An anchoring system includes a vessel and one or more anchor lines extending from a first anchor to a pulling device on the vessel and from there on to a second anchor. The anchor line may extend transversely to the length direction of the vessel, or may extend parallel to the length direction of the vessel, offset from the longitudinal or transverse centre-lines. The anchoring system provides an active semi-weathervaing capability whereby heave and roll motions may be significantly reduced. Accurate station keeping maybe achieved with a relatively small number of pulling devices, the pulling force of which can be relatively small.
