Tension-leg platform

A feature of the design of the tethers is that they have relatively high axial stiffness (low elasticity), such that virtually all vertical motion of the platform is eliminated.

This allows a simpler well completion and gives better control over the production from the oil or gas reservoir, and easier access for downhole intervention operations.

[1] The total area of its living quarters was about 3,500 square metres and accommodated over 100 cabins though only 40 people were necessary to maintain the structure in place.

[5] Blue H Technologies of the Netherlands deployed the world's first floating wind turbine on a tension-leg platform, 21.3 kilometres (13.2 mi) off the coast of Apulia, Italy in December 2007.

[6][7] The prototype was installed in waters 113 metres (371 ft) deep in order to gather test data on wind and sea conditions, and was decommissioned at the end of 2008.

At the time of publication there were no commercially active TLPs, and the plot involves a conspiracy to destroy Seawitch by competing oil companies.
