Abstract: A mooring assembly for a vessel comprises a moonpool having a casing, a turret mounted in a moonpool for a rotation by upper and lower bearing assemblies. The lower bearing assembly comprises a stiff inner bearing ring attached to a lower part of the turret, an outer bearing ring attached to a casing of the moonpool and a number of circumferentially spaced bearing blocks positioned between the inner and outer bearing rings. A mounting assembly maintains a substantially fixed position of the bearing blocks relative to the outer bearing ring but allows the bearing blocks to assume a position where the load transfer between the bearing blocks and outer bearing ring occurs with a minimum of stress concentrations within the outer bearing ring and wherein the larger part of the load transfer occurs directly between the bearing blocks and outer bearing ring without being directed through the mounting assembly.

Abstract: An assembly of chain stopper and chain includes a housing, a vertically extending chain channel defined in the housing in which a chain is received and guided and two chain lockers positioned at opposite sides of the chain channel. Each chain locker pivots on a chain locker pivot axis between an inwardly rotated position engaging the chain and preventing a downward shift of the chain, and an outwardly rotated position allowing an upward shift of the chain. Each chain locker is biased towards its inwardly rotated position. Each chain locker pivot axis as a result of forces transmitted by the chain on the respective chain locker is displaceable from its original position to a stable second position in which the respective chain locker, in its inwardly rotated position, is not able to engage the chain in a manner for preventing a downward shift of the chain in the chain channel.
