Motion compensator hose for constant pressure on drilling string

Motion compensator hose – stabilize vertical wave action

Motion compensator is a hydraulic system to compensate for the up and down motion of the rig vessel to keep constant pressure on the drilling string. The compensator is pressurized by an air-oil accumulator supplied by motion compensator hose. It is specially built for the stabilization of rotary drilling and pumping equipment against vertical wave action on offshore drill platforms.

Hence, the hoses must be compatible with various fluids to be used. Phosphate ester fluids are not recommended.

Construction:

• Tube: Black Neoprene Type A;
• Reinforcement: four alternating layers of spiral wire;
• Cover: Black Type A Neoprene synthetic rubber;
• Fittings: stainless steel or carbon steel interlock plus fittings.
• Surface: cloth impression.
