Summary
A subsea safety-valve seal failure allowed hydrocarbons into hydraulic lines at a Gulf of Mexico production platform, releasing an estimated three to 50 barrels of hydraulic fluid and oil. The alert describes ROV sampling and leak isolation, and recommends considering hydraulic-system monitoring, alarm configuration and pressure management during leaks and platform evacuation.
