The common history of DNV GL goes back to 1864 when Det Norske Veritas was founded in Oslo, as a membership organisation, with the aim of providing reliable and uniform classification and taxation of Norwegian ships.
Members of the society were Norway’s mutual marine insurance clubs, which joined forces to establish uniform rules and procedures for assessing the risk of underwriting individual vessels.
The merger of DNV and GL, Det Norske Veritas (Norway) and Germanischer Lloyd (Germany), in September 2013, led to the creation of DNV GL, a world leading ship and offshore classification society, a leading independent service provider in the oil and gas sector, a powerhouse in energy and renewables, and one of the world’s top three certification bodies.
DNV GL is the world's largest classification society with 13,175 vessels and mobile offshore units (MOUs) amounting to 265.4 mill gt in its portfolio, which represents a global market share of 21%.
The organization is also a reference in renewable, alternative and conventional energy.
It is the world's largest technical consultancy to onshore and offshore wind, wave, tidal, and solar industries, as well as the global oil & gas industry - 65% of the world’s offshore pipelines are designed and installed to DNV GL’s technical standards.
 Today the DNV GL Group comprises approximately 16,000 employees operating in over 100 countries.
