[Background] [Purpose of this issue] Using heat flow measurement type pipe monitoring technology and artificial intelligence (AI), grasp in real time the formation state of the adhesion thickness spatial distribution of solid deposits formed in marine resource transportation pipes , assessing the feasibility of future-predictable and innovative sensing technologies. [Results] [Future Prospects] Conservation measures (flow assurance) for flowlines that transport offshore resources such as offshore oil and gas fields and methane hydrates will hinder the stable and economical transportation of products in particular. The most important issue is to grasp the state of accumulation of solid deposits in the pipes.High-precision monitoring of the flow line from the seabed to the sea is essential for advanced flow assurance ? There is no technology that can constantly monitor the condition of the entire long-distance flow line.We performed a test that simulated the heat transfer flow state in the marine resource transportation pipe as much as possible, and quantitatively evaluated the prediction performance of the thickness of deposits in the pipe by the heat flow measurement type pipe monitoring technology.A database of pipe surface heat flux, temperature, scale thickness, etc. acquired for geothermal resource transportation pipes was developed.Based on the spatio-temporal data of deposit thickness, we investigated the method of predicting the future growth of deposits and evaluated the applicability as an IoT-AI tool for operation management in marine resource transportation systems.We will promote the sophistication and practical application of this technology for marine resource transportation piping through joint research and development with companies related to subsea systems.Research representative Fig. XNUMX Heat flow measurement type pipe monitoring technology Fig. XNUMX Scale thickness prediction example Motoaki Morita (Marine Electromechanical Engineering Division) Tomonori Ihara (Marine Electromechanical Engineering Division) Overview of the issues Results and future prospects Implementation system XNUMX.Acquisition of marine big data and promotion of AI analysis research (XNUMX) Examination of AI utilization methods that contribute to technical breakthroughs in marine resource flow assurance
