Principle of the HAZOP method
For HAZOP analysis, firstly an analysis team consisting of professionals of process, equipment, electrical instrumentation, security and other domains is set up, an expert with wealth of experience, work ability and extensive knowledge is selected as the analysis headman or president.
Application Examples 2.1 Analysis Objects A shallow water catheter frame platform in Jidong oilfield was taken as the example.
The platform stands in depth about 7m and 32km far from Caofeidian Island which is typical of shallow water simple steel catheter frame platform, including three wellhead platforms, a production platform, which are connected through a trestle, supported by a mixed transportation pipeline of undersea oil, gas and water, a injection pipeline and a 10KV composite submarine cable.
The main functions of the platform are oil and gas heating, metering, gathering and transportation and water injecting.
Meanwhile, injection water of the wellhead platform is provided through seabed water injection pipeline from the artificial island.

Samples are collected by professionals at each sampling site sewage treatment station.
The amount of collected untreated sewage water samples is 337, amount of treated sewage water samples is 216.
After testing, water samples that not been treated do not meet the effluent standards. 216 treated water samples after disinfection, 183 qualified, the pass rate is 84.72%.

Among all the drilling fluid systems, water-based drilling fluid (WDF) is the most widely-used and investigated.
In other word, it cannot function in water but in brine instead.

With regards to the characteristics of inter-basin water transfer projects, a 3d visual simulation (Three-Dimensional Visual Simulation, 3DVS) method for inter-basin water transfer project was proposed.
Based on the established digital model, the simulation of channel water were realized .The Yuzhou section of South-to-North Water Transfer Project is taken as a case study. 3D visual simulation provides an effective way for the construction management and decision-making for inter-basin water diversion project.
Visual simulation modeling Due to the linear characteristics of Inter-basin water transfer project, it has broad scope and abundant substance on the surface, the scenes mainly include water transfer channel,farmland waters, green belt and bridge.
Before the texture mapping technique is used, the professional image processing software could be used to control the size, the proportion, the format of the textures rationally.

The Green Building has an important strategic mean for saving energy, water, material, and protects sustainable development in natural environment.
At the completion of the green building design, it needs the more professional team operation.
According to theory that we knew the team needs to be more powerful, has professional business ability and comprehensive quality, the project needs more investment on Green Building consulting design cost.
However, the technical incremental cost of Green Building is saved more place, energy, water, material, internal environment, and management than the common building.
Water saving and water using Water saving equipment, water sewage system, new water resource using, efficient irrigation technology.

Professionals are interested in particular in terms of alternative and high local energy sources but also from the perspective of sustainable development.
Many of these containers is a combination of water and a material of high density.
Measuring Procedure: First, it was necessary to determine the actual loss calorimeter (TA), derived from the well-known calorimetric equation: (1) The loss was assessed by means of water, respectively two samples of water of different temperatures and consequently loss was tested on a sample of known steel capacity.
The calorimeter was charged with water weighing about 6 kg, the portion of the water was recorded with an accuracy of 0.01 g.
For comparison in the Table 2 are supplied water and concrete.

The system has functions such as lakes and reservoirs’ water quality real-time monitoring, teletransmission and location, water quality data analysis, water bloom prediction and emergency treatment decision-making.
The water bloom’s formation destroys biological diversity of water body, and has serious constraint on economic construction and social development.
After obtaining information of water body, the corresponding water quality information can be analyzed, and the law of water environment’s variation will be got.
Figure1 Information system structure 2 System Functions Introduction 2.1 GIS-Based System Development In recent years, due to the development of new technology, the increasingly richer obtained or shared regional social economic data, and the expansion of GIS applications and further professional development,traditional big geographic information system has gradually been replaced by GIS secondary development [4].
The data come from matched water quality online detector which is embedded within the high-precision beacon machine and YSI water quality sensors.

The results of the paper show that there is not a meaningful coherence between scientific researches and professional requirements.
Moreover academic disciplines generally focus on theoretical era rather than professional fields.
Currently behind other areas such as water treatment and remediation, the Architecture, Engineering, and Construction (A/E/C) industry might accommodate broad applications of nanoproducts.
Conclusion The results of the paper show that there is not a meaningful coherence between scientific researches and professional requirements.
