FIELD: oil product storage facilities.
SUBSTANCE: tank comprises body with bottom, floating lid 4 and device to scour bottom sediments. The device comprises elastic pressure pipeline system 7 arranged on floating roof 4. Pipeline system 7 is linked with pump 9 through high-pressure hose 8. The pump 9 is built in supply oil pipeline 10. Floating roof 4 has hatches 11 for passing elastic polymeric pipes 12. Polymeric pipes are connected to floating roof by flanges 13. Upper ends of the polymeric pipes 12 are connected to pipeline system 7. Lower ends thereof have scouring nozzles 14. Polymeric pipes 12 are also secured to floating roof by means of synthetic ropes at angles providing discharge of scoring jets around a circle to cover the whole bottom surface and to prevent dead zone formation.
