Tanker Vapor Report Released, Concludes Safety Systems Operate as Designed

Alyeska Pipeline recently released its report on the comprehensive management review of the Tanker Vapor Control System. A critical safety system checkout done as part of the management review verified that all the safety systems functioned as designed.

The overall management review was initiated to resolve known operational issues and to accelerate the discovery of any further potential issues. Additional goals of the review were to assess the effectiveness of the system since start-up and determine if the system is functioning as designed.

The comprehensive review concluded:

• The critical safety system checkout confirmed the system functions as designed. ·
• There is no evidence to substantiate the concern that the system poses a threat to the safety or integrity of TAPS. ·
• Consistent use of operating and maintenance procedures is critical.

The management review was conducted by creating five work groups, each with a specific scope: Management Controls, Operating Controls, Hardware Performance, Training, and Procedures. Each work group, consisting of representatives from Alyeska, the USCG, JPO and RCAC, completed their review and submitted conclusions and recommendations for improvements. Among the recommendations are several hardware fixes including replacing the oxygen analyzer flow switch and evaluating the protective coating materials and their application on the Fenwal Valve gate.

Alyeska is addressing all the recommendations listed in the Tanker Vapor Control Management Review Report.
