Survey activities as part of the Shtokman project
Starting from 2002 Gazprom neft shelf and Gazprom dobycha shelf have fulfilled dozens of survey missions contributing to decision-making on facilities design in the Shtokman gas and condensate field.
- 6 engineering and geological expeditions (including geo-engineering and geo-physical operations);
- 9 engineering, hydro-meteorological and ice expeditions;
- 4 engineering and geodetic expeditions;
- 3 ecological expeditions;
- 1 explosive ordnance disposal expedition;
- 5 complex expeditions.
Surveys have been carried out as part of this activity to install a semi-submerged drilling rig for exploratory drilling. In September 2006 Gazprom successfully accomplished drilling of exploratory well No.7 in the Shtokman field.
Engineering surveys have been carried out for several pipeline route options, potential locations of the LNG plant and onshore facilities deployment. The Teriberka Bay was finally selected as the best option. An explosive ordnance disposal operation has been successfully completed in the Teriberka Bay allowing to seek and destroy nine explosive ordnances including two anchored mines, three depth charges, two plane-launched projectiles and two torpedoes of World War II.
Minesweeping in Teriberka Bay participated by ships of Russian Navy Northern Fleet and Iskatel company
A comprehensive engineering survey has been performed onshore, near the Teriberka settlement, in order to construct the port transportation and technological complex facilities.
In the course of the ice expeditions a set of ice survey operations was performed, the data acquired during previous surveys was consolidated and local specifications were developed on the basis of the ice conditions in the Shtokman gas and condensate field area.
Between 2008 and 2010 Shtokman Development AG also arranged numerous engineering and ecological surveys in the offshore, coastal and onshore zones of the project. The data acquired during the surveys is used for environmental and design studies.
The offshore survey addressed the hydrological behavior, hydrochemical parameters and biological components of the sea. In particular, biological studies focused on all types of plankton: neuston and benthos as well as fish, birds and marine mammals.
Oceanographic, hydrochemical, radiological and hydrobiological studies were carried out using remote sampling and diving equipment as part of the coastal surveys during four seasons of the year in the Teriberka, Dolgaya and Opasova Bays.
Coastal surveys were carried out onshore the Teriberka Peninsula within the area of the onshore infrastructure facilities deployment and their impact. Particular attention was given to archeological surveys – 34 archaeological monuments (a dwelling site with huts and a single hut, camps) of the Neolithic, Early Metal and Medieval Ages were discovered.
A public opinion poll showed that the population in general had a good attitude to the Shtokman project development in the region.
In summer 2010 Gazprom dobycha shelf was performing a comprehensive offshore engineering survey in the Teriberka Bay to design process facilities within Phases 2 and 3 of the Shtokman project. The survey will be resumed in summer 2011.
