Abstract. The unique results of complex long-time scientific program aimed to the study and development of the Arctic region are presented. A large-scale drilling project for engineering-geological wells was implemented on the Laptev Sea shelf during the 2023 field season. The work was carried out from two drilling vessels of JSC AMIGE: RV Bavenit, which carried out the stratigraphic research program, and RV Kimberlite, which carried out most of the drilling. The purpose of the work was to study submarine permafrost. Extremely difficult engineering and geological conditions of the Laptev Sea have been confirmed, including permafrost soils, gas-saturated sediments, and abnormally high reservoir pressure (AHRP). Permafrost was found in six of the seven drilled wells. Keywords: shallow drilling, engineering -geological conditions, Laptev Sea, shelf, submarine permafrost, seismoacoustic surveys
