Abstract
Tendon segments are fabricated on a laybarge, then temporarily stored on seabottom. When a tension leg platform is moored, two tow vessels pick up one end each of the finished tendon and tow it to deep water, with the tendon in a catenary shape. Upon arrival in deep water, one end of the tendon is released and allowed to free fall to its uprighted position. A special work boat then transfers the tendon to the tension leg platform for final installation.
