Modeling technique for researcha washout of soil at offshore structures basic basis

Leonid G. Shchemelinin, Valeriy I. Denisov, Kirill E. Sazonov

For development of deposits of the hydrocarbonic raw materials located in a shallow part of a coastal shelf, offshore structures of gravitational type are widely applied. The basic bases of such structures are established directly on a sea-bottom. While in service offshore structure the sea-bottom soil near its basic basis and under it is exposed to external influences from a sea current, waves and also from propellers streams of ships, approaching to the structure. As a result there is a washout of the soil basis to loss of the area of a basic surface that can lead to loss of stability of the structure on sea-bottom. Works on research of process of soil erosion near the basic bases of gravitational type offshore structures by means of carrying out of modeling tests are carried out in shallow water towing tank of KSRI since 2000. As this towing tank initially didnt intend for carrying out of such experiments, in addition to its equipment the special experimental means have been created. Also methods of carrying out of modeling experiments on research of washout of a soil near the objects established on it have been developed and tested. The article acquaints with the equipment used for carrying out of the modeling experiment and techniques of their carrying out.

Computed radiography and radiographic testing with X-Ray films. The comparison of artificial flaws detection. The practical recommendations for CR technique applications and equipment maintenance

Kirill A. Bagaev, Anatoly B. Spirkov

The paper describes the experimental workfor quality of radiographic images taken using X-ray film and computed radiography systems (CR) determination. The experimental studies were briefly described. The results of the research were provided. The main emphasis is made on the comparison of the flaw detection in radiographic inspection with films and with the CR systems. The article also provides the practical guide for the CR systems selection and their applications. There is also a shortoverview of periodical user tests that should be performed to verify CR system performance.The article ends with conclusions aboutthe applicability of Computed Radiography technology in the industry.

The conclusions about the applicability of these standards in Russia were performed. Computed radiography systems from various manufacturers were observed. Most attention was paid to the new model of Duerr HD CR 35 scanner. The technical characteristics of computed radiography systems were compared. The review of foreign CR standards was performed. 1. It is important to use independent expert conclusions while choosing CR system. The BAM institute of Metal is one of the most respectable ones. 2. Computed radiography is used abroad for much longer time than in Russia. There have been developed and adopted relevant standards. It seems, that Russia needs the immediate implementation of the CR standard, which should be based on international standards. This greatly simplifies the use of technology adopted by the Russian NDT community.

The advantages and disadvantages of the existing methods of monitoring the state of the construction projects. Isolated aspects of the problem of having to use stationary monitoring systems engineering spatial position of objects. The measurements are made relative to the reference lines created by laser radiation generated by special optical components. Register offsets produced relative to the center of the laser scanning radiation of a master reference direction by the reflected laser beam in the direction of the pulse analyzer, rigidly attached to the object to be measured. When measured basic direction defined by the center scan aligned to the centers of the first and last analyzers measuring brand with the required accuracy. Automation of processes controlling the operation of the system allows us to hope for a speedy completion of the entire instrument of measuring complex and successful implementation in those sectors of the economy requiring highly accurate in determining the critical deformation of engineering structures.
