Offshore Cementing Systems
Gulfstream Services’ RCH Top Drive Cement Head system is designed to drop plugs, darts or balls of any type or length during cementing or circulating applications, all while reciprocating and rotating string weights up to 3 Million pounds.
The RCH system has been engineered with a modular design and can be configured with a Swivel or Pump-In Sub, or as a stand-alone head, depending on your particular application and needs.
The Gulfstream Services RCH System has been successfully deployed on over 3,500 jobs worldwide. Contact us today to learn more about our offshore cementing equipment rentals.
