The belief that the Caspian Explorer was the only currently operational drilling vessel of its type capable of operating in water as shallow as 2.5 meters in the Caspian Sea led to its acquisition by the company. In an update on Wednesday, Caspian Sunrise said it had received all the required Kazakh regulatory and local shareholder approvals for the acquisition. Further, given the lead times and construction costs, the company did not expect a new competing drilling vessel to enter the market in the next few years. Caspian Sunrise revealed its plan to buy the Caspian Explorer for $25 million back in January 2020. In 2017, the Caspian Explorer was hired out to a KazMunaiGas / Indian state oil company joint venture for $28 million after costs and drilled one exploration well to a depth of 3.5 km. The vessel was conceived of by a consortium of Korean companies including KNOC, Samsung, and Daewoo Shipbuilding. It was assembled in the Ersay shipyard in Kazakhstan between 2010 and 2011 for a construction cost believed to be approximately $170 million. Furthermore, the relevant paperwork has been sent to the UAE to complete the required re-registration of ownership of the Caspian Explorer, following which the acquisition of the asset will complete. In 2018, it was hired out KazMunaiGas for up to $24 million drilling one exploration well to a depth of 1.8 km. The vessel did not operate in 2019. Caspian Sunrise, an oil and gas company with a focus on Kazakhstan, has received regulatory and shareholder approvals for the acquisition of the Caspian Explorer drilling vessel.
