Offshore platforms are structures that provide production and living facilities for offshore drilling, oil production, gathering and transport, observation, navigation, construction and other activities. The marine environment is complex and varied — from simple water and salt intrusion to special corrosion and pressure requirements — all demanding professional products. With the development of offshore oilfield exploitation, the number of valves required for offshore platforms is gradually increasing. Offshore platforms require shutdown ball valves, check valves and multiplex valves. SUFA has a professional special-performance testing laboratory and advanced equipment, and with a professional technical and service team experienced in many years of offshore platform projects, provides users with systematic solutions for the different requirements of various offshore platforms.

According to the vessel naming regulations of China National Offshore Oil Corporation (CNOOC):

All new vessels and platforms under CNOOC are named "Haiyang Shiyou xxx" (Offshore Oil xxx);

9 is the code for "drilling platforms", for example 2 is pipelaying vessels, 7 is geophysical survey vessels, 5 and 6 are support vessels, and so on.

8 is the code for deepwater drilling platforms; 3 represents 300ft jack-up drilling platforms and 4 represents 400ft jack-up drilling platforms.

1 is a serial number, usually at the leader's discretion.

Classification of Offshore Platforms

China's first offshore oilfield — the Chengbei Oilfield — is located in the southwest of the Bohai Sea, 84 kilometers from Tanggu Port. The development area covers 11.5 square kilometers, with peak annual output of up to 500,000 tons. The oilfield has 2 groups of production platforms, each platform including 1 vertical well and 26 directional wells; a submarine oil pipeline more than 2 kilometers long connects the two platform groups and delivers the produced crude oil to an offshore loading terminal for direct export.

The Chengbei Oilfield was developed jointly by China and Japan. Before the joint development began in 1980, the Chinese side had already worked on it for 3 years and drilled 8 wells. After the reform and opening-up, China's offshore oil exploration and development grew mainly through international cooperation, being one of the first industries in China to open to the outside world. By September 1996, China's offshore oil production reached 10 million tons per year — the first time annual output exceeded 10 million tons since the petroleum industry ventured offshore, marking a new milestone for China's offshore oil industry.

What types of offshore platforms are there, and what are their advantages and disadvantages?

The term "operational platform" refers to the carrier part of various modern weapon systems that has a transport function and serves as the basis for weapons. Analyzed in this way, there are many types of maritime operational platforms, such as: various surface vessels (aircraft carriers, cruisers, destroyers, frigates, etc.), submarines, large seaplanes, amphibious tanks/infantry fighting vehicles, temporary artificial islands, radio-controlled vessels, etc.

Classification and advantages of offshore platforms

Informatized operational platforms include: land operational platforms, maritime operational platforms, air operational platforms and unmanned operational platforms.

Informatized operational platforms refer to weapon carriers — such as tanks, artillery, aircraft and ships — equipped with extensive electronic information equipment and centered on information and information technology; they are the platforms on which C4ISR systems rely. These operational platforms are the nodes of automated command systems and the important material foundation for automated command systems to exert their strike capability.
