Nuvia is one of the leading provider of Naturally Occurring Radioactive Material (NORM) management services in the UK. According to the U.S. Geologists have recognized their presence since the early 1930s and use their presence as a method for finding petroleum systems. Much of the petroleum in the earth's crust was created at the site of ancients seas by the decay of sea life. As a result, petroleum deposits often occur in aquifers containing brine (salt water). Radionuclides, along with other minerals that are dissolved in the brine, precipitate (separate and settle) out forming various wastes at the surface, such as mineneral scales inside drilling and production pipe, sludges, contaminated equipment or components and produced waters.

Based on project experience, research, and joint industry development work, DNV issues a number of pipeline codes. These comprise service specifications, standards and recommended practices, and are highly regarded within the international pipeline community. The DNV OS-F101 ‘Offshore Standard for Submarine Pipeline Systems’ provides acceptance criteria and design procedures for pipelines. The standard applies modern limit-state-design principles with ‘safety classes’ linked to consequences of failure. The DNV standard is complemented by several recommended practices (RPs), which give detailed advice on how to analyze specific technical aspects according to stated criteria.

Due to the extreme demands placed on subsea equipment used in the pre-salt E&P Petrobras has been forming various partnerships with local and foreign companies to develop specially designed equipment to tackle the hazards of deepwater pre-salt development. One of the newest partnerships implemented by Petrobras, was for a feasibility study on Flexible pipes for practical oil production in pre-salt area with Japan Oil, Gas and Metals National Corporation (JOGMEC). JOGMEC and PETROBRAS have a long history of research and development partnerships which started back in 2005, for collaboration on mutual benefit O&G exploration and production activities, HSE related matters, and R&D activities of the O&G sector.
