Abstract

This paper describes one of the most challenging off-shore artificial islands construction in the North of Caspian Sea, Kazakhstan. Two 130 m by 90 m artificial island where sheetpiling was employed were constructed for oil exploration. The islands are closed box structures whose front walls are composed of 15 m long sheetpiles and tied to the back sheetpile wall. Sheetpile driving is done by the aid vibro-hammers with low-pressure water jet assistance. The proposed construction site is extremely sensitive environmental area, known as “Special Ecological Zone” and “Specially Protected Zone”. For this reason very strict environmental regulations are implemented in addition to the safety and quality control programs during the construction works. The local water depths at the construction site are in the range of 1 to 2 meter and also subjected to unpredictable annual and seasonal changes mainly due to the very strong wind effect. The logistic works for the site have been carried out from the main office, establishing in Bautino, which is the only urban village in the region and is approximately 350km away from the construction site. Transportation to the construction site is carried out by ships and usually takes 28-30 hours in case weather conditions permit. The construction of two islands was completed successfully in a period of less than 96 days before the scheduled construction period. The oil exploration works are projected to commence in 2003.

Artificial Island Construction in North Caspian Sea, Kazakhstan

New York, New York

This paper describes one of the most challenging off-shore artificial islands construction in the North of Caspian Sea, Kazakhstan. Two 130 m by 90 m artificial island where sheetpiling was employed were constructed for oil exploration. The islands are closed box structures whose front walls are composed of 15 m long sheetpiles and tied to the back sheetpile wall. Sheetpile driving is done by the aid vibro-hammers with low-pressure water jet assistance. The proposed construction site is extremely sensitive environmental area, known as “Special Ecological Zone” and “Specially Protected Zone”. For this reason very strict environmental regulations are implemented in addition to the safety and quality control programs during the construction works. The local water depths at the construction site are in the range of 1 to 2 meter and also subjected to unpredictable annual and seasonal changes mainly due to the very strong wind effect. The logistic works for the site have been carried out from the main office, establishing in Bautino, which is the only urban village in the region and is approximately 350km away from the construction site.
