A geostationary anchoring and riser arrangement in a vessel comprises a rotating body (11), which is mounted in a vertical shaft (6) in the vessel (1) by axial and radial annular bearings (31, 32). Above the upper axial and radial bearing (31, 32) is mounted a dynamic primary seal (35), thereby establishing a dry space above the bearings, in the shaft (6). Under the bearing is mounted a secondary seal (41). A fluid manifold (28) is placed in the dry shaft space.
