Claims

[Scope of utility model registration request]

A plurality of pillars are established on the seabed so as to surround an offshore oil storage tank, and a floating oil embankment is installed between the upper parts of the two adjacent pillars, and a sealing member is installed at both ends of the pillar to protrude laterally and extend vertically. When it comes into contact with the opposing guide surface of the pillar guide, 1
By inserting multiple guide grooves protruding from both ends into the guide grooves of the pillars, each floating oil embankment can be raised and lowered relative to each pillar in a liquid-tight manner according to the tide level. A system designed to contain oil leaking from an offshore oil storage tank inside a floating oil embankment, characterized in that a water-resistant, oil-resistant, and heat-resistant elastic body is provided on the guide surface of the guide roller and/or guide groove. A floating oil embankment for offshore oil storage tanks.
