Abstract

PURPOSE: To tow and to easily install an ice barrier prefabricated in a factory by comprising a box-shaped barge provided with a roof-shaped structure thereon consisting of a plurality of bars of plates and a mechanism for charging and discharging the barge with water.
CONSTITUTION: A rig 1 is moored by a mooring arrangment 2, a plurality of ice barriers 3 are disposed around the rig to protect the rig 1 from drift ice. The ice barrier 3 comprises a box-shaped barge and an inclined structure 4 consisting of bars. The box-shaped barge is formed in a hollow box and is capable of being charged and discharged with ballast water. When the barge is installed, the barge is imersed in the sea and the roof-shaped structure 4 projects above the sea, therfore, blocks of drift ice run on the ice barrier 3. The ice barrier 3 is fabricated on land and is towed to the site by a ship to facilitate installation.
