Offshore oil and gas service and supply industries

Primary tabs

The French offshore oil and gas service and supply sector is a world leader and the 2nd largest exporter of offshore extraction support services (with more than 90% for export), a position which it shares with Norway and the United Kingdom. Turnover has risen from € 3.5 billion at the end of the 90's to around € 17.55 billion today. 

The sector alone accounts for more than a quarter of the value of production in the maritime economy. 

It has also a particularly strong, acknowledged reputation in deep and ultra-deep offshore operations. The offshore oil and gas service and supply industry consists of a group of companies with specially designed fleets performing the important survey and construction tasks necessary for the exploration and exploitation of oil and gas deposits at sea. It includes equipment suppliers and service providers, particularly ship owners and operators, and engineering and design firms. 

In the coming years, developments in deep and ultra-deep offshore are likely to be the main source of growth in offshore oil and gas production, and there are also plans to use certain methods for subsea mineral exploration and exploitation, the next great challenges in offshore subsea extraction.

Pour les installations techniques 

For technical facilities 

Saipem (see page 56) engages mainly in offshore oil activities (construction of rigs, seabed-to-surface connections, floating production systems and pipelines), LNG and drilling. 

Doris Engineering specialises in technical studies, project management and assistance for the oil and gas industry. 

For offshore services 

BOURBON (see page 21) is a specialist in offshore maritime services among others, where it has become one of the world leaders. 

COMEX (see page 21) and Subsea 7 are pioneers in sub-sea engineering, technology and services by divers or remotely operated vehicles. 

An innovative industry 

World firsts such as the first deep water platforms for harsh environments (Arctic), the first jack-up platforms and firsts in smart drilling, electromagnetic data transmission and new devices for laying gas and oil pipelines in deep water have all been produced by French technology and expertise. 

With the prospective formation of a new industrial sector of "deep sea mineral exploration/ exploitation", French companies which have honed their skills in oil and gas and offshore activities are coming to the fore in terms of both R&D and new technologies, such as Technip, ERAMET, DCNS, COMEX, Fayat Travaux Sous- Marins, and even Louis Dreyfus Armateurs, BOURBON and CRÉOCÉAN
