Safe well access throughout the lifecycle of the well 

The Halliburton subsea safety system is a hydraulically operated dual “fail-safe closed” valve system designed as a primary well control barrier combined with a passively orienting latch mechanism. The subsea safety system is a critical part of any landing string flowing hydrocarbons to a semi-submersible or dynamically positioned drilling vessel. Deployed within the drilling blowout preventer stack, the subsea safety system provides dual barrier well isolation, along with a means of disconnecting and isolating landing string
