Recently, according to the information published on the official website of Toray, Japan, the company is also headquartered in Tokyo’s Chuo-ku Mitsui Marine Development Co., Ltd. (hereinafter referred to as "Mitsui Marine") designed, manufactured, and subsequently operated and maintained for floating offshore oil production, When the storage and unloading system (FPSO: Flating Production, Starge and Offloading system) and the floating oil storage and offloading system (FSO: Flating Stage and Offloading system) were repaired, Toray and Mitsui Marine jointly developed a carbon fiber reinforced plastic (CFRP) ) FPSO/FSO repair technology, and as a standard repair method for corroded parts, this technology has been approved by the American Bureau of Shipping (ABS).
The FPSO/FSO system maintenance is carried out while the oil and gas production continues at sea, and originally only steel is allowed for maintenance. Therefore, there is a strong need to develop a construction method that is easy to carry materials and equipment, and does not involve fire protection jobs.
Toray Company has a patent for the use of CFRP vacuum forming methods in narrow work sites, and is considering applying this technology to the fields of floating offshore petroleum gas and production equipment led by FPSO/FSO. In the early stage, we discussed the repair technology suitable for FPSO/FSO system with the world's leading company and Japan's only professional company-Mitsui Marine Development Co.
The repair technology jointly developed this time uses a special cloth made of high-strength and high-elastic carbon fiber. Compared with the traditional repair methods using steel, the materials and equipment are easier to carry, and can be carried in a small number of people in a short time. Carry out construction. In addition, since there will be no pyrotechnics, the impact of maintenance works on oil and gas production can be minimized.
In the mid-term management of the "AP-G 2022 Project", Toray focuses on improving the global position of the carbon fiber composite business and strengthening the design and proposal capabilities of the material system as a key issue, and will promote business expansion and research in growth markets. Technology development.
