Method of towing and installing a pipe

Priority Date: 2002-01-25

According to the present invention, a solution is provided whereby rather than directly towing a pipe ( 30 ) from a tug ( 11 ), a cable ( 23 ) is suspended between two surface vessels ( 10, 11 ), and it is from this cable ( 23 ) that the pipe ( 30 ) itself is suspended at a plurality of points. By means of this arrangement, stress and fatigue is absorbed by the cable ( 23 ) rather than the pipe ( 30 ), such that the pipe ( 30 ) arrives at its installation point with a correspondingly smaller loss in fatigue life.
