Project summary

Availability of ice fields and icebergs present on the surface of Arctic and Far Eastern seas for the major part of the year and their drifting under the influence of wind and current creates insurmountable obstacles for stationary drilling and production platforms traditionally used for hydrocarbon production in the non-freezing water areas of the Gulf of Mexico, North Sea etc.

The idea to develop engineering structures and systems not resisting the ice and not experiencing the risk of collapse because of collision with the iceberg but deviating from the ice loads by way of transfer from the surface to the more calm deep layers or directly to the sea bottom has found its implementation in the design developments of the underwater-under-ice manned technological drilling and hydrocarbon production systems.

Underwater modules and units where people, mechanisms and systems ensuring functioning of the production process, power supply, control, life support, communication, supply and rescue etc. are concentrated are the components of the technological system. There have not been any analogues to such objects in the world practice.

Objective of the Project:

To conduct scientific research of safety and risk of the underwater-underice technological systems for hydrocarbon production on the deep-water offshore of the Arctic and Far Eastern seas; to offer methods and means to provide the appropriate develop Safety Case Regulations for underwater -underice systems and offer scientifically justified principles to regulate requirements of their safety.

Technical Approach


- To perform a review and analysis of design development on underwater technological systems of civil designation executed recently by Russian and foreign companies.
- To study the operational Western legislation on provision of safety in development of marine oil and gas fields, Norway and Great Britain being taken as primary examples;
- To analyse rules, norms and requirements to safety provision on the Russian nuclear submarines with a view of their modification for application on industrial underwater objects of the oil and gas producing industries;
- To study the scientific -and- methodological approach and experience of specialized foreign companies in the safety assessments of offshore structures with the usage of methods of computer modeling of emergency situations and risk assessment;
- To identify potential dangers on the underice-underwater technological systems;
- To develop a methodology and computer models of the scenarios of occurrence and escalation of emergencies in the systems;
- To perform calculation assessments of industrial, humanitarian, ecological and financial risks;
- To analyze risks with a view to reveal "weak" points in safety and develop measures of their elimination;
- To offer to the supervising agencies a scientific justification of the approach to regulate safety requirements to the underwater-underice technological system.

Expected Results

The final results of the ISTC Project work will be risk assessments with specific recommendations regarding methods and means to achieve the acceptable safety levels of the underwater-underice technological system and submission to the supervising agencies of Russia and of foreign countries of a report justifying the concept of approach to provide safety on the civil underwater-underice manned technological system of hydrocarbon production for analysis and possibility of identification of the regulating requirements to safety.

Hence, the project has an important scientific and technical significance as having no analogues in the world practice with the prospects of further-on commercial usage.

Potential Role of Foreign and Russian Collaborators

The project executors hope for assistance of foreign collaborators in the study of the acting international legislation on safety of marine offshore operations and in establishment of interaction with foreign supervising agencies as well as for assistance of advisory nature in employment of the existing and development of new methodologies and computer models for calculation risk assessments, services in training and mastering of software for modeling the scenarios of occurrence and escalation of accidents on the marine hydrocarbon production objects.

The Russian collaborator "Unexim-Volga" Bank has expressed readiness to cooperation and has documented its agreement to share funding of the project.

Foreign collaborators from scientific centers, institutes, private companies as well as inpidual experts from the USA, European Union, Japan, Norway and the Republic of Korea are invited to participate in the project.
