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.

Safety and reliability factors, assumed in Russian and international standards, as well as the main provisions of design of offshore oil and gas structures are considered in the article. The reasons for structures destruction are classified. The analysis showed that the main design provisions and methodology of calculations related to provision of safe and reliable operation of offshore oil and gas structures by different standards are not fundamentally different: the required degree of reliability of the structure is set depending on the social and economic consequences of possible hydrodynamic accidents; calculations are based on the limit states design method using partial safety factors; etc. However, the factors accounting the degree of the structure reliability, partial safety coefficients and load combinations coefficients differ in different standards and methodologies.
