Laboratory of Marine Engineering and Geophysical Research of the Continental Shelf

Most studies carried out in the laboratory are closely related to the geophysical problems emerging during the early stages of off-shore oil and gas fields’ development. These problems include experimental estimations of mechanical properties of bottom sediments, construction of the model of effective properties of these sediments, and analysis of mechanical behavior of offshore infrastructure facilities subjected to external influence caused by seismic events and seawater movements. 


Laboratory of marine engineering and geophysical research of the continental shelf was created in 2019 as a collaboration between Moscow Institute of Physics and Technology, the Schmidt Institute of Physics of the Earth, and Lomonosov Moscow State University. Most studies carried out in the laboratory are closely related to the geophysical problems emerging during the early stages of off-shore oil and gas fields’ development. These problems include experimental estimations of mechanical properties of bottom sediments, construction of the model of effective properties of these sediments, and analysis of mechanical behavior of offshore infrastructure facilities subjected to external influence caused by seismic events and seawater movements. The solution of the problems considered in the laboratory will lead to a positive effect on offshore fields’ development efficiency, decreasing the costs of infrastructure construction and ecological risks.



Development of experimental setup for mechanical properties characterization.

The bottom sediments are characterized by complicated rheological properties including plasticity and viscosity. At the same time, there are limited ways to analyze these properties of sediments’ samples related to in-situ conditions. The creation of an experimental complex for mechanical properties characterization is among the priorities of the laboratory research. Usage of bottom samplers is essential for methods being developed: the sampling process itself is used for estimating general rheological properties of bottom sediments, while the samples are studied in detail using a multi-level ultrasonic scanning technique developed by laboratory members.

Model of mechanical properties of bottom sediments

The data obtained for bottom sediments’ samples are combined with seismic data in order to construct three-dimensional models of effective mechanical properties. Methods of petro-elastic modeling are implemented for this problem.

Infrastructure stability analysis.

Models of effective mechanical properties of bottom sediments are used for analyzing the mechanical response of seafloor and infrastructure facilities constructed on this floor to external effects. Infrastructure behavior under the effect of seismic events and strong waves is particularly analyzed.
