It is known that BK-20 is the first mini BK platform of Vietsovpetro, a small BK generation with optimal design, low construction and operation cost, assigned by Vietsovpetro to the Scientific Research and Design Institute for carrying out the research and design to develop small and marginal fields. 

BK-20 is designed in the form of unmanned wellhead platform, controlled remotely from host platform CPP-3. The jacket and topside are designed in compact form, in which MSF, topside and Helideck are designed into one block and within 01 crane code of Hoang Sa crane. Total construction volume of platform BK-20 (including piles, jacket and topside) is nearly 2,300 tons, a decrease of more than 30% compared to the total construction volume of BK platforms of Vietsovpetro previously (such as ThTC-1/2/3, CTC-01, RC-9, BK-16, GTC-01, RC-4/5/6). Therefore, the total construction cost estimate of BK-20 decreases by 28% compared to the construction cost estimate of ThTC-3 platform and decreases by 37% compared to CTC-01 platform.

Fabrication of BK-20 jacket onshore

During implementation of the project, in order to timely put BK-20 platform into operation according to the deadline required by the 50^th Vietsovpetro Assembly (30^th October 2019), Vietsovpetro leaders and relevant departments/ units have urgently found ways to accelerate the implementation of the project, such as: speeding up the implementation of design, material and equipment procurement orders is prioritized for deployment in emergency mode, optimizing construction work onshore and offshore, designing additional temporary structural floors on the jacket to serve drilling and installing pine trees right after installing the jacket, looking for available materials in the warehouse of unused works to use in advance for the BK-20 platform… thereby meeting the project milestones. On 2^nd April 2019, the First cut was done for the project and up to 22^nd October 2019, the installation of jacket, topside, shipping connection pipes and underground cables was completed. On 23^rd October 2019, Vietsovpetro's acceptance committee conducted comprehensive acceptance of the BK-20 platform, evaluating that the project was implemented to ensure quality and absolute safety.

Thanks to putting BK-20 platform into operation four days earlier than the plan assigned by the 50^th  Vietsovpetro council, the increase amount in oil production in 2019 is 1152 tons.

Thus, with the successful design and construction of the BK-20 platform, it proves that Vietsovpetro has been very proactive in development orientation and promptly assigned the Scientific Research and Design Institute to study in detail the optimal design solutions for the purpose of developing small and marginal fields during the exploration phase at Block 09-1 and adjacent blocks. BK-20 platform will be considered and applied to design and construction for potential areas such as BK-21, BK-19, RC-10... In addition, for BK-20 project, this is also the first time Vietsovpetro has put into synchronous operation of all items before the deadline, including: BK platform, underground pipes and cables. This proves the maturity of Vietsovpetro in the implementation of BK platform construction projects in particular and EPCI projects in general.
