description: Nowadays it is hard to imagine big factories and businesses operating using no natural recourses. We have all natural resources used in form or another. Oil and gas are not exceptions here. It is extremely complicated, expensive and comprehensive in many aspects to extract these resources. Continental shelf reserves about quarter of oil and gas resources. Offshore platforms are absolutely essential for surveying and exploration. 
LUN_A with âArcâ deck fixed offshore platform is the object of a study.
The aim of the study is estimation of a platform stability during transportation operation and using operation under determined loads and normal use.
The following researches allowed reaching the results:
1) Ice, water flow, wind and wave loads calculation and its action
2) Sheer and overturning calculation under determined loads
3) self-righting stability calculation
Theoretical research methods such as modeling, analysis, calculations and aggregation were implemented in the study
Loads distribution, sheer and overturning calculation results were reached. It shows allowable stress value doubles platformâs design and platform will able to withstand determined loads. Calculation result of self-righting stability also shows platform is stable up to 25Â° static heeling angle and 30Â° static trimming angles. dynamic heeling and trimming angles were determined
