FLOATING SUPPORT OR VESSEL EQUIPPED WITH DEVICE FOR DETECTION OF LIQUID BODY FREE SURFACE MOTION Russian patent published in 2014 - IPC B63B25/16 B63B39/00 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding and concerns vessels or floating platforms intended for liquid transportation and storing, specifically cryogenic transportation of compressed natural gas or other gases in liquefied state. The invention claims vessel or floating platform (1) for transportation and storing of liquid (3) representing compressed gas, preferably methane, ethylene, propan or butane, cooled in at least one large tank (2), preferably cylindrical with polygonal cross-section, fitted with heat insulation (2a) and having large dimensions, herewith, at least its minimum size in horizontal plane, specifically its width, exceeds 20 m, and preferably is 25 to 50 m, and volume exceeds 10000 m³, herewith, the mentioned large tank (2) is installed inside vessel hull (4) on load carrying structure (11). Vessel or floating platform contains multiple devices for detection of liquid disturbance inside the mentioned large tank (the mentioned large tanks). Such devices are called "beacon lights" (5, 5-1, 5-2) and contain: a) vibration sensor representing vibration accelerometer, b) electronic computing module, containing microprocessor and built-in memory and made capable to process a signal measured by the mentioned vibration sensor (5a) in order to at least remove vessel own background noise, c) means for signal transmission after its processing by the mentioned electronic computing module to central module or controller (6) preferably installed on bridge.

EFFECT: higher safety of liquid transportation and storing on vessel or floating platform.
