Tobul’s SEAsure™ depth compensator is specifically designed for offshore drilling and production applications that demand high strength performance and resistance to seawater. The SEAsure™ depth compensator utilizes undersea pressure to compensate for installation depth by allowing seawater into the fluid port. The incoming seawater applies pressure to the fluid filled internal bladder, which is discharged through the transfer coupling (connection block) to the POD. Tobul Accumulators are an integral part of the control and operation of subsea drilling and production systems; and they are used to ensure sufficient hydraulic power to activate hydraulic actuators and motors, electro-hydraulic control PODs, blowout preventers (BOPs) and gate valves for flow control of oil and gas to the surface or other subsea locations. Tobul designs and produces accumulators with high strength alloys and proprietary compounds for extreme duty, superior performance, reliability and longer service life. The SEAsure™ Depth Compensator is designed for 1,500 PSI (103.4 bar) and is built for 2.5-15 Gallons (9.5-57 liters). The SEAsure™ Depth Compensator can be configured with Carbon Steel or Stainless Steel with up to four ½” NPT threaded fluid ports on the transfer coupling (optional threads available); and coated in various customer specified finishes. All SEAsure™ Depth Compensators are ASME Section 8 Division 1 Certified and ASME “U” Stamped.
