Topside Compact Solution

Reducing Size in Offshore Topsides Valve Automation

Good actuator design revolves around many features and benefits.  In applications on offshore deep-water production facilities, floating production, storage and offloading units (FPSO) or floating Liquefied Natural Gas vessels (FLNG), size and weight are among the two most important aspects.  Engineers and designers of these facilities are continually searching for way to construct lighter weight and more compact topsides, as these translate into significant cost savings with steel reduction and lower installation costs.  Bettis™ G-Series scotch-yoke actuators, based on 60 years of performance in the oil & gas industry, provide the necessary construction features for accomplishing these savings.

Challenge
The cost of constructing an offshore topsides production facility ranges from approximately $35,000 - $50,000/ton.  Much of this tonnage is for steel supports, decks, piping and skid-mounted equipment.  Reductions in these costs can generate millions of dollars in reduced capital costs for a deepwater project.  Engineers and operators are charged with a goal of minimizing weight and footprint in the design of the facility.  This effort entails reducing weight of equipment and minimizing space with tighter, more compact piping runs and smaller equipment packages.  These reductions are difficult without compromising safety and performance, both in current operations and future expansion possibilities.

Solution 

  • Bettis  G-Series reduces weight of a comparable scotch-yoke actuator by as much as 47%
  • Bettis  G-Series actuators are up to 25% smaller in their dimensional envelope  with  torques comparable or higher than conventional scotch-yoke designs
  • Bettis G- Series actuators have safety features specific for offshore use that include: 
    • Internal tie-bars and spring for corrosion minimization
    • Highest operational efficiency
    • Guaranteed torque minimums
    • Five-year warranty
  • Modular construction makes G-Series more economical for replacement parts and upgrades , reducing operating and maintenance costs.
