METHOD STATEMENT drilling vessel to the turret ANCHOR SYSTEM TO HOLD ICE CONDITIONS

摘要

FIELD: mining.;SUBSTANCE: chains with anchors are moved by means of tow cars - anchor bringing machines till their installation point. First, anchor chains are moved under ice with their further lifting onto decks of tow cars - anchor bringing machines by means of towing winches using guiding ropes that are attached to end shackles of anchor chains and moved with remotely piloted underwater vehicles of a torpedo-like shape of a captive type to tow cars - anchor bringing machines. After end clamps of anchor chains are lifted onto decks of tow cars - anchor bringing machines, anchors are attached to them.;EFFECT: safe and effective positioning of a drilling ship under ice conditions.;5 dwg
