BOP Controls and Analytics

Hydril BOP control systems enable safe reliable operation of your equipment. With more functions, higher fault tolerance and subsea reconfigurability, our latest generation of BOP Controls help drilling contractors and operators achieve maximum uptime.

SeaPrime – Subsea Control Systems for Drillships & Semisubmersible rigs

Our fault-tolerant SeaPrime™ Subsea MUX BOP Control System is designed to increase reliability, simplify maintenance, and prevent costly stack pulls. SeaPrime™ is the first control system to include a reroutable smart redundancy feature that lets contractors continue drilling if critical components of a single POD are not available—reducing BOP downtime and the risk of a POD-related stack pull.


SeaONYX is HMH’s next-next-generation surface control system and operator interface, based on the industry-proven PLC platform. With its highly simplified architecture and compact design, SeaONYX is designed to deliver maximum performance at the lowest cost to own. It is reliable, configurable, and easy to maintain. 


The Sealytics BOP Advisor provides access to your control system data while maintaining cyber-security in an easily installed edge device. The system features real-time visualization, BOP systems status, and the ability to manage maintenance activities. With optional cloud connectivity, stakeholders onshore can view/retrieve BOP data that has been historically difficult to retrieve securely. Sealytics enables collaboration between onshore and offshore personnel, driving the quality, speed of decisions, and corrective actions resulting in reduced NPT.
