Asia's first cylindrical FPSO vessel completes hull construction



China's new self-developed floating production, storage and offloading (FPSO) vessel has completed the construction of its main hull structure, in QIngdao, China National Offshore Oil Corporation (CNOOC) said on Thursday, marking a breakthrough in the country's development and manufacturing capability for ultra-large offshore oil and gas equipment.

The vessel, named Haiyang Shiyou 122, is also Asia's first cylindrical FPSO, which integrates the functions of crude oil production, storage and external transmission.

With a maximum diameter of about 90 meters, the vessel has a main deck area equivalent to 13 standard basketball courts and a maximum storage capacity of 60,000 tonnes of oil, enabling continuous operation at sea for 15 years without returning to the dock.

"Compared with the traditional ship structure, the Haiyang Shiyou 122 adopts a new cylindrical structure design, which saves steel consumption but outstands in overall stability and the ability to withstand bad sea conditions, Nie Jiaqiang, construction manager of the vessel, told China Media Group.

The project team also utilized 3D simulation in construction, which enabled the successful closure of hull parts at one go with a dimensional tolerance of less than 6 millimeters, reaching the international advanced level, according to Shu Wei, head of the project general contracting.

Offshore Oil Engineering Co., Ltd. is a listed company controlled by China National Offshore Oil Corporation. It is the only large general contracting company in China with capacities to undertake the design, procurement, construction, offshore installation, commissioning and maintenance of offshore oil and gas development projects, as well as the liquefied natural gas, offshore wind power, refining and chemical projects, etc. It is also one of the largest and the most competitive EPCI (engineering, procurement, construction and installation) contractors of offshore oil and gas projects in the Asia-Pacific region. The Company is headquartered in Binhai New Area, Tianjin. It was listed on Shanghai Stock Exchange (Stock Short Name: COOEC, Stock Symbol: 600583) on February 2002.

The Company currently has more than 9,000 employees, and has built an all-round, multi-level, and wide-ranging professional team competent for EPCI projects. It has the world-class qualifications and has established the operating procedures and management standards in line with international standards. The overall design level of the Company has reached the advanced design level in the world. The Company possesses the large offshore engineering manufacturing bases in Tanggu, Tianjin City, in Qingdao, Shandong Province, in Zhuhai, Guangdong Province, etc., with a total area of nearly 4 million m2. The layout of such bases stretches across the South China and the North China, involves the mutual supplementary functions, covers both the deep and shallow water areas and faces the whole world. The Company has a professional offshore construction fleet consisting of 19 vessels, including Class 3 dynamic positioning deepwater pipelay vessels, 7,500t crane vessels and other vessels, so that the offshore installation and pipe-laying capacity of the Company is in the leading position in Asia.

After more than 40 years of construction and development, the Company has clearly defined the vision of "building a world-class engineering company with Chinese characteristics" and the development strategy of "taking the development of the EPCI capacity as the only core with design as the main driving factor, the operation management capacity and the technology leading capacity as the two bases, the internationalization, deepwater engineering and new industrialization as the three development directions, and the talents, markets, costs, risk control and information construction as the five important aspects". It has systematically developed the ten major equipment with " large lifting and pipe laying vessel series", "1,500m deepwater operation ROV series", "construction site and construction equipment" and others as the core, and the ten major technologies with "deep water floating platform technology", "underwater system and product technology", "ultra-large offshore structure and modularization technology" and others as the core. The Company has successively provided high-quality products and services to many Chinese and foreign owners, such as CNOOC, ConocoPhillips, Shell, Saudi Aramco, Petrobras, Technip, MODEC, FLUOR, with its business in more than 20 countries and regions.
