POSITIONING SYSTEM FOR SHIP, MAINLY SUBMARINE

摘要

FIELD: shipbuilding; pilotage and placing of ships in dock, mainly submarines in shallow waters. ^ SUBSTANCE: proposed ship positioning system includes pontoons at adjustable buoyancy and ship raising unit containing load-bearing members provided with devices for securing them on pontoons. Ship raising unit has at least two load-bearing members made in form of curvilinear beam. At least one curvilinear beam may be mounted on supports by means of quick-release gripping devices of bayonet joint type. Supports are provided with foundations which may be rigidly connected with main hull of ship. Each curvilinear beam has box-type section. At least one curvilinear beam is mounted on two supports symmetrically relative to ship' CL. Each support may be made cylindrical and may be provided with rests onto foundation which is welded to main hull of ship. Each beam may be secured on pontoon by means of turnbuckles fitted with locks. ^ EFFECT: avoidance of damage to submarine hull; facilitated procedure of docking her. ^ 15 cl, 4 dwg
