DRILL TARGET DAMAGE PROTECTION DEVICE FOR MOVEMENT OF ICE FLOES

摘要

FIELD: agriculture.SUBSTANCE: device is presented in the form of a protective barrier mounted on a bed along the perimeter of a drill target and supported by piles on the bed. The piles are designed in the form of a reinforced-concrete cone ballast anchor. The piles are connected in their upper part with safety guards; the latter are connected with a neutral buoyancy floatation device on its end surfaces. In their middle, the safety guards are connected to each other by means of locking elements; the upper parts of the safety guards are connected to each other by means of stopper elements. In its lower part, the floatation device is provided with a stabilisation device presented in the form of a pyramid-shaped metal frame.EFFECT: more reliable protection of the off-shore targets used for economic activities against the impact of ice features.1 dwg
