Presently, offshore projects have moved to a new level. Advanced technologies are employed to develop those oil and gas deposits that were inaccessible in the past. SPAR and FPSO platforms are used to develop deposits at a depth of over 2,000 meters. Versatile technologies, including suction piles, represent a major factor of successful implementation of these projects.Renewable energy sources arouse more interest. Wind energy is a most ambitions area of research. Wind farms may be installed along the coastline or a shelf. Today many offshore projects are implemented using renewable energy sources. Presently, wind power generators represent sophisticated structures having blades with a diameter of up to 150 m. One of the main objectives is to have them strongly attached to the seabed. Suction piles are often used to solve this task. Suction piles minimize the work at sea, and they are used to install both fixed and floating platforms. The authors consider modern constructions used in similar projects and present the history of suction piles and their use in different offshore projects. The authors also analyze the most recent developments in the area of anchor design for suction piles.The area of research covered in the article is highly relevant. Anchors and foundations based on suction piles can be widely used to develop offshore projects in Russia.<br>Рассмотрены современные сооружения различного назначения, возводимые на континентальном шельфе. Описана история возникновения всасываемых свай, опыт их применения в различных гидротехнических сооружениях при обустройстве шельфовых проектов. Рассмотрены наиболее современные разработки анкерных конструкций на основе всасываемых свай.
