BM SUMER Consultants

More than 40 years experience
in research and consultancy


BM SUMER originated from the consultancy B Mutlu Sumer Professor, C Ing., based in Kgs. Lyngby, Denmark, active over more than 25 years in Coastal, Offshore, Hydraulic, River, Marine Civil Engineering. With speciality areas such as scour / scour protection around marine and hydraulic structures; marine soil liquefaction and its implications for marine structures; current and wave loading on and hydroelastic vibrations of marine / hydraulic structures including pipelines; river engineering; coastal and river sediment transport.

Professor Sumer was joined by Dr. Kirca in 2015 to set up BM SUMER. Since 2016, BM SUMER Consultancy & Research is affiliated to ITU ARI Teknokent, the technology & science park of Istanbul Technical University. BM SUMER has been awarded in two categories of BEETECH 2019 startup awards by ITU ARI Teknokent, (1) the award for the highest R&D turnover, and (2) that for the highest R&D export. BM SUMER provides to clients as consultants in-depth insight and creative solutions in matters related to all aspects of Coastal, Hydraulic and Offshore Engineering.

Extending beyond the classical consultancy services, BM SUMER consultants provide services in which consultancy and advanced-research go hand in hand. BM SUMER consultants employ cutting-edge methods and technologies, including advanced mathematical / numerical modelling as well as physical modelling studies to achieve the most optimal solutions to engineering problems.
