Summary

 
The purpose of this study is to develop a method for assessment of allowable risks in operation of subsea production systems (SPS). Main hardware components of subsea production systems are described. Hazard and operability analysis (HAZOP) is used to identify sources of potential accidents as well as to define acceptable risk criteria including commercial, environmental and human safety risks. A computation program is developed to assess these risks, and leakage risks are estimated for SPS at the Kirinskoe gas condensate field. This study is important in view of the necessity to develop an integrated approach to risk as-sessment because most of the generally adopted standards and regulations are focused on other fields of application.
