Presentation on the First starting complex of the gas main Kekiyak-Atyrau took place in Atyrau. Russian company Stroytransgaz was chosen as the general contractor and played the essential role in realization of the project.
The Customer of the project is ZAO North-West Pipeline Company Munai-Tas. The founders of the company are: ZAO National Company KazMunaiGaz (51% of shares) and TOO Chinese National Oil Company Int. in Kazakhstan (49% of shares). The gas pipeline shall connect oil-pumping station Kenkiyak with oil-pumping station Atyrau of ZAO KazTransOil and will extend to export terminals of the Caspian pipeline consortium and to the oil pipeline Atyrau-Samara. The consumers of the system will be all oil producing companies located along the route of the oil pipeline Kenkiyak-Atyrau. The main of them are: CNPC Aktobemunaigaz, Kazakhoil-Aktobe, KazakhOil-Emba, KazakhTurkMunai, etc.
At the presentation the prime-minister of the Republic of Kazakhtan Imangali Tasmagambetov mentioned that Kazakhstan had obtained not only the object of infrastructure, but it had connected Kazakhstan oil fields with the world markets.
The construction of the pipeline began in the middle of 2002. The obligatory condition of the contract concluded with OAO Stroytransgaz was the paragraph on attraction of a Kazakhstan company as subcontract organization for carrying out of 53% of construction. ZAO KazStroyService which is the affiliated company of the National Company ZAO NK KazMunaiGaz has become the subcontract organization. NIPI CaspiyMunaiGaz (Atyrau) worked out basic design estimates. The detailed design was prepared by GAZNIIPROJECT (Samara) which is the affiliated company of OAO Stroytransgaz. Engineering supervision on pipe supply and construction of the object on the whole was led by an independent British supervision company Moody International Ltd. The works were held at various sites by seven spreads with the help of subcontractor organizations of OAO Stroytransgaz and ZAO KazStroyService. The supplied pipelines were manufactured by the plants of China and Russia.
The Project was fulfilled following speeded up strategy. Its construction became an original creative laboratory for testing and introduction of new technological methods, which has not been previously used in the field of oil and gas facilities construction sector of Kazakhstan. That enabled to complete undertime the construction of the linear part of the Kenkiyak-Atyrau oil pipeline. The average speed of pipeline construction was 7-8 km per day.
During construction a special attention was paid to ecological aspects, such as rational nature management, reduction of negative influence of production activity on environment and environmental safety control. New engineering approach was used to maximally minimize the risk of nature pollution. For example, to cross the Ural River a method of horizontal directional drilling was used, that precludes detrimental effect on environment and enables to keep river-beds and river-sides in their natural state. Laying of the pipeline was carried out at the depth of 19, 49 m under the river-bed and the length of the borehole tunnel drilled was 841,18 m. As a result of coordinated efforts, the trenchless variant of pipeline crossing over the major water obstacle was successively carried out.
Over 470 units of special construction machinery and more than 1000 men were engaged at the construction of the linear part of the Kenkiyak-Atyrau oil pipeline.
The initial capacity of the pipeline will be 6 million tons of oil per year with subsequent increase up to 12 million tons per year. The length of the Kenkiyak-Atyrau oil pipeline is 448,8 km.
Construction of the Kenkiyak-Atyrau main oil pipeline is a crucial stage in improvement of the Republic’s transport infrastructure and beginning of the future transcontinental oil pipeline “Western Kazakhstan-China”.
