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.展开更多

While the street design is seemingly a technical means for physical space, essentially it is the redistribution of urban space rights. This paper argues that street design should focus on the 'street right,' which can be divided into the right to pass and the right to stay, and it may as well be divided into permanent right and process right. Permanent right mainly includes property right and use right, and process right includes participation right and decision-making right. At present, there are many problems confronted by streets in China, such as uncoordinated division of property right between public and private parties, unfair spatial distribution neglecting the use right of slow traffic, less participation and no decision-making right for citizens during street design process, etc. Based on recent design practices in Shanghai, Xiamen, Shangyu, and several other cities, this paper explores strategies in terms of the coordination and integration of property right and space, fair distribution of street use right, and the public empowerment in street design.展开更多

This paper analyzes street spaces as public goods, or their nature as a 'public pool,' from the perspective of property rights. After conducting a picture for the use of public street spaces in two innovative districts in Beijing via big data description and field investigation, this paper analyzes the use of public spaces from the perspective of property rights, spatial supply and demand, and the distribution and management of public goods. It further proposes three strategies for street design transformation, including refined management, design integrity, and planning priority transformation.展开更多
