MOUNTING BASE RESTING ON SEABED AND METHOD FOR INSTALLATION THEREOF Russian patent published in 2020 - IPC E02B17/00 E02D27/20 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to a method of installing a mounting base configured to rest on the seabed, preferably and at least partially above the inclined sea bottom and to the stationary offshore platform in shallow water, preferably for storage, as well as loading or unloading hydrocarbons, such as LNG (liquefied natural gas), oil or gas, containing floating and detachable mounting base, adapted for support on sea bottom. Main structure comprises floating and detachable mounting base (10) adapted to rest on sea bed (30), wherein the mounting base comprises support structure (11) preferably provided with an upwardly projecting wall structure (22) lying along at least a portion of the perimeter of support structure (11), wherein mounting base (10) is preferably also provided with hole (23) in wall structure (22) to provide floating module with possibility of docking to mounting base (10) and is supported by it. Mounting base (10) is provided with support points (24) configured to receive ends of pre-installed vertical piles (14) for at least temporary support of supporting structure (11) during pile installation operation for permanent installation of piles into seabed (30) for mounting base structure (10). Said publication also relates to method of fixation of mounting base structure by piles on sea bottom (30) or above it.

EFFECT: mounting base resting on seabed and method of its installation are disclosed.
