Exxon's Lena guyed tower, installed in 1,000ft. water in the Gulf of Mexico, is discussed. The Lena tower is designed to move in response to wave forces rather than resist them rigidly, as is the case with conventional platforms. Selection of tower components to satisfy requirements resulted in a complex geometry which presented design challenges. Buoyancy will serve as a stabilizing force for the tower by adding to the restoring force of the guying system. Flexible J-tube pipeline risers were developed to avoid excessive stresses in the pipelines and J-tube pipelines and J-tubes at the mudline. Exxon's Lena platform is to-date in the second deepest water in the world, and at 1,305 ft total height, is the tallest.
