description: This dissertation discusses some issues of improving the designs of the supporting foundations of offshore platforms using concrete.
Tasks that were solved during the study: Analysis of the experience in designing, constructing and using for their intended purpose OGT (support blocks of gravitational type) MLP, operated in severe climatic conditions of the far North: 
1. Determination of the basic conditions for the operation of the support bases of the gravitational type of sea ice-resistant platforms of the Arctic shelf. 
2. Identification of promising areas for improving the design of support bases using reinforced concrete. 
3. The selection of characteristic reinforced concrete elements to assess their temperature and thermal stress at the concreting stage.
4. The statement of the problem of studying the temperature regime and the thermal stress state of reinforced concrete structures of slab type to optimize the conditions of their concreting in order to limit temperature cracking.
5. Computational studies of the temperature and thermal stress state of reinforced concrete slabs at the concreting stage.
The practical significance of this study is to justify the need to take into account the temperature stresses that arise when concreting slab reinforced concrete elements of support bases of gravity type, similar to the support base of the Arctic LNG platform 2. The results can be used in the design of support bases in climatic conditions of the far North.
Based on the analysis of the results of test calculations, the following conclusions can be drawn:
ï­ to ensure temperature crack resistance of monolithic reinforced concrete structures as part of the support bases of offshore ice-resistant platforms, it is necessary to carry out a set of measures to regulate the temperature regime;
ï­ crack resistance of monolithic reinforced concrete structures can be violated during the construction period;
ï­ for monolithic reinforced concrete structures of plate type with a plate thickness of more than 0.5 m, an assessment of temperature crack resistance should be carried out;
ï­ optimization of monolithic reinforced concrete structures should be carried out taking into account the stresses of the construction period caused by temperature technological influences.
The analysis showed the effectiveness of the use of platforms of support bases of gravitational type. During their design, the Choice of certain technical solutions depends on many factors, of which it is necessary to single out primarily: the purpose of the platforms, the climatic conditions of operation, the availability of production facilities and building materials.
