Abstract

In this study of the evaluation of wave impacts on a gravity base structure (GBS) which is moored to berth No. 5 of the Centre of construction of large-capacity marine structures (CCLMS). It was identified five main wind directions that can be dangerous for the construction of CCLMS: East direction (E) South-East (SE) South direction (S), Southwest (SW), West (W) and Northwest (NW). According to the results of statistical processing of extreme storms of the 30-year period, two most dangerous directions of unrest were chosen-the Eastern direction (B) and the South-Eastern (SE) direction. Using a numerical model ARTEMIS, it was received wave field in the waters CCLMS near GBS reading for different sea levels. The simulation results showed that the wave heights affected the structure can reach 2.4 m.

Highlights

The center for the construction of large-capacity marine structures (CCLMS) is planned to be built in the area of Belokamenka village on the Northern shore of the middle knee of the Kola Bay between the Belokamenka and the Bolshoi capes

It is known that in the waters of the Kola Bay may excitement due to penetration into the bay of waves coming from the Kara sea, and wind waves of the local acceleration

Summary

Introduction

The center for the construction of large-capacity marine structures (CCLMS) is planned to be built in the area of Belokamenka village on the Northern shore of the middle knee of the Kola Bay between the Belokamenka and the Bolshoi capes. This plant in the dry docks will build a concrete gravity base structures (GBS). Readymade modules on self-propelled trolleys will be transported to dry docks, where modules will be transferred to GBS with subsequent integration into a single line of the gas liquefaction process (Fig. 1).
