Engineering design and construction of marine structures in Arctic.
Morstroytechnology suggests efficient solutions for Arctic projects
Sergey Semenov told about engineering design of marine structures in Arctic at the 10th Annual Russia Offshore Conference, which took place in Moscow at 3-4 of March.
Russia Offshore Conference is the leading platform for building partnerships for LNG and offshore projects across Russia. 10th Annual Conference attracted more than 350 delegates from oil and gas industry, and covered every currently developing offshore project in the Russian Federation.
Sergey Semenov told the audience about specific aspects of engineering design and construction of marine structures in Arctic conditions.
Morstroytechnology projects in Arctic include Salmanovskoye field, port Sabetta, Seyaha, production island in the Gulf of Ob, logistic infrastructure in Arctic rivers and others.
Morstroytechnology developed modern probabilistic forecasting methods
to define ice conditions and calculate ice loads on marine structures.
Methods of calculation of ice parameters and ice loads on hydraulic structures developed by Morstroytechnology are approved by “B.E. Vedeneev VNIIG”, JSC, which is entitled to define standards of ice loads calculation in Russia.
To solve the problem of ice formation in water of Sabetta port, Morstroytechnology suggested to build a special ice melting ship. The ship helps to clean the water area from ice by melting. A short video presentation of the ship (in Russian) is available on our web-site.

In Arctic conditions, artificial islands are unnatural obstacles for ice movement in open water area,
and are subject to immense ice loads.

CONCLUSIONS
http://www.morproekt.ru/ 1827.02.2015
1. Engineering design of infrastructure in Arctic requires in-depth analysis and
planning of supply logistics for construction materials, equipment, and
personnel. Construction of additional supportive infrastructure might be
needed.
2. Artificial islands are a special area of focus in exploration of Arctic. Research
and improvement of techniques of artificial islands’ construction will allow
technological breakthrough for Arctic projects.
3. Ice and ice loads have substantial impact on marine structures. Modern
methods of ice loads calculation may change significantly the type of marine
structure and construction costs.
4. Permafrost condition also has great impact on structures. Depending on
situation it may influence both positively and negatively.
5. Experience and knowledge acquired by Morstroytechnology allow to solve
tasks of any complexity in Arctic conditions and optimize construction costs.
