A loading arrangement includes a riser that extends from a subsea structure
to a coupling element for coupling the riser to a vessel. The coupling
element includes a buoy body which is connected to a retention member via
a flexible connection part. The retention member, such as a submerged
buoy, is attached to anchor lines which at or near their end parts are
provided with buoy. The connection part, which can be a cable or a frame
structure has a relatively high tensile strength to anchor the vessel to
the sea bed and to prevent drift of the vessel when tension is exerted on
the connection part and the anchor line.
