A hawser system between a tension leg platform (TLP) and another vessel employs two lines, oriented in a V-shape, to restrict the vertical motion of a hawser near the bow of the other vessel which may be a semi-submersible tender assisted drilling vessel (TAD). Drilling operations may be performed from the TLP while the semi-submersible provides the supporting services for the drilling operation, e.g. drilling fluid and drill pipe storage. The restricted vertical motion of the hawsers significantly reduces the possibility of the hawsers contacting each other. A hawser system according to the invention couples the semi-submersible TAD vessel to the TLP and may be implemented without passing the hawsers through sheaves.
