Abstract: The structural design of the offshore oil and gas platform development project requires the weight control of the topside facilities,which directly affects the structural design and engineering construction resources of the offshore platform. In the design process,the weight control is the estimated value,but it needs to be as accurate as possible to obtain reliable design results and optimize the structure and construction resources. Combined with the project practice,this paper elaborates the evaluation method of the main specialties involved in the weight control of topside facilities on offshore platform,which provides a reference for submitting the accurate weight control of the offshore platform.

Key words: offshore oil and gas platform, weight control, weight center, weight uncertainty factor
