A crossload bearing/upper flex assembly at the top of each tension leg is

located in the individual mooring tunnel area. This flex assembly allows angular

movement of the tension leg below the TLP and also takes up any side loads

imposed by TLP movements.

Along with the fact that foundations and risers comprise only a small

percentage of total costs, the extensive use of standard equipment and techniques
gives the tension-leg platform the ability to operate in water depths well beyond

those possible with existing technology. The significant cost advantage is apparent.
Cost reductions may also accrue by reducing the number of tubulars required for

each well. The TLP concept may well provide economical feasibility and impetus
for development of deep-water marginal fields.
