On March 30, the world's largest dynamic positioning system shuttle tanker "NS PIONEER", designed and built by China, was officially delivered in DSIC of China State Shipbuilding Corporation Limited(CSSC). The upgrading and application of relevant equipment technology has achieved a double breakthrough in the domestic shipping industry and shipbuilding industry. Xia Qinglong, President of CNOOC LTD., Liu Daping, president of CNOOC Petrochemical Import and Export Co., LTD., Zhu Maijin, General manager of Cosco Shipping Energy and Transportation Co., LTD., Yang Zhizhong, He Xu, leaders of DSIC and other relevant units attended the naming and delivery ceremony. Ms Liu Min cuts the cable for the new vessel, which she named "NS PIONEER".
"NS PIONEER"
"NS PIONEER"is the tanker commissioned by China Shipping Petrochemical Import and Export Co. LTD to be tailormade by DSIC for the transportation of Chinese share oil in the world's largest deep-water oil and gas field——Buzios and Mero oil fields in Brazil. With complete independent intellectual property rights, it is another successful work of DSIC and it marks the return of DSIC to the shuttle tanker construction market. The vessel has a payload capacity of 155,000 tons, a total length of 279 meters, a width of 48 meters and a depth of 23.7 meters. It adopts industry-leading DP dynamic positioning technology (DP2) and a new generation of bow loading system, providing stable position control and higher oil lift safety. The vessel is the first new DP tanker to be built according to the latest version of Petroleo Brasileiro SA, and is the largest class of DP tanker built to this standard in the world. With low energy consumption and high maneuverability, the ship meets Tier III standards for nitrogen oxide emissions and EEDI Stage 2 in the Ship Energy Efficiency Design Index. Its carbon emissions per deadweight ton miles are about a quarter lower than the baseline value, and it can reduce carbon dioxide emissions by nearly 7,000 tons per year, equivalent to planting 1,200 trees.
Tip: What is the DP system?
The DP system is a positioning method that automatically maintains a floating device at sea without using mooring. It reduces the need for complex anchoring operations and is not limited by the length of the mooring line. It can operate in water depths of more than 1000m. The DP2 system is designed to provide a safe distance between the shuttle tanker and the floating production storage and offloading unit (FPSO), allowing it to move relative to the FPSO for safe operation.This vessel is the first shuttle tanker in China to be equipped with a closed-loop power distribution system that meets the requirements of DP2, which can reduce the number of generators online at the same time, improve the operation economy, reduce nitrogen oxide, sulfide and carbon dioxide emissions, reduce noise, and create a comfortable working environment for the crew. With a loading rate of up to 9,000 cubic meters per hour, the bow loading system is equipped with a variety of operating modes including single point mooring, offshore terminal, multi-point mooring and external transport. Combined with the DP2 system, loading and unloading operations can be carried out safely and efficiently from various offshore terminals and vessels.In the face of complex system installation and commissioning, DSIC overcame many difficulties in the leading ship test and successfully sailed back to sea 3 days ahead of schedule, creating the best result of the same level in China.
After delivery, the vessel will go to Brazil to carry out oil extraction operations, providing guarantee for CNOOC's deep-sea oil extraction transport in international waters. The average operating water depth of ultra-deepwater oil fields in Brazil is about 2,000 meters, and the sea area where the climate is changeable, the wind and waves are large, and the environmental conditions are harsh. Therefore, the dynamic positioning function of oil tanker in oil extraction operation is highly required. Yang Zhizhong, Party Secretary and Chairman of DSIC said:"NS PIONEER" has fully independent intellectual property rights. It is the first Suez-class shuttle tanker ordered by domestic ship owner. Like a "floating oil pipeline" laid in the Southern Ocean,“NS PIONEER” will continuously transport deep-sea crude oil, providing a solid guarantee for CNOOC's deep-sea oil transport in international waters.
The official commissioning of the "NS PIONEER" is a strong practice of CNOOC's new development pattern of "two cycles" based on the international and domestic development, and also another milestone in the implementation of the strategy of "National oil, national transport, national wheel and national manufacturing". Liu Daping, chairman of CNOOC Petrochemical Import and Export Co., LTD., said, "CNOOC will become the first Chinese enterprise to operate DP tankers in both international and domestic waters, achieving a breakthrough of 'zero' for Chinese shipowners in the international DP tanker market. In the next step, we will continue to fulfill the mission of 'The heart of the blue sea, energy to serve the country' and the solemn commitment of 'increasing reserves and production' to provide a more powerful guarantee for national energy security and the construction of a maritime power." |
