In the last twenty years offshore oil development is being increased below the deep level of 1,500 m (5,000 ft) arriving to the ultra deep level of almost 3,000 m (9,800 ft) in several parts of the world as Brazil, Gulf of Mexico and West Africa with increased technical demand because of the severe conditions.
These challenges include methods and equipment that will be adapted or designed specifically for deep water contraints as high water pressures, low temperature and distance from vessels or platforms. Some companies are developing some capability to install equipment and systems in the sea bed in order to offer solutions and the necessary assurance. In the other hand new advances in materials as nanotechnologies are progressing in a very fast rate creating advanced materials and solutions for critical operations or new challenges that are each time more close to the industry in general (oil & gas, mining, aerospace) with use of innovative material and products.
This paper describe the computer based research comparing a chamber or hull for installation of equipment and systems for oil production in conditions of "deep water" and "ultra deep water" fabricated with use of carbon nanotubes (CNT) and the same structure built with use of high strength low carbon steel  ASTM A710 which is an age hardening, alloy steel used where weight reduction, ease of fabrication and reduced welding costs are important. A710 is used in the manufacturing of jack-up rigs, construction equipment, pressure vessels, truck frames, piping components and shipbuilding.
