Part of: Mechanics Computing in 1990's and Beyond


A model is presented for investigating the overall quasi-static behavior of tethers, the anchoring elements for a Tension Leg Platform, TLP. Effects of tether weight and curvature, and current drag loads for deepwater TLP's are examined. Design formulas are presented for estimating offset, set down, and the tether tension variation resulting from these motions.
