Spider and gimbal

The spider serves as a hangoff point for the riser during BOP running. We offer split spiders and gimbals to accommodate rotary tables of 49.5-in, 60.5-in, and 75.5-in diameter and are qualified up to 2,500,000 lbm hangoff capacity. Our spiders are designed so that the only moving parts are the spider dogs. For improved safety, the 75.5-in spider dogs completely cover the open hole when hanging off a riser joint. The shock mount gimbal allows up to a 5° movement in all directions.

This spider design can be configured to accommodate our Robo-Spider system for risers.

Robo-Spider automated riser-flange-bolt torque system

The Robo-Spider system is the first fully automated riser flange bolt torque system capable of reducing riser flange bolt torque time by up to 70% while increasing rig floor safety.

Diverter

We also offer the CF-A diverter for floaters and the CF-B diverter for jackup rigs.

• Our CF-A diverter supports up to 75.5-in rotary tables and has a hangoff capacity of up to 2,500,000 lbm. It is a single annular packing element with a pressure rating up to 500 psi. The CF-A model features four hydraulic locking dogs that reduce hosing and provide simplified running and retrieval of the diverter assembly.
• The CF-B diverter supports up to 47-in rotary tables and is qualified up to 2,000 psi. Packers can be split and hinged to allow them to be changed out with pipe in the hole. J-slot type running tools are entirely mechanical.
