Design and construction of HYSY981

This paper focuses on the independent design and construction of HYSY981. HYSY981,which China National Offshore Oil Corporation(CNOOC) possesses its intellectual property right,is brought forward by advanced research,concept design and combined basic design. The key technologies are the researches concerning global design,system integration,platform positioning,global performance analysis,structural strength and fatigue analysis,environment effect assessment of South China Sea,basin test and tunnel test,and construction technology of platform. Core technology of design and construction for the 6th deep water semi-submersible rig is held. Independent detail design and construction are also accomplished. These have improved technology of key equipment for China offshore oil exploitation.

First ERW Ф610 Steel Tube Production Line Brought on Stream

The first domestic ERWФ610 high-frequency straight-seam steel pipe production line was built in Shanghai Zhongyou TIPO Steel Pipe Co Ltd recently. This steel pipe production line initiated inside China has drawn the attention from many enterprises including PetroChina and CNOOC. It is known that the first batch of products have been transported to the construction site of the West-East Gas Transmission Project.

Study on Chinese companies＇ perception on overseas public listing

This paper reports an investigation on Chinese companies＇ perception on overseas public listing. The investigation is mainly based on a questionnaire survey. The result shows that Chinese companies overwhelmingly accept overseas listing as a preferred option, which may shed some light on other Chinese companies in their evaluation on seeking overseas public listing as a strategic option to the overseas exchanges in their efforts of wooing the Chinese market.

Commercial Application of RMC Technology in the 1.5 Mt/a Hydrocracking Unit at Shanghai Petrochemical Company

The RMC technology developed by RIPP has been applied in a 1.5 Mt/a medium pressure hydrocracking unit at Shanghai Petrochemical Company. The unit was successfully put on stream in September 2002. Calibration of the performance of the commercial unit has shown that the RMC technology has higher hydrogenation activity and selectivity, and high quality product can be obtained under lower reaction temperature. The heavy naphtha with less than 0.5 ppm of sulfur and 58.5 m% potential aromatic content is a good feedstock for catalytic reforming unit. The diesel with less than 0.5 ppm of sulfur, 6.6 m% aromatics and cetane rating of 56 is a high-grade diesel fuel. The hydrocracked tail oil containing more than 14 m% hydrogen and mere 1.7m% aromatics could be used as a good feedstock for steam cracking process to produce ethylene.

China's Oil Majors Hit by Falling Prices in First Half

China’s national oil and gas companies saw their profits slump during the first six months of 2015,with the levels falling to the lowest in five years,according to financial reports.The first-half reports for China’s＂big three＂ oil companies - China National Petroleum （CNPC）, China Petrochenlical Corporation, as Sinopec. and China National Offshore Oil Corporation also known Corporation （CNOOC） - showed that CNPC＇s profit tell by more than 60 percent to 25.4 billion yuan （US$3.98 billion）, Sinopec by 22 percent to 25.4 billion yuan, and CNOOC by more than 50 percent to 14.7 billion yuan.

The relationship between extension of lower crust and displacement of the shelf break

With deep sea petroleum explorations become more and more popular,some geological phenomena have emerged:extension of lower crust and upper crust is inhomogeneous;shelf break has been moved rapidly after crustal stretching.These geological phenomena are important to the continental margin evolution.To investigate the thinning of the whole crust and the contribution of the upper crust versus the lower crust to the crustal stretching since the Cenozoic,we calculated the stretching factors of the upper and the lower crust based on the 13 seismic lines in the Baiyun Sag from CNOOC.The results indicated that the whole crustal thickness decreases seaward while the whole crustal stretching factor increases from shelf to slope.Our calculations showed that the lower crustal stretching factor is higher than that of the upper crust in the Baiyun Sag.In the Cenozoic,deformation of the Baiyun Sag is controlled mainly by ductile shearing rather than brittle shearing.Based on the numerical modeling,we can conclude the initial crust in the Baiyun Sag is thermally attenuated.The stretching factor(β)of the lower crust increases from the north to the south of the continental margin,indicating two stretching centers:the Baiyun Sag and the Liwan Sag.The geometry of the shelf break and theβisoline trap have the similar trend in 23.8 and 13.8 Ma,both located in the intense deforming zone of the lower crust,and therefore we conclude the stretching and flowing of the lower crust cause the displacement of the shelf break before and after 23.8 Ma.
