Who we are? About Us

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. Today, 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.

Mobile App Calculation Types

MOMENTARY LIQUEFACTION
Momentary Liquefaction
Conducts mathematical modeling for assessment of momentary (instantaneous) liquefaction potential of seabed under wave trough.
Momentary Liquefaction
RESIDUAL LIQUEFACTION
Conducts mathematical modeling for assessment of residual liquefaction potential of seabed due to wave-induced cyclic shear deformations.
Momentary Liquefaction
SINKING OF GBS
Tailored for gravity-based structure (GBS) design on liquefiable soil. Assesses the sinking risk of GBS, calculates the floatation/sinking velocity, ultimate sinking depth and sinking time if applicable.
Momentary Liquefaction
SINKING/FLOATATION OF PIPELINES
Tailored for pipeline design in liquefiable soil. Assesses whether a given pipeline has the risk of floatation or sinking in a liquefied seabed due to waves, and calculates the floatation/sinking velocity, ultimate sinking depth and floatation/sinking time if applicable.
Momentary Liquefaction
SINKING OF 3D INDIVIDUAL BLOCK
Tailored for individual blocks (armour blocks, sea mines, anchors, etc.) on liquefiable soil. Assesses the sinking risk of the block, calculates the sinking velocity, ultimate sinking depth and sinking time if applicable.
Momentary Liquefaction
SINKING OF 2D INDIVIDUAL OBJECTS
Tailored for individual elongated/large objects resting on liquefiable soil. Assesses the sinking risk of the block, calculates the sinking velocity, ultimate sinking depth and sinking time if applicable.
