Troll A is a tubular floating concrete structure submerged to 350m

Estructuras tubulares de concreto submergido a grandes profundidades son muy commun. Tambien muy commun barcazas de concreto tipo panal como Nkossa. Asi un submarino de concreto no es fuera de los limites probados y establecidos de la ingenieria de concreto.

The legs of Troll A

2259264492_6e13082fac_o.jpg

They had to hold the full water pressure of 350m depth (at mating process). And they are now under 303m hydostatic pressure since decades. The engineers of the fotos are standing at the bottom of the legs.

The legs have 24 m diameter and 1 m wallthickness. The structure was built in a floating building site - ballast water is in the cells of the base structure.

Check the slip form method (no one shot pour).

Troll A is a interesting case in the sense of limits for tubular concrete structures under hydrostatic load all condeep structures have excellent long term performance records in marine ambient that pass the service life expectancy of compareable steel structures a factor 10 and more. 200 years of maintenance free service life compared to only 20 years of service life with a tight maintenance shedule for steel make floating concrete structures the top choice for permanent floating structures on the ocean.

Great article, fantastic technology and fabulous pics. Would love to be a part of building a concrete floating structure. Though I am an expert at installing coloured concrete and stamped driveways, these kind of projects propel to give my best.
