Abstract

Bearing arrangement (22) for a turret (4) in a vessel (1) for drilling for, storing and/or extracting oil and/or gas from a geological formation under the sea bed. The vessel is designed, via a turret, to be anchored to the sea bed via anchor lines (7). The friction in the bearing (5) of the turret is of such a magnitude that it causes the rotational resistance of the bearing M turret, with dynamic, high-frequency rotational movements which are less than 2° (amplitude), to be greater than the sum of the yaw moment of motion M r and the spring moment M anchor of the anchor lines, but less than the spring moment M anchor of the anchor lines with low-frequency rotational movements which are greater than 10° (amplitude).
