Unquestioning application of simplified methods or basic computer models can result in gross under- or overestimates of transient pressures & forces or ignorance of hazards. This leads to unnecessary worry and higher surge control costs.

HAMMERTM * was originally created by EHG as a result of over 15 years of continuous research and development led by Dr. Alan Fok.1 In 2003, Haestad Methods Inc. acquired Hammer in 2003 and now markets it worldwide.


EHG for SNC-Kilborn (a division of SNC-Lavalin)

Track Record: EHG has used HAMMERTM for over 15 years on many advanced projects (you can download 1-page descriptions from this site).  It  incorporates practical experience in the municipal (water & wastewater), mining (slurry), industrial (steam) and hydro sectors.

  

Technology: HAMMERTM's advanced 1D numerical engine can simulate compressed air vessels, surge tanks, surge control valves and pumps for systems ranging from single lines to large networks with thousands of pipes conveying water, oil, slurry, steam or natural gas.
