On July 1998, with the 2014. implementation of the Institutional reform of the CNPC strictly follows by the combined strategies State Council, CNPC was reorgnized to become of increasing resource capacity, expanding market an integrated oil company of cross-regions, cross- shares and consolidating the international role, and industries and cross-countries, it adopts modern persists in regarding technical innovation as a key enterprise system to realize the integrations of framework to advance technological progress. To upstream and downstream operations, internal and develop its core businesses, focuses will be placed external trade, production and marketing. CNPC's on the solutions of key bottleneck technologies business covers six main sectors: oil and gas and key proprietary technologies. Thanks to operations, petroleum engineering service, petroleum continuously improving of the technical innovation engineering construction, petroleum equipment system, optimizing the configuration of technological manufacturing, financial services and new energy resources and strengthening the construction of development. In 2014 CNPC produced 113.67 million strong talent teams, CNPC’s technological creativity tons of crude oil and 95.46 billion cubic meters of has been considerably upgraded. Consequently, a natural gas, while crude processing volume reached large number of technologies have been developed 150.2 million tons. The total revenue of RMB 2,730 independently, with its own intellectual property. billion with a profit of RMB173.4 billion had been achieved the same year. The jacket platform technology is one of representatives for major innovations of CNPC. OFFERING ENERGY SOURCES, CREATING HARMONY 2 1INTRODUCTION The jacket platform fixes the structure in the 4 major technology series such as topside module seabed using piles and includes three parts such design technology, jacket design technology, topside as topside module, jacket and pile foundation. The module construction and installation technology and jacket platform is characterized by good adaptability, jacket construction and installation technology and 25 high safety and high reliability and has become the characteristic technologies. They have been widely primary structure form in the development of beach applied in the development of offshore oil and gas fields and shallow sea oil and gas fields. in Bohai Bay area. CNPC has greatly increased its offshore engineering Through steady development of comprehensive service capacity based on the technical development offshore engineering service capacity, CNPC has concept “perfecting beach fields, development shallow achieved leapfrog development and has EPCI sea fields and reserving deep sea fields”. In terms of engineering general contracting capacity of large jacket platform technology, CNPC has formed totally jacket platforms.
