Claim 0:
1. A system for restriction of hawser movement in a tandem mooring and loading system comprising:
a first floating structure being spread moored, and;
a second floating structure, and;
a tandem mooring arrangement between the first floating structure and the second floating structure comprising:
at least one hawser connected in a first end to a hawser connection arrangement having a stationary attachment point on the first floating structure, and in a second end connected to a hawser connection point on the second floating structure, and;
a loading arrangement
wherein the system comprises a hawser guide arrangement, wherein the hawser guide arrangement comprises:
at least two guide structures situated on either side of the hawser connection arrangement and on an outside of an aft starboard side and an aft port side of a vessel hull on the first floating structure, for allowing a weather-vanning sector larger than 180 degrees by hindering the at least one hawser from crossing over a deck portion of the first floating structure when the second floating structure weathervanes relative to the first floating structure
wherein the at least two guide structures each have a vertical height extending from a bottom end below the hawser connection arrangement to a top end above the hawser connection arrangement, wherein a minimum height of the at least two guide structures is adapted to a vertical working range of the at least one hawser at a location of the at least two guide structures.
