toray-modec-fpso-repair Toray Industries has developed a carbon fiber reinforced plastic-based repair technique along with MODEC. The technology is for floating production, storage and offloading (FPSO) and floating storage and offloading (FSO) systems that MODEC designs and builds and for which it provides operation and maintenance services. Toray has jointly developed a repair technology using carbon fiber reinforced plastics and has obtained approval from the American Bureau of Shipping (ABS) as a standard repair method for thickened parts due to corrosion.

Need for New Construction Method


Since maintenance of FPSO / FSO is carried out while continuing oil and gas production at sea and only repairs with steel materials are permitted. It has been desperately desired to require a new construction method that makes easy to bring in materials and equipment which does not involve fire work.

Toray has a patent for a vacuum assisted resin transfer molding (VaRTM) repair technique that can be applied to a narrow work site, and Toray has been considering applying the technology to repair of FPSO / FSO in the field of floating marine oil and gas and production equipment including FPSO.

New Repair Technique Using Carbon Fiber Fabric


Toray has been working with MODEC and the two companies have jointly developed a repair technique that uses a dedicated carbon fiber fabric with high strength and high elastic modulus which makes it easier to carry in materials and equipment compared to the conventional repair method using steel materials, and requires a small number of people and a short construction period. In addition, since it does not involve fire work, it can be expected that the impact of repair work on oil and gas production will be minimized.

In the medium-term business program "Project AP-G 2022", Toray will focus on a further improvement on Carbon Fiber Reinforced Plastics business and strengthening its design and proposal capabilities for material systems and will operate in growth markets. Toray will keep leveraging the power of materials to change the world by strengthening collaboration among Group companies while catering swiftly to market needs.
