How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Background: The Kazakh sector of the Caspian Sea faces problems of economic efficiency, environmental sustainability, and operational safety. This necessitates the development of an innovative oil production platform. Within this framework, it is proposed to create an unmanned platform with minimal technological equipment, designed for use as a satellite platform in projects on the northern Caspian Sea shelf. The development of an ice-resistant platform is a key task for successful oil production in ice conditions. Aim: The research is aimed at developing an ice-resistant platform design capable of withstanding static collisions with ice floes. The objective of the research is to develop a modernized autonomous oil platform suitable for use in the northern part of the Caspian Sea. Materials and methods: Existing offshore ice-resistant platforms were analyzed, including the Varandey terminal (Russia), Bohai Sea (China), Filanovsky (Russia), and Bufart Sea (Canada). Ice loads were calculated in accordance with the international standard ISO 19906. An analysis was conducted demonstrating the ability of the caisson structure to withstand static loads from ice floes. Results: The modernized platform design and the method of fixing it to the surface using suction columns and pile fastenings demonstrated the ability to withstand various loads in compliance with international safety standards, including static loads from ice floes. Conclusion: The calculations and analysis confirm the feasibility of investing in the development of a modernized autonomous oil platform with improved ice resistance and meeting all safety requirements for operation in the northern part of the Caspian Sea.
