About IBL Engineering Office
Ingenieurbüro Dr.-Ing. Gert Lau (IBL), located in Gummersbach, was founded in 2001 and offers structural mechanical calculation and consulting services for components in process and plant engineering. Building on more than 30 years of experience with strength calculations in steam boiler, vessel, and piping construction, we perform stress analyses for pressure vessels, heat exchangers, synthesis gas coolers, piping, fittings, valve constructions, as well as mills and crushers. The design adheres to national and international regulations such as ASME I and VIII/1+2, ANSI B31.1 and B31.3, EN 12952, EN 13445, EN 13480, EN 1591, AD 2000, TRD, PD 5500, and Stoomwezen. In addition to analytical dimensioning calculations, we offer numerical structural analyses based on the Finite Element Method, including stability, fatigue, creep strength, and vibration analyses. The office specifically supports small and medium-sized enterprises throughout the entire design and manufacturing process, as well as in the sales of pressure and temperature-stressed components, from design to construction, manufacturing, and assembly up to commissioning and damage analysis. Customer industries include boiler manufacturing, chemical plants, nuclear power plants, coal gasification plants, and gas turbines.
