On February 13, 2017, the world's most advanced ultra-deepwater double-drilling tower semi-submersible drilling rig "Blue Whale No. 1" was delivered in Yantai, Shandong Province. The platform is equipped with the world's leading Siemens DP3 closed-loop power system. "Blue Whale No. 1" was built by CIMC Raffles Offshore Engineering Co., Ltd. (CIMC Raffles). It is based on the basic design of Frigsta D90. It is the world's largest semi-submersible drilling platform with deep water depth and drilling depth. % of the sea, classified by the Norwegian Classification Society. The platform won the Best Drilling Technology Award from World Oil magazine in 2014 and won the Best Design Highlights Award at the US OTC International Petroleum Industry Exhibition in 2016. The Siemens DP3 closed-loop power solution provides energy and safety for the Blue Whale 1 drilling platform, which reduces fuel consumption by 11% and reduces nitrogen oxide emissions by 20% and carbon dioxide emissions by 20%. When the generator on the platform suddenly fails, through the DP3 closed-loop power solution, the standby generator can be started in a very short time, so that the platform can obtain continuous power, ensure safe and stable operation, and reduce the maintenance cost of the mainframe by 50%. Siemens' power pack system capacity for "Blue Whale 1" is equivalent to the electricity consumption of a city of 500,000 people. Siemens' advanced power pack system covers “one-stop†solutions from low-voltage switchboards for high-voltage switchboards to transformers, drilling inverters, propulsion drives and propulsion motors, making the platform more stable, reliable and efficient. The year is galloping on the sea. Siemens launched DP3 closed-loop power technology in 2010 and is the first in the world to apply this technology to real ships and obtain classification society certification. This technology can effectively reduce host operation and maintenance time, improve host operation flexibility and fuel economy, and reduce greenhouse and harmful gas emissions. At present, Siemens DP3 closed-loop power technology has been integrated and applied in more than a dozen real ships around the world.
