure tight chambers with equipment installed therein. Pressure tight casings with pipelines and casings with power and control cables are connected with chambers. Also the head part of the complex is transferred in submerged position from the site of assembly frame to the specified coordinates of the sea bottom by means of alternate switching on maneuvering devices of pontoon blocks; the length of transport system of the complex is being gradually increased by means of addition of the next sections inside the assembly frame. To maintain the course of complex traveling not less, than two submarines are used which are continuously coupled with the head part of the complex.

EFFECT: increased reliability of complex operation.
