KRISO Takes the Lead in Digital Transformation of Shipbuilding and Marine Industry

▶ KRISO developed a structural digital twin platform for shipbuilding and marine industry

▶ A basin model test method based on the structural digital twin platform was developed for floating offshore structures.

□ The Korea Research Institute of Ships and Ocean Engineering (KRISO, President Keyyong Hong) developed a ‘ship and offshore structure digital twin platform’ for predicting safety of ships and offshore plant structures in a virtual space.

ㅇ The concept of the digital twin is receiving attention in various industries as a technology for verifying safety through simulation under various conditions by equally implementing and linking real-world machines, equipment, and objects in a virtual space.

□ Using this platform developed by KRISO, a model reflecting the detailed structure of an actual ship or offshore structure can be implemented in a virtual digital space to perform interactive real-time evaluation of the conditions of the structure in various marine environments and to predict the changes of the conditions in 10 to 20 years in consideration of the deformation, aging, corrosion, and damage, thereby estimating the remaining service life.

□ Previously, the application of digital twins was difficult because a huge amount of time was required to analyze large amounts of data to evaluate the structural safety of ships and offshore plants under various marine environmental conditions. However, KRISO has developed a method for implementing the reduction of order, which reflects the physically predicted deformations or various numerical analysis algorithms, and thus drastically decreases the time required for the analysis, enabling the implementation of structural digital twins for ships and offshore plants.

□ The excellence of this technology was verified in comparison with model test results obtained from an ocean engineering basin based on a multi-linked floating structures, developed by KRISO.

K-FPSO structural model and structural safety assessment procedures independently developed by KRISO

□ When the technology is applied to actual ships or offshore plants, the structural integrity can be quickly confirmed. This allows for the prediction and prevention of accidents caused by cracks and damage of structures, such as the past sinking of the MOL Comfort and the MSC Napoli container ships. Furthermore, it is anticipated that the technology can significantly reduce the costs and time required for the management and maintenance of actual structures.

□ Principal Researcher, Kangsu Lee said, “We will further upgrade the structural digital twin platform by using the FPSO structural model (K-FPSO), which was independently developed by KRISO.”

 ㅇ K-FPSO, an FPSO structural model developed according to the regulations of the international classification societies, acquired AIP certification from the Korean Register, as its performance for structural analysis and structural safety evaluation was recognized.

    * FPSO (Floating Production Storage and Off-loading): A floating type facility for producing, storing, and off-loading oil. FPSOs are offshore complex structures for extracting crude oil from the seabed in particular offshore regions, producing and storing refined products, and transporting them to other ships.

□ For the commercialization of the source technology of the structural digital twin, KRISO is currently conducting technological exchanges with major companies in Korea and other countries. Through continuous cooperation, KRISO will make efforts to apply the platform to ships or offshore plants.

□ Keyyong Hong, the President of KRISO, said, “The digital twin technology for ships or offshore structures will gain more applications in the future.” He added, “KRISO will do its best to take the lead in the digital transformation of the shipbuilding and marine industry of Korea by advancing digital twin technology and establishing a digital twin center for conducting joint research with universities and companies.”
