How it improves performance

Engineered specifically for drillships and semisubmersible rigs, the below tension ring rotating control device (BTR-RCD) features an 18¾-in clear pass‑through that facilitates seamless drilling-under-pressure operations. Built on a proven, reliable design, the BTR-RCD enables incident-free performance in challenging offshore environments. It offers flexible deployment—installed either independently or as part of the integrated riser joint system—while a single @balance Control™ MPD systems manage both the RCD and chokes for streamlined well control. This integrated approach supports operational efficiency, enhances safety, and empowers continuous drilling progress under pressure.

How it works

The sealed rotating system (SRS) is purpose-built to enhance operational reliability and efficiency during drilling. Featuring a dual sealing element design, the SRS creates a secure, closed-loop annular system that maintains a dependable seal around all drillpipe sizes. This robust configuration effectively contains hydrocarbons and other wellbore fluids while imposing minimal restriction on rotary speed. As a result, drilling operations can maintain maximum efficiency without compromising well control or safety. The SRS empowers operators to achieve consistent, high-performance drilling while supporting reliable, ecologically soundpractices.
