Self Supported Steel Stacks: Meca has designed many different types of self supported stacks, ranging in height from 6 m (20 ft) to 100 m (328 ft).  Some Special design considerations have included:         * Single Piece Lift of Stack         * Special Breech Openings         * Low Temperature           Applications         * "Piggy Back" stacks         * Vibration Design         * Retrofit of Existing Stacks
Guy Wire Supported Stacks: Very few companies perform the design of guy wire supported stacks.  Meca has designed many guy supported stacks ranging from 15 m (50 ft) to 167 m (550 ft) in height.  We can save you considerable time in money due to our experience in the area of guyed stack design.  We have performed the following types of special designs: *  Single Piece Lift of      Stack    (sometimes done from    multiple lift points) *  Low temperature     Design    (Ambient and     Cryogenic) *  Piggy Back design of    one  stack off another *  Unique Guy    Arrangements * Tandem Stacks
Derrick Supported Stacks: Extensive experience designing derrick supported stacks: * 3 Sided or 4 Sided * Pipe Members * Flat Faced * Demountable
Offshore Booms: Meca has designed flare booms for offshore.  This include guyed booms and fixed booms mounted on offshore platforms and FPSO's.  These booms are designed to API RP 2A.
Piping Analysis: We can perform piping analysis using conventional piping analysis software, to perform flexibility analysis per ASME B31.3.
Pressure Vessel: Pressure vessel design per ASME Section VIII, Div. 1.
Fitness For Service: Using API 579 'Fitness for Service' we can rerate components (Vessels, Piping, or Tanks) based upon an existing flaw or defect.  This can be a very effective tool that can be used to save companies money in lost downtime and repair expenses.  This is frequently used to assess damage due to local or general corrosion, gouges, or other common defects.
Nozzle Loads: We can perform Finite Element Analysis for Nozzle Loads.  This can save considerable money over using WRC 107/297.
Finite Element Analysis: Finite element analysis does not always have to be expensive.  We encounter certain types of problems repeatedely involving stacks, piping, and pressure vessels.  Therefore, we have become very adept at building certain geometries very quickly to provide a cost effective solution.
Commercial Software: We use the following commercial software to perform our design/analysis services: * StaadPro (Structural Analysis) * Compress (Pressure Vessels) * Pipeplus (Piping) * Caesars (Piping) * FE-Pipe (Finite Element Analysis) * Autocad (Drawing) * Stackdes (Stack Analysis) * Many other in-house developed programs for specialty design.
