MARINE SYSTEM FOR MOTION OF FLUID MEDIUM (VERSIONS) Russian patent published in 1999 - IPC

FIELD: marine systems for motion of fluid medium. SUBSTANCE: marine system for motion of fluid medium includes riser whose upper end is articulated with turret on board and lower end is secured to sea bottom by means of anchor chains; it includes hoses; each hose extends from base on sea bottom to turret on board ship, thus excluding complex hose assembly for passing fluid medium across universal joint connecting the riser with turret. Hydraulic connected near lower portion of turret which is located far away from universal joint is connected with hose which extends over winding trajectory from hydraulic joint downward to sea bottom. Considerable length of hose enables it to be bent without excessive tension in case of drift of ship when it gets in contact with riser. Ring-shaped holder located around axis of turret and riser is connected with hose. EFFECT: simplified construction; enhanced reliability. 8 cl, 8 dwg
