Caspian Explorer Drilling Rig Barge (2011-2012)

Kazakhstan Caspian Explorer is submersible drilling rig. The Caspian Explorer is drilling barge manufactured in Kazakhstan for the first time in the history of our country. Specialists from three countries participated in its assembly. First of all, the leader in shipbuilding, the Republic of Korea. The ship's blocks were manufactured in Romania. At the end all units were delivered to Kazakhstan, to Kuryk, as ERSAI became a subcontractor for the final assembly of the drilling barge.

The implementation of this project is one of the important steps in the strategy of the Republic of Kazakhstan in the development of the Caspian shelf. Until today all works on exploration and drilling of the Kazakhstan part of the Caspian shelf were carried out by barges and platforms built abroad. ERSAI Caspian Yard is one of the first production facilities of the onshore infrastructure of Kazakhstan. It successfully implements the assigned tasks to meet the needs of the North Caspian projects and hundreds of qualified Kazakhstani specialists have been trained in these high-tech oilfield services.

The joint efforts of the Kazakh and foreign specialists created the first Kazakhstan offshore drilling rig. Its launch into water marks the beginning of a new base, the preparation and implementation of the development of one of the largest oil fields. In general, the North Caspian project provides great opportunities for the industrial development of our country. Residents of the region, especially the younger generation, thanks to the implementation of such investment projects of offshore oil production, receive opportunities to get new professions. There is an opportunity to improve their skills to the international level, new work places have been creating.

The rig’s length reaches 100 meters. The width is about 40 meters. It is intended for work in shallow water (2.5–5.5 m.) with a maximum depth of wells drilling of 6,000 meters.
