METHOD OF ARRANGEMENT OF ARCTIC TECHNOLOGICAL COMPLEX Russian patent published in 2006 - IPC E02B17/00 

FIELD: outfit of underwater mineral deposits, mainly liquid and gaseous under various conditions of sea bottom ground.

SUBSTANCE: arrangement of arctic technological complex includes erection of central and peripheral offshore platforms and coastal technological base which are interconnected by main-type piping system. Base of each offshore platform is made in form of stationary module which is mounted on bottom bearing plate and is rigidly connected with ground by means of tension anchor connections. Height of stationary module of offshore platform provides passage of ice cover or icebergs with no contact. Use is made of at least one detachable module which may be coupled in turn with stationary modules; it is made in form of semi-submersible platform provided with ballast reservoirs and technological equipment used for drilling, erection, adjustment, alignment and repair of technological wells; at least one detachable module is provided with compressor station for building-up required pressure in mains.

EFFECT: enhanced reliability and economical efficiency under arctic conditions.
