The article describes application of currently
widely distributed technology of laser scanning during geometric control and
construction supervision at various stages of facility construction. Surface
laser scanning was used for two process units of Rosneft Oil Compant refineries
by specialists of Company’s design institutes – VNIPIneft JSC and
Samareneftekhimproekt JSC. Results of surface laser scanning were prepared in
specialized software and then compared with 3D design model of the facility;
deviation chart was prepared based on the comparison in addition to visual
analysis. It is notable that the chart shall be prepared on the basis of
received data in computer-aided mode. Applied approach gives an opportunity to
use surface laser scanning as mandatory element of construction supervision
together with designer supervision in key points of facility construction.
Deviation analysis gives an opportunity to estimate availability of deviations
from design solutions, availability of more serious violations of design
decisions, fact of maintaining required levels at constructed facility.
Analysis results give an opportunity to provide specific instructions to
originators at the facility to incorporate changes already at the construction
stage. Successful implementation of projects on comparative analysis of 3D
model and changed data in the form of a point cloud allows to apply safely
surface laser scanning technology for supervision of oil and gas industry
facilities construction. This type of work is required to reveal discrepancies
and incompliance of facilities. It allows to decrease considerably time for
gathering, analysis and provision of a result. Correctly structured process of
work execution almost eliminates human factor considerably influencing final result.
