SEA PLATFORM FOR SUPPORTING SELF-RAISING FACILITIES Russian patent published in 1999 - IPC

FIELD: construction engineering. SUBSTANCE: sea platform is used in hydraulic engineering structures erected in water area of seas. Sea platform is mainly intended for supporting self-raising drilling rigs, oil and gas producing facilities, and sea bases used in prospecting and producing oil and gas in sea medium. Sea platform is made in the form of ground base having three or more towers or columns. Columns are used to directly support posts of self-raising drilling rig or producing facility. Aforesaid arrangement of sea platform can be used for supporting sea base which in its turn supports drilling guide columns and decking and other structures which are used for carrying oil and gas producing facilities. Power plants can be also installed here. Sea platform can be installed in various sites of well drilling without any serious modifications so as to adapt it to real local conditions. Aforesaid embodiment of sea platforms widens is functional potentialities. EFFECT: higher efficiency. 7 cl, 9 dwg
