The first, and thus far unique, cell-spar platform was Kerr-McGee's Red Hawk spar (7 ea. 8 m (26 ft) diameter cells). [6] Field-depletion occurred 4 years after production started, so Red Hawk was decommissioned in 2014 under the Bureau of Safety and Environmental Enforcement 's " Rigs-to-Reefs " program, at which time it was the deepest ...
The spar was upended in the fjord, after which the topsides were installed using the floatover technique. It was then towed vertically to the Aasta Hansteen gas field 300 kilometres (190 mi) off Bodø at the northwest coast of Norway. The spar is moored north of the Arctic Circle using polyester moorings to the seabed 1,200 metres (3,900 ft) below.
The Pauli truss is a variant of the lenticular truss, "with the top chord carefully shaped so that it has a constant force along the entire length of the truss." [ 19 ] It is named after Friedrich Augustus von Pauli [ de ] , whose 1857 railway bridge (the Großhesseloher Brücke [ de ] ) spanned the Isar near Munich .

About 1846, he remodeled this design by replacing the counterbraces with a stiffening member fastened to the inside of the posts at points near the top ...
The Braga Bridge is a continuous truss bridge. It was the fourth longest span of this type when it was completed in 1966. This list of continuous bridge spans ranks the world's continuous truss bridges in two listings: The first is ranked by the length of main span (the longest length of unsupported roadway) and the second by the total length of continuous truss spans.
